(Yo, Future Me here. I bit off more than I could chew mainly because of how busted this MC was going to be and that I'd have to write original and engaging plot which I don't have the skill to do. I could give the outline/plot points if requested but I don't think I'll ever pick this story back up. Enjoy if you can.)

This story, as you can imagine, will have a lot of OC elements, given the era. So, I will have a lot of free reign as long as I don't accidentally retcon anything.

The protagonist is not one of those evil-turns-good types, so if you hope or expect him to make a radical shift in mentality, then you'll be disappointed. This character, at his core, won't change all too much, but of course, a little change is inevitable.

I won't give any warnings, this is the Warring States Period of Naruto, and this story is rated M, you should know what to generally expect from that.

It will be brutal.

I'm creating this fiction since I have seen many Naruto fics that don't have this sort of character without it coming off as cringy or edgy for the sake of edge. This could be partly due to the villains of the story being understandable in their actions and background, or even being relatable.

This person isn't a good guy or a man who has to do bad things for the sake of the greater good. The protagonist is unapologetically a man who will do as he wants to get stronger.

I also don't want to give the impression that he is the type of villain twirling his mustache with a monocle type of ridiculousness. Sometimes he'll act very human, and the next, a ruthless monster out for blood.

I don't like author notes too much so here's the story.

"Talking" - Dialogue

'Thoughts' - Internal thoughts

Chapter 1

War System

"If you're here looking for closure, then I will have to say that I cannot give that to you. They were simply unlucky to have come across me. That's just how life goes." I craned my head down from a lying position to address the observers of my execution.

Their faces are as one can expect. Dismay at the lack of remorse or empathy in the face of death, veiled anger in the guise of twitching eyebrows or the curling of fingers into fists, and surprisingly, a few even had no reaction.

'Perhaps to not give me any satisfaction from my words?' My mouth twitches in amusement as my eyes are now looking at the ceiling. Some of the personnel in the room gave orders and a few seconds later, I felt cold but also a burning sensation from the injection site.

Blackness appear in the edges of my vision, whether that's from my eyes slowly closing or the coming death, I'm willing to bet on the latter since I feel my own heartbeat slowing.

'It has been a fun ride.' I mentally smile as I don't have the energy to do so physically. One would not think that the road to execution would be fun, but it was all due to an amalgamation of reasons.

My family died one after another; Nothing very traumatizing, but it was due to health complications. My mother and aunt were both smokers with the latter being a chain smoker. The former died from a heart attack due to obesity on top of unhealthy habits, with my aunt getting lung cancer. My Brother kept getting Pneumonia and, eventually, Leukemia taking his life a few years after my mother and aunt. I was 21 when it was just me.

My health was phenomenal and after losing both my mother and aunt, I hit the gym like no other to avoid such complications, but after my brother…I just gave up and decided to smoke to take the edge off.

Months went by as I worked a rather shitty cashier job being subjected to customer service which I wouldn't wish upon anybody. Jokes aside, everything changed after one night.

I purchased a gun when I became 21; For one, I was in America, and two, it never hurt to be cautious, so at 2:00am when I smoked the last of my pack watching the end of Naruto Shippuden that ended years ago, I walked up to my nearest convenience store two blocks away with my Glock-17.

Bought another two packs, and walked back to my house which had long been forgotten as a home.

What was surprising was that some dude was blocking my way when I was halfway there.

"H-Hand it over!" The would-be mugger demanded holding a compact knife about three feet away from me. Didn't seem very practical but he was shaking and stuttered a little so it must be his first time.

I didn't have the energy to ask him to specify as we both knew what he was talking about. Reaching into my pants pocket with my left hand, I tossed the wallet to him. Even though I had a gun on me, I just didn't feel the need.

There was no nervousness when being threatened, nor any emotion in losing my wallet.

He scrambled as my wallet impacted his chest and fell to the ground as he clumsily picked it up and ran the other way.

