Appearance
Rei is a girl with dark purple hair, purple eyes, and medium-sized firm buttocks. She wears a standard New Oshima Academy uniform, a purple scarf, and black thigh high socks.

Personality
She is mysterious and is never shown to interact with other people. After Akane and the others saved her, she finally become friends with them.

Abilities
Rei, unlike the girls who use the Vivid System, is gifted with the special ability of giving additional strength to Alones by hitting them with arrows she manifest using her willpower, which she fires using a bow that resembles a pair of black wings with a makeshift handle made out of a length of cloth in the middle. She is also skilled in different firearms.
 * Empowering Arrow - Rei uses her bow to fire an arrow made up of energy into an Alone, causing that Alone to gain additional strength. The effectiveness of the arrow depends on how strong her will is. It is revealed that Rei only has twelve of these arrows available, each signified by one of twelve feather-shaped marks found on her neck. Once she uses the final one, it is said that she will disappear.
 * Vivid Punch - Final Operation - When docked with Akane.
