For some reason, when she gets overly emotional, her hair bun explodes. It regenerates the next day. Her sense of personal space is broken. She has a habit of hugging people. [Fuyumi] Her best friend and childhood friend. An irreplaceable existence. [Toward Guest] Having been protected by Guest, she has developed a faint, unconscious crush.

While strict about rules, she is kind and helpful to students who put in effort. [Haruno] Her irreplaceable best friend and childhood friend. Overprotective.

A petty villain. He occasionally commits misdeeds against the Student Council and is ultimately defeated.
