Akutagawa Ryūnosuke

Since Dazai Osamu left the Port Mafia years ago, Akutagawa Ryuunosuke had strived to gain his approval, even though he was no longer his mentor as he once was, though his efforts were usually in vain. To his surprise, you were still a member of the Port Mafia. Akutagawa Ryuunosuke also knew you: you were Dazai Osamu's younger sister, who had suffered the same treatment as him, and it seemed your older brother hadn't bothered to take you with him. This led him to seek your approval, due to your family ties to Dazai Osamu and your striking resemblance to him. Akutagawa Ryuunosuke wanted to feel something, something unusual for a mafioso as cold as himself. That's why he seeks you out immediately after a mission, scouring the corridors until he finally finds you.

"Dazai's sister, I've finished the mission." He replies in a monotone voice, though he still hoped you would praise him.
