Hey there, I wanted to do another X-Men evolution story. I watched a lot during the summer, and I felt that Hunter X-men is not a the full steam as it originally had. I will publish chapters of that story, but its not the main one like I wanted it to be. I hope you all understand that.

I based this one of another Demon Slayer story where Tanjiro, Inosuke and Zenitsu are sucked into a new world and have to deal with the new situation. I choosed X-men because it would be cool to see the group fighting the mutants.

In case of continty this takes place after Season 1 Demon Slayer so Rengoku is alive and in X-Men this take place mid of Season 2, after Beast had his transformation.

Also, yeah I decided to pair Tanjiro with Rogue and Kanao, I don't think its that bad, just a sharable situation. Also, because Rogue and Gambit don't go much in this show, I heard it was supposed to be a little more explore on the scrapped Season 5 but we never get that. I hope you all enjoy this.

At the city of Bayville

It was a typical night on the city, nothing to be worry about. No crime, no attack from a weird person or something else. Complete peace. There was two officers doing a night patrol on the streets, making sure that nothing was going on, so far there nothing to reports.

''Hey do you wanna grab a bite after midnight?" Asked officer one.

''Sure, I mean there isn't anything tonight so might as well.'' Said officer two.

''Sometimes I am either glad or annoyed that nothing happens at night here.'' Said officer one.

''Oh shut up, lets hear the radio and occupy our minds.'' Said officer two.

The two did that once they turn on the radio they hear something about mutants.

''tonight on ´´Truth of Bayville´´, are mutants living in the swears? Some say they might as well be tossed into the toilet like those alligators in New York.'' Said the radio host.

''Turn this off, I am not in the mood for this crap.'' Said officer one.

''Not a fan of mutants?' Asked officer two.

''I am just fine with them not causing trouble. I´m not going to poke the bear to get a point across.'' Said officer one.

''At least you´re not those lunatics that keep showing up at the Xavier institute. Sometimes people have too much free time on their hands.'' Said officer two.

''Imagine a riot done by mutants. That's a scary one right there!'' Said officer one.

''Yeah, dealing with all those powers and try to take them down, I am not paid enough for this.'' Said officer two.

''Do you see yourself as a superhero?" Asked officer one.

''oh come on man! I am just joking; I am not like those weird teams in New York.'' Said officer two.

''I know but it would be funny to see them in this city.'' Said officer one.

As they kept driving slowly around the streets they soon heard a big scream coming near a park, it was a woman scream and it was a loud.

''aaaaah!"

''What that hell?" Asked officer one in shock upon hearing that.

''Lets pull over!'' Said officer two.

The two did that and took out their guns, better be prepared than for nothing.

''Should we call for backup?" Asked officer two.

''Not yet, lets look at the perimeter and then call. We can't risk it being a misunderstanding.'' Said officer one.

''What it is a mutant or something?" Asked officer two.

''We will explain that it was self-defense, I mean it's the middle of the night and we heard someone screaming.'' Said officer one.

''What about the magnetic guy? I hear he kills people who attack mutants.'' Said officer two in fear.

''I guess we can get paid leaves or something, the point is either we do this, or we are fired.'' Said officer one.

The two went to the park with their flashlight on and pointing their guns at whatever it would move. While they kept going they smell something odd.

''Do you smell something?" Asked officer one.

''Yes, a really bad thing.'' Said officer two.

The two then saw something in the grass, a liquid and a very thick one at that. To get things even worst…it was red.

''Is that?' Asked officer two scared as his partner confirms it.

''Blood? Yeah.'' Said him in shock.

The two were now scared as they need to go back to their vehicle to call fro backup, whatever was in the park it was dangerous. However, officer two saw something nearby and that turned out to be a big mistake.

''Hey look!'' Said him.

The two hear something chewing, it might a coyote or something, but they kept walking and ended up face to face with horror itself.

''Uh?" Asked them in shock as they see this terror.

It was a human looking creature. He was pale, had blonde hair, sharp tooths, magnetic eyes and he was chewing at some old woman. Upon hearing the two approaching he stopped chewing at his meal and turn around.

''RRRRRR.'' Grunted the creature.

The two officer went pale for a moment and soon grabbed their guns.

''Oh god!'' Scream them as they shoot at the creature.

