Inspired by a Tododeku fic named "Me, red marker and freckled ghost" by Drowsytea on AO3... U should check it out!

---LEts gO!---

At day she was Momo Yaoyorozu, the daughter of a business man. But at night she was Momo, the friend of a ghost.

Momo thought she was going crazy at first. There was always flickering lights in her room and her phone had a hard time working. Sometimes she even could hear soft humming, it was slightly distorted. And her room was always cold, even in the summer.

At first she thought of telling her mother or father, but quickly decided against it. She knew that they would think that she was crazy, and do something against it.

Momo came to the conclusion that it was a ghost. She wasn't scared. No, she was slightly disturbed.

Someone, a dead person, was watching everything she did. Studying, changing, crying out off frustration when she couldn't create certain objects, sleeping and so many more things.

Momo surfed the web and in the library after things about ghosts. She only found nonsense that wouldn't work. 

She didn't give up, no she was very determined to talk with the ghost.

The ghost scared the living shit out off her when five books fell out off her bookshelf. The books landed with a page upwards, seemingly at random. But Momo being a smart person found the message in the books quick. The first letter on a page was bigger than the others and if you put them together making it a word. M-I-R-R-O-R

Momo quickly walked over to the mirror in her bathroom that was connected to her room.

sorry if i scared you... if u haven't already figured it out, I'm a ghost

It stood on her mirror in a dark purple marker. Momo's eyes widened.

"C-can you hear me? Or do I need to write on the mirror?" Momo asked, still staring awestruck at her mirror.

no I hear you... Momo right?

"Yeah! My name is Momo.. what's your name?" 

u can call me Kyoka! nice to meet you properly... so, how was your day?

The mirror was quickly filled up with sentences.

can you erase what's on the mirror so I can write more?

"I'll go get some from the cleaning supplies... I'll be right back Kyo" Momo said and quickly rushed out off her room.

She was ecstatic, finally she was not lonely anymore. She had a friend!

Kyoka listened to her problems and Momo read? that's what you can call it, she read Kyoka's rants about how she died. Kyoka had apparently died by a drunk driver.

"Hey Kyo... They are making us move into dorms at U.A... do you think.. do you think that you can come with me?" Momo asked leaning back against her pillows.

The usual purple marker and a sheet of paper was laid on her bed.

hmm, I have tried to go after you before and it didn't work... maybe it's an object making me not leave?

"That could be possible..."

we should try it!

"Right!" Momo said and got up from her bed.

"What do you think is making you unable to leave?" Momo asked Kyoka.

maybe one off your books? try leaving the room and I'll follow!

"Should I try a music book first? you did tell me that you were attached to music when you were living" Momo said and walked quickly over to her books.

yeah!

Momo picked up a piano book she had got from her mother a while ago and walked out off the room.

"Kyo you here" Momo whispered, waiting for the feeling of her shoulder getting dunked in ice-cold water. Nothing happened.

A while ago they had discovered that when Kyoka tried to touch Momo, she would feel like she was getting dunked in ice cold water. Like in the Harry Potter books... Maybe J.K.Rowling knew a ghost who did the same?

She waited some seconds. Kyoka didn't do anything, so she was probably still stuck in her bedroom.

They went through half off Momo's books. And then Kyoka came with an suggestion. 

wait a minute, your parents always buy you new stuff? so it can't be a new book!

"So a old book then?" Momo asked.

yup, try that!

Momo picked up a book that she had found in an second hand shop. It was not old per say, no it was fairly new. But it was well used. A fairy-tail book about a baby dragon out on adventures. 

"Kyo?" Momo whispered, holding the book and standing in the hallway.

A ice cold feeling was felt on her cheek and her eyes widened. Kyoka was there with her!

Momo quickly speed walked into her room and sat down by the sheet of paper.

"Kyoka! you are bound to this book! Isn't it awesome? Now you can see the outside world" Momo cheered. 

yes!!! I remember this book, it was my favorite when I was a kid

"That's so cute"

shut up

Momo felt her room become a little bit warmer, meaning that Kyoka was probably blushing.

