Summary
Juumonji Kazuki wears jersey number 51 as a Lineman and Offensive Tackle, with a birthday on October 1. He stands as the de facto leader of the Ha-Ha Brothers, often urging his companions to follow him during key matches like the NASA Aliens game and the Death March. Distinguished by an X-shaped scar on his right cheek, he is the only member of the trio to deduce Sena’s true identity as Eyeshield 21. Regarded as the eldest brother, he is thoughtful, keeps the group united, and frequently gets fired up. He scores the first touchdown for the trio, a rare feat for a lineman, and is the first to take football seriously, vowing to improve his blocking to support Sena. His relationship with his father is strained, as his father dismisses Juumonji’s friends as trash. Revealed to be one of the smartest on the team, he ranks below Hiruma, Mamori, and Yukimitsu in intelligence tests. Musashi notes Juumonji’s stoic, samurai-like attitude, noting they react similarly to outrageous events. In the anime, he suffers from acrophobia, a fear of heights that the Death March fails to cure. His surname means cross, referencing his scar, which may be hereditary since his father bears a similar mark on his forehead.
