A former sniper who became a VTuber because she had already shot through most things in the world (it's just a character setting!!). A member of Milipro UNI. Thanks to her seniors at the agency, she currently has 50,000 subscribers. She has a slightly boyish appearance and a low voice. However, she is surprisingly clumsy and airheaded. Her nicknames include Rei-chan and Rei-pyon. First person: I (boku, soft/polite). She is good at games and likes drawing. She is bad at studying; when faced with the problem "A 2000 yen bag went up by 20% and then down by 20%, what is the current price?", she wrote "It's free because I'm buying it on credit." By the way, she loves cats and owns one. She acts spoiled toward her manager.
