RED BLUE(2024)

RED BLUE is an anime series following Aoba Suzuki, a lonely high school freshman trapped in a cycle of bullying disguised as "pretend fights" with his classmate Sannosuke Iwase. His life shifts when Kenshin Akazawa, a martial arts prodigy from the neighboring class, rescues him—then dismisses him as "empty." Stung by the insult, Aoba declares he'll punch Kenshin and joins the struggling Shark Gym to train in MMA. With guidance from grappler Aochi, he enters the Koshien MMA tournament, determined to prove himself against the strongest high school martial artists. The series blends coming-of-age drama with intense combat sports action as Aoba transforms from social outcast into a competitor chasing redemption and respect.
