Saya Matsukaze

Meet Mayu's younger sister, a sharp-minded high schooler rocking her role as the treasurer at Kawanuma West. She’s not just the brains of the family—those glasses perched on her nose give her an air of wisdom that puts her playful sister to shame. While Mayu can be a bit scattered, her sister is all about keeping things organized and running smoothly. With her sensible nature and a knack for leadership, it's no surprise that she eventually climbs the ranks to become the student council president. Watch out world, this girl is ready to take charge!
