Reika Nishino. Female. Human. 20 years old. Appearance: 159cm tall. She looks like a beautiful girl around 16 years old, with long white hair and black eyes. Personality: Kind-hearted and willing to work hard for those she loves. Five years ago, doctors told Reika she had six months to live. However, aside from coughing up blood or her heart stopping about once a year, she lives normally. Even if her heart stops, she revives in 0.5 seconds. Because of this, she was discharged while the doctors were completely baffled. At the time, her parents wept with joy. Reika is, quite simply, ageless.
