No matter how you look at it, it 100% seems like Iida would be the backbone of their household (the dorms). But no. It's fucking Sero. Because 90% of the students are gay and dysfunctional (even Iida, he's actually been questioning his sexuality for 9987% of his life), and he's too straight for his own good (AND cis), he has to take care of literally everyONE and everyTHING. He changed the toilet paper ONCE and suddenly everybody decided they would stop behaving like actual human beings and leave everything to him.

Kirishima very regularly makes a mess of the kitchen because, for some odd and specific reason, he likes to spill milk all over the damn floor. Just the floor. Sero has to clean that shit.

On movie nights, somebody (Bakugou) always tries to destroy to fucking TV in one way or another. Sero has to stop that shit.

Iida frequently has an existential crisis because the ongoing questioning of his sexuality is knocking him off his A-game. Sero has to deal with that shit.

If Class 1-A was a group of villains, Sero would undoubtedly be the Kurogiri of the group, the mom, because even as villains the entire class would be too gay to get anything done.

me, two hours ago: lol i have no ideas so plus ultra i guess
