Marui would whine over the lack of sweets, so I would have to slap him out of complaning.
Kirihara would lose his sanity over being locked up for so many hours. I’d have to make him unconscious.
As for Niou, I would probably kill him the moment he’d try anything to annoy me.
Sanada’s case in point: I’D KILL THEM ALL
