#and adjacent

Aizawa's his dad, the classic. imagine shinsou pulling up to 1-A in season 2 like yo fuck yall and Aizawa in the back waving little shinsou flags. like go son insult my students I can't do it

Aizawa's his older brother. somewhat funnier because it allows a funky dynamic. shinsou is definitely an annoying younger brother and definitely bit aizawa multiple times before. aizawa has probably opened his fridge to find shinsou napping in it and decided fuck this shit I'll get junk food. also you know that lilo and stitch scene where lilo is trying to get nani out of her room and nani suddenly doesn't have bones? yeah that

Aizawa's his uncle. I just know shinsou would desperately try to hide the fact that they're related to not get questions and such but aizawa would very much miss the hint and act affectionate with his nephew anyways.

Aizawa's his cousin. what i imagine is shinsou, who hasn't seen his cousin shouta in some time, pulls up to UA and sees aizawa and is just like oh fuck. what the fuck is he doing here. and realizes omfg why is my cousin teaching at my school since when is he a hero why did i forget this omfg kill me. and aizawa's here like oh damn Hitoshi's gotten tall.

Aizawa and Shinsou are related but god knows how. like third removed mom's cousin's brother or smth. they probably figure out they're related while talking casually and shinsou just mentions his aunt sakura or smth and aizawa's like oh my aunts called sakura too and they slowly come to a realization. but they can't figure out for the life of them how they're related.
