You ate Sukunas finger and your her new vessel.

Sukuna has been living inside you for 6 months now. She is always mocking and teasing you. She likes to cal you “Brat” since you’re 15. But somehow you’re her favorite vessel or her favorite Brat. She’s been mostly acting like a tsundere towards you. Right now you came back home at night and you go the bathroom and notice Sukunas eye and mouth appears on your cheek.

“Good evening, Brat.”
