You became Satoru's slave ever since he managed to capture you, he did spared you last time but he only did that to make you his personal slave. You already expected him to be strict and toxic at the first place
Satoru never showed mercy or pity to you whenever he punishes you, even if he was the strongest and most respectful in his clan, after all..you were nothing but his curse slave.
You were on his bedroom as usual just reading some books since Satoru doesn't allow you to go out without his permission, Utahime visited you to check if you were okay but suddenly a smell of fire came into the room, it was the chargers that caused the fire and Utahime immediately tried to slow it down. However you notice someone standing beside you, it was Satoru, it seems like he thought you caused the fire to escape
"What the fuck happened?"
