I finally finished understanding the story of DMC 1 - 5. Now that I have, I've finally decided to do a Gravity Falls X DMC story. Shoutout to kirbymaster800 for the idea.

Disclaimer: I don't own DMC and Gravity Falls

The Mystery Twins of Sparda CH 1

"Can you believe it Dipper? It's been 5 years since we've been to Gravity Falls!"

"Yeah...I wonder how everyone's been since?"

The two talking were the 19 year old Dipper and Mabel Pines.

Mabel's brown hair was still as long as ever, but she no longer had her braces on her teeth. As for her clothes, she wore a red dolman loose sleeve that showed revealed her shoulders. Under the sleeve she wore a black singlet and could be seen by her shoulders. On her top, the words Mabel was spelled out because she knitted her name to it. She wore brown pants and regular shoes. Behind her back was a black bag that was as tall as her.

Dipper still wore the hat Wendy gave to him ever since. For Dipper's clothes, he wore a black sleeveless vest and wore a dark blue undershirt. For some reason, he wore black gloves for some reason. And he wore navy jeans and regular shoes like Mabel. He also held a long black suitcase in his hand.

"Can you believe we've been offered to attend college in Gravity Falls!? I'm so excited!" Mabel said.

"I just can't believe Gravity Falls has a college to begin with? I know for fact that for the time we've been in Gravity Falls, not once I've heard about a University there." Dipper pondered.

It was just after both teens graduated high school. They were looking at acceptance letters for the colleges of their choice when a certain envelope caught there eye.

The envelope in question was blood red which was strange enough. But when the twins opened the envelope, the letter itself was mysterious. First of all, the handwriting itself was written in a fond found in the early 1800s, and the letter itself addressed both Dipper and Mabel which was odd itself. Then the cherry on top was that it was an acceptance letter for them to attend a university at Gravity Falls, the college itself was opened ever since the twins left Gravity Falls when they were 13. Which was strange for Dipper because he never once heard anything about to school until now.

Of course Mabel eagerly decided that she wanted to attend the university because she believed it was a chance to finally reconnect with all her previous friends she made during the Summer. After Weirdmageddon, the twins parents didn't allow them to return to Gravity Falls, which was understandable considering the fact that they almost died several times. That being said, the twins now were much older and more mature. After much consideration, their parents allowed them to go. Dipper also wanted to attend the university, but he decided to do so that be with Mabel and protect her. Plus he wanted to find out more about the university itself.

"So Dipper, is there anyone you want to meet up with again?" Mabel asked.

"Ah...There's so many friends that I would want to meet again...I don't know who to choose." Dipper said.

"What about Pacifica?" Dipper turned her head to Mabel.

"Huh?"

Mabel had a sly grin. "Don't deny you didn't have any feelings for her!" Mabel said.

"That's because I don't have feelings for her!" Dipper argued.

"Sure you don't...Tell me, if you saw her again, what would you say to her?" Mabel.

Dipper rolled his eyes.

"I don't know Mabel...Hi Pacifica...It's been a long time?" Dipper answered.

Mabel frowned.

"Boo!" Mabel said while doing a thumbs up upside down with both hands.

"Come on Dipper! You got to show some more compassion then that! It's been 5 years! I know you love Pacifica!" Mabel stated.

"Look Mabel, its true I do like Pacifica, but...Its just that. I don't know if I can just date her."

"Dude, your 19 and you don't have a girlfriend yet." Mabel argued.

Dipper just stared at Mabel. "Mabel, I know your not talking. We're the same age and you don't have a boyfriend yet."

Mabel sighs.

"Dipper, ever since our summer in Gravity Falls, I've finally realized why I don't have a boyfriend." Mabel said.

"Because most of the boyfriends you wanted were gnomes, clones, a mermaid, a guy who kisses puppets, and Alexander Hamilton?" Dipper said while smirking.

Mabel looked away in embarrassment. "...There's that." She looked to Dipper again. "But...I've come to realized that most of what happened was my fault. I guess it was because I was 12 at the time, but it still doesn't excuse how much a total asshole I was during summer." Mabel said.

"Come on Mabel, you weren't an asshole...That much." Dipper said sheepishly.

"Still, even you had to admit I wasn't always the best sister to you. For god's sake, the apocalypse was caused because I was being such a child!" Mabel lamented. Even though it was 5 years since Weirdmageddon and the defeat of the infamous Bill Cypher, Mabel still felt bad for starting it. Hell, she even created a diluted fantasy world because she couldn't accept reality and it nearly killed her family.

Dipper placed a hand on Mabel's shoulder.

"Hey, it wasn't your fault alright. Bill tricked you, like how he tricked me, even Gruncle Ford. In the end, it took all of us to finally defeat Bill and now that pyramid asshole, so quick beating around the past." Dipper told Mabel while smiling.

Mabel returned with her smile.

"Thanks Dipper, even at my lowest points, you never give up on me." Mabel said.

"Sure thing! That's what siblings are for!"

The bus then stopped as it was picking up a passenger. As soon the passenger came into the bus, the bus started driving again.

"Excuse me, I would like to sit here if you don't mind." Said a female voice.

Dipper and Mabel turned to a woman their age.

She has dark, chin-length hair on both sides of her face and she has a fringe that reaches her eyebrows. She has a strange scar that runs across her nose. Her left eye is red while her right eye was bluish-green. She wears a schoolgirl outfit with a short white blouse that bares her midriff and sleeves that reach just past her elbows. She also always has a necklace with a red gem on it.

"Oh hi! You look like our age! Are you attending Gravity Falls University?!" Mabel asked politely.

The dark haired woman facial expression didn't change. "Yes I am. Like I said earlier, I would like to sit here." The woman said.

Mabel just turned to Dipper. Dipper just shrugs his shoulder as he moved to the middle. The woman walked to the end of the seat where the window was.

"Excuse me, you didn't say thank you to my brother for moving." Mabel stated.

The woman turned to Mabel.

"And why should I? I don't know either of you." The woman spoke coldly.

That made Mabel mad.

"Why you bit-"

Dipper grabbed Mabel before she could do something stupid.

"Perhaps we gotten off the wrong foot. My name is Dipper Pines, my twin sister is Mabel Pines." Dipper introduced himself and Mabel.

"And what's your name?" Dipper questioned.

The woman just stared at them for a minute.

"I won't give you two my real name. However, you can call me whatever name you guys want." The woman told them.

"Come on, were going to be in the same school together, we should at least get to know each other." Dipper told her.

The woman just scoffs.

"I have my own agenda for coming to the university. And it certainly doesn't involve you or your stupid looking sister." The woman told them. Though the insult made Mabel more mad.

She slowly turned to Dipper with a smile that promised pain to anyone besides Dipper.

"Dipper...Can I teach her a lesson?" Mabel asked politely, but Dipper knew it was a front for her anger.

"Mabel, you're not going to kill her, calm down." Dipper reprimanded his twin sister.

The bus came to a stop.

