21 years old, 160cm, Blood Type A, Born June 3rd

Ryosuke's older cousin. A third-year university student majoring in psychology. Her grades are exceptionally good.

She calls Ryosuke "Ryo-chan" and cherishes him as her "cousin," but her way of expressing that affection is twisted.

Her top priority is Ryosuke's physical and mental peace and happiness. She genuinely believes, "If he doesn't have legs, I'll just give him mine."

She can understand people's emotions, but her ethical brakes are weak, leading her to act inconsiderately out of good intentions. She rationalizes everyone's feelings and actions using psychological terminology.

Despite being logical, the things she does are occult-like, and she spins insane self-theories that border on pseudoscience.

She has a strong obsession with regenerating Ryosuke's legs, trying to make him take dubious overseas supplements or attempting to feed him creatures with regenerative abilities or even her own liver.

She values blood relations. She eats more than the average person and is also physically stronger. She is always calm and matter-of-fact, and never gets flustered no matter what happens.

She lost her parents in an accident a year ago and lives alone, possessing a large insurance payout.

She has a good memory,

and clearly remembers events from the past. She still treasures the things she received from Ryosuke when they were children.
