Shion Todoroki (轟 紫音) is a former delinquent who wants to have a normal school life.


She intitially was clothed like a typical yankee look that included intimidating eyes, a surgical mask, and her hair crafted in a pompadour.

After entering high school, she has more cute appearance where she has her hair down, in a messy fashion, with a cowlick. She also starts to wear more cute clothes such as the Yumekuri Highschool Uniform and a casual blouse and skirt, but retained her delinquent jacket.

Her bust measurement is 75cm.


Her personality was typical of a yankee, a hot-headed and impatient person, but caring towards her friends.

She stills prefers to wear her jacket even after becoming a normal girl as it makes her feel calm.


Shion became a delinquent back in middle school, brandishing a yankee attitude. But she wanted to be a normal student, so she asks Miyazaki Chisaki to be her guide under Seri's advice who was her senior back in middle school.


She was a Head Delinquent in a Yukemuri High's affiliate school. But she wanted to be a normal student, so she asked her friend to contact Chisaki. She learned to wear cute clothes and her hairstyle changed. But the 2nd Head hated her so much so as to harass her friends, which made her fight the Delinquents, made them flee when Kogarashi deflects them.

After that, she became a normal student and friends with the others.


While still an average human, as a former delinquent, she possesses a strong body and conviction.
