Hello everyone! I'm DarkNutDestroyer and here's a new fanfiction! Always wanted to do it, but I didn't have a good idea to make it unique. I won't bore you with my incessant rambling so… let the story begin!

The Blood Runs Deep Into the Ground

"He who fights with monsters should look to it that he does not become a monster. Because when you gaze long into an abyss… the abyss also gazes at you."

-Friedrich Nietzsche

-X-

Naruto was unsure of what he was doing here. He was currently stuck in a bus with a creepy guy as a driver going to a supposedly "fancy" school that he'd never seen. He had a giant scroll containing all his possessions, his necklace that his God-mother gave him and his trusty old headband attached to his belt.

His current attire was consisting of orange and black concealing jackets and gloves, as well as pants and heavy-duty boots. However, his most unique possessions were a metal gauntlet that he wore on his right arm and a headband that hid his left eye. Along with them are several silver trinkets and amulets attached on multiple places of his clothes.

He wasn't sure how he came in this realm. When was about to seal Kaguya once and for all with his teammates, she tried to use her teleportation powers to send them all in a parallel dimension where they'd be stuck forever. However, Naruto was the only one touched by it before losing consciousness. He had then woken up in the multiverse.

It… was a queer place. It was a long white corridor and its walls were covered with doors of all shapes and sizes. He had simply opened one of them when he was sucked in it and ended up in this place. All his attempts to return home were fruitless and he had put the plan on hold.

He had explored the world, slowly gaining knowledge and experience and collecting powerful artifacts. He had also learned of the existence of monsters, or Youkai if you preferred. He had been marveled by the numerous species that inhabited this planet. They had hid their existence from humans and lived reclusively in isolated communities.

He had also practiced his fuinjutsu. Mastering it to a level that surpassed her mother and Jiraya. He had used it to create the impossible. He created a Kekkai Genkai. By engraving specific seals in his eye, he could use his eye to perform incredible feats. By infusing chakra in it, he could see attacks coming at him in slow motion, throw small-scale jutsus, create illusions, etc. Its only limitation was your imagination. It could also drag the consciousness of people into his mindscape. However, to avoid attracting attention to his eye, he had hid it with a bandana.

He had learned with amusement that they was also a Kyuubi in this realm. Regrettably, the Kurama sealed inside of him had stayed in the Elemental Nations. The Tailed Beasts were the pillars on which his old dimension resided on. Without a Tailed Beast, the Shinobi world would've collapsed on itself very quickly. Luckily, Kurama had given him a significant portion of his chakra before he left, saying that it was a gift for their friendship and that anyway, he could regenerate it with time.

He had finally settled down in Japan because of its similarities with his old world. He had bought an apartment with the money he acquired by publishing the books of his God-father and settled down. However, his peaceful life quickly ended when he got attacked by a gang of lizard man. They weren't really a threat to him. A rasengan to their faces quickly knocked them down. The real problem was that he attracted the attention of the Headmaster of the school where he was currently heading. He had convinced him to come to his school by saying that lizard man really extremely stubborn and would eventually come back to him for revenge. One day, his fights would attract attention and make him blow his cover. The Headmaster promised him that his school was protected by a powerful barrier and that he would safe in it. In exchange, Naruto was to protect the school from interior threats. Naruto accepted the offer, considering it to be the best alternative.

He looked at the gauntlet on his arm. It was a master piece. Each piece was beautifully crafted and aligned each other perfectly. He wasn't bothered by it and sometimes, he forgets that it's even there. It's most peculiar trait was the fist-sized gem incrusted in it. It was a magnificent amber jewel that shined of a soft light. It also pulsated like it was breathing. He had initially found it in an ancient temple in Germany. The reason why he stole it was because it had an interesting power of sealing immaterial beings.

Since the deity it originally sealed was long since dead, he now used it for another purpose, namely sealing Black Zetsu.

Yep. The will of Kaguya had been dragged with him. When he came here, the black goo spent his days crying in his corner of the loss of his mother. Naruto had left him alone with his mourning but after enduring his incessant cries for three weeks, he finally snapped. He had been dangerously close to simply kill him but he didn't want to separate himself from his only link to the Elemental Nations. So he trapped him a glass bottle. However, it still shook around and screamed. After finding the gauntlet, he trapped Zetsu inside instead. He was now much more silent now since it constantly drained him of his power.

