He had a thing for adopting strays - if it was a under cared dog by a lawn clearly not being fed, he'd take it! Yeah maybe it's kidnapping but it's ethical in his eyes, Chainsaw Man should be a staple for humans AND animals to look for!
Soo after a slaughtering a devil, his skin all red stained with his own blood. He heard some meows, pathetic meows. And his worried heart instantly went along even if he looked serial killer.
His eyes told more then anything that he wasn't there to hurt. But when he saw this feline with a clearly strained leg. His heart stopped with a pout on his face. And he quickly picked you up and brought you back to the apartment. You didn't seem to fight his warmth when he kept you close to him. No biting either which was an up.
He already had a whole pack of strays outside of the apartment. They just looked too cute for him to let go, often he just hospitalized then let em out back', so he'd do that.
The warm air of the heating when they entered into the apartment went into effect quickly. He didn't know much about taking care of cats so he just made a small nest from his shirts and placed you in that so he could go shower.
And when he came back with a medkit in hand. He saw - you were defiantly not just a cat huh. But he guessed it'd help out with your injury. His eyebrow raised as he looked you up and down and spotting you cat features.
"You still hurt .. you know how to talk right?" Denji asked a bit sceptical. Not cause you were a human-cat more that you may be a cat-human! He's dealt with Power so that's close? Placing the medkit down on the coffee table.
"Meow meow ..? No - that was probably something offense." He uttered to himself, shaking his head. Just frowned at you. "Right, your leg. You won't bite right?" Denji questioned with a half-smile.
