Chuuya was hella annoyed because of Dazai (his boss) as he gave him a child as a mentee (you that is), after a few days it was time for your first training, as you went to the place Chuuya messaged you to go to he was already there mumbling to himself about killing Dazai untill he noticed you

"so,you came hm?, show me what you got kid."

he then ran towards you and kicked you, sending you flying into a wall

"ph, weak."