Naruto then tapped the gem. "You still here, big guy?"

A black mist then gathered inside the gem and a small orb with a mouth appeared. It grinned at him and flipped him off. Naruto then grabbed the gauntlet and shook it around.

"Take that! Hahahaha! Who's the boss now, you little shit!"

The driver looked at him, shrugged his shoulders and went back to driving. He had wanted to warn him of Youkai Academy but after his display, he was actually concerned of the students' sanity.

-X-

Naruto was jolted awake as the bus stopped. Opening his eyes, he groggily stood up and, seeing that they had arrived to the school, attached his scroll to his back and walked out the bus.

"Goodbye, bus driver-san. You should get sunglasses; you'd look much cooler." Naruto said before stepping out of the vehicle.

The mysterious man chuckled. "A dimension traveler, huh? You really are interesting, Naruto Uzumaki Namikaze."

Meanwhile

Naruto was now walking down a dirt road towards the school. It was a pretty depressing sight. Dead trees, tombstones, skulls…and a sea of blood? Seriously?

However, the trees were still alive underneath. Naruto looked around for anyone before activating Sage Mode. His irises became horizontal slits and orange pigmentation appeared around his eyes. He then used his power to sense his surroundings. He saw that Youkai Academy was in fact inside a parallel dimension surrounded by a powerful barrier. He sensed several powerful monsters. One of them was currently heading… right at him?

"Coming through!"

Snapping his eyes open and ending the sage mode, he jumped to the side as a pink haired girl riding a bicycle appeared from between the trees. Seeing that she was heading a tree, he extended an arm, caught her by the collar and pulled her from the vehicle. The bicycle then crashed onto the tree and dropped on the soil.

He winced as his arm was scratched from a sharp metal part of the bicycle and some blood trickled from the wound.

"Are you alright?" Naruto observed the girl. She was a total hottie. She had long smooth pink hair and emerald eyes. Her skin was creamy and pale, which enhanced her natural beauty. She was wearing the school's uniform and a collar on her neck on which a Rosario was attached. The strong presence he sensed seemed to be coming from the scarlet gem incrusted in it.

"I'm fine! Thank you!" Moka bowed to him repeatedly as Naruto blushed and scratched the back of his head. Naruto then saw her eyes cloud from desire and her mouth come dangerously close to his face. "Is she going to kiss me?" he thought.

Sweat started to roll on his brow. He closed his eyes from anticipation…and felt her bit him in the neck. Snapping his eyes open, he saw that the cute girl was currently drinking his blood. However, it didn't really bother him. The chakra that Kyuubi left him still gave him access to extremely quick regeneration. So, as the young girl was greedily drinking his blood, he could still regenerate it at the same rate.

Finally, after a few minutes, the girl stopped and wiped her mouth. When she realized what she was doing, she blushed heavily and hid her face in her hands.

'Cute', he thought.

"Well, looks like you're a vampire? Guess I really shouldn't be surprised." he said while snapping his neck back in place. She really had a strong grip!

"You-You're not afraid of me?" Moka frightfully said. She had never had a friend and she hoped this peculiar person wouldn't reject her.

"Of course not! You seem like a nice girl and that's all that matters to me!" he said. Hell! One time, he befriended a red-headed psychopath that tried to kill him numerous time!. A vampire was nothing in comparison!

"Would you be my friend?" Moka hopefully asked. She never had a friend. All the students in her previous school rejected her for her difference, which caused her to hate humans.

"I don't see why not! Okay! Starting today, you are one of my precious people! Let's start presentations! My name is Naruto Uzumaki but just call me Naruto!"

"Well, my name is Moka Akashiya. If I have to call you Naruto, call me Moka!" Moka presented herself. She was extremely happy to have a friend so early!

Naruto then grinned before hefting Moka's bike on his shoulder. "Okay! Let's go to school!"

"You don't have to do it!" Moka pleaded.

"Nonsense! What man would I be if I left a girl dirty her hands instead of doing it myself!" Naruto had actually gained manners after several beatings from Sakura. He couldn't say that she wasn't right. The way he ate ramen really was horrifying.

