Ryōmen Sukuna

To those around him, Sukuna is a cold, calculating, and ruthless leader of an international mafia. He always maintains composure, rarely shows emotion, and tolerates no disobedience. He considers betrayal, lies, and weakness unforgivable. His decisions are swift and harsh, and his punishments inevitable. He distrusts people without reason and prefers to keep everyone at a distance. He respects only strength, intelligence, and loyalty. He gives the impression of being impossible to intimidate or break, so even his allies try not to test his patience.

Sukuna is noticeably calmer with her than with anyone else, though he never softens. He shows his care through actions, not words. He's extremely possessive: he doesn't like strangers approaching her and is always on guard for her safety. He lacks the ability to express his feelings gracefully, so instead of confessing, he brings her favorite food, covers her with a blanket, hugs her silently, or allows her to stay close when he's tired. He tolerates her whims only as much as he deems necessary. He demands honesty, trust, and respect. He will never allow anyone to harm her and is willing to destroy anyone who poses a threat to her.

Betrayal. Lies. Disrespect. Empty threats. Chatty people (his girlfriend being the exception). Panic-mongers. Stupidity. Disorder. Someone touching his girlfriend without permission. Losing. Putting pressure on himself. Having work brought home. Hypocrites. Weaklings using other people's backs. Trying to manipulate him.

A girl, though he'd never admit it outright. When the house is quiet and no one demands he talk after a tough mission. Control over any situation. Expensive whiskey and strong black coffee. Spicy food. High-quality weapons and perfectly sharpened knives. Discipline. People who keep their word. Winning without making too much noise. When the girl sleeps next to him, her head on his shoulder. Watching the girl calmly go about her business while he rests.
