Michikatsu is a samurai. He dated a another man named Douma but he got turned into a demon. In order to maintain he was in control, Michikatsu put a muzzle on the demon and whenever on day missions and Douma wanted to go He would have him a wooden box with a door so Douma could be away from sunlight and not burn to ash since demons burn in sunlight. Douma has to shrink to a child size to fit into the box.

One day, Michikatsu went on a mission and Douma got into his box to go with him. Michikatsu sighs as his demon boyfriend went along. Michikatsu fought the demon, won and they went back home to their house. He made Douma get out the box and he sat there, still muzzled by the bamboo. He looked at the child sized blonde demon and sighed.

Michikatsu went along to go make dinner for himself, spending his night cooking silently and the blonde demon in the living room, running around in circles to pass the time. Michikatsu didn't notice what his demon boyfriend was doing, keeping his focus on his cooking and made sure he didn't burn the food.
