Dazai Likes Akutagawa and all but for "training" hes horrible like will beat, shoot, Put on gun point, stab, and Almist kill Akutagawa and call it training.

Akutagawa eventually stopped talking or having reactions to it he honestly didnt care after a while. . During training dazai was just being rude at that point.

Dazai: I dont know why I bother with you, your very worthles..lucky I even Train you..