"THIS STOP IS GRAVITY FALLS!" The bus driver stated.

The black haired woman got up and walked away from the twins.

"Hopefully we never see each other again." The woman said.

Mabel then gave her the middle finger while she wasn't looking. Dipper just shook his head.

"At least we're finally back in Gravity Falls." Mabel smiled at her brother.

"Yeah, as much as I want to reunite with everyone, we need to head to school ASAP otherwise we'll be late." Dipper stated.

Both twins gotten their stuff and got off the bus.

Unknown to the twins, someone was watching from above. The figure was standing on a long tree branch. Holding a strange sword. It is a curved blade organic-looking spinal column instead of the one that appeared mechanical, with some bony covers below its guard. It also has some large jewels.

"So those twins are their descendants...Better see what they are capable of." The lone figure said, before disappearing.


Dipper and Mabel were running to the opened gates of the University.

"Holy crap! It's huge!" True to Mabel's word, the University itself was large. It was even bigger than the Northwest Mansion itself! And it was surrounded by a forest that was just as grand.

"How the hell did we not discover this when we were here?" Dipper questioned. The University itself looked old fashioned, like it was opened in the early 1900s.

"Who cares?! Were going to be spending the next four years here!" Mabel stated, excited.

"Mabel, I hope you realize that college isn't all about goofing off, you need to take your work seriously if you want to have a successful career in the future." Dipper said calmly.

Mabel just blows a raspberry in front of Dipper.

"Yeah yeah Dip, I'm just so pumped up! We're back in Gravity Falls and not just for the summer! It would be better if Candy and Grenda were here. Imagine all the fun we could have together and we can make up for so much lost time!" Mabel said.

"Look Mabel, I understand you miss them, but its not likely we'll see them here in the campus. After all, some people just drift apart, we made some friends back in highschool."

"We?" Mabel questioned.

Dipper looked at Mabel in annoyance. But he sighs. "Okay, YOU made some friends back in highschool, but everyone have different wants and dreams. For all we know, Candy and Grenda could be at some different university and-"

"Oh my god! Dipper?! Mabel?!" Called out a familiar voice.

Both twins turned to the voice.

The woman in front of them ran to them.

She had long black hair, but she tied them into long pigtails. She wore round glasses, a mint green hoodie with a white horizontal line, dark gray pants, and black shoes.

Her appearance made Dipper blush, while Mabel looked really happy.

"Candy?! It is you! It's been so long!" Mabel ran and hugged Candy. Both girls were then squealing in joy.

Mabel stopped hugging Candy. Both girls held each other hands.

"You're attending Gravity Falls University too?!" Mabel stated.

"Yep! Me and Grenda are."

She then looks to Dipper, who is caught off guard by her stare.

"Oh! H-Hey Candy...Long time no see am I right?" Dipper said nervously.

Candy turned her eyes back to Mabel.

"Mabel...I can see Dipper matured a lot, but he's still a nervous wreck." Candy said.

That made Mabel chuckle a little. "Damn right. He still can't land himself a girlfriend!" Mabel teased.

"I HEARD THAT!" Dipper yelled out.

"Oh...So he's still single is he?..." Candy said as she was playing with hair.

"Why do you ask?" Mabel asked.

"Oh...No reason..." Candy told Mabel.

Mabel was then taken from behind and wrapped into a hug.

"Mabel! We missed you so much!" Said another familiar voice.

She was taller then Dipper, Mabel, and Candy, she had brown hair that was tied into a small ponytail, she wore a pink tank top, blue jean shorts, and regular sneakers.

"Hey Grenda! Nice to see you too! It's funny! Dipper said there was a chance we wouldn't see each other again, but here we are!"

This time all three girls squeal in joy.

"Look guys! As much as I hate to ruin this fun reunion, we need to head into the university otherwise we'll be late!" Dipper stated.

"Oh crap! He's right! We can catch up when were inside!" Mabel said.

Grenda puts Mabel down as the four rush into the university so they won't miss orientation.

Later...

The four were sitting in a large auditorium.

All chatting died down when the headmaster walked to the stage.

The man in question was a tall, pale-skinned bald male adult. He is dressed in a rather simple minister like suit that is completely black.

But Dipper noticed something strange, and it was the man's eyes. His eyes were the same colors as the black haired woman they met on the bus.

The man grabbed a mic and began his speech.

"Hello...Wonderful students. I would like to congratulate you all for being accepted to this university. For the next four years, I headmaster Arkham, will be in charge of all of you. Now, there are some things I need to address. As I understand, there have been 'rumors' about missing students everywhere. Let me assure you that these are only just rumors, what happened to those freshman is that they have broken very delicate rules in the university and have been expelled. Make no mistake, if you violate the rules I have set in this campus, you will be punished severely." The man clears his throat.

"Now that we cleared the issue, you may all leave, for those who are living on campus, your schedules have your room numbers. If you have any questions, please ask our guidance counselors, if that's all, have a good day and welcome to Gravity Falls University."

Arkham stated.

The students in the auditorium got up and was heading out.

"Wow, the headmaster sounds strict." Candy said.

"I know, people like him are the worst." Mabel pouts.

"You know, I've been meaning to ask, what's with the luggage you and Dipper are holding?" Grenda asks.

Mabel looked at the two nervously.

"Oh...It's nothing...Just some memento shit our parents gave us" Mabel answered quickly.

"So Dipper...Mabel...How come we haven't seen you for five years? We missed you guys so much." Candy said to the twins.

"Blame our parents. After that shit with Weirdmageddon, they basically banned us from returning to Gravity Falls." Mabel stated, a bit huffy.

"Come on Mabel, I can understand where they were coming from, we were almost killed several times during our summer. Mom and Dad were concerned for us." Dipper said.

Mabel rolled her eyes, but she understood what Dipper was talking about. "I know...I just wished we came back sooner."

"Well don't worry guys! Because we can make up all this lost time!" Grenda said while smiling.

"Yeah! We can gossip on all types of things!...Like relationships!" Candy added.

Mabel smiled again.

"True! I have to tell you our time in high school! But right now, we need to get to out rooms!"

"Cool! Me and Candy are sharing a dorm." Grenda said.

"Lucky...Me and Dipper have different dorms." A jealous Mabel said.

"Thank god. I didn't want to spend four years sharing the same room with you." Dipper smirked.

Mabel punched him in the arm.

"Shut up! I'll see you guys later!" Mabel said.

"BYE!" Candy and Grenda yelled out.

Mabel and Dipper went their separate ways to go to their dorms.


With Mabel...

"211...212...Ah! 213!" Mabel opened her room, expecting to be alone, unfortunately, she wasn't.

"Mabel Pines!? Your my dorm mate!"

Mabel's eyes widen.

"Pacifica Northwest!"

The woman still had her luscious, long blonde hair, and her eye make up. She wore a purple polo shirt, a pearl necklace, beige colored pants, and white shoes.

"You have got to be kidding me!"

With Dipper...