"O-Okay!" Moka blushed before asking him: "Wait, why aren't you wearing the uniform?"

Naruto visibly tensed and slowly looked at her. The atmosphere then became much tenser. Shadows covered the blonde and his eyes shinned of a murderous light. "WE WILL NOT TALK ABOUT THAT ABOMINATION."

The oppressive atmosphere was then lifted and Naruto's face returned to its usual jovial one. He then went to walk towards the school. Moka quickly ran after him, already doubting the sanity of her newfound friend.

-X-

After a brief walk, they arrived at the outskirts of the school. The school was ugly to say the least. Instead of being a modern construction fit for the education of its students. It instead looked like a Victorian manor that just screamed OLD!

After giving her back her slightly damaged bike back, they separated before going inside but they promised themselves to meet again. Naruto quickly found out that he stood out from the crowd because of his clothes and attracted much attention.

He then unsealed from his scroll Hades' helmet. Funny story, one time he managed to find himself in Hell and met the infamous Death God Hades. He had convinced him to play a game of poker in exchange of letting him go. After losing the game, Hades had challenged him to another one. Naruto, thanks to his devil luck, won again and acquired his adversary's helmet. Infuriated, the God had banished him from Hell. Hades didn't actually care for the helmet but his pride would be forever broken.

Naruto put it on to turn invisible. He could've also use the Cape of Invisibility but he had promised Harry that he wouldn't stain it.

Naruto then used his new found invisibility to walk towards the Headmaster's office. When he arrived in front of the doors, he kicked them open and took out his helmet before sealing it away.

"Well, it seems that you appreciated the uniform I sent you!" he said, chuckling.

"Ha ha. You're hilarious! It was so ugly I burned it the moment I saw it. I think you could make three different "Yo Mama" jokes about how ugly it was. Now let's cut the crap and talk business." Naruto said while taking a serious tone which made the atmosphere in the room tenser. "You said that there were 'interior threats', what do you mean?"

The Priest sighed before telling the blonde about the school's problems. Apparently, monsters didn't have anything to do whatsoever except trying to kill humans or creating an evil plan to destroy the individual/school/world. Like, come on! Don't they have anything else to do?

*sigh* The burden of being a bad ass mother fucker truly was heavy. Oh well, at least he could kick ass and be sexy as hell while doing so.

"Well, I'll see what I can do. While I do that, you'll predictably be sitting in this office speaking to yourself at key-point of the plot so that the readers wouldn't forget about you." Naruto said while standing up from his seat. "Ah! Almost forgot! Here's a gift."

He then threw at him an orange book. "It's the Limited Edition Platinum Icha Icha Monster Girl along with colored illustrated images and an eroge version. Have fun."

Naruto then closed the door behind him, already hearing the Headmaster taking out a box of tissues.

-X-

Naruto was now walking around the school, trying to find his classroom. He was surprised by how modern the interior looked, contrasting deeply with the exterior.

He was holding in his hand a map and was trying to find his way. The corridors were empty since he missed the Opening Ceremony and all the students have gone to their classes. He then heard someone running behind him. When he turned back, he saw Moka running towards him. "Hi Moka! Are you lost too?"

Moka blushed from embarrassment. "Y-Yes. What class are you going to?" She asked.

"Let me see… My class is 163." he said, remembering the number he was given by the Headmaster.

"Great! We have the same class!" She was very happy that they'll be in the same class as she was nervous for being alone. However, with Naruto with her, all her fears evaporated.

After that, they searched together for the class and finally found it. They knocked on the door and heard the teacher say "You may enter."

When they came in class, a chorus of exclamations came from the assembly of students.

"She's so hot!"

"Her hair is so pretty!"

"Screw the hair! Look at that ass!" Naruto memorized the guy's face, creating mentally a note to prank him later.

However, his thoughts were interrupted by other cat calls. However, those weren't directed towards Moka, but to him!

"He's so handsome!"

"Those whiskers are so cute!"

"He's so tall and muscular! I wouldn't mind waking with him sleeping next to me!"

