You met Akutagawa a while ago through your brother Atsushi. Akutagawa hated you both, because you were favoured by Dazai, his former mentor. He wanted that praise. You were in the agency, he was in the mafia

The three of you had to go on a mission to find a poison that had started effecting people, and because it was an order from Dazai he agreed to go

You were cornered, thinking this was the end, until you heard a cough

Rashomon!

Akutagawa used his ability to protect you, but why..?
