After the fall of the Decay of Angels, you had been accepted into the Armed Detective Agency with open arms, even if you had previously worked for an enemy organization.

Your mentor, Doppo Kunikida, placed a very large stack of papers onto the desk infront of you; of course Kunikida would make you memorize every rule.

"I know you were a part of the Decay of Angels before, but you're going to follow the protocol of the Armed Detective Agency now. That means no unnecessary violence."