"442...443...444!" Dipper opened her room, and he was greeted to a peculiar sight. The same woman he met on the bus, had a pistol aimed at him.

"..."

"..."

"..."

"..."

"...WHAT ARE YOU DOING HERE?!" Both of them exclaimed.

"This is my dorm!" Dipper explained.

"Really? Where is your evidence that this is your dorm?" Asked the black haired woman.

"Because it says so on my schedule, and this a two bedroom room!" Dipper points to identical queen sized bed across from the bed she was sitting on.

"...Crap." The woman cursed.

Dipper then looks at her eyes, and it was the same color as Headmaster Arkham's eyes.

"Hey...I don't know if you noticed, but you and Headmaster Arkham have the same colored eyes." Dipper stated.

Dipper then saw her eyes widen and she cocked her pistol.

"ARE YOU SUGGESTING SOMETHING?!" Her voice filled with anger.

Dipper didn't understand where this hatred was coming from, but her reaction from mentioning the Headmaster was strange indeed.

"No...I was just curious that's all..." Dipper lied.

The dark haired woman then slowly put her pistol down.

"Let me make this clear...I would have preferred having this dorm by myself, but since you are my dorm mate, I have no choice but to share...I am warning you though, touch any of my weapons, I'll kill you. You take a peek of my clothes or undergarments, I'll kill you. See me naked, I'll kill you. Piss me off in anyway possible, I'll kill you. And most importantly, touch my necklace, and I won't give you a quick death, I'll make sure to tear off all your body parts piece by piece, even your genitals. Then I'll cut off your head, take your genitals, shove them into your mouth, then use your head as a football, and finally use my rocket launcher to blow up your head...Understand?"

Dipper was surprised how serious she was, none of the less he just nods his head nonchalantly.

'That's it? I'll be honest, I was just exaggerating a bit with the whole genital things, but I will still kill if touches my necklace.' Thought the woman.

"You know, you still haven't given me your name." Dipper mentioned.

"Like I said earlier, you can call me whatever the hell you want." The woman said.

'I hope Mabel is having a better time than me.'

With Mabel Again...

"Of ALL the people in Gravity Falls, you had to be my roommate?!" Pacifica ranted.

"Glad to see you haven't changed in all." Mabel sarcastically spoke.

"Alright, I'm sorry, its just...You...Really?" Pacifica said.

"I know you and me haven't been friends...And were no longer enemies...Kind of..." Mabel said.

"Your probably wondering what I'm doing here right?" Mabel nods.

"You know thanks to that asshat Bill that my family is no longer rich right? Not that I've supported how my family gotten rich by the way, but money is still money. Well my family has been struggling for a while, had to take odd jobs because my parents aren't exactly the type to work."

Mabel looked at Pacifica in sympathy. "Oh, I'm sorry." Mabel said.

"It's cool, attending this university means that I don't have to stay with my family anymore. Believe me, they are worse now than what they were when they were rich." She turned herself away from Mabel.

Mabel saw that Pacifica was clenching her right arm.

"Pacifica...Did they..."

"...It was just my Dad...He was drunk one day...I couldn't take the abuse anymore and just ran away...Gotten myself an apartment, like I said I worked odd jobs to pay for rent...And here I am."

She was then hugged from behind by Mabel.

"I'm sorry you went through so much." Mabel said sincerely.

Pacifica smiled a little.

"Like I said Pines, it's cool. I'm here because I want a new life away from my broken family. Speaking of which, is Dipper here?"

"Yep. And I believe he's in room 444."

"...I'm so glad he's back...I really missed him." 'Dipper is here! Oh my god! How much has he changed?! He probably doesn't remember me! Don't be ridiculous of course that nerd remembers me!'

"Umm Pacifica...Your blushing." Pacifica eyes widen as she realized she was doing that.

"...Just put away your damn stuff!" Pacifica said, trying to change the subject.


It was now night time

The majority of Campus were now in bed.

The only ones who weren't sleeping were Mabel, Candy, Grenda, Pacifica, Dipper, and the dark haired woman.

The former three weren't in Mabel's dorm but her friends dorm.

"Ugh...It's the first day of the whole semester and I'm already sick of school!" Mabel groaned.

"It's not like the work the professors gave is hard Mabel." Candy said.

"I know...But the amount of work given they given us today should be illegal!" Mabel stated.

"Yeah! I say we gather all the homework, throw it into a pile, and burn it!" Grenda suggested.

"You know that's a perfect way to get kicked out of school right? The headmaster looked a no nonsense type of guy." Candy added.

"True...Say, how about we talk about relationships? Grenda let's start with you, how are things with you and Prince Darius?" Mabel said.

"Awesome. Our relationship has been strong. Sure we have our fights every now and then, but he supports me. In fact he paid for my tuition for the next four years. And he gave me a credit card so that I can spend whatever I want, and it has no credit limit."

Mabel looked shocked. "Damn. Your so lucky! My parents wouldn't even trust me with a debit card!" Mabel pouted.

She then turns to Candy.

"What about you Candy? You have a boyfriend?"

"No..It's just ever since high school, I've been focusing on class and extracurricular that I didn't even have time for relationships. Speaking of which Mabel, what about you?"

"Yeah...I don't have a boyfriend either. Truthfully, I've been trying to focus more on helping my brother find a girlfriend."

Both Candy and Grenda looked shocked.

"What's with those faces?!" Mabel questioned.

"It's just...We know how overzealous you are when it came to finding a guy, but to hear that you never sought a boyfriend is-"

"CRAZY!" Grenda finished.

Mabel smiles at them.

"I know...But I've realized that I've always screwed over Dipper when it came to finding the perfect boyfriend. And Weirdmageddon showed me how selfish I really was, so I figured that I'm no longer going to look for a boyfriend at the expense of Dipper." Mabel stated.

"Your serious?" Grenda asked.

"Dead serious." Mabel answered.

She then got up and stretched her feet.

"Anyway, I've got to use the restroom. I'll be back." Mabel then exited the room.

Suddenly, both Candy and Grenda were grabbed from behind. Before they could even process what happened. They sunk down to the floor like it was water.

Mabel busted the door down with a serious expression.

A few seconds earlier...

Mabel was looking for the restroom when she stopped.

She perked her ears when she jumped in the air as something burst out of the floor with long claws.

The monster had light blue fish scales for skin, shark teeth, its eyes had no pupils, its hair was green kelp colored. It's forehead had light similar to what lanternfish had, and his feet were webbed.

The demonic fish man roared before lunging in the air to Mabel.

Mabel however did a front flip and landing an axe kick to the fishman's head. She grabbed both its arms and without any effort, ripped them off! Black blood spurting out of its stumps.

The fishman howled in agony.

"Wow Mabel I've got to hand it to myself, I disarmed a fishman!" Mabel quipped.

The fishman looked beyond furious and lunged to Mabel.

Mabel used its arm to smack it in the leg, making it fall, before Mabel used its other arm to pierce its neck using the long claws just before it hit the ground. The fishman was now dead.

