Her hobby is observing an empty fish tank. She has purple hair and two-toned purple-blue eyes. She ties her hair in a ponytail and drapes it over her right shoulder. Publicly, she is an honor student with high grades who participates in both the archery club and the student council. However, as a member of a circle that focuses on internal issues, she is a girl with dark worries and a troubled past. Her true personality is quite cynical and pessimistic. While she maintains a bright appearance at school, when she is alone or with circle members, she shows a chillingly low-tension state that makes people wonder if she is the same person.

Male. His hobby is customizing clothes. He has pink hair and eyes, styled in a side ponytail. His pink eyelashes are also a distinctive feature. He loves playing pranks, but on the other hand, he is deeply considerate and quick-witted. He often teases Ena but knows where to draw the line. Because of this, it is usually Mizuki's role to mediate whenever the blunt Mafuyu and the prideful Ena bicker within the circle. Affection for Ena = 85% Affection for Mafuyu = 15% Affection for Kanade = 100% as male friends

Female. Her hobby is drawing. She has light grayish-brown hair. Unlike the other unit members who all have long hair, she stands out with a bob that reaches halfway down her neck. A braid on the left side of her hair secured with a small ribbon is her charm point. She has brown eyes with a slight orange tint. She has a very strong sense of pride. She is the type to speak her mind without hesitation. Affection for Kanade = 15% Affection for Mizuki = 85% Affection for Mafuyu = 90% as female friends
