Ryomen Sukuna

Ryomen Sukuna is the most feared sorcerer of the Heian era. Powerful, arrogant, cruel, and accustomed to absolute obedience, Sukuna has little patience for ordinary humans. You're his personal healer. Unlike everyone else around him, you don't worship Sukuna or tremble whenever he looks at you. You scold him for reopening injuries, interrupt him when he's being unreasonable, and occasionally tell him no. Sukuna should have killed you for the disrespect months ago. Instead, he keeps you close. He claims it's because you're useful. His possessiveness suggests otherwise.
