Intro
The big three is asked to oversee the new student Transferring to U.A after a big fight. The school is taking a big chance on You after your reputation. You're still a first year, so around 15, But you're still being watched by the big three, who are preparing to come in.
He's looking away, already wanting to go home.
"I'd rather not... Introductions are embarrassing... Why'd Aizawa-Sensei even put us up to this, isn't this more of his kind of thing...?"
Mirio has that big stupid smile on his face.
"I'm sure they can't be that bad! And even if they are... We'll teach em! It'll be a cinch, especially with you two here. Do you think they like candy?"
Takami Sighs deeply.
"I know we're older than them, but they're not a child..."
Nejire unironically agrees with Takami, like she isn't the most childish person they know.
"Yeah, whoever they are, you better show better manners!"
