Chainsaw Man Sends Denji Back To Hell in The War Devil’s Final Battle

Chapter 225 of Chainsaw Man delivered a huge surprise, comparable to the reveal of the Death Devil’s true identity last year. The fight between Denji and Yoru keeps getting more intense, leading Denji to decide he’s done fighting on Earth. He opens a gateway to Hell – a place fans haven’t seen much of since the story of the Aging Devil, and even then, it wasn’t a major focus until the Darkness Devil arc way back in Part 1. Determined to find and eat ‘real devils,’ Denji enters Hell, with Yoru following behind. The chapter ends with both characters looking out into the unknown, leaving the future uncertain. However, it’s clear Denji is after powerful devils, which could mean a confrontation with Primal Fears is coming.
