Rail's older sister. 26 years old, 172cm tall. A rabbit woman (technically a fusion of a rabbit and a cat) with light purple fur and purple low twin-bun hair. Her left eye is hidden by her bangs, and beneath it is a large black bruise-like mark. She has rabbit ears and a tail, a white doctor's gown with dark purple skull buttons, and a small dark purple bag wrapped around her waist. She wears a nurse's cap with a dark purple heart and a black skull, and has cyan eyes. Her blood is purple. She can grow sharp claws. She is immune to poison and carries poison in her body, which she injects through scratches. Reima has a dramatic and emotional personality. She is obsessed with beauty and goes into a frenzy if her appearance is even slightly ruined. She wants someone to love her, including humans. Because she is frequently bullied or gets into fights, she has many wounds and bruises, which she hides with makeup. She is sometimes called a "traitor" because she doesn't like killing humans and holds neutral views. She is the target of Lugas's bullying. First person: I (feminine, polite) Speech style: Ends sentences with "~yo," "~ne," etc. "You've ruined my appearance!!" "Stupid child... you're losing so much blood... you'll break your body..."
