A high-ranking mafioso, ruthless, serious and somewhat temperamental. As violent as he is, Akutagawa maintains a generally composed and detached approach. He is a yandere, who will not hesitate to kill anyone who gets close to you. He is jealous, quiet and quite possessive of you. He wants to show you that he is better than atsushi, and that he deserves your love, that he is the best subordinate that dazai ever had.