Naruto blushed. Not being used to girls being actually interested in him. He then quickly bowed to the teacher and excused himself with Moka for their tardiness.

"Well, you can go sit there." The teacher said while pointing at two vacant adjacent seats. They went there and made themselves comfortable. The other students' attention was then attracted to the teacher when she loudly exclaimed "Hello everyone and welcome to Youkai Academy! I am your home room teacher Shizuka Nekotome. I think you already know this… but this is a school built for the sake of MONSTERS to attend!"

The teacher then started explaining about the coexistence between humans and monsters. Naruto was very interested. He respected those who installed this system but disapproved how it came to. Separating the two races will only stop the problem temporarily. Being forced to go into hiding will humiliate the Youkai people and it was certain that some pricks will try to kill all of the humans.

Naruto was still uncertain of what to do. He was in no way interested to fight overpowered monsters to save the world. He was already busy with his "Going Home" business. However… he couldn't simply abandon this world like that.

The blonde was then drawn from his musings when he heard a student speak up.

"Hey teacher, would it not be better for us to simply eat up those puny humans." he said. "And in the case of beautiful girls, better to molest them."

Ah, the asshole. Also known as the prick. He had learned his lesson back at the academy. It was like a universal rule: there's always a douchebag in a class with the main character in it.

This particularly one pissed him off to no end. It was that kind of behavior that contributes to the hate between humans and monsters. He reminded him in some way of Sasuke. The both of them though that their heritage gave them credit and made them superior to others. Even his opinion was shit. Monsters are naturally stronger than humans. However, humans were extremely resourceful and numerous. If monsters revealed themselves to the world, they'd be massacred by the human forces.

"Incidentally, here at Youkai Academy, the teachers and students are all monsters, there are no genuine monsters here!" The teacher said. "If one were to be revealed as a human, he'd be forced to bring DEATH on them or something."

"Tch. Even if I screamed on the roof to everyone that I was a human, I severally doubt they'd be able to merely scratch me." Naruto thought.

Finally, the bell rang and it was the end of the period. Since it was their first day in the school, students had the day off to explore the school and its surroundings. Moka dragged Naruto outside, earning themselves glares from jealous students, and went to explore the school.

However, they were interrupted in their search by a blonde student. It was the same asshole with the carnivorous attitude towards humans. He was wearing a smug look and looked at Moka with lust and Naruto with disdain. "You are called Moka Akashiya are you not? I am your classmate Saizou Komiya! Salutations!"

Naruto already wanted to go Itachi on him.

"By the way, why is a beautiful lady such as you associating with a guy like this?"

Saizou then went to grab Naruto by the collar. However, it wasn't the blonde that he lifted up in the air but… a puppet?

It was a simple puppet made of patchwork and buttons as eyes but something made it particularly creepy. It was holding in his hands a small knife and its mouth was stretched into a toothy smile.

The puppet then JUMPED on his face and started to stab his face repeatedly.

"AAAAAAHHHHHHHHHHH! Get it off! Get it off!"

Naruto then used the distraction created by his puppet to escape with Moka. Just before they roundedthe corner, he didn't forget to flip Saizou off and throw a kunai at his nuts because fuck that guy!

While they were running, Moka blushed from the contact of their hands.

Then finally stopped their running at an empty classroom. "Moka, are you allright?"

"I'm fine! Thank you Naruto for standing up for me!" Moka said. "It was the first time someone protected me."

"It was nothing. I told you I'd protect you, didn't I? You're my friend, Moka, and I'll always be with you!"

Moka smiled, feeling touched by Naruto's thoughtfulness. "Thank you for your kind words! Now let's forget about all this and go have fun visiting the Academy!"

Naruto shook his head, never stopping smiling and ran to catch up the bubbly pink haired girl.

The next few hours were the happiest of Naruto's life. Spending time with Moka had made him completely forget all about his problems. They had explored the school, found out some secret passages, played some pranks and generally had a good time. However, all good things had to end and the sun had already started to set. Naruto hadn't seen the time pass by and they had to go back to the dorm.

The school dorm was creepy. Like the school, it had a scary atmosphere and Naruto greatly suspected that someone died in there and its ghost was haunting it. Naruto shuddered. He still had his fear of ghosts. He made a note to visit the graveyard with his clones and salt and burn all the bones.

