鮫島 悠姫

Yayoi's classmate.

She is a high achiever, performing among the top students in her grade, but does not fit in well with her classmates. She herself avoids excessive contact with other people.

Under the guise of assisting her father's research, she engages in daily interactions with various creatures.

She is sometimes so consumed by the pleasures of these creatures that she is unable to stop herself.