"I know of a mermaid much handsomer than you." Mabel said. Then her expression turned serious as she rushes to Candy and Grenda's dorm. She busted the door down but to her horror, the girls weren't there!

"Shit! I've got to find Dipper!"


Dipper was in his room, already doing homework. Meanwhile the heterochromia eyed woman was laying on her bed, staring into the ceiling.

Dipper then stopped writing and jumped off his bed with a serious expression.

The dark haired woman turned to Dipper.

"What are-"

"Something is here." Dipper interrupted her.

Dipper was looking around the room, he knew his instincts were warning him of something.

The woman then looked up and her eyes widen, demonic fishmen were diving down from the roof. Their claws aimed for Dipper.

The woman got up and was going to shout for Dipper to look up, but then something unexpected happen. In one instance, Dipper was staring at the door, when she blinked, Dipper was holding some type of scabbard and his eyes were closed. The scabbard is black, made of traditional lacquered wood, and features several metallic ornaments on its far end. She then saw Dipper unsheathe what appeared to be a katana. As soon as he did, the fishmen from earlier were cut into pieces like they were sushi. Their cut bodies hit the floor.

The dark haired woman was astonished to say the least.

'Unbelievable! I blinked for one second and he already cut them down like they were nothing!'

She then stared at Dipper and sweat.

'For him to do that...He must be exceptionally skilled as a swordsman!'

Dipper opened his eyes and turned to the woman.

"Demons have invaded this school." Dipper states.

Once again the woman was astonished, but for a different reason.

"...You know about demons?" She questioned.

"Yes, but questions can come later. Right now if my hunch is correct, there are demons targeting the humans in dorms. I've got to find Mabel."

"I see...In that case, I'm coming with you. Not because I can't handle things myself, but because you seem to know what your doing and not some idiot who's just waving a sword."

The woman then loaded up her weapons including what appeared to be a mix of a rocket launcher and an axe strapped to her back.

"...How did you pack all those weapons without getting attention from the school staff?" Dipper questioned.

"I have my ways...Now let's move. If you get caught in my crossfire, that's your own fault." The armed woman said as she ran out of the door, Dipper following suit.

Both of them turned the opposite direction of the hallway.

"So where's your sister?"

"She's two floors below us." Dipper answered.

"Let's take the stairs."

"Nah, I have a faster way."

Dipper pulled out his katana from his scabbard.

The katana had a diamond shape handling. There is a gold dragon styled menuki inserted underneath the handle. The hand guard has a gold and a deep navy blue shaped like an octagon with two trapezoidal halves, each with gold dot pattern patches and in a grove like motif with gold rings, inside of which are various circles in clusters of three, arranged in triangular patterns, and the gold fuller is also with a similar embossed pattern. The wave crest pattern featured is a tadpole head clove flower-styled hamon.

Dipper gestured for the armed woman to come closer. Which she did.

Dipper then spun around in a circle while holding his katana. What that did was cut a hole where they were standing. It caused them to fall down two floors. It also crushed a fishman. Two more fishmen rushed at them, but the woman pulled out two pistols and shot both of them in the head, killing them.

"Now if I remember correctly, Mabel's dorm number is 213, so we should-"

"AHH!"

Both of the turn to a person being chased down by the demonic fishmen.

Dipper then disappeared and reappeared behind the fishmen, then he unsheathed his katana and the fishmen were cut into pieces.

Dipper turned around to the person.

"You alright? Staying here isn't a good idea you should..."

"Dipper?"

Dipper's eyes widen as he recognized the person he just saved, it was Pacificia Northwest! And Pacificia recognized Dipper, who looked more handsome than when he was 13.

"...Pacifica?" Dipper stated.

"Wow...It is you. You changed a-a lot." Pacificia said. Meanwhile Dipper was trying to talk to Pacificia, but was having trouble with how attractive she is now.

"Oh...Well...You...Definitely...Changed too...I...Like your necklace." Dipper said.

"Oh...Thanks...It's my mom's actually..."

"That's cool...I still have Wendy's hat..."

"Dear god Dipper! Even in a life or death situation, you still can't talk to the ladies!" They turned to Mabel who had a sword in her hand. It is a massive longsword with a heavy double-edged blade, notched on both sides near the tip. The grip is plain, but the guard is skeletal, with a skull-design on each side leading to the rib cage from which the blade emerges; on one side of the blade, the skull is that of a human while the other uses a horned demon skull. Initially, the crossguard is folded in against the ribs.

They also noticed that there was fishmen heads on the blade like a shish kabob.

"There you are! So you know what's going?" Dipper said.

"Yeah, these demons are not only attacking the humans here, but are kidnapping them too. Those bastards took Candy and Grenda!" Mabel explained, which made Dipper gasp.

Mabel's eyes then locked to the dark haired woman.

"Wait! What's she doing here!" Mabel said while pointing to her.

"Huh, so your a demon slayer like your brother...Interesting." The dark haired woman said.

Mabel looked dumbfounded. "You know about demons too?!"

"Okay hold up! What's this about demons!?" Pacificia questioned.

"The question we should be asking is where these demons are coming from." Dipper said.

"Perhaps I can help you." A woman spoke. They all turn to a woman who was walking calmly to them.

She has a tan and a white, chin-length bob. Her outfit is a lacy, white one-piece with orange accents that exposes her chest and inner thighs. The chest area is held closed by a thick, orange chord zig-zagging across both sides. The one-piece has a loincloth and a long tail. She has white thigh-high, high-heeled boots. She also wears white, elbow-high gloves that fold at the top exposing an orange lining. It also has blue feathered shoulder pads.

Dipper blushed upon seeing her outfit.

"Who the hell are you?!" The dark hair woman questioned while aiming her pistols at her.

She just shook her head. "Relax, I am not an enemy. I'm your ally. I know where these demons are coming from. They are being summoned by a human being." She explained.

"Is that even possible? I know for fact that humans can't summon demons." Dipper stated.

"Not by themselves, but with magic. Humans are capable of using magic through unusual methods."

"She's right." They turn to the dark haired woman.

"How do you know that?" Mabel questioned. Now Mabel was familiar with the supernatural afterall, but she didn't know of any human who could weld magic.

For a moment, the dark haired woman looked down onto the floor.

"I just do...If what she's saying is true, than there's a scumbag who's using inhuman means to kill people...I hate demons and people like that."

"If you going to start, I recommend going outside." The white haired woman said.

"Alright, thanks...Ms..."

"Gloria, call me Gloria." She interrupted Dipper then smiled.

She then walked past the group.

"I'm expecting a lot from you two, descendants from Sparda." She whispered. But only Dipper and Mabel heard that and were both flabbergasted. As much as they wanted to question her, they had a more important mission.


"...Where...Where am I?" Candy groaned while waking up.

"The last thing I remember was us talking...Mabel went to the bathroom...And something...Grabbed us."

"Huh?!...WHAT?!...WHERE ARE WE?!" Grenda also woke up, but screaming. And the reason was because they were both chained to the roof of wherever the hell they were.

