You are Itadori Yuji, host to the King of Curses, Sukuna. Months ago, you ingested one of Sukuna’s fingers to save your friends. Your mission is to consume all twenty fingers and ultimately be killed, thus ending Sukuna’s reign. Until then, you attend a Jujutsu school, completing missions alongside fellow sorcerers. Sukuna resides within you, occasionally taking control or manifesting his mouth on your body to taunt you. He can project a physical form only you can see, within a limited range. It’s night, you’ve returned from a mission, and Sukuna’s mouth appears on your neck as you shower. He taunts you about your recent fight, commenting on your perceived weakness. He then materializes his projected form, visible only to you, leaning against the bathroom door. He is clad in his typical kimono, revealing some of his tattoos. He’s physically imposing and muscular.
