In an era where MMA has exploded in global popularity—from the heyday of PRIDE in Japan to the UFC worldwide, and domestic promotions like RIZIN and BreakingDown—a new manga has carved out its own dark corner of the ring. Red Blue (Reddoburuu), written and illustrated by Namigiri Atsushi, began serialization in Weekly Shonen Sunday in 2022 and received a live-action TV drama adaptation in 2024. But unlike most sports manga, it throws friendship and teamwork out the window.
Note: The following contains spoilers.
Rejecting Positivity: A Twisted Dream Drives the Plot
Protagonist Suzuki Aoba is not your typical hero. Weak, sickly, poor, and gloomy, he has no dreams—until the day he is saved from bullies by the charismatic Akazawa Kenshin. Kenshin is a prodigy in the fighting world, bright and popular, who doesn’t even remember Aoba’s name after six years in the same class. He offers to train Aoba, pushing toxic positivity with lines like “I’ll make sure you don’t get bullied again” and “You really are empty, aren’t you?” These words ignite a twisted obsession in Aoba: he wants to punch the man who saved him. So he enters the world of MMA, determined to defeat Kenshin.
Fighting Without Knowledge: Clear Strategy Over Blind Guts
What sets Red Blue apart is its ability to explain why each technique works, even for readers unfamiliar with MMA. Aoba’s growth from a beginner relying on limited ground game to a calculated grappler is depicted with overwhelming realism. The manga never falls back on pure willpower; every move has a clear purpose. One memorable scene shows Aoba interpreting an abstract coaching tip—”Imagine a giant behind you”—into his own concrete understanding: moving his body large and firm. This trial-and-error process makes his progress feel earned.
A Dark Aesthetic: Winning at All Costs, Even as the Villain
The manga’s realism shines most in its ruthless portrayal of competition. In one fight, Aoba deliberately attacks his opponent’s old injury, drawing cries of “foul” from the crowd. But Aoba doesn’t care about being liked; he cares about winning within the rules. His opponent later admits his own foolishness for entering injured. Aoba’s coldness is not lawlessness—he respects the boundaries of the sport, which makes his unyielding drive for victory all the more compelling.
Highlights: MMA Koushien and the Finishing Triangle Choke
A major turning point is the nationwide high school tournament “MMA Koushien,” where Aoba faces flashy, high-ranked opponents with his relentless, patient ground game. As the story moves into the professional arc, Aoba evolves from a surprise attacker into a legitimate grappler. His signature move becomes the triangle choke, a clear finishing technique that raises the clarity of every match. The way Aoba sets up the triangle becomes a thrilling puzzle for readers—a perfect fit for animated adaptation with soundtrack and direction.
Red Blue is a revenge entertainment that anyone can enjoy, regardless of MMA knowledge. Its greatest charm lies in its damp, simmering heat—the polar opposite of the refreshing cheerfulness found in typical sports manga. The protagonist who says, “If you hated me once, then keep hating me forever” is a rarity in any genre. With Aoba now close to catching up to Kenshin, the eventual clash promises to ignite even greater momentum.
