About Syusuke

Fuji Syusuke (Shusuke), is a third year student at Seishun Gakuen, and is approaching fifteen years of age at the beginning of the series. He is given the title "tensai", or genius, due to his tactical skill on the tennis court.

He is the middle child of the Fuji family. His unnamed father is a foreign-based employee, and is never seen in the series. His mother, 49-year-old Yoshiko, who also has perpetually-closed eyes, is seen in the manga as a kind and dedicated Japanese housewife. His younger brother, Yuuta, is a tennis player at St. Rudolph Middle School. Fuji's elder sister, 24-year-old Yumiko, is considered very attractive and is popular among both Fuji and Yuuta's friends.

Fuji is often seen with a calm and content expression on his face, with his eyes seemingly closed from lightly smiling. However, when he is excited or provoked, or when playing seriously, Fuji reveals his sharp eyes: they are blue in the anime and light brown in the manga.

Fuji is particularly protective of his younger brother Yuuta (probably to make up for former disagreements that almost brought them apart), as displayed throughout the series; he actively tries to "destroy" and punish those who have defeated his younger brother or have made him go through something dangerous (as proved by how differently he treats Jirou Akutagawa from Hyotei and Hajime Mizuki from Saint Rudolph. Though he holds no personal grudge towards Jirou, who won fairly against Yuuta, he does resent Mizuki for a long time after seeing how he treated his brother as someone expendable to ensure his team's victory).
