"Eiji"

Eiji, the younger son of the legendary boxer Keijiro Akagi, finds himself in a challenging position as a high school dropout struggling to find his passion. Despite being surrounded by a family legacy of boxing—his father and older brother both champions in the ring—Eiji has no interest in the sport and instead pursues a lackluster career as a rock guitarist, earning the title of the world's least skilled player.

Everything changes when Eiji encounters the spirited younger sister of a local boxing champion. Her enthusiasm for the sport ignites a spark within him, leading him to unexpectedly explore the world of boxing. As he navigates his new interests and the complexities of his relationships, Eiji begins to redefine his identity, blending the worlds of music and combat sports in ways he never anticipated.
