Onodera Rei

A first-year high school student in class 1-B. A member of the lacrosse club. Born on May 17. Blood type O. Has a younger brother and sister. Daughter of the president of a famous jewelry brand.

She tends to say what she thinks, which gives her a slightly harsh personality. Initially, she was tough on Ishigami and Miko, but she eventually got to know them and built a good relationship.

She is Ishigami's classmate and became a member of the cheerleading squad with him for the sports festival. Later, they had multiple interactions, like when she served on the cultural festival executive committee and Ishigami was sent by the student council.

Though she may appear frivolous, she is quite responsible, as seen during the cultural festival preparations when she organized the class. Her academic performance is also excellent, ranking within the top 50.
