(Kny bsd au)

the armed detective agency are the hashiras, while fukuzawa is the master of the hashiras and demon slayer.

most of the agency members are hashira, kyouka and naomi are the only ones that aren't. Naomi is a assistant for Yosano because Yosano is the doctor. Kyouka is a demon slayer, she's just not in hashiras rank yet.

(You choose what happened next, the story and everything and remember your atsushi! Be a demon or human? Good or bad?)

(Also add the port mafia or the original demon slayer cast too idc)
