This is one of a couple of story ideas I've had for a while, so this story will only have 1 chapter until it gets enough follow, favorite and review. I will have more 1 chapter stories that I will continue on if it gets popular enough, so check it out when it comes out. but now to this story

Okada Izou, after waking up in a ten year old's body for no reason, had been trying to survive as quietly as he could.

He didn't know why he has been summoned to this time or in a body of a real person instead as a Servant. So he's survived as best he could until he could figure out why he's here. It led him to take odd jobs as a handyman who knows how to use a sword. Just like in his first life and class, he became an Assassin. Izou had walked over more than half of Japan in the three years he had been here, and for that he only had two words.

"FUCK THIS!, fuck Alaya, fuck Gaia, damn it fuck Zelrethch if he's the one behind this!".

Okada Izou is lost. After he took an escort job that was boringly quiet, but on the way back he had gotten lost. For two days now he had gone without meeting a single person, and his rice balls had run out.

Why me, why can't I do something simple without a problem coming to fuck me over. I swear, when I get hold of whoever put me in this body I will-". He didn't finish his thought before he saw a house further up a hill. Oh, I didn't see it on the way here, well looks like I'll have some luck. It didn't take a second after Izou thought of it before it started raining.

"FOR FUCK SAKE, DAMN MY E-RANK LUCK".

The house didn't look too good when Izou had gotten closer, it had obviously been abandoned for a while, but as long as it had a roof it was fine. As Izou opened the door and stepped inside, he smelled a familiar but unwelcome smell, the smell of blood, and a lot of it too.

The Manslayer tried his best to activate his Presence Concealment Skill, but due to it not being as mental than a physical Skill, and the physical body he has now, it is closer to D rank instead of B, but that didn't stop Izou from hiding in the shadows.

Izou started sneaking around the house, and it wasn't long before he determined that the smell of blood was coming from the second floor, which was pretty nice for an abandoned house. But before he could get to the second floor, he heard footsteps.

Izou immediately hid behind a fallen table and waited for whoever is here to come down, it didn't take long before the smell of blood and bloodlust became stronger.

"Is anyone here? I can smell someone, but I can't see anyone," said a raspy voice, and a figure walked into the room.

The Fuck, who is that, no what is he? He doesn't feel like a human, and what's with the black dots? A dead apostle? No, as far as I know, he's too weak to be one. Well, better kill him before anything happens.

"Where are you, who are you, I know you're here," the demon said before a voice answered his question.

"Nice to meet you, NOW DIE". Three slashes later, there was a sword in the demon's stomach.

"Wow, what happened? Who is-", he didn't have time to say any more, before the sword began to slice upwards through the demon, splitting his head in two and falling to the dusty floor.

"It was easy, well, I wonder if there are others around? Could there be a Dead Apostle here? Is that why I'm here? Looks like I'm going on a Dead Apostle hunt".

"I, I WILL KILL YOU!". Izou quickly turned, and looked deadpan at the regenerating demon.

"So, I didn't harm your Spiritual Core. Huh, do you think that just because you can't die, that I can't kill you," after the assassin said that he stopped, as if he had realized how redundant his words were.

"What are you talking about, do you even understand what you are saying?".

"I have to say that I could have said it better, but the meaning is the same". Izou stood in one of the many sword fighting stances he has learned in his life. " Even if you can regenerate it doesn't mean I can't win, damn, it means I can slaughter you as many times as I want, ha ha ha!".

The arrogant laughter echoes through the abandoned house. The demon, who had dark brown hair and black dots all over his body under the tattered clothes.

"Er, what's talking…Ah, you're one of them Demon Slayer. In that case, I'll have to kill you". The demon's black dots turned red and out of the red dots came an equally red arm.

"Now screamed in horror at my Blood Demon Art! Massacre Arms!". The blood red extra arms stretched out, longer than any normal arm or lance. The six extra arms began to reach out quickly towards Izou

"The fuck?!" Ok, I didn't know he could do something like that, by the way he looks, I would have guessed he was a Ghoul, but he's more than that. What was they called after they were a Ghoul? Undead? I don't remember, but I can think about it after I kill it.

One step back and one slash the first arm was severed, one step forward and two slashes another arm was severed, two steps forward, and the Assassin took the other arm he severed and threw it at an arm who tried to reached for his left leg, the hand took the arm, and it stopped for a second, and the third and fourth arms could be slashed with one swing.

(Slash)

The demon watched in amazement as the human cut off its Massacre Arms and even used one of them to stop one of them, but the worst part was the smile that he had. It was a smile that he has had when playing with his food, that he has had just a few hours ago when he was chasing a young woman. It was unacceptable!

