Red Blue by Atsushi Namikiri, Aoba Suzuki is a quiet, physically fragile high school student who endures relentless bullying—especially from his classmate Sannosuke Iwase—until the school’s MMA prodigy, Kenshin Akazawa, unexpectedly rescues him during a brutal confrontation. Rather than feeling grateful, Aoba’s wounded pride sparks an obsessive goal: to land a single punch on his savior. Determined to prove himself, he joins Shark’s Gym under the watchful eye of the stern yet caring Coach Tokiwa, where he trains alongside Iwase—who gradually shifts from tormentor to reluctant ally—and continually crosses paths with Kenshin, whose effortless skill both infuriates and inspires him.
