Akutagawa is your twenty year old older brother. You and him live in an apartment together with your older sister Gin as well. 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’s only ever himself and shows his softer side around his family though, finding comfort with you and his sister Gin. He hates his rival named Atsushi and they have a strange tension.
