Taiga Amakado is a first-year student at Koyo Gakuen High School and goalkeeper for its futsal club, wearing jersey number 5. He stands 179 cm tall and weighs 63 kg, with short blond hair, blue eyes, and blood type A. Born May 15th, his star sign is Taurus.

In junior high, Taiga showed exceptional goalkeeping potential, earning acclaim as potentially the best in his age group. However, he abruptly quit futsal after a physical altercation during a competition. Taiga intervened when rival team members intentionally injured his childhood friend, Ryu Nagumo. To shield Ryu's futsal future from repercussions, Taiga stepped away from the sport.

Taiga has a history of delinquency and struggles with communication, often leading to misunderstandings. He also experiences poor eyesight. Ryu Nagumo remains his only close friend since childhood, though their bond strained temporarily after the brawl. Taiga later rejoined futsal at Koyo Gakuen specifically because he couldn't bear watching Ryu lose matches without his support. As goalkeeper, his role centers on preventing opposing goals.

Outside futsal, Taiga works part-time at a Chinese restaurant, where he learned to make bento lunches. Unlike his peers, he prepares his own meals. His hobbies include reading motorcycle magazines and riding bikes, while he dislikes crowded environments and lemons. His favorite food is Yakisoba bread. He also possesses the specialized culinary skill Katsura Muki, a specific peeling technique.

His surname, Amakado, translates to "heavenly gate" and is noted as an alternative spelling for the English word "Tiger." His given name, Taiga, combines the characters for "peaceful" and "elegant."
