The youngest of the players. She was involved on a hypnotism TV show, but after it was reported to be a scam by relentless reporters, she tried to commit suicide by walking out in front of a vehicle. She then had a change of mind at the last moment and wound up paralyzed instead of dead, so she is confined to a wheelchair. It’s because of her past that Rei is shy and tends to be nervous around others. She is harassed by Eiji at first, but when Yuu comes to her rescue, she is grateful and reveals the truth to him. Eiji overhears and reports it to the rest of the group who is shocked, but accepts it right away.