"Damn you! I am a demon, a hunter, an apex! How dare you have that smile while fighting me! I'm better than you, a fox to a rabbit!".

"Blah blah blah, you are just bark without a bite, if you think you are the apex here". Izou pointed his katana at him. "Come and take my life then".

The demon, as if to show that he has accepted Izou's challenge, stood on all fours and more of the blood red arms came out of the demon, and the severed arms grew back.

"I will kill you, Massacre Arms: Endless Ripping Rush!".

The red arms quickly reached out towards Izou and tried to ripp, hit and chop him at the same time. Those that missed Izou instead hit the house, taking down walls and ceilings where it landed. After the first 5 seconds of the attack, the entire room had been smashed and all of the demon's arms had been cut off, but only continued to attack with their stumps. Izou, on the other hand, had been hit by it on the leg, and now he was having a hard time holding his stance.

Fuck, I can still stand. Great, that means I can still fight, but how do I get closer to him? With the distance between us and the speed of his attacks, I can't get any closer. Well, if I can't come to him, he'll come to me.

"Hey, so the only thing you can do is throw your arms around like an angry child".

The demon's face crumpled up in anger, and along the line Izou had planned, the demon used his arms to launch himself at the assassin. The assassin, who hasn't had a serious fight in this life until now, moved a little slower than he had planned.

Izou jumped out the side and slashed with his sword at the demon, but was hit by the demon's shoulder and flew out of the house with it, it only took Izou a second to understand what has happened. He tried to jump up, but was stopped by a pain in his hand and arm.

"Shit!". My arm is broken, of course I was a little slower than I usually am. I've only fought weaklings, I'm rusty and when I get a serious fight, I get fucking hurt.

"You, you stupid.. human!".

Izou looked around and saw that the demon's body began to rise from the ground, minus its head. The head was a few feet away with one of his arms attached to it. "You, you don't use one of their katanas? Why, are you not one of them? Are you mocking me?"

"Er, katana? What do you mean by their katana?". What is he talking about? Is it the Church Burial Agency? No, I don't think there is one yet, an ancestor or a branch?

Izou couldn't ponder his words for long, before the demon sat its head on its body and prepared an attack. Before the blood red arms shot out att my Izou, he used a technique he took from an annoying Saber. It's not a sword technique, and from a Skill, but that won't stop him from doing it, even with his leg wound. Because in his words, "I'm agenius".

Reduced Earth

Izou's body couldn't do the technique decently, but it will do. Izou completely ducked the attack, confusing the demon. That gave Izou a chance to attack the demon again, he didn't use Reduced Earth, but it wasn't long before the assassin was on the demon. It tried to block the katana with one of its arms, but Izou had already figured out the best way to cut through it.

(Slash)

The attack cut off one of its arms, and 4 dots where the blood red arm came from. He had noticed that the extra arms come from the now red dots on its body, and cutting it off forces him to regenerate the dots first, and he regenerates more slowly.

"Heh, you regenerate slower, you start to run out of Magical Energy?", asked the assassin, realizing that the fight is coming to an end.

"Magical Energy? Are you mad; what are you talking about", spit out the demon. " If only I had more blood, I would drink from your body right now!".

Uh, blood…Oh yeah. He has to drink blood and gain his Magical Energy from it, not the best way for me, but it probably works better for him being a Ghoul, Undead or Vampire, Damn Alaya, or Gaia for not giving me information on my summoning.

A smile began to creep up on Izou's face as an idea came to him. "Hey, do you want some blood, because you can have some of my blood". The assassin showed his broken arm, and his leg covered in blood after he had done Reduced Earth.

The face of the demon reminded Izou of a child when it gets something it wishes for, the demon stretches its real arm towards the assassin's leg. "Thank you very much, thank you". Tears began to stream down his face, but before the demon could grab the assassin's leg, he heard a voice cut through the night.

"You can get it if you tell me where your master is". That made the demon stop, and his master's face appeared in his head.

I can't give the information about him, if I do, I will die.

Izou noticed the creature in front of him stop moving, in a cold sweat. Er, so he knows something, but it looks like he's scared, damn this is going to be tricky. Izou couldn't think about this for long before he noticed one of the demon's arms move.

(Slash)

The crimson arm didn't move fast enough and was severed, the demon jumped back, enough of its body regenerated to create more arms. The blood red arms carried the demon away like a spider with very long legs, Izou followed him as best he could with a damaged leg and a broken arm.