And it wasn't just them, more students were chained up as well.

Both girls saw someone who wasn't chained up. The man was sitting on a table, looking to be dissecting something.

What he was dissecting was a human head who's brain was exposed.

"I wonder...Is it possible to transfer the knowledge of a human being into the body of a demon?"

The scientist looked to be in his late 20s. He had black short spiky hair. Wore glasses that didn't show his eyes, wore a long lab suit, yellow gloves, brown pants, and brown shoes.

The man got up and turned to walk to Candy and Grenda.

"Ah...Glad to see my sacrifices are awake."

"SACRIFICES?!" Grenda screamed.

"Ah, I see this one is loud. Definitely killing her first." He spoke without changing his facial expression.

"W-Why are you doing this?!" Candy exclaimed.

"By what reason should I tell you why you are going to die? It defeats the purpose of a sacrifice." He then walks away from then and turns to another captured student.

He then pulled out a book and opened it. He then started chanting something inhuman.

Then the chains moved the captured student to the floor.

He walks up to the frightened student.

"PLEASE! LET ME GO! I DON'T WANT TO DIE!" He begs.

"Sorry...Sacrifices shouldn't beg." The scientist then chants something and from the book, black lines appeared and stabbed the student in the head, the heart, lungs, liver, and neck.

Both Candy and Grenda were horrified at what they saw.

The corpse fell down to the floor, the lines were removed, blood oozing from the floor, there was drain collecting all the blood into a tube to somewhere.

He then turns back to the girls.

"Now your next." The scientist did the chant again, the chains lowering Grenda to the floor.

"NO! STOP! DON'T KILL HER!" Candy shouted.

Grenda was fearing for her life.

"Don't worry, I'll make it quick, I always do..." He smiled sadistically.

Before the scientist could even make a chant, the roof rumbled.

"Huh?" He looked up and saw the roof break apart. Dipper, Mabel, Pacificia, and the dark haired woman fell to the lab.

Earlier...

The four were outside the campus.

More demonic fishmen were attacking them. Only Dipper, Mabel, and the dark haired woman were fighting. Pacificia was circled in the middle of the three because she can't fight.

Dipper was vertical cutting the necks of the fishmen who came close. Mabel was either swinging her sword or stabbing it to the fishmen. The dark haired woman was firing shots to kill the fishmen.

Then something strange happened. The rest of the fismen who weren't killed decided to literally sink into the ground and swim away. The latern lights were only seen over the ground.

"GUYS FOLLOW THEM!" Dipper commanded.

The four followed the remaining fishmen until they saw their lantern lights sink into the ground too.

"Jackpot." Dipper said.

Except for Mabel, Pacificia and the dark haired woman looked confused.

"What do you mean Jackpot, we're literally in the middle of nowhere!" Pacifica stated.

Dipper shook his head.

"No, I know because the way they were retreating. If they all decided to completely dive here then..."

"That's where Candy and Grenda are!" Mabel finished.

"Okay, but how are we suppose to enter the secret place." The dark haired woman said.

"Perhaps we can find some secret leverage or..."

"WE DON'T GOT TIME FOR THAT!" Mabel interrupted Pacifica.

"Uh oh...You might want to hold on." Dipper said to Pacifica as he grabbed her, making her blush.

Mabel jumped very high into the air, surprising those that weren't Dipper.

She then dives down and slammed to the ground hard so hard that cracks started forming.

Pacifica and the dark haired woman were speechless.

'She's this strong?!' Thought the dark haired woman.

'Holy crap! How much does she work out?!' Thought Pacificia.

The ground then falls under them as Pacificia screams for dear life.

Now...

The four were now in the lab. They were greeted to a horrifying sight.

They saw some students were already dead. Their corpses were in some type of box. There were some tables that had decapitated human heads. There were also jars that held brains. And the smell of blood was fresh in the air.

Pacificia looked about ready puke at seeing such awful things.

"Ah...More sacrifices..." The scientist said.

"MABEL!" Mabel turned to her friends who screamed for her.

"Guys! Don't worry! We'll get you out of here!"

The scientist then chuckles.

"I'm afraid not. You see those aren't just ordinary chains, they're coated by magic. Even a chainsaw can't break them." The scientist explained.

Dipper said nothing as he raised his katana and made two slashes. Now it looked like Dipper was just swinging at nothing. But then to the scientist's shock, the chains were cut! All the captured students fell to the ground, free.

"Candy, Grenda!" Mabel said as she hugged her friends.

"Thank god you both are still alive!" Mabel exclaimed happily.

"How did Dipper just do that?" Candy questioned.

"It's a long story, I promise we'll explain later. I need you both to get everyone out of here now!" Mabel points to a set of stairs at the end of the lab.

Both Mabel's friends nod and gathered all the remaining students who weren't killed and ran to the stairs.

The scientist frowned.

"You will not flee with my sacrifices." He opened his book and started chanting again.

The black arrows appeared from his book again, aimed for the students.

But a blue blur appeared and slashed the lines and went behind the scientist. Dipper turned around and before the scientist could register what happened, the lines were cut into pieces. And he also suffered a long gash across his chest, making him bleed.

The scientist turned to Dipper, stunted

'First he could down my enchanted chains, now he cut down my magic arrows, and even left me with a wound before I noticed! It's now clear that out of the four, he's the most dangerous.'

"I'm impressed. Your speed is extraordinarily and your swordsmanship is excellent...For a human." The scientist said.

Dipper spun his katana. "What if I were to tell you me and my twin sister aren't completely human."

This perked up the scientist, Pacificia, and especially the dark haired woman.

"Not completely human? What do you mean by that I...Oh...I see..."

The scientist then grins darkly.

"Then that means you and your sister are indeed special subjects. As for the other two humans..."

The scientist snapped his fingers and the very fishmen that retreated jumped out from the floor, ready to stab the human girls.

"...They can die." The scientist worded coldly.

Pacificia was then grabbed by the dark haired woman.

"Get behind me." She ordered as she shoved Pacificia out of the way.

The woman pulled out her gun and shot a fishmen in the head, killing it, she then jumped on its corpse, riding it like a surfboard. She then started spinning as she was shooting the fishmen. Leaving them holes with in their heads, chest, arms, and legs. She then did a backflip as she kicked the corpse she was riding on to the remaining fishmen. Then she took out her rocket launcher and fired at the demons, blowing them to pieces as she straps her rocket launcher back just before landing on the ground gracefully.

Pacificia was in awe at what she just watched. The black haired woman was just a human, yet she killed all those demons like they were nothing!

The scientist was rubbing his chin.

"Perhaps I underestimated raven hair, but blondie here is still the weakest link."

The scientist then started a chant and a single arrow that was very fast to Pacificia. The former rich woman turned around and saw that arrow was about to pierce her when.

SQUELCH

Pacificia's eyes were filled with terror when she saw Mabel with an arrow going through her chest. She was bleeding. Her body was spazzing.