At this point I felt something come over me, when my family had died one after the other over the past few years, I felt hollow. Even though my brother died months ago, I felt nothing but emptiness when previously, while not the most emotional and outgoing, I still was lively and liked to have fun.

When that mugger was a few more feet away from me, the previous hollow and empty feeling was suddenly given an influx of anger and rage. Not at the mugger, at least only a part of it, but at my entire situation.

No career advancements, no family, no friends, no love interests.

No future.

So much hate and fury coursed through my whole body as I shuddered from the feeling, tears begin to fall from my face rapidly from the sheer overwhelming anger that I was feeling.

I didn't even hesitate when I slide my right arm out of my hoodie pocket and aimed it at the mugger.

"ACK?!" He grunted in surprise and pain while blood drips from his torso from the bullet.

Walking calmly, I made my way over as he struggled and screamed. My anger reached new heights as he crawled around and wailed pathetically, even if my rational side understood, but I wasn't in the most sound of mind.

"P-P-Please d-do-don't." He raised his arm at me when he managed to roll onto his back.

His response caused me to point my gun at him and pulled the trigger, over and over again until I heard a clicking noise indicating I had no more bullets for the very much dead human.

My misplaced anger and fury dissipated when I saw his blood pooling around him as dull eyes stared back at me. While some, or rather most, would feel horrific at the sight before them, I only felt relief and even a bit of pride.

This feeling scared me in the beginning, but it also excited me, at what else I was capable of. My state of emotional apathy was done and something else took its place. It wasn't anger or fury like I felt when I killed the nameless mugger, but it was something violent.

Many years went by after this night, or very early morning depending on how you look at it, and to the news outlets and people who still read the newspaper, a monster appeared.

Multiple murders across state lines quickly became a national story, but it later became a nightmare when weeks, months, and eventually years went by without the perpetrator being caught.

I made mistakes as I went along, and even almost got caught quite a few times, but I learned.

My final kill was in the same way as how I started, bullet to the back and turned over being shot multiple times more. That marked my 1,000th kill. I scribbled this poor schmuks name from his ID and walked to the largest police department in America. This is New York City and I made my final kill here even if it's not the only one from this place.

Walking up to the steps and waiting for the receptionist, I eventually got my turn which I decided to then do the wild act of stripping bare naked and calling myself, The American Butcher.

This was what everyone called me and I didn't bother to correct them since it's not like I only used a gun to kill. It would've been very boring otherwise. My Physique was crazy for a homeless serial killer, but I do a lot of armed burglaries as well for food and such.

At first, they thought I was some crazy lunatic pretending to be the most wanted criminal in America, as this wouldn't be the first time, but they would soon be in horror as they went through my belongings and found 1,000 names in my booklet.

Went to jail, and represented myself in trial, given that I had no intention of fighting a legal battle. I had many interviews with various reporters, psychologists, and journalists while answering them happily which unnerved them but that didn't matter to me.

They talked about reasons for killing all those people since I didn't target any demographic, but I did it because it felt satisfying and everyone should have a satisfying life.

I made sure nobody would ever forget me, and while this type of life wouldn't be what I had imagined in my teens, it was fulfilling in its own way.

As expected, I was guilty and executed.

'This life isn't what I had ever thought possible, but I'm glad I lived how I wanted to and achieved what I had set out to do: Be unforgettable.' The blackness fully enveloped my vision and I felt nothing at that moment.

I wonder what's next. Hell perhaps? If Christianity is to be true, then I'd burn in hell for all I had done, or reincarnation maybe? Or maybe even—

'Hmm? How am I still thinki—' I'm cut off by an impossibly deep and clear voice that seems to come from inside my head.

"This one will do." The being states and my eyes snap open to realize that I'm now standing barefooted with nothing on but I feel no chill or coldness from being exposed.

I breathe in only to smell a thick pungent smell of iron which I know all too well.

'Blood.' My eyes widen as I continue to observe my surroundings.

