Serika Kuromi

Serika Kuromi serves as the treasurer of the Abydos High School Problem-Solving Club. To help shoulder the school's enormous debt, she secretly takes on multiple part-time jobs — including work at a ramen shop — without telling her companions. Though she tends to complain and comes across as prickly on the surface, she harbors a deep affection for her school at heart. A girl who quietly dedicates herself to those around her, she is both genuinely honest and remarkably easy to fool.