"Awwww Kyo! You are blushing, aren't you?"

noooo, what gave u that idea

"You totally are!"

---time skip---

Momo's classmates didn't know about Kyoka. But when they found out that there was a ghost pranking their dorm, Momo imitatively turned to Kyoka. But the rest off the class thought that it was one off the Bakusquad and was always on guard.

Kyoka admitted that it was her, but she convinced Momo that she wouldn't tell anyone. Kyoka wrote that she wouldn't prank Momo so she was okay with it, if it didn't come in the way for their studies.

This dorm is fucking haunted

ZzZ: anyone up?

Brib: ...unfortunately

Mom: why are you all up?

ZzZ: oh hello mother

Mom: don't call me that

Birb: Dark shadow is loosing at cards against a ghost

Momo froze up, was this why she couldn't feel Kyoka's pressence?

Mom: Is there a old book about a dragon going on adventures in your room?

Birb: Yeah.. how did u know that?

Mom: ...I'll come get my ghost then

Mom deleted 8 chats

Momo wanted to know why Kyoka was in Tokoyami's dorm room. And how she could be there, the book was still in her room right?

The book was not there. Had Kyoka carried it with her to Tokoyami's room or had someone taken it and dragged it to his room?

Momo sighted and picked up her ghost communicating notebook and a purple marker. She quickly made her way to Tokoyami's room.

"Hi.. welcome in Yaoyorozu-san" Tokoyami said and opened the door to his room.

Momo nodded her head and walked into the dark room. Dark shadow was sitting on a chair? It looked really weird. Kyoka and Dark shadow was playing some kind off card games. Although Momo couldn't see Kyoka it was clear that the ghost was winning.

"Kyo... I'm glad that you are having fun and everything, but you are ruining Tokoyami-san's sleep schedule" Momo said leaning against the wall.

The floating cards was dropped on the table and soon the marker was writing on the paper.

i'm sorry Momo! I was just bored

"Idiot I thought that I had lost you" Momo whispered. 

sorry to break it to you but you are stuck with me

Momo snorted.

"Come on, we won't make Tokoyami-san's sleep schedule worse"

but dark shadow? he'll be bored and lonely!

"I'm sure he's fine Kyoka"

but Momooooooo

Momo sighted and took the book.

"I'll be going with Kyoka, We'll see you around" Momo said and headed out.

"Good bye Yaoyorozu-san"

Momo speed walked back to her room and sat down on her bed. One more person knew about Kyoka, she hoped that nobody else knew.

"We will talk more about this tomorrow" Momo said and went to sleep.

Unknowing to her, Kyoka was sneaking her book into Momo's schoolbag, along with her marker of course. 

---time skip---

The class was as normal as ever. Dozing off during their English class with Present Mic. If Kyoka was here she would probably freak out since he was her favorite hero. Momo smiled softly at the thought. 

hey ;)

Her own pencil had written that. Wait a minute, Kyoka?

KYOKA!? Why are you here!?.. did you pack your book in my school bag?

yes! great guessing Mo!

They heard airy sounding laughing. It was Kyoka. 

Mic-sensei stopped talking, eyes widening. The class started to look around.

Momo and Tokoyami made eye contact.

Well this was bad.

I swear to god Kyoka

I was boredddddddddd- oooo, I should write on the board!

no don't do that!

There was no response. Mic-sensei's chalk started to float and everyone was freaking out.

hi! I'm a ghost.. boo! XD 
Anyways, nice 2 meet ya-
pls don't call the exorcist!

Momo face palmed.

Mo! Stop face palming, i'm just meeting ur friends :(

Her classmates and Sensei looked over at her.

"Kyoka.. can you stop? you are kind off making them freak out"

Sorry bae!

"Stop calling me that!"

never ;)

Momo sighted, this would take a long time to explain.

---*insert dramatic "the end" here*---

ZzZ=Shinsou
