Infinite Combo

Inside the Hero Association's offices, staff pore over the reconnaissance that Drive Knight gathered on the enemy. That deliberation shatters when a colleague charges into the meeting carrying a supposed communique, then unmasks himself as the vessel for a parasitic creature. Speaking through this puppet, Gyoro Gyoro addresses the executives, pleading that the monsters' territory be left untouched and framing the whole appeal as a bid for humans and monsters to share the world. The gesture is hollow. Destrochloridium strikes down one of the officials, and Gyoro Gyoro drops the pretense to announce an all-out clash between the two factions fought with each side's elite.

Before the creature can claim another victim, Superalloy Darkshine reaches the room and puts the parasite down without visible effort, telling the shaken officials that fear belongs to their opponents instead. Far away at the enemy's base, the monsters weigh their moves. Orochi devours Awakened Cockroach both for falling to Genos and to underline his own dominance, and Do-S narrowly avoids the same fate only because her talents prove too valuable to waste. Elsewhere Garou stirs after Saitama flattened him, crosses paths with Death Gatling, and simply chooses to rest. King crushes Saitama at a video game while, back at headquarters, Gyoro Gyoro absorbs the news of Gouketsu's death and grasps that the coming war will be harder than planned.

Gyoro Gyoro formally declares war on the Hero Association through a parasite-controlled host. Destrochloridium murders an executive during the false peace overture, and Superalloy Darkshine arrives to slay the monster and steady the survivors. Orochi eats Awakened Cockroach as both punishment and display of power, while sparing Do-S for her usefulness. Garou recovers from his defeat by Saitama, and Gyoro Gyoro learns that Gouketsu has been killed.

The installment belongs to the Monster Association Arc and was collected in Volume 15, with Zombieman and Saitama featured on its cover. Its story adapts material from webcomic Chapter 53 in part and corresponds to anime Episodes 21 and 22. A bonus page shows Tatsumaki lounging in a glamorous pin-up pose with a cocktail glass at her side.
