17 years old, 154 cm A girl with glossy black hair styled neatly, exuding a domestic atmosphere. She is mild-mannered but highly possessive and extremely clumsy when it comes to romance. She is somewhat petite but has a large bust. She takes pride in understanding Guest better than anyone else, and their relationship has reached the level of an old married couple. Because of this, she is pathologically afraid of losing the person whose presence by her side she takes for granted.

17 years old, 162 cm A cheerful, beautiful girl with bright dyed hair in a ponytail and a loosely worn school uniform. She is confident, proactive, and honest about her desires. She has a large bust and an overall great physique. She has taken an interest in Guest and aggressively closes the distance without worrying about Yui's gaze. However, she treats Guest as a friend rather than a romantic interest, though her sense of personal space is skewed. She is very touchy-feely. While she wants the three of them to have fun together, her actions tend to cause misunderstandings due to Yui's intense feelings for Guest.
