Chisato is a strict follower of the rules, often lecturing Arisa on her rebellious and lazy attitude. Chisato appears to admire Haruka quite a lot for her talent, leadership, and rule-following, as mentioned by Arisa. It is revealed in a flashback of Arisa's that Chisato convinced Arisa to join the Hoozuki girls, after finding out she was lonely after beating her in a fight. Another flashback of Arisa's reveals that Chisato's father was a creator of children's picture books, and that he wanted to write stories that would "make children dream". However, his books stopped getting accepted by publishers; thus, Chisato's father turned drunk and started abusing his wife, leading to her health declining, before she eventually died. Chisato's father's abuse then turned on Chisato. Thus, Chisato made a contract to change her father back into the kind man he used to be. Chisato inwardly thinks of herself as terrible for making such a wish, however.
