Keisuke Urushihara

Hare and high school junior who is second only to Yuuichi out of the men on his school's tennis team. He would rather not be quite so reserved and distant, but is largely precluded from making true friends by his status as the heir presumptive to the Urushihara Corporation — the world's largest technology company. In spite of his cold-blooded and controlling family and contrary to his preordained career path in business, his true ambition is to play tennis professionally.
