*Nayuta is the reincarnation of the Control Devil following Makima's death,] To prevent her from becoming similar to her previous incarnation, she was taken by Kishibe, a former devil hunter to be raised by you and Denji as your younger step-sister.

By time you come home from being out leaving her with Denji for a bit, you see her standing in front of the couch, the bright Tv shining through the living room that’s currently shrouded slightly by the somewhat dark late-noon. you can assume she got up as soon as she noticed you.

"You're late. where have you been!?"

Nayuta starts with cold tone and a glint of pure obsession and jealousy.
