A/N: The traitor has finally been revealed...
-Flashback-
Mikoto: Hey...Izuku...
Deku: Yes?
Mikoto: I'm sorry on behalf of my idiot classmates declaring war on yours. I try to tell them that you guys weren't total snobs but they wouldn't listen.
Deku: O-Oh that's okay Miichan. I'm sure they didn't mean it...I mean think about it. This is all for the Sports Festival. They just to prove themselves to be great heroes. Everyone here does.
Mikoto: ...Alright...Also. Izuku! I been meaning to ask you. Could you lead me some of your notes! I was hoping it could help my class improve on our skills!
Deku: O-Of course!
Mikoto: And don't worry buddy! It's not cheating! It's studying.
Deku: I-I know that!
Izuku then hand him one of his hero analysis journals. Mikoto read through a few pages and noticed himself in it.
Mikoto: (Wow...He memorised everything...Wait what is this...OMG That's it! This could help!)
Mikoto made a smile and hugged the smaller teen causing a small squeak to come out of Izuku.
Mikoto: Thanks Buddy! With this. I can study and help my classmates focus on their quirks and skills.
Deku: Y-You're welcome! Anything to help.
While the two have their conversations, Yin was watching from afar...
Yin:..........
-Later-
Mikoto: What the....?
Sylvia: What is it Mikoto?
Mikoto: Where did the Journal Analysis Go...?
Sylvia: The what?
Mikoto: The one that Izuku gave me before the Sports Festival. I was going to give it back to him after...but now it was gone.
Haru: W-Where was the last time you saw it?
Mikoto looks at his two friends and begin to the last place he put it was in his inside his desk.
But now it was gone...
Mikoto: Or maybe I misplaced it...
Sylvia raised an eyebrow.
Sylvia: Maybe someone took it.
Haru: Would...Someone in our class do that?
Mikoto: No...I don't think so...Oh Man...Now I feel guilty...How am I gonna explain to this to Izuku...?
Little did they know, Yin had put the analysis book inside one of his black hoodies before taking off.
-later-
Deku: Miichan...? What's wrong...?
Mikoto: H-Hey Izuku...I'm sorry...I think I may have lost your journal...
Deku: It's okay Miichan. I got a ton for them...
Mikoto: Oh...Right...I forgot you had a lot of them...but still...you work very hard on these journals...I just can't believe I lost it...
Deku: How about we look for it together.
Mikoto: Okay!
.....They never found it.
Yin:.......I'm sorry Class Rep...
-End Flashback-
Yin:...And after that...I gave the information to the villains....
All the U.A teachers present in the faculty couldn't believe what they heard.
They been looking for the traitor for months...
For those that don't recall; It's basically a given at this point that there is a traitor somewhere within the UA. Back then like Present Mic said, this traitor could be a student, teacher, or some other kind of employee within UA. The League of Villains has simply had too much access to UA information for there not to be a traitor.
But now...it was all revealed right her win front of them.
Yin Hamada...was the traitor they were looking for...
One of the most quietest students in Class 1-C.
They weren't kidding when they say it's the quiet ones you gotta look out for...
Midnight: Oh sweetie...Why did you do it?
Yin:......
Present Mic: Little Listener. Please tell us.
Geysis: Don't you understand what you did was wrong. A confession like that has you walking on thin ice.
Yin: I know...
Yin looked really guilty. Most of the teachers could see the look of fear in his eyes.
He's scared. It was written all over his face.
Scared of the punishment.
Scared that he has to face from the consequences of his actions.
Scared of everyone judging him.
Yin: H-How much trouble am I in?
Aizawa: We...will get to that later. Just tell us why you did it...
Snipe: And don't give any half-ass info. Just tell the truth.
Yin: ..... It's because of my Dad.
Ectoplasm:.....(I knew it.)
Aizawa: What did your father do...?
Yin decided to come clean.
-Flashback-
Yin was all alone in the open field of a graveyard. He was practicing on using his quirk.
Yin: Rise.
Soon enough spirits of the undead begin to rise from the graves. He watched manifestation of entities and zombies begin to crawl out from his commands.
Yin: Good. Now sleep.
Yin then diffuse his quirk and make the undead go back into their graves.
Yin walked over to another grave he recognized.
It belong to his mother.
Celia Hamada.
Yin: Mother...
???: Awww...So sad~!
Yin jolted before gaining his composure.
Yin: What are you doing here...You should be in prison.
Yang: Can't a father visit his son once in a while.
Yin: You're not my father.
Yang puts an hand on Yin's shoulder...
Before the grip tightened, Yin felt slight pain on his shoulder as the dark shadows surrounded them.
Yang: I need you to do something for your dear old dad.
Yin:.....And if I refuse.
Yang: If would be really terrible if something happen to your precious Auntie Jade.
Yin:...!
Yang: That's right. She's the one who been hiding you after all this time. Don't think I wouldn't find out.
Yin: Don't you fucking dare hurt her.
Yang: Just do what I say and Auntie Jade will be fine....
Yin:......I'm all ears.
-End Flashback-
Yin: After that...he told me to gather up as much information about the heroes as possible and give them to the League of Villains. If I didn't do what he say...He'll kill Auntie Jade...just like how he killed my mom...I know this doesn't excuse my actions...but I'm sorry...I-I'm
s-soo...sorry...
Teachers:......
They never expected this...
None of them had any words as the young boy was crying.
Present Mic: Little Listener...
Yin looks up...
Present Mic: Please... don't be hard on yourself. You were just put in a situation where you had no choice but to cooperate with a villain.
Yin: But it's my fault that everyone got hurt...
Midnight: No it's not...
Yin:....!
Geysis: It's our fault. We should'be realized a villain was threatening to harm one of our students. And sadly...who better than your father.
Ectoplasm: I admit. After finding out who your father is...I should've kept a close eye on you.
All Might: So Hamada-kun...Do not worry. None of this is your fault. As your teachers, we will take the responsibility.
Yin:.....But what about my punishment...I still did something horrible.
Aizawa: Ah yes. About that. We will discuss that on a later day. For now, just go back to your dorms. Class is cancelled til further notice.
Yin: And my father...?
Nedzu: We did found his body. We able to confirm that All For One not only took his quirk...but his life as well...You don't have to worry about him anymore.
Yin:.....I see...(He deserves it. Now he can rot in hell...)
Nedzu: Also. We'll be determined location on your Auntie Jade's to whereabouts and notify you when our operatives get the chance.
Yin silently nodded and left the room.
But not before the atmosphere in the faculty room turned grim. A sniffing sound was soon heard.
Aizawa turned his head to Present Mic.
Present Mic: We failed him....
Heroes: ?!
Present Mic: We failed him...I failed him... It's not his fault...How could I let this happen...? One of my own students being forced to go through all that...Can I even call myself a hero and teacher...?
Aizawa: Mic...
Eraserhead held Present Mic while he sobbed as no one else spoke a word.
-Meanwhile-
Yin was going to take his leave when suddenly saw Mikoto.
Yin: Class Rep?
Mikoto: Yin...Is this true?
Yin: W-What is true...?
Mikoto didn't answer right away but Yin already knew what he meant.
He stayed behind and heard everything.
Mikoto:.....You're the traitor?
Yin:.......