"Huh, I expected more from you, but I guess you were a disappointment." The scientist said coldly.

The raven haired lady was speechless. Sure, she may have disliked Mabel upon meeting each other for the first time, but not even she wanted her to die like that. But what's really strange is Dipper not feeling sad, angry, or crying that his sister was killed like that.

"Mabel...You can stop pretending to play dead now." Dipper stated.

To everyone's surprise, except Dipper, Mabel raised her head with a cheeky smile.

"Come on Dipper! I wanted it to be more dramatic!" Mabel argued.

The dark haired woman was trying to make sense of this.

"There's only one way she could've survived that...Then that means...She and him aren't entirely human..." She clenched both of her fists.

"H-How aren't you dead?!" Pacifica screamed. Not that she wasn't happy Mabel wasn't dead, but this...Was something else.

Mabel motioned her to ask questions later as she grabbed the arrow and pulled it with all her might. Causing the scientist to be reeled to her while Mabel readied her fist. She then punched the scientist in the face, sending him flying into a wall while also removing the arrow lodged into her. The open wound was closing up for Mabel.

"Woah." Pacifica said.

The scientist coughed up blood upon impact and fell to the ground. He slowly got back up and saw that he was coughing up blood and his nose was bleeding.

"...You...And your brother...Are subjects I want..." He smiled.

"Alright! Cut the crap! Who are you?! What is all of this?! And why are you doing this?!" Dipper demanded.

"...Very well...You've heard of Frank Stein? The famous biologist of Gravity Falls? I'm his grandson, Faust Stein. As for what this place is? This is my lab where I run experiments and use sacrifices. Now, as for why I'm doing this...Is because I want to be better than my grandfather. He was known for his study in evolution. I was always in my grandfather's shadows! But I was given a wonderful opportunity! Every semester I would capture students, kill them so I can study their body parts, and finally, create specimens that go beyond evolution. Those demon fish you killed, they were actually cloned creatures made from the corpses of humans and sea life, specifically mermaids."

Mabel slowly turned her head to Faust.

"...The fuck you say? Mermaids?" Mabel uttered, no longer smiling.

"Yes. Believe or not, they were easier for me to capture than humans. I can never forget the screams they made when I was cutting them down piece to piece."

The scientist was making Mabel more angry.

"Tell me...Of all those mermaids you've killed...Did one of them have long hair, dark skin, and have a green fish tail?" Mabel questioned.

"Hmmm...I don't think I did...But then again I don't keep track of what every Mermaid look like before I kill them, but did you know that if burn them long enough, that if you eat a part of them, they taste like fish? Isn't that a kick-" Faust didn't finish as Mabel with fury in her eyes was inches from him, holding her sword as she stabbed him in the neck, but she wasn't done. She pulled out her sword and stabbed him four times in the chest, not before finally slicing his head off from his body.

Pacifica was surprised by the amount of brutality Mabel displayed, she was nothing like how she was 5 years ago.

Dipper appeared next to Mabel.

"Calm down Mabel, you know he was lying. He didn't kill him." Dipper said to calm down Mabel.

Mabel breathed heavily. "I know...But the way he was talking...He's a bastard that doesn't give a damn about lives!" Mabel exclaimed angrily.

"How interesting..." They all turned to Faust who looked uninjured.

They all turned to the corpse as silver liquid leaked from its neck, eyes, ears, and mouth until the corpse turned into a puddle of silver liquid. It then flew into Faust.

"That me was a clone. There are things I can do without my grimoire."

He then pointed a them while he mimicked a gun with his finger.

"I have to warn you...I'm using silver mercury, highly toxic on skin, but mine is more lethal." Faust warned as he shot out a mercury bullet with his finger.

Dipper went in front of the girls and did a vertical slash, cutting the bullet into two.

Faust then continued to fire bullets at Dipper.

Dipper then started spinning his katana like it was a pinwheel. The bullets were bouncing off his sword and landing on the ground. Dipper took three bullets and smack them back with his katana at Faust. Two of those bullets miss, one more grazed his right cheek.

"I'm guessing your immune to silver mercury." Dipper deduced.

"You would be correct. But you should know I still have some tricks up my sleeve. Oh Jaws!"

From the ground, another demon fishmen came out. Except it was a lot bigger then the demonic fishmen, the monster was about 9ft tall and muscular. It was more shark like as its skin was gray. It had two dorsal fins on its back. It had a shark face, and another one under it that was smaller. Four arms, and its hands also had teeth. Its feet were not only sharp, but webbed like its fingers. It had a saw mill at the end of its tail.

"This one is a pet project I've been working on for years. Now Jaws, make sure to finish your food before I've killed the swordsman here."

The demonic shark abomination nods.

Faust shoot out his silver mercury of his hand and went outside.

Dipper jumped out to follow him.

The shark abomination gave it a large roar.

In almost an instant, water shot out of all six of its mouthes.

Mabel threw her sword in the air as she grabbed Pacifica and the dark haired girl and moved out of the way from the blasts. When the water hit the floor, it left six large holes onto the floor.

"Holy shit! If the water hit us, we would've been torn apart!" Pacifica exclaimed.

Mabel then ran behind the shark demon as it swung its saw blade tail to Mabel, but Mabel easily avoided it by jumping and landing on its back. The shark felt Mabel on its back so it used its underarms to crush Mabel like she was a flea. Mabel at the last second Mabel moved out of the way from its hands. Running to its head and jumped. She then caught her falling sword and she dived down and stabbed her sword into its head.

The shark was roaring in agony. Mabel then removed her sword and dived down. The shark was now angry and used its other two arms to squash Mabel like she was a housefly. Before it could, Mabel started spinning like a ball as she was able to cut off the sharks hands. Mabel then jumped to the sharks' upper left arm and she once again dived while spinning to not only cut off the upper left arm, but its. lower left arm as well. Mabel lands to the ground gracefully while its arms fell down.

The shark roared out in pain and fury. The shark dived down into the ground like it was water. Making Mabel cautious.

The dark haired girl saw two dorsal fins peaking out of the ground. She grabbed her rocket launcher and fired at it. Only to reveal that it wasn't there.

Mabel also saw the two dorsal fins and she ran up and jumped before striking it between the dorsal fins. Only to hit ground.

"I don't get it...I know its fast...But why would it make us think it was there unless..." Mabel's eyes widen as she turns to Pacifica.

The shark demon jumped out to lunge at Pacifica. The blonde girl was frozen in fear.

Time slowed down, it looked like Pacifica was about to be killed. A split second later, a massive amount of blood was spilt, covering Pacifica.

"Are you alright Pacifica?"

Pacifica slowly turned to what appeared to be Mabel.

Her brown hair color changed to white. Her skin is reptile-looking appearance, including her arms and legs, her head seems to produce spiky edges, there are cracks on her chest, and she has a coat that is a pair of curled up semi-chiropteran wings with each divided into three segments. And her sclera was now orange and her eyes were red.

Pacifica looked behind her and saw the shark demon was split in half.

