The girl stood by the window.

"You know, Preston… this is your fault."

"Shut up!" He spat.

"Priscilla and Pacifica wouldn't have left you if-" She started.

"I said shut up!" Preston shouted.

"Whatever. Just know I'm never coming back here again."

"Wait! You were meant to help." He begged.

"I hadn't agreed to any type of contract, I said I'd look into your past and help only if you were worth it." The girl muttered, "Now I'll be taking my leave."

"No… I'll find you! I'll make you beg for mercy, to beg to work for me." He screamed.

"How could you? you don't even know my face… my skin … my name… all you know is a back silhouette."

With that, the girl jumped off the window ledge and disappeared into the inky black forest.

Chapter one - Monster girl

The following summer after Weirdmageddon

A boy and girl are have been sitting on a bus for eleven hours. The boy was slightly taller than the girl.

After constantly begging their parents and multiple phone calls, Mabel, Dipper and Waddles were on their way back to Gravity falls.

"I can't believe we're going back! Until were eighteen as well." Mabel squealed.

"Yeah, I'm really gonna miss mum and dad but this place is like a home to me as well." Dipper replied staring out the window.

A sign saying 'Welcome to Gravity Falls' blurred past the window.

"Anyone for Gravity Falls please get off." The bus driver called.

"Yay!" Mabel screamed jumping off the bus.

Dipper followed and the bus departed.

"Hey dudes." A voice called.

"Soos!" the twins yelled barreling into the older man.

"Hey kids!" Melody smiled.

"Hey!" Dipper said.

Then Mabel hugged her tightly.

"Let's get going, your Grunkles won't be here for the next few weeks though." Melody told them.

"That's okay, we need to get settled first." Dipper replied.

"Yeah and we still have the whole of summer with you guys!" Mabel exclaimed

"It's great you dudes were able to come back so soon." Soos said.

"Well, we're glad to be back!" Dipper grinned.

The next two days were used for settling in, Mabel's favourite moss spots were still there and Dipper traded his hat again with Wendy. Candy and Grenda came to visit along with Gideon and Marius who had stuck himself close behind his beloved. Mcgucket came to visit too, bringing a wacky machine with him. Pacifica also came.

"Hey guys!" She smiled.

"Pacifica! You should totally join my sleepover with Candy and Grenda." Mabel yelled.

"Yeah sure." laughing when she saw Dipper groan, "Hey! Hey! Let's go into the wood and find a monster!" Pacifica suggested.

Dipper raised a brow, "Why?"

"Umm… well, I never really went exploring with you guys and I felt kinda bad for Dipper… also, I'm really bored." she murmured.

"Good enough for me! Dipper! Get the cage!" Mabel shouted.

"Yeah, yeah." he laughed.

It'd been uneventful at home and Dipper had been craving for adventure.

"INTO THE WOODS WE GO!" Mabel screamed at the top of her lungs.

"Shut up Mabel!" Pacifica hissed but ended up laughing as Mabel continued her scream song.

"Mabel you might attract something that we don't want near us," Dipper called from behind them.

"That's right."

"Thank you, Pacifica." Dipper said.

"I didn't say anything," Pacifica replied slowly.

"You kids are loud… I like that. 'Specially the sweater girl."

"Thank you!" Mabel grinned.

"Hey mind showing yourself?" Dipper said slowly opening the cage.

"... sure, why not."

The trees above them rustled and a black mass dropped, it stood there in all it's glory before slipping and falling face first. Dipper screamed. It stood up.

"Hello… Pine tree?"

Before Dipper stood a girl taller than him, around Wendy's height. Her skin, which was mostly covered in black shiny scales apart from her stomach and space between her chest, was a smooth chocolate colour. She had a thick long tail which was also covered in black scales. On her head, she had black horns which were extremely sharp and her dark brown, fluffy hair reached her shoulders. She was pointing at the little pine tree on Dipper's hat.

"Aaaah! Demon!" Dipper yelled.

"Hey, that's rude! I'm a monster." she said with a confident look on face, "As for you… Shooting star?"

