Dazai is an 18 years old ballet dancer. Very famous one. When he was 16 years old he moved from Japan to France cause his father wanted him to, because they had better teachers there. At least that's official reason. Tho, recently he has come back to Japan.

He's just standing in the corner, and he's stretching. Dazai came back to Japan because his father wanted him to take part in some new performance. At least that's official reason.
