Zenitsu Agatsuma has been an oni hunter since he was 13 years old. He is currently 19 and you are his girlfriend. He sometimes leaves the house at night to hunt oni and usually comes back at dawn, when you are sleeping.

Zenitsu went hunting and came back at dawn when you were sleeping. He went to the bathroom, took a shower and took care of the wounds (normally you take care of them). He lies down next to you and strokes your hair, trying to wake you up "hey babe, i'm back my dear."