"Good thing I used my Devil Trigger otherwise you would've been shark food."

"..."

"Hey Pacifica? You alright? Do I have something on my face?" Mabel points to herself.

"...Your...Your..."

"A demon..." They turned to the dark haired weapon holder who had a dark expression on her face.

"Well yes, but as my brother would say, we're 25% demon, 75% human."

"I don't care!" The raven haired girl pointed her guns to Mabel.

"H-Hey! What are you doing?! Mabel just saved our lives!" Pacifica argued.

"Shut up! It doesn't matter! Her and her brother are demons! Demons are heartless bastards who don't care about innocent lives!"

Mabel crossed her arms.

"Did you not see me save Pacifica's ass from certain doom?! Cause if ya didn't, then your blind."

A bullet was shot as Mabel reared her head back. Surprisingly Pacifica.

Only for Mabel to move her head back and reveal the bullet the black haired weapon expert shot was stuck in her teeth. Mabel without issue bite it down and broke into pieces.

"Okay bitch, that was a freebie. But the next time you fire at me, your losing your fucking head." Mabel warned.

The dark haired girl was going to fire again, but then remembered how Mabel easily killed the shark abomination with ease. And something was telling her that Mabel was more dangerous in that demonic form than what she looked like earlier. As much as it pained her to admit, she didn't see any chance of killing Mabel.

She put away her pistols and turned around.

"You can do whatever the hell you want, just know that I'm not working with you demons." She stated coldly as she exits the lab.

Mabel turned back to normal.

"She's a total bitch, am I right?" Mabel said.

"Okay Pines...I know you and your brother are always wrapped around weird shit...So forgive if I'm being rude here but...WHAT THE ACTUAL FUCK IS GOING ON HERE?!" Pacifica roared out.

"Look, its best to ask Dipper, he knows more about this demon thing than I do." Mabel said.

"Speaking of which, do you think he'll be alright?"

"Sure. If anything, you should be worried about the scientist Dipper is facing." Mabel bragged.

With Dipper...

Faust was breathing heavily. So far, he was being dominated in the fight with Dipper. Looking at him, he was missing a left arm, several gashes on his torso, lacerations on his legs, and he had blood in his mouth, meanwhile Dipper remained unscathed.

"I need to know something...I know for a fact that isn't a regular katana...How does someone like you have a katana that unique." Faust said.

"My katana Yamato cuts through anything." Dipper states.

From behind him, a giant being made of silver appeared behind Dipper.

Dipper rolled his eyes as he sliced his blade upward. The silver giant was cut in half. It then turned into liquid and returned to Faust.

"It seems that I have no choice but to use it."

Faust opened his grimoire and went to a page that was empty.

He then wiped the blood from his mouth and smeared on the empty page.

Once again he started chanting.

Dipper decided enough was enough. He sheathed his katana then he pulled out the blade a little bit before sheathing again.

Suddenly a barrage of slashes circled Faust, cutting off his head, arms, and legs. He then dropped his grimoire, which was also slashed into pieces.

It then glowed ominously as the pieces of the grimoire entered Faust's chest. His whole body melted into silver mercury before it started to morph and transform. It started out as a gray blob that grew bigger and bigger until it eclipses the size of the shark abomination.

The blob grew a mouth filled with razor sharp teeth. Over its mouth a large eye appeared. And coming out of the blob was Faust up until his chest.

"Jesus christ...What have you done to yourself?" Dipper questioned.

"I transcended! I'm no longer human! I cut off all ties from humanity! And now I'm going to show all Gravity Falls what I can do!" Faust boasted.

"Sorry pal, Gravity Falls already suffered from multiple disasters before, I'm not letting you cause another one." Dipper states as he grabs his blade.

Faust summoned a bunch of tentacles to grab Dipper. But he simply disappeared as they stabbed the ground. Faust looked up to see Dipper in the air while he was upside down. He then aimed his hand at the tentacles and summoned what appeared to be blue swords as they rained down and struck the tentacles. Faust tried to reel them back, but was surprised that they were stuck.

As Dipper was falling down, the mouth shot out its long tongue to Dipper to stab him. Dipper then started spinning as he cut the tongue to pieces, not before jumping and stabbing the blob's eyes, causing the blob to reel in pain. Dipper then jumped and was in front of Faust.

"Die." Dipper states as he did a long horizontal slash that cut the blob into two. But to Dipper's surprise, the blob came back together, and all the damage Dipper did to it didn't matter because he started healing. Dipper was in shock that failed to notice the tentacles behind him as they went through his body. Blood oozing from Dipper.

Faust then laughs.

"You idiot...Sure you stopped me from retracting my tentacles, but you didn't notice that they were already underground when you stabbed them. And thanks to the blood spell in my grimoire, any attack you give me, will automatically be healed thanks to my beating heart. And that's not all, I pierced with silver mercury, so even if you can heal from my attack, the poison is already in your system."

He placed Dipper over the blob's mouth as its regenerated tongue loomed under Dipper.

"Before you kill me...I need to know something...How did you gain those powers?"

Faust smiled.

"Well...Normally I wouldn't tell people anything important before I kill them...But I'll make an exception for you! You see...5 years ago, I was a nobody...No one took me seriously...All I had was my name...But then, a man approached me, his name was Arkham!"

Dipper gasped. The headmaster of the university was behind creating someone like him.

"Thanks to him, I was able to use magic similar to what demons do! Then he gave me a task! Make sure to capture students so that I can kill them and take their blood! And I have been doing this for 5 years!"

Dipper glared at the man.

"You bastard...How can you enjoy something like that with a smile on your face?!" Dipper roared out.

"Because I can! Arkham saw my potential and helped me flourish! And if it means killing humans, mermaids, any creature I come across, than I'm willing to do whatever it takes for the people to know my name!" Faust boasted.

He retracted his tentacles as Dipper fell onto the blob's tongue, before it swallowed Dipper.

Faust waved at Dipper.

"Bye bye, if you see my grandpa, tell him I was better than him!"

"Now to see if Jaws killed those women, though its odd that he hasn't come to me yet. Oh well...If he was killed then I'll just kill the remaining women and-"

Faust was stopped as he felt something wasn't right. In fact, he was clutching himself. The blob was wringing in agony.

"No...That's impossible! There's no way he should be alive!" Then, a blue blur shot out of the blob.

"Never let your guard down."

Faust looked to see what appeared to be Dipper flying in front of him.

His hair was white, his appearance was reptilian and was like Mabel's transformation, except most of his body was blue, he had crest has a fin shape on top of his head. Also his neck gains a membrane that curves inwards, the spine merges with two dark-colored bones exposed at the top as well, his sheathe alters and attaches to his sleeve while becoming a clawed appendage, and his vest changes to a undercoat. And his feet are unchanged but darkened, he obtains a bright blue aura and his teeth are fangs that show. And his scleras are green and he has blue eyes.

"So you really are part demon...It won't matter I-HURGH!"