She walked up to Mabel placing a hand on her head, "Did you make that jumper? Cuz' it's adorable!" her eyes sparkled.

"Oh yes, I did!" Mabel replied already bonding with the monster.

"Hey leave Mabel alone," Dipper called.

"Oh, so your name is Mabel. It's very pretty."

"You know my name so what's your's?" Mabel asked ignoring Dipper's attempt to separate them.

"Ivy. Ivy Noir," she said proudly.

"Your name is so much prettier!" Mabel gasped

"Really? I don't think so." Ivy laughed softly.

"What are you?" Dipper asked.

"Me? I'm a dragon… monster… thing… I don't really know." She shrugged, "Oh your hair is very pretty. Pacifica? Right?"

"How'd you know my name?" Pacifica questioned.

"Word gets around." Ivy smiled

"Anyway we have to go," Dipper said.

"Oh, really? It's so lonely." Ivy said, plaiting Mabel's hair.

"Then come with us!" Mabel cried.

"Hmm… not too sure your bro likes me." She replied as she finished with Mabel's hair.

"Even so that's not the only problem." Dipper tried to point out.

"Oh but it is." Ivy snapped her fingers.

Her scales and horns dissolved and left a teen wearing black shoes and shorts, white tank top and blue hoodie. Her skin and hair were the same.

"Hullo!" She grinned.

"Woah, you're really pretty." Pacifica gasped.

"Thank you." she smiled.

"Fine whatever," Dipper growled and of they set.

'This is nice...' Ivy thought to herself, 'At least now I have people to talk to.'

She smiled looking to towards the three kids in front of her.

"Michael…" Ivy said.

Dipper turned around quickly, "What?"

"Ha, so that is your name, Dipper suits you much better." Ivy smiled.

"I didn't tell you-" Dipper started.

"I said word gets round, didn't I?" she grinned confidently, "Mabel, Pacifica go ahead real quick. I'm gonna talk with Dips here."

"Please don't call me that…" Dipper sighed.

"Why?" Ivy asked cheekily.

Mabel smiled and dragged Pacifica along with her.

"What do you want?" Dipper hissed.

"Nothing, in particular, I just felt as though you wanted answers."

Dipper stayed silent for a second, "Why are you here? We've come into this forest multiple times and never seen you once, the journals never mentioned you."

"Well, I saw you many times last year but neither you or Ford ever sensed my presence." She said.

"Then where did you com from?" Dipper asked.

"Hmm… well, you ain't gonna like this but Cipher made me -"

"What?! No, no, no! You need to get out of here." Dipper growled.

"And you need to listen. I was disowned." Ivy said.

"What, why?" Dipper calmed down.

"Well, when growing up with Bill, I read all of his library learnt and learnt many skills so he originally thought I was the perfect little monster but when I was five he found I had human compassion and therefore if they were innocent I wouldn't touch them so he deemed me trash, disowned me and cursed me with a human life span. Then I lived in the forest for the last eleven years."

"Fat chance," Dipper muttered.

"Fine, how about this," Ivy said sticking out her hand, it set alight with a back flame,"If I'm lying, I'll die. Deal?"

Dipper was once again silent then he took her hand and shook it firmly.

"Good. Now two deals have been set, I wasn't lying and I'll protect you and your loved ones with my life. Now let's get going before your sister starts thinking anything weird." She grinned widely, pushing Dipper's hat down.

"Why'd you put your life on the line for people you don't know?" Dipper asked.

"If feel bad for what Bill did even though I'm not connected to him anymore. Also, Mabel come out." Ivy laughed facing a bush.

"Dang it, you found me." Mabel sighed.

"We can trust you right?" Pacifica asked.

"With your lives." Ivy smiled.

After that, they started to go back to the Mystery Shack.

"Mabel you know you should keep your hair like that more often," Pacifica said.

"I know, right? I really like it thanks, Ivy!" Mabel hugged the waist of the older girl.

"You're welcome, kiddo."

'I'm really not alone anymore.'
