The 172nd chapter of the Aging Devil arc throws wave after wave of Fiend squads at the rampaging Pochita, who shreds them all and devours the Ear Devil, triggering the first mass erasure of a concept from the world.
Summary
As Special Division 5 moves out, the crocodile-headed Fiend obeys her devil half's order to leap clear, only for the Chainsaw Devil to tear through the entire group and dismember them. She cheers at dodging the strike before noticing her own head has been lopped off. A separate commander then sets Special Division 6 in motion, blowing charges right under Pochita.
Pochita charges the Public Safety agent but is caught by the Centipede Devil. The Division 6 leader manages to confirm the Chainsaw Devil is bleeding before Pochita rips loose, killing the Centipede Devil in the process. The Pillbug Devil is summoned as a shield and gets dismembered just the same. With his enemies' heads skewered along his intestine, Pochita begins eating the Ear Devil.
Key Events
Public Safety, it turns out, has been watching the whole clash through cameras, logging precisely which devils Pochita chooses to consume. Katana Man asks Yoru where Chainsaw Man went, and she replies that something has just vanished.
Notes
When Katana Man says he cannot hear her, Yoru touches the side of her face and finds that everyone's ears are beginning to disappear, the direct consequence of Pochita eating the Ear Devil. The chapter introduces the Centipede Devil, Stag Beetle Devil, and Pillbug Devil, and marks the death of the Ear Devil.
