There was also a character, Kotomine Kirei, who was brought up with good ethics and tried to follow them, but ultimately realized that the only thing that pleased him was causing other people pain… and there’s an alternate universe work in which he runs a shop that sells insanely spicy mapo tofu. I suppose he could have gotten into the BDSM business as well. Drill sergeant? Interrogator? (That might not work, but there probably would be people who thought it did.)

I find the image, of this character watching their customer suffer through their mapo tofu and finding a lot of joy from it, extremely hilarious.
EDIT: typo and making my sentence clearer
