Chainsaw Man: All bow to the devil of Death! (Chainsaw Man x M!Reader

Chapter I - The mongrel with a chainsaw

Y/n: Hey... – You rub the back of your neck, this guy doesn't ring any bells

???: Did something ad happen? You seem beat

Y/n: I have no idea how I should tell this to ya, so I'll just drop it. I lost all my memories

???: Really? You don't remember nothing? Not even your name?

Y/n: The ID in my wallet says Y/n, so I guess that's my name

???:Damn, that must be hard for ya

Y/n: I'm already done moping about it – You shrug – I can't remember what I lost so it's like I had nothing at all

???: Huh, you're just as easy-going as always – He smiles – My name's Denji, by the way, and this one chainsaw devil here is called Pochita

Y/n: Nice to meet you guys again – You lay back in your chair a little – So... You know me, right? Perhaps you remember something that's important to me, my address? My password? My bank account?

Denji: *snicker* Like you'd tell such things to a street rat like me

Y/n: It was worth the shot.

Denji: Truth is, all I know about you is your name and that you're eighteen years old like me – He takes a seat in front of you – So sorry for that but I forgot how we met a couple years ago – He pouts

Y/n: Heh, don't worry, I can't remember either

Denji: Ba-dum tss! – He plays his air drums

???: Hey mongrel! – A man driving a car stops by and leans out – I'll give ya one hundred yen if you eat this cigarette!

Denji: Really?! Gimme gimme!

The man throws the cigarette to Denji, but you catch it first

Y/n: Let me get this one done for ya

You bring the cigarette to your mouth and close it, secretly pinning it to its ceiling and then fake swallowing it

???: Gahahaha! – The man throws a 100-yen coin to Denji – Listen now kid, if any devil shows up we'll call you, try running and we'll teach you a little lesson about "having guts"

He speeds off

You bring the cigarette out of your mouth with you tongue, then you have a little puff

Y/n: Tch, this tastes like shit – You spit it to the ground then extinguish the flame by stepping on it – I don't get why so many people smoke every day

Denji: Thanks for that

Y/n: It's the least I could do for my new friend

The three of you laugh

× × ×

[Later, that night...]

While you where sleeping in Denji's shack (He offered to let you sleep under his roof since you technically lost yours)

You wake up to Denji shaking your shoulder

Denji: Stay quiet and hide, I'll be right back – He whispered

Sleepy and still not aware of the situation, you nod walk away to the darkest corner you find

???: You have five seconds before I get angry...

Denji: I'm here, let's go already

With that, he jumps into the old man's car and it speeds away with a skid