"Let me be, let me be, let me be, let me be!". The demon screamed, trying to flee towards the forest beyond the meadow.

"No chance in hell! I won't let you go until you tell me what I want to know, even if I have to cut your arms off a hundred times!"

The demon ran towards the wood, it wasn't that far away, if he could reach it he could get away from the strong human, but unfortunately the worst thing that could happen, happened, the sun started to rise.

The rays of the sun came over the mountains, and shone over the forest, creating a deadly area for him, if it wasn't for the shadows of the mountains, he would be dead where he stands, but there was only one place to take shelter, the house. But there was a problem, the human. But there was no choice, so the demon turned and charged at the human to attack with all his might. The two hunters of different times approached each other, when the human drew back his sword, it was then he saw it.

His death, his life, his life as Hiji Yamamoto. His family, friends, job, fiancee, and the day he ate her. How he had woken up, and met his master, and he didn't want to die. Hiji woke up in time to jump over the scary human, because for a moment he saw how he was going to die, that human can kill him, he doesn't know how, but he knows he can. The jump was so high that the human had no chance to stop him.

"Hay! The Fuck! Come down here!".

Hiji didn't, he just ran as fast as he could when he landed, it wasn't that far to the hous, but he wondered what he would do next.

Damn it all! If I go into the house, he'll just come after me, if I don't bring the house down on us, yes. I have enough strength to tear it down and regenerate, then I can get out when the sun has gone down, that's my only chance.

Hiji wasn't far away from the house, but when he was only a few meters away, he felt something, and he fell to the ground. After a few seconds of rolling around on the ground, Hiji noticed that there was a katana in his neck. A katana! No wait, is that a wakizashi?

"Damn, you're annoying, I had to copy Musashi, well that makes my job easier". The man came forward, sword in hand, and the sunlight behind him, like a god sent to kill him. A shadow covered the face, and made it impossible to see his eyes.

"No, please no". Hiji's blood red arms pulled him towards the house, his own body not moving because of the sword in his neck. The sunlight crept up against the house, burning Hiji's feet. Which made Hiji try to pull out the wakizashi out his neck, but before one of the blood red arms could, it was someone else who did it.

"Ho ho, what is this? You can't be in the sun? You really are a vampire." The face of the man was that of someone who enjoyed watching when someone else was in pain. "Hey, why don't we continue in the sun, the weather is so nice now, it's even stopped raining," with his words, he jerked Hiji towards the sunlight.

"No, no". Shit, I have almost no blood left, I can barely use my blood demon art, but I most. With that, Hiji sent out one of the blood-red arms to take the man's head, but it was cut off.

In horror, he orders the other arms to attack, but he gets no response. With a look around, he saw that all of his arms, even his body arms, had been cut off. "When did you?"

"That's what's so fun with fear, it can make you forget something important, so I'll ask you again". The sunlight from the sunrise hit one side of his face, the light reflecting from his eye, made it look like it was glowing red. And with his suffering, it was the human who looked more like a demon than the trembling demon.

"Ok ok! I will do anything, ask anything, just let me live!" And with those words, he sealed his fate, when a voice in his head spoke.

You have failed me, you are not only weak, but you broke my rules, thus your life and usefulness has expired.

Hiji Yamamoto didn't have time to reply, when his flesh began to melt off his bones, and then the bones started to melt as well.

"The fuck?!" Izou said, watching as the demon he questioned melted in front of him, and he realized. "Fuck, the Dead Apostle has a self-destruct button for his ghoul, or vampire, or whatever it is called".

The assassin looked around and then found what looked like a nice place on the grass to lay on. "I need to rest, I can find where the Dead Apostle is later, it's not like anyone else is hunting them". Okada Izou closed his eyes and sighed.

A few thousand meters away, in a small village, in a restaurant, someone was looking for a demon that had eaten people in the village.

"Delicious!"

One of the waitresses walked up to a man with yellow hair with red tips, the waitress asked with a drop of sweat on her forehead, "Is, is there anything else you want?"

The men turned to the waitress with eyes the same color as his hair. "Yes, can I get more udon, it is Delicious!".

Well, it will be fun to see them react to each other, and no, this is not at the mugen train movie. This is earlier, but you'll see when, when I continue with this one.

Remember to follow, favorite and review if you want me to continue this fanfic.

This fanfic idea came from the SpiritOfErebus stories Roasting People isn't a Fire Quirk, Dragons are just Bigger Swallows and A Reformer's Adventure in Perfectly Normal Historical Japan. But I started this one before I saw he had done the last one.

I would recommend checking out SpiritOfErebus and his stories.
