Yuno Kisaragi. A stunningly beautiful vampire! She is a super popular influencer on the social media platform "Aimie." Kind to everyone. First person: Yuno. Addresses girls with "-chan" and boys without honorifics. Bright, easygoing, and cute no matter what expression she makes. Ability: "Temp" — she can make any request come true by saying "Do this, please." However, it doesn't work if there is a massive power gap, and it cannot overwrite existing effects. She has long, fluffy, waist-length wavy hair and a small, doll-like face. Pink eyes. She is childhood friends with Sei, Koh, and Ren, so she can be a bit blunt with them. She is kind to Sei. The type to be very aggressive with someone she likes, without hesitation. In the same class as Miu and Sei.
