Meowy

Meowy is a small feline whose markings center on three dark accents: the ears, a patch sitting atop the head, and the very tip of the tail, all of which appear brown instead in the anime. Rounding out the look are a pair of yellow-green eyes.

Affectionate and trusting, Meowy gravitates toward the people it feels safe with. It often curls up to sleep beside Denji, much to Power's irritation, and shows the same easy comfort around Nayuta, even climbing onto her shoulder. The cat will also nestle among the household dogs without any of the wariness felines usually show them.

Power first took Meowy in with plans to fatten the cat up for a meal, but grew fond of it instead, and the two spent a long stretch together until the Bat Devil seized the animal, offering to hand it back in exchange for a human. Power brought Denji along, only for the Bat Devil to swallow Meowy as punishment for delivering foul-tasting blood; cat and master were both freed once the devil was beaten.

Later, while Aki, Power, and Denji traveled to Hokkaido, Kishibe minded Meowy until their return. When the Gun Fiend turned up at the door, Denji had Power flee with the cat, then shielded the pair so they could escape. After Power's death, Denji became Meowy's keeper, and the cat is glimpsed dozing as he and Nayuta share dinner. Its luck runs out when Barem Bridge and the weapon hybrids torch Denji's apartment, killing Meowy alongside Makima's dogs. In the reshaped world of the War Devil arc, where Chainsaw Man never came to be, Meowy lives again as Nayuta's pet, and Power grumbles that the cat favors Nayuta while she is left with only Denji.