Blackish-red stones and rocks litter the area around me with dark liquid splattered everywhere which I assume to be blood from the poor lighting. I look up and the purplish-black sky barely registers in my mind from the impossibly large figure that seems to be hundreds or even thousands of meters tall, but as I examine closer, it seems to only be its head.

Glowing red eyes in a black skull with blood-red horns protruding out of its temples.

"You done mirin'?" The figure once again resounds in my head in such a serious tone despite the joke.

"Yes?" I respond in a similar but unsure way unknowing if this is some hellscape given the blood.

"This isn't hell." The skull responded and I blink in bewilderment, but I realize that this being could hear my thoughts. "You know, being referred to 'figure' or 'being' is rather demeaning."

I don't know how but I can feel that this funny guy is being sardonic.

"Well, am I supposed to know who you are?" I ask with a raised eyebrow still getting used to moving a bit after being imprisoned for so long, but not overly so to displease this person.

"At least you have some manners in that head of yours." He responds not even bothering to acknowledge my question and I can feel myself getting a little annoyed. Both at the lack of care for the situation and reading my mind.

"Can you not do that?" I couldn't help but blurt out that I almost immediately regret as his eyes somehow became a darker red and my surrounding began to shake from just his grumble.

"I could always send you to your rightful place, you should know where that is right?" He said in slight amusement.

I don't even bother to apologize since I would be dead…or rather somehow more dead than I already would be if this person wished for it.

"So what am I doing here?" I decide to get right to the point since he already said I'm not in hell and that's where I'd be going if not for his intervention, I'm guessing.

"Finally asking the right questions. Good. You've been chosen by me, The War God, to become my champion in a series of conquests." This god responds and I'm frankly stunned and confused.

This War God choosing me for…conquests? And why me? I was about to speak when I was cut off.

"You have shown qualities for being my champion, specifically the night of your first kill. All that emotion: Rage, anger, and hate. Typically, if you kept feeling that, you'd be chosen by the God of Hate or maybe even the Evil God, but instead it was a more violent tendency." This god explained but I still fail to understand.

"If that's the case then why wasn't I chosen by the God of Violence or something?" I can't help but wonder as he responds almost instantly.

"That concept is too vague. As you can imagine there are many gods. Primordial Gods such as Time, Space, Life, and Death aren't allowed to take champions along with Elemental Gods like Fire, Water, and so on. Only Concept Gods such as War, Hate, Sword, Love, Happiness…I could go on." He answered as my mind began to think of why and what the reason that these 'Concept Gods' chose champions.

"Alright, I suppose that sort of makes sense, but I've never been to war nor have faced many people at once. The most people I killed at once is 7, but that still doesn't seem right to be chosen by you. What am I supposed to—" I'm cut off once more.

"You will know in due time, but I've sensed it, so I've made no mistake. Champions are mortals that are selected by Concept Gods to participate in a tournament between the gods that wish to partake. There are naturally rules that have already been decided beforehand." He explained further and it sounds quite interesting.

"How do the champions compete then?" I ask as this sounds like it could be a lot of fun especially if someone like the God of War personally chose me.

"This time around, we have decided that the champions will accrue points by living and thriving within 3 Japanese animated series: Naruto, Dragon Ball, and One Piece. The order is up to the champion but depending on your feats, accomplishments, strength, and other factors, you will gain points which will be important when you have challenged all 3 worlds." He informed me accurately and precisely which made it easy to understand.

'Naruto, Dragon Ball, and One Piece, huh?' It's lucky that I watched these shows with Naruto being the one I'm most familiar with and One Piece being the least.

Before my death, I've seen quite a bit of the Boruto manga, and seen all of Dragon Ball including Super up to the Black Frieza reveal, but I haven't seen the new arc of One Piece after Wano.

Performance seems to be key here so while being safe and diligent could work, those who take risks would eventually come out should they not die. The good ol' risk and reward.

"Alright so what happens when I select one? Do I get to choose what time period I start in?" I inquire as that will be a crucial factor in determining what to do.