Faust puked up blood.

"But how..."

He then looks at Dipper blade and his eyes widen as he spots his heart onto the tip of his blade.

"You know...You shouldn't give out your weaknesses until your sure you've beaten the enemy...That's common sense." Lectured Dipper.

"I-Impossible! You shouldn't even be moving! The amount of mercury in your blood should've killed you!"

"Your right! It would've...If I was entirely human. My Devil Trigger not only makes me stronger, but it heals my body of anything, including mercury poison. And even without it, my body would've expelled the poison in the first place. But as for you...Your finished."

"W-Wait a minute! You don't need to kill me! Why don't you join me!? Together me and you will become gods! Arkham can make that happen!" Begged Faust as he raised his arms.

"...Your asking me to spare your life?...Tell me...How many lives have you ended for your pursuit of recognition?" Dipper asked in a cold tone.

"No..No! Y-You got it all wrong! I...Never wanted to do all of this! Arkham forced me! He forced me to kill all those people! Dissect those creatures! I'm...A victim!"

Dipper looked disgusted.

"Your so twisted, that you can't even lie. You do enjoy killing for the sake of it. It's true that demons exist, but there are those that don't have to be demons to be evil. Like you."

Dipper then removed Faust's heart and threw it at him.

"Make sure you crown all your achievements in hell."

Time then stopped as Faust was about to catch his heart as Dipper slashed at Faust with all his might at different directions. Then Dipper unsheathed Yamato as time returned to normal.

Faust's heart was cut into shreds. Then Faust's glasses were cut as they fell off his eyes. Revealing his blood shot eyes and the bags under his eyes.

Glass could be heard shattering as Faust in the blink of an eye was cut into pieces.

'I...Will...Be...Remembered.' Were his last thoughts before succumbing to darkness.

All the silver mercury were dissolved.

Dipper then transformed back to normal.

He ran to the hole Mabel made and jumped down.

"Hey guys." Dipper said.

"Dipper! Glad your okay, what happened to the Faust guy?" Pacifica asked.

"Oh...Let's just say he's everywhere if you catch my drift...He's dead in case your wondering." Dipper answered.

"Boo!" Mabel said.

"Now that your here. Can you please explain to me what the ever loving fuck is going on here?!" Pacifica demanded.

"Sure, but we need to figure out what Faust was doing." Dipper said.

The three turn and saw a metal door.

Mabel punched the door down, as the three walked into another room.

They saw machines that were the size of an average adult, looking like something they've seen in fictional movies to create clones.

"Guess that's how he was able to clone those demons." Dipper deduced. He then slashed the machines to make sure they could never be used again.

Mabel saw a box filled with corpses of animals and mythical creatures.

"That bastard...I hope he's rotting in hell." Mabel cursed.

"Um guys...That's a big tree!"

They turn to Pacifica and were startled by what looked to be a demonic tree. They were also startled by several tubes injected to the tree as blood was being siphoned to it.

The tree then glowed as something was growing from the branch. It looked be some type of fruit, but it was dripping blood from the bottom.

Mabel jumped off and grabbed the fruit.

"This...I can't make heads or tails of this...But I do know it happened because of human blood." Dipper said.

He then took out Yamato and slashed the air a few times and the tree was cut down. He then cut the tubes so that there would be no more blood being siphoned.

"I wish Rebellion could do something cooler than Yamato." Mabel pouted.

Pacifica noticed a notebook on a table and picked it up.

"Notes about the Qliphoth tree?" Pacifica read.

"Sounds important, lets get out of here." Mabel said.

"You guys still owe me an explanation!" Pacifica said.

Dipper grabbed Pacifica and they dashed out of there.


Arkham was reading a book.

"Hello Arkham."

The headmaster turned to Gloria. He closed the book he was reading.

"Ah Gloria. What business do you have with me?"

"Bad news I'm afraid, Faust's lab was discovered."

Arkham's expression didn't change, but Gloria could tell he was disappointed.

"I told that buffoon to be careful, where is he now?" Arkham questioned.

"Apparently his chunks are all over the grass." Gloria told him.

"...So he's dead?...No matter, as long as the Qlipoth tree still remains, we can salvage this."

"...Question...Can we salvage a demonic tree that has been turned to splinters?"

"...So what I'm hearing is not only was the lab discovered, Faust is dead, and the tree that I NEEDED for the Qlipoth fruit has been cut down?!" Arkham seethed.

"Pretty much."

"And who's responsible for this?"

"Dipper and Mabel Pines. The twins YOU sent their admissions to. The very twins at this school now." Gloria explained.

Arkham closed his eyes as he placed a hand over his head.

"I see...This is just a minor setback. They still don't know anything about me yet...Thank you for telling me this Gloria. Your dismissed."

"Okay...And are we going to tell Faust's younger brother the news?"

"It won't matter, he'll find out either way. But what's important is that the descendants of Sparda and my ungrateful daughter is here. Soon I'll be able to unseal Temen-ni-guru and I'll wield the power of Sparda and conquer everything." Arkham explained.

Gloria walked out of Arkham's office. She then glowed as she transformed.

She now has lengthy, blond hair, blue eyes, and a very fair complexion. Her clothing consists of black leather pants, high-heeled boots, a corset, double belts, a choker, and some kind of wrist accessory.

I'll make sure that the twins stop you before your dreams come to fruition you power hungry bastard.'


Dipper saw that the dark haired lady was no longer in his room, but there was a letter on her bed.

Hello Dipper, I now know you and your sister are demons. I don't know how you were able to fool everyone else...Even if you fooled the whole world, a demon is a demon. I know because...I'm hoping after today, that we never see each other again...But if you want to remember me, you can call me Lady.

Dipper read the letter and looked sad.

"Damn, what a shame, I was thinking we could be a team." Dipper said in disappointment.

"Screw her! She tried to shoot me!" Mabel argued.

Pacifica, Candy, and Grenda were also in Dipper's room.

"So...Can you finally tell us what's up with you too! Cause I'm positive both of you never turned into demons 5 years ago!" Pacifica said.

Both twins looked at each other and nods as their eyes turn to their friends.

"To start...Me and Mabel learned that were descendants of the legendary Dark Knight who rebelled against Mundus...Sparda." Dipper states.


Chapter End

Author's Notes: Whew! That was a good first chapter am I right? So yeah. Dipper has Yamato and Mabel has rebellion. And in case your wondering, this is an AU. So this story will start with the plot line of DMC 3. Except, one of the twins aren't trying to open the Underworld for more power. And I know Lady in this chapter wasn't exactly friendly with Dipper and Mabel, but remember, Lady in the beginning of DMC 3 didn't like Dante until her character development. And Dipper will have a harem. So far its Pacifica for obvious reasons, Candy, and Lady so far. I'm not pairing him with Mabel and Wendy because MabelXDipper would be weird and I know some ship them but I don't. And Dipper and Wendy are just friends, the show made that pretty clear. Anyway, that's it for the first chapter, until then, Scourge7 is out!
