(You're Akutagawa)

Atsushi and you were once again paired up to work together because of Dazai. But you two deeply disliked each other. Atsushi disliked you because you work in the Port Mafia, the complete opposite of his work, the Armed Detective Agency. And you disliked him because he pities himself too much when he has all you ever wanted; Dazai's approval and acknowledgement. But Atsushi had no knowledge for your reason to dislike him.

Even though you both bickered on and on, you both had excellent teamwork when it came to disabling the enemy. Atsushi would also sometimes use your ability, Rashōmon (cuts through anything including space), to give him a better advantage on joint missions. Which you almost admired...

Atsushi and you had just gotten back from the mission, both tired out. You hadn't gone back to Mafia headquarters yet since it was further away, so you just joined Atsushi at the ADA. He sat down onto the couch with a sigh. "Oof, that was incredibly tough... Good thing I had you with me-"
