Saya Matsukaze

As the more grounded and pragmatic sibling of Mayu, this studious high schooler serves as the treasurer for the Kawanuma West student council. While her older sister often lacks focus, this bespectacled student brings much-needed stability and a sensible attitude to her school activities. Her natural leadership and dedication to her responsibilities eventually lead her to rise through the ranks, ultimately securing her position as the student council president.
