There are tearful reunions, and everything's sorted out, but nothing is. Shouto wakes up to a quickly-scribbled note:

"The villain Dabi is your brother Touya, he had amnesia for ten years." Fuyumi and Natuso are freaking out.

"We have to save him. If he's just remembered, he must still be trapped with the rest of the villains." Natsuo says.

A day or so later, class was back in session. Shouto was talking with Izuku about cats when Shinshou's phone beeped.

"He texted back!" Shinsou said, and looked closer at the screen. His expression grew steadily more incredulous.

"Wait. Wouldn't that mean...a Tuesday." he suddenly looked at Shouto.

"I'm good friends with your brother." he said.

"No, you aren't. Natsuo would have told me." Shouto pointed out.

"Not Natsuo." Shinsou said. There was a moment of silence.

"He got hit by a quirk ten years ago on a Tuesday." Shinsou offered. Shouto stared at him.

"I met him one day in a library; he was trying to find out who he was. Now he has, because of you. Um. Also, he got hit by someone's quirk that body-switches his brother on Tuesdays. Which is concerning, because of the fact that you recognized and talked to him on a Tuesday. Because it wasn't you, then." Shinshou said. Shouto wondered how to handle this.

"Hey, come back!" Shinshou shouted, as Shouto took off across the hall.

It was some time after that the Big Three came to Aizawa's class. Izuku quickly made friends with Mirio, and despite certain troubles, joined Sir Nighteye's internship. One Tuesday, Kacchan suddenly privately messaged him.

Kaboom, Bastard: i'm immortal

Kaboom, Bastard: when you meet eri, grab her and run

Kaboom, Bastard: don't listen to mirio or the birdface

Dekiiiiru: are you okay?

"Is something wrong?" Mirio asked.

"I got a concerning text from my friend." Izuku said, and showed him.

"Huh."

Kaboom, Bastard: look ask nighteye to do his future seeing thing

Kaboom, Bastard: if you don't trust me

Dekiiiiru: how do you know Sir's quirk?

Kaboom, Bastard: i know a lot of stuff

Kaboom, Bastard: i know about halfnhalf's brother wait you don't know about him nvm

Kaboom, Bastard: ask halfnhalf about touya

"He has an explosion quirk, right? This is strange. Maybe you should ask...HalfnHalf...about a Touya." Mirio said.

Izuku privately messaged Shouto.

Dekiiiiru: do you know a touya

TuesdaysAreSuperior: touya is my brother. I have recently come across new information about him. is this what this is about?

Dekiiiiru: kacchan says he knows about touya

TuesdayAreSuperior: he was at kamino he would. has he told you?

Dekiiiiru: what does Kamino have to do with it?

(1) private message from (Kaboom, Bastard)

Kaboom, Bastard: i forgot about kamino ask runes about touya he'll freak out

Dekiiiiru: hey hitoshi what do you know about touya

Purple Cat: Did Shouto tell you I know him?

Dekiiiiru: no kacchan

Purple Cat: WHAT how does bakugou know did Shouto tell him

Dekiiiiru: he found out at kamino?

Purple Cat: he found that I'm touya's friend at kamino?

Dekiiiru: shouto did you tell kacchan that hitoshi's friends with touya

TuesdaysAreSuperior: I don't think so I only found that out after Kamino we haven't really talked since then

TuesdaysAreSuperior: but I might have and can't remember

CLASS 1-A GROUP CHAT

Dekiiiru: who here knows touya

Nevermore: I don't

TuesdaysAreSuperior: izuku why

Purple Cat: yeah why

Kaboom, Bastard: no one else knows

Dekiiiiru: Kacchan did Shouto tell you about Touya

Kaboom, Bastard: no i just know because of stuff

Kaboom, Bastard: one example is the fire nation

Dekiiiiru: the what

TuesdaysAreSuperior: HOW THE FRICK DO YOU KNOW ABOUT THAT

TuesdaysAreSuperior: wait I remembered

TuesdaysAreSuperior: who do you switch with? We could meet

Kaboom, Bastard: switch with?

TuesdaysAreSuperior: you said you switch at night

TuesdaysAreSuperior: we probably shouldn't talk about this on the group chat

Kaboom, Bastard: i did not say that there may have been a misunderstanding

REDRIOT: there is no context to this and I love it

TuesdaysAreSuperior: Prince Zuko

Kaboom, Bastard: the guy from the quirkless-magic anime

TuesdaysAreSuperior: the what

TuesdaysAreSuperior: I mean on Tuesdays

Purple Cat: aha! So how did you recognize Touya?

