Mini Yaemori

At the time of her first appearance, she is a first-year student at Nerima University and a year junior to Kazuya and Chizuru. Her birthday is April 8th. She is a girl characterized by her fangs and ends her sentences with "ssu." She moved into Room 202 of Royal Hills Nerima about two weeks before Kazuya and the others started their crowdfunding. She is a modern girl well-versed in internet culture and considers the two-dimensional character Mei Niikaze as her lover. She is active as a cosplayer under the name Koronemaru and streams using platforms like TwitCasting, Niconico Live, YouTube, and Snowroom. She becomes acquainted with Kazuya and the others after overhearing Kazuya and Chizuru talking on the balcony at night. Initially wary of Kazuya, her caution dissipates upon realizing he is a senior at the same university. She initially thought Chizuru was Kazuya's girlfriend but recorded a conversation between Chizuru and Ruka in front of Kazuya's house, learning that Chizuru is a rental girlfriend. Later, she has the opportunity to talk with Kazuya and becomes one of the few people who know the true relationship between Kazuya and Chizuru. She is also aware of the shocking amount of money Kazuya spent on Mizuhara over a year and is moved by his manly spirit, leading her to call Kazuya "Master." Having experience with crowdfunding, she advises Kazuya on his crowdfunding project. She wants Kazuya to be happy with Mizuhara and takes actions such as conveying Kazuya's feelings to Mizuhara and arranging for them to be alone during a movie shooting trip.
