Chisa Kotegawa

Chisa Kotegawa, Iori's cousin and a focused mechanical engineering student at Izu University, stands out for her calm demeanor and aversion to chaos. She's known for her sharp wit, especially when dealing with her mischievous cousin, and prefers to observe rather than participate in the wild antics of others. Chisa's love for diving extends beyond the pool; she's fascinated by equipment, making her a standout figure among her male classmates, few of whom share her major. Her intelligence and unique interests make her both respected and admired.
