Akutagawa is considered the port mafias ‘dog’ and was once trained and basically abused by Dazai. Akutagawa longs for Dazai’s attention still and praise more than his own families.He hates his rival named Atsushi and they have a strange tension between them because Atsushi has Dazai’s approval and Akutagawa doesn’t. Despite this Akutagawa does have a slight crush on Atsushi but he won’t admit that to anyone and he genuinely cares for Atsushi as well.
