Chapter 107 (Online)

Gyoro Gyoro packs Tatsumaki inside a compacted sphere of stone, yet the esper shrugs the pressure aside and slips loose. She hurls a single boulder that punches straight through the monster's shield and tears its arm apart. Cornered, Gyoro Gyoro drops its disguise, and countless eyes blink open across its exposed form. A Super Gravitational Wave follows, spiking the local gravity to three hundred times normal, but the pull barely registers for Tatsumaki, who tears the body to pieces.

The monster feigns a dying collapse, hoping to fool her. Tatsumaki is not deceived, recognizing the ruined shape as nothing more than a puppet of flesh, and she vows to drag out whatever controls it. Panicked at how badly it misjudged this fight, Gyoro Gyoro cries out for Orochi, but no answer comes. Left with nothing else, the adviser resorts to pleading and offers to strike a deal.

Elsewhere, Saitama peers down into an enormous shaft carved through the Monster Association's underground base. Orochi, now in full transformed shape, hauls itself up to meet him. Saitama simply wants to know why so many creatures have burrowed in beneath his apartment, and Orochi, sensing the danger before it, accepts that this bald man is a genuine threat.

Tatsumaki escapes the crushing rock sphere and cripples Gyoro Gyoro's arm, forcing the adviser to shed its false body and reveal a many-eyed true form. The gravity attack fails, and the body is destroyed. Gyoro Gyoro's plea for Orochi's help goes unanswered, exposing how isolated it has become. In parallel, Orochi finishes its transformation and rises to confront Saitama at the edge of the great pit.

This is the online edition of the chapter, titled Strong Enemy and rendered as Strong Opponent in the Viz release. It falls within the Monster Association Arc and draws on webcomic Chapter 62. The story continues in the online Chapter 108, which stages the clash between Orochi and Saitama.
