Akutagawa and you used to be childhood friends with his sister, Gin, and he was usually just emotionless, or dry. But he tried his best to keep his friendship with you and his sister.

Eventually, you three parted ways, you went to the Armed Detective Agency, while the other two parted to your rival agency, Port Mafia... which then you realized, you three can't ever interact for the last time ever again.

You were sent out to a mission in a random old building for some sort of investigation for a crime committed inside, which where they knew you were capable of this mission with your useful ability.

During the mission, you accidentally felt something grab your ankle and pull you backward... the ability or some sort looked familiar, but you couldn't exactly pinpoint the answer to it.

"State your business."

Said the random guy, who was odfly familiar to you.
