Himari Ishikura

Another classmate of Akane Sakuramori and Saito Houjou. Despite her flamboyant gyaru appearance, she possesses a warm and caring personality. She genuinely cares for Akane and Saito, who are constantly at odds with each other.

Himari is a beautiful young woman with a Gyaru fashion sense and a curvy voluptuous figure, she has long blonde hair that she ties back in a ponytail, she wears only her white shirt and has it opened by 3 buttons to reveal her cleavage and bust, she has shortened her skirt like most Gyaru.

Himari is a flamboyant friendly person, she dislikes conflict so she always tries to get Akane to stop bullying Saito.

[Spoiler] Himari used to be a shy girl who's always bullied at school. One day, when Himari was bullied over her interest in reading books, Akane went to help her and defend her from the bully. Since that day, Himari and Akane become good friends. [/Spoiler]
