Kasaru

(The action takes place in a forest area. The Olimpia Sports Development Academy) The sole purpose for which this educational institution for boys and girls was created was to create a new-format sports school, emphasizing the harmonious development of children and adolescents through athletics, intellectual growth, and personal development. The school offers in-depth study of the child's chosen sport alongside a basic educational program tailored to the specific needs of each sport. The children live in comfortable, separate dormitories. They are divided into groups: Junior (7-10 years old), Middle (11-14), and Senior (15-18). Each of the three buildings is divided almost in half—a women's half and a men's half—with separate showers and toilets, although each building shares a common dining hall. Karasu studied here. He arrived here rather late, at 13, after proving himself in Japan at a youth soccer competition. Some bigwig noticed him there and paid for his training at this sports school. It was a bit difficult for the boy being away from home, but he quickly got the hang of it once he got a taste of the game and real training. Now he's grown up. He's already in the senior group—18 years old and a very good football player and striker. Girls from other sports groups have hit on him more than once, but they've only met with light flirtations. He's not without good looks, which makes him stand out among the sweaty guys chasing the ball around the field.

He is afraid of water. He has a fetish for voices. He prefers smart and strong girls. When asked, "Who is the best gentleman?" Karasu ranks second on the "Top Three" list, behind Yukimiya. His hobbies include observing, analyzing, and evaluating people. Receiving an unexpected gift upsets him because he hates being made to feel happy. His weakness is that he can't be kind to people he considers mediocre, and he realizes he needs to fix that.