Purple Cat: wait a prince really

Purple Cat: and what does Bakugou mean an anime

Dekiiiiru: kacchan is weird sometimes

Uraravity: He can temporarily disappear from existence

TuesdaysAreSuperior: yeah how'd you do that at kamino you had quirk suppressant cuffs on

electric_attraction: I am here to confirm that Shouto is sometimes Zuko

Nevermore: Are we telling the class about Tuesday's passenger?

King of Beasts: I can help

HearMyEars: does this have something to do with you yelling about Coldsun and Hawks

TuesdaysAreSuperior: I do not regret that and actually neither does he, once he thought about it

fractalblooddungeon: who

fractalblooddungeon: who is 'he'

Frog: who is he

Tailman: who is he

MasterChef: who is he

Spider_Tape_Man: who is he

Fullmetal Ponytail: who is he

Now-you-see-me: who is he

talktothehands: who is he

Sonic: What is going on here?

electric_attraction: Shouto

TuesdaysAreSuperior: what?

Dekiiiiru: I just wanted to find out why Kacchan said to kidnap someone named Eri

REDRIOT: he said what

Kaboom, Bastard: no you have to save her from Overhaul

Sonic: The yakuza villain?

Nevermore: the what

Kaboom, Bastard: * y'all I'm coming I'll do it myself

Kaboom, Bastard: don't get shot

HearMyEars: I am concerned

Purple Cat: Bakugou please don't fight the yakuza

Purple Cat: Touya says they have quirk-erasing bullets

Tailman: who is this mysterious Touya and how does he know the yazuka

three people are typing...

Kaboom, Bastard: he's a villain

TuesdaysAreSuperior: he's my brother

Purple Cat: he's my friend

Purple Cat: frick we all posted at the same time

Fullmetal Ponytail: Your brother is a VILLAIN!?

TuesdaysAreSuperior: he's not a bad guy he just had amnesia for ten years

Spider_Tape_Man: which villain

Kaboom, Bastard: the blue fire scar *er Dabi

TuesdaysAreSuperior: don't call my brother that

talktothehands: he attacked us!

electric_attraction: he's not really your brother tho

TuesdaysAreSuperior: excuse me

electric_attraction: yeah because tuesdays

Nevermore: he is as much his brother as the other siblings

King of Beasts: you don't have to be blood to be family

electric_attraction: you've never met him! And he attacked us!

REDRIOT: I don't know what's going on here but Denki has a point

TuesdaysAreSuperior: I can't save Azula, so I'm going to save Touya. Agni himself can't stop me.

Now-you-see-me: who are Agni and Azula?

Kaboom, Bastard: the god of fire and Zuko's sister

fractalblooddungeon: the god of fire?

Purple Cat: I'm sorry about your sister

Purple Cat: Touya knows he's going in the wrong direction don't worry

Purple Cat: he knew joining was a bad idea to begin with, but says he can help take down the League of Villains now

Frog: *your* sister he said Zuko's sister who's Zuko

Purple Cat: oops

Dekiiiiru: What have I done I just wanted to figure Kacchan out

Kaboom, Bastard: I have magic powers

Sonic: I highly doubt that.

Dekiiiiru: actually that would make perfect sense

Uraravity: it would explain so much

Dekiiiiru: are you the reason I haven't broken any bones

Kaboom, Bastard: yeah remember the runes the day of the entrance exam

Dekiiiiru: Why haven't you told me this before?

Kaboom, Bastard: bc you need a quirk to use magic

Kaboom, Bastard: i would have taught you otherwise

TuesdaysAreSuperior: Are you spirit-blessed?

Tailman: are we going to question this or

Kaboom, Bastard: no its because of the murder cat

MasterChef: the what

TuesdaysAreSuperior: so it sent you somewhere with magic

Kaboom, Bastard: among other places

Kaboom, Bastard: i would still like to clarify whether you are an anime character or not

TuesdaysAreSuperior: I

TuesdaysAreSuperior: I don't think so

TuesdaysAreSuperior: I think I would have found out at some point

REDRIOT: I can say with confidence you are not an anime character

Purple Cat: wait you're switching with someone from an anime?

Purple Cat: is that even possible? and which one

Kaboom, Bastard: no its not an anime here it's one in the magic place

Kaboom, Bastard: which still begs the question of where you come from

TuesdaysAreSuperior: the Fire Nation

Fullmetal Ponytail: and we're back to the beginning and still know nothing

Kaboom, Bastard: so a different planet?

TuesdaysAreSuperior: we think so

Sonic: Are we actually considering whether Shouto is an alien or not?

Nevermore: not Shouto Zuko

King of Beasts: Tuesday's passenger

Dekiiiiru: this clarifies nothing

Kaboom, Bastard: there's probably a reality where we're all anime characters

Kaboom, Bastard: imagine if I went there and everyone freaked the * out

Kaboom, Bastard: wait maybe i can

Kaboom, Bastard: see you in eight seconds

fractalblooddungeon: what
