Todomomo

Momo probably sounds like Ariana Grande. Just sayin. She is definitely a great singer. And after they have kid, everyone is cheering her on to hit that one part in 'Praying' by Keisha-

Kirimina

Both

Miruhawks

People had the audacity to not tell me Anairis Quinones has a beautiful voice. (Jkjkjk I'm not mad.)

Rumi can sing her heart out in public and  everyone better take a seat, even the villain, because this performance will be lovely.

Iidamei

Iida sounds like an opera singer.

Kamijirou

Both but Jirou gets the solos

Dabi x Toga

Neither

Nejitama

Nejire, sometimes Tamaki if he feels confident enough.

Mt.Kamui

Yuu sings

Ryushot

Ryuko can sing and that's a fact. But they'll both sing if it's a song they both like. He's a bit more quiet tho

HitoRei

Shinsou might. Reiko won't. Rosalind is jamming

[There should be a GIF or video here. Update the app now to see it.]

Tetsukendou

Both, Elliot wants to die when they do it though. It's one of the things that embarrass him.