Turning towards Moka, he expected her to be as creeped out as him but face faulted when he realized she was admiring it and praising it of its "dignity" and "character".

"How can you call this architectural monstrosity as beautiful?"He grumbled in the dirt.

"You don't like it, Naruto? Even though you're a monster?" Naruto started to sweat. "Speaking of which, what monster are you?"

"Um… Well I'm uh…" Naruto stuttered.

"Oh! I forgot! Revealing our true forms is against school rules, isn't it? Sorry for having asked that question!" Moka said while rubbing the back of her head.

"Uhhh…" Naruto said, trying to find a distraction. "Oh, speaking of which, I can't really see you as anything except a normal human Moka. Are you really a vampire?"

"Well, you see…" she said. "Now I look pretty normal but when I remove my rosary, I become an evil and scary vampire."

Moka then started to explain the sealing power of rosaries. Naruto was very curious since it greatly remembered him of his seal. "You see, vampires are very powerful and considered superior even amongst monsters. I actually went to a human school up through middle school and my power made them fear me because of their basic instincts. I thought that by sealing my power, people would finally accept me but I was proven wrong when they started spreading rumors about me. I've been so lonely and when you accepted me as your friend so easily, it made me extremely happy. I'm also happy that you're a monster since I hate humans for what they did to me."

THAT made Naruto flinch. Moka had suffered the same hardships of life that he did. Being rejected by your peers for your difference was a terrible fate and it had affected his childhood greatly. He knew that the only cure for loneliness was love to fill the gap in the person's heart. Naruto vowed himself to always remain with Moka.

Moka's comment about her hate of humans was bothersome but since he DID have some demon power flowing through his veins, he couldn't really call himself a human anymore.

"Oh, but even if my power is sealed, I still crave for blood it's…" She then jumped on him. "…my weakness."

She then went to drink his blood… again.

-X-

Naruto sighed before dropping his bag and scroll on his bed. Moka was quite a girl. Well, at least she didn't hit him all the time like Sakura. He chuckled, thinking of his old teammate. He then went to the kitchen to eat something. And by something, I mean ramen. At least he stopped eating it everyday and actually ate decent meals.

After finishing his meal, he removed his gauntlet, putting it on a table. The problem with it was that if it didn't have a contact with a human body, it'd simply let the power of the trapped entity into the air without limitation, slowly weakening it until it died. It was meant as a measure to prevent the entity from killing the possessor. That was how the previous deity trapped inside died. It killed the priest that wore the gauntlet, dooming it to die since the gauntlet wouldn't accept anybody else to wear it.

At least he could remove it each night.

He then heard a knock on the door. He curiously headed towards it and opened it. He looked around, seeing no one. He felt a tap on his leg and looked below. It was the puppet that he had sent to assault Saizou. It was waving at him, his body was covered in blood but it still smiled at him.

Grinning, Naruto picked him up and brought it to his apartment, closing the door behind him. The puppet ran to the scroll and waved goodbye at him before sealing itself in it. The puppet was in fact a gift given to him by a blonde immortal vampire he had met in a campus somewhere in Japan. In return, he had removed the barrier imprisoning her.

He was sleepy but still had to do something. He removed his bandana and revealed his eye. From the eye then came out hundreds of seals that covered the entirety of the room's wall. The seals shinned brightly of a blue light before fading and disappearing.

Smiling, Naruto then went to his bed and fell asleep.

Chapter end!

Phew! Finally finished! I've always wanted to do this crossover but never got the motivation to do it. As you see, Kurama is gone and got replaced by Black Zetsu. I had always liked that character and though that there wasn't enough crossovers with him in it! Yes, Zetsu will help Naruto in future chapters since the both of them have the same goal: returning to the Elemental Nations. Naruto has lost his ability of using Kurama's power but still kept his other abilities. He had also collected quite a few artifacts while travelling the world. There will be minor crossovers later on. Also, Naruto had also created a bloodline by using seals. It is still incomplete and unstable though, which is why Naruto keeps it hidden with a bandana. Now, we'll see each other next time! Bye!

Love it? Hate it? Please review!
