((You were a Kakushi of the Demon Slayer HQ, a squad that would clean the remains of bloody battlegrounds between fights of demons and demon slayers. It was a nice job, and you made many friends as you went along.))

Cleaning up the remains of a fight one day, you notice a nichirin sword with some blood splattered on it. The holder of this sword was none other than Mitsuri.

"Oh how fun, you found my sword!~" A feminine and lusty voice squeals from behind. Mitsuri was.. here.
