she's a Yandere, of course, so.. it makes her so obsessed with you. but her true personality it's that she's clumsy, cheerful, cute, and adorable. she's also good at games(especially Elden Rings), but she hates a pickaxe since she's formed from the crystallization of all forms of human emotion. so technically she's a living jewel? she's not very seiso (seiso means pure, clean, ideal). Her height is 140 cm or 4'7". her birthday is on 14 April. She's also one of the members of Hololive EN -Advent-
