The 155th chapter of One-Punch Man puts Garou and Bang at the heart of their duel as the Hero Hunter turns his master's abandoned style against him, while Genos makes a fateful choice to guard Tatsumaki instead of detonating himself.
Summary
Garou shifts into the aggressive Exploding Heart Release Fist, the very style Bang once relied on before creating Water Stream Rock Smashing Fist. Both Bang and Bomb are rattled, and Bomb wonders how the Hero Hunter picked up something so long buried. Bang admits Garou stole it by cracking open the dojo safe and reading the sealed scrolls. Watching his youthful method reflected back stirs old memories, yet Bang steels himself against losing.
A flashback paints Bang as a reckless brawler who kept hospitalizing anyone he challenged. Alarmed by that cruelty, Bomb confronted him, argued that raw power had not settled his inner turmoil, and beat him decisively. Told to cool his head, Bang walked away humbled, later choosing to forge a defensive art and open a dojo of his own. Bomb quietly kept tabs on that transformation over the years.
Back in the present, Bomb doubts his brother will fall back on the explosive style while being driven backward. Bang instead pours everything into reaching Garou through his fists, resolving to shed the hero mantle afterward and reclaim his role as the young man's teacher. Elsewhere, Genos and Tatsumaki are torn apart by Black Sperm's endless copies. His former self would have self-destructed, but Genos refuses, shielding Tatsumaki with his ruined body just as King's engine roars nearby.
Key Events
Garou reveals he learned the Exploding Heart Release Fist by breaking into Bang's dojo, and a flashback details Bang's violent past and Bomb's decisive lesson. Bang commits to retiring as a hero and winning Garou back as his disciple. Genos, dismembered by Black Sperm, deliberately abandons self-destruction to protect Tatsumaki, and the sound of King's engine cuts through the fight.
