Does anyone know all of the adults ages?? I’m just curious lol

Masaki: Late 20s to earlier 30s
Hiromu: 32-33
Yuuki: 20-21
Matsuo: 32-33

Ohhh what about Michi’s dad and the twins?

I'm not sure about their ages. I think that Oto is most likely in his late 20s or early 30s, and Yuuto and Shuuto are in their 20s.
