chapter one - traitor

"shitty hair, go get me my textbook from my room."

kirishima raised an eyebrow at the demand, "i'm not your personal maid."

katsuki rolled his eyes and shooed him off, "go on, i don't have all day! besides, you owe me for doing this shit for you guys." he grunted, gesturing to all the homework and notebooks sprawled out on the coffee table in the common rooms. mina, denki, and sero were all engrossed in reading the chapter katsuki had instructed them to read.

kirishima huffed before getting up and going to the elevator, ignoring the smirk sent his way from katsuki. he made it to katsuki dorm in a couple minutes and opened it. he sighed as he realized katsuki didn't even tell him where the textbook was! he didn't want to snoop or anything, but... was this the perfect opportunity? hell yeah! maybe he could find some gossip to tell mina too!

kirishima grinned and quickly closed the door behind him, feeling slightly guilty when he looked under katsukis bed for gossip purposes. he smirked as he found a notebook, was it a diary?! he hesitated before dragging it out from under the bed, feeling guilty once again before he remembered how katsuki pranked him that one time... and that other time... and that other other time...

"it's fine! it's totally manly to get him back!" kirishima tried to convince himself, sitting up and holding up the notebook. he tilted his head in confusion, it wasn't a diary. it had 'quirk analysis no. 19' written on the front of it in messy handwriting. "what?" he muttered, his eyebrows furrowing.

he slowly opened the notebook, his heart pounding out of his chest and his eyes widening with every page he skimmed through. it was a notebook full of pro heroes' quirks, weaknesses, and so many ideas on how to defeat them. some pages were filled out with villains as well... kirishima gulped as he looked through the pages, dread filling him as he realized how dark this notebook was. it went in depth about the quirks, but also had questions that were very weird and cryptic about situations that the pro heroes could go into.

"this is... so much information. how did bakugou get all of this? what if--" kirishima gulped and shut the notebook, hesitantly taking it. thousands of thoughts entered his brain. what if katsuki was the traitor? kirishima winced at that thought, because how could he even say that about his best friend? but the notebook... it was evidence.

"fucking finally, shitty hair." katsuki scoffed as the textbook he asked for 10 minutes about was set in front of him on the coffee table. when he didn't get a response, he glanced up at kirishima with an eyebrow raised in question. he was confused on why the red head looks so nervous all of a sudden. "what's up with you, hah?"

kirishima frantically waved his hands in front of him, "nothing! let's get to studying!" he blurted out quickly, taking his spot on the couch again.

katsuki shrugged it off, before shouting at denki to focus again.

later that night, kirishima stared the notebook in his dorm. he hoped and prayed katsuki wouldn't notice it was gone, and hesitantly got up from his bed and out of his dorm. he made his way to the teachers floor and knocked on aizawas door.

"kirishima? its late. this better be good." aizawa grumbled and opened the door wider for kirihsima to come into his room. he was suspicious, since kirishima had a worried and anxious look on his face. he knew his student well enough to know he wouldn't be here for nothing. "what is it?" he asked, sitting down on his couch.

kirishima sighed and pulled out the notebook, "uhm, i found this under bakugous bed. its... here, just look in it." he shoved it into aizawas hands.

aizawa sighed and looked in it, face neutral as he read through the pages and pages of detailed analysis, some of it was information he knew was confidential, knew that if it ever got out to the public it would be dangerous. how would katsuki have gotten all of this? this could mean...

"thank you, kirishima." aizawa put the notebook down next to him.

kirishima stood still and then chewed on his fingernail, "what will happen to bakugou? hes my best friend, i don't want to be the reason for anything to happen--!"

"kirishima." aizawa interrupted, "nothing is your fault. this is very, very valuable information. we have to act on it, because this is information only a traitor would know." he finally spoke the word. traitor.

kirishima frowned and nodded reluctantly. his heart was completely torn... because on one hand, katsuki was his best friend and he felt like he was betraying him by ratting him out. and on the other hand, if katsuki really was the traitor, he needed to tell someone for the safety of everyone in u.a.

"okay. thank you mr. aizawa."

"get some rest, kirishima."

"yeah..."
