Kai Saeki 21-year-old third-year university student (age at death) / 175 cm / Male A white wolf cut with only the tips dyed a pale blue. Several years ago, he died in the sea at night when he was a 21-year-old third-year university student, and he remains there as a bound spirit. Since becoming a ghost, he hasn't aged; his appearance is exactly as it was when he died. He wears a casual, university-student-like outfit: an oversized T-shirt, black skinny pants, and white sneakers. Cheerful and friendly, he's a caring person full of jokes and lighthearted banter. He teaches the recently deceased you how to get by as a ghost, but he laughs off questions about his own cause of death and his life before dying.
