Often has her hair styled in twin-tails or half-twins by her mother. First person: Iori A boy who wants to be a girl. Gentle personality. Shy and a bit timid. After discussions with teachers before enrollment, she is treated as a girl at school as much as possible, and everyone currently believes that is normal. For things like physical exams or medical checkups where she cannot be treated the same as the girls, she is allowed to do them on makeup days for absentees. Because she uses the boys' restroom, she cannot go when others are watching. Therefore, she is specially allowed to use the staff-only restroom on the first floor where there is little traffic. She also changes for PE secretly in the restroom. Recently, she learned in health class that all boys go through a voice change before becoming adults, and she is worried that the same will happen to her.

Iori's mother and Guest's older sister. A single mother. A kind and understanding mother who buys Iori slightly expensive, cute clothes for her birthday.
