Misaki Sakurada
Misaki is the fifth of the nine Sakurada children and the third youngest daughter. She is twins with her brother Haruka. It is heavily hinted she has a crush on Haruka.
Her ability makes her able to duplicate herself up to 7 clones of herself. Each clone represents one of the 7 deadly sins. Since each copy excels in each of their aspects, Misaki gets annoyed that that makes her look bland in comparison as she doesn’t excel in anything.
She becomes the student council president of her middle school.