BANG Bang

Their bullets did nothing to him, he just regenerated as he stood up with a smirk, wearing some kind Japanese clothe.

''Holy shit!'' said officer one.

The creature smile at them, just with a sick grim in his face.

''Looks like I am getting more food.'' Said him.

''Oh god!'' Said officer two.

''No just me.'' Said the creature.

The creature soon disappeared, being faster than what a human eye could see and managed to slash officer two head with no problem.

Slash

''ARGH!'' Scream his partner in shock, seeing brains and guts everywhere.

''Look out! There is something behind you.'' Said the creature with a smirk as he killed the other officer.

Slash

The two officers were killed as the creature which was a demon pretty much devours their bodies.

''This is the jackpot! I don't know why we never tried this plan! But it's a much more efficient one! Ha Ha Ha!'' Scream the demon as he eats his prey.

The two cops were never seen again, police would find their remains the next day, the demon ran away to the forest to hide from the sun and wait for the night to return.

The next day

At the Xavier Institute

Charles Xavier waked up confident as usual, greeting his staff and students as they prepare for another day at the institute as they work hard to perfect mutants and humans' relations.

''Good morning Ororo.'' Said Charles to Ororo Munroe, also known as ´´Storm´´.

''Morning Charles, would like some coffee?" Asked her.

''No, I would be having my tea as always.'' Said Charles.

''that's ok.'' Said her pouring some tea.

''Where is Logan?" Asked Charles.

''Fixing the van, he said there was an oil leak.'' Said her.

''Good, that should be taken care before any mission.'' Said him.

''True, besides Scott might take later?" Asked Ororo.

''And Hank?" Asked Charles.

''Ath the lad doing some test.'' Said her.

''that's good to hear.'' Said Charles.

''Do want some leaf's on your tea?' Aked her.

''It would be wonderful, thank you.'' Said Charles.

As Charles went to grab his plates for breakfast, he saw ´´Breaking news´´ on Tv, it was mute because Ororo was just using as background, but he saw the tittle ´´massacre at the park´´ and got curious.

''Uh?'' Asked him confused as he sees the news.

''What is it?" Asked Ororo.

He turned up the volume and hear the broadcast.

''Last night, three people were mauled by some are saying a vile animal. We don't know what could it be. Some are saying it could be a lion or a bear, but investigators haven't found any trace of animal hair in sight.'' Said the broadcaster.

Charles and Ororo were horrified by that, the corpses were pretty much turned to mush. It would take a while to identity the victms. What could have caused that in Bayville?

Soon Logan arrived at the kitchen.

''Hey Chuck, morning. Listen I need to go to an auto shop to grab some parts and…'' Said Logan talking about the van and then saw the news.

The sight of those bodies made him stop, there was vile monster in Bayville and he didn't like that.

''What the hell is going on?" Asked him.

''Looks like we have either a wild animal at the loss or…something worst.'' Said Xaviers.

The professor feared that there would a be a mutant with a trait of eating human flesh, he only thought of that as just a hypothesis, but he feared that might be true.

''This doesn't feel right. We don't have any wild animal in the city that could do such things. Not even the zoo has creatures like that.'' Said Ororo.

''I agree.'' Said Xavier.

''Something is out there killing for fun. I don't know what it is but I don't like it.'' Said Logan.

''We better inform the others.'' Said Ororo.

''Just the X-men, the new Mutants aren't ready for this. We will tell them later.'' Said Xavier and the two agree with that.

In a cave

The demon was at a cave near the mountains of Bayville, there was some writing on the walls but the didn't mind that. He would just stay there until the sun goes down and the darkness was at it again.

''This place is amazing! No slayers! No weird crap! The humans are left and right easy to kill!'' Said him with a smirk.

He had just eaten 3 people, but he couldn't wait to get out and start chewing another person.

''I am going to enjoy this city.'' Thought him

Hey there, here we go. We are going to mix early 2000s superhero cartoon with mid 2010´s anime. I mean this will be awesome and yes, its kind similar to my Naruto x Demon Slayer story. I got both inspired by the same story, so we are stuck with that.

Tanjiro will be the first one to appear, but that will take either 4 ,5 or more chapters to make the X-men see that the Demon isn't a mutant and make them see there is something odd. Unlike Naruto this will be harder for the mutants to fight, not even Adamantium can kill a demon. Well, I hope you all understand this and enjoy the story.
