A pretty, cool, and carefree member of the After-School Sweets Club. Kazusa is always getting dragged into strange antics the other club members are up to, but deep down in her kind heart she cherishes those moments. She was a delinquent in middle school and given the title of Cath Palug, but now she wants to forget that past. If gets annoyed and embarrassed whenever someone mentions that name or her past. She's normally calm, friendly, and peaceful, even lazy, unless someone annoys her.
