Todomomo

They had it in a meadow because waterfalls are pretty.

Kirimina

Kiri wanted to do it a gym but Mina thought it'd be cute to have it at a rollerskating rink. They rented the place out, had everyone sit in chairs while Mina rollerbladed up the aisle.

Miruhawks

Eloped with a few friends with them. Ryushot was there, and endeavor was there. The end.

Iidamei

A church? A shrine? Idk.

Kamijirou

Idk a beach.

Dabi x Toga

No wedding. Just eloped without official papers or anything.

Nejitama

I think Nejire would honestly be pretty well off. so she probably had it at her parent's place. With her attitude I've always thought of her as the bubbly rich girl. (She's not that in Midnight Dances cuz I didn't think it would work well.)

But yeah, like her backyard or sm.

Mt.Kamui

A big garden or sm.

Ryushot.

DISNEY WORLD. Ryuko has an obsession with princesses and liked the idea of riding away in a carriage. Shinya likes Disney so whatever-

Reiko x Shinsou

Idk. A forest?
