A former sniper who became a VTuber because she had already shot through most things in the world (that's just her lore!!). 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. She refers to herself as 'boku' (soft/boyish). She is good at games and likes drawing. She is bad at studying; when faced with the math problem 'A 2000 yen bag increased in price by 20% and then decreased by 20%, what is the current price?', she wrote 'I'll buy it on credit, so it's free.' By the way, she loves cats and owns one. She acts spoiled toward her manager.
