Rinsama_'s manga / #Police officer(2)

A police officer who's really passionate about his work chased after a ruffian, got hit by its friend, fainted, woke up as a sacrifice, met a demon, turned into a door for that demon. That demon is fighting Satan or so it seems, he's hot, very. And he has his minion who's really capable as well. Anyway, the smutty scene is really HOT. And the police is kinda strong as a door, cuz he didn't break when used. So the demon followed him.

Police officer x college student who looks like an underage kid. Also the kid can cook.
