Alright, i've gotten back into the Campione! series of light novels so I thought "hey, I should make a fanfic about this" which then led to this. This is my attempt at throwing an OC into the Campione! mix for absolutely no reason. Enjoy.

Sorry forgot to edit when I posted it, fixed now.

Finally spell-checked. Edited once more.

Chapter 1: Noble Monster

Third person - Point of view

At the start of our story, at this moment in time. There are no stars in the sky. For they have been extinguished by the heretic god Athena. Who, moments ago, had retrieved the final piece of her self. The Gorgoneion.

In one of the many different parallels of this world, Mariya Yuri would be standing in front of her. Having breathed in the essence of death created as Athena recovered her power. But, in our story, her place is taken by a boy appearing to be the same age.

A boy with short, messy, brown hair and wearing a regular school uniform with a sword on his back. A boy, that managed to carry Mariya away from the cloud of death before returning to that spot in the blink of an eye.

A boy, with eyes glowing crimson, each bearing a cross made of runes.

As the boy reached up to his sword, Athena spoke. With a small, excited smile.

"What art thou that surpasses human limits unassisted?"

The boy unsheathed his sword, showing its full length to be near his full height, yet holding it as though it were half its length. Then answered.

"Do you really want an answer? Wouldn't it be more fun to find out the hard way?"

His answer only made Athena's smile grow wider, "yes, thou will make a fine distraction till the god slayer arrives."

This prompted him to smile, wide and invitingly, "or perhaps I'll be the main event."

Before he had the chance to charge, a small gust of wind blew, and a moment later a voice stopped his movement.

"Theron?"

The boy now named as Theron looked incredibly annoyed at the interruption, but nonetheless turned to answer, as the light in his eyes disappeared. "Yo, Godou. Sorry, but I'm gonna have to take a crack at Athena first."

To most, that statement was absurd. Only a Campione could stand against gods. Any others that would try are doomed to die. But, most people forget. They forget, that all Campione were once human.

Kusanagi Godou - Point of view

This wasn't good. I'd been summoned by Mariya using one of my authorities only to see a classmate wielding a massive sword insisting on fighting a god. Why does this stuff always happen to me?

"Uh Theron, it's my job to take care of this. I am after all the only Campione here. I don't think you can handle this."

I really wanted him to back down, there was no way he could win. Then again I didn't really know anything about him. Come to think of it, how can he even see Athena?

"Sure, you're more qualified Godou, but I'm not going to destroy any national treasures while I'm fighting am I?"

Theron's smile took on a mocking look as he said that. That was really a low blow. I don't intentionally destroy landmarks, it just sort of happens.

"Are you saying you can actually fight a god?" Was my cautious and semi-optimistic response.

"Fight? Sure. Win? I don't really know. But I'm going to find out." Theron's mile shifted once more from mocking to predatory.

The next person to speak up was, oddly enough, Athena. "Thou possesses the spirit of a warrior. It would be disrespectful to keep him from battle, and I am inclined to test myself before facing the godslayer."

This seemed to be just what Theron was waiting for as he hastily called out "looks like you're outvoted!" before charging at Athena. Eyes now glowing.

I wouldn't really call it a charge though, even to my enhanced senses he was difficult to track. It was absurd, there was no way he could be a normal person with speed like that. I had known him for over a year so I knew he wasn't a Campione or anything similar, so what was he? And why were his eyes glowing?

Theron Safir - Point of view

Godou's interruption was rather annoying, but largely irrelevant. If Godou were to fight, he would undoubtedly cause a massive amount of collateral damage. Like that time in Rome were he crushed a Colisseum in a sparring match against his knight. That meant it was up to me. It didn't hurt that I was curious about whether or not I could fight on even terms with a god.

Still, no time for distractions. Athena was momentarily taken off guard by my charge but she was countering now. With black waves of death... What a pain.

I slashed the first in two with my beautiful silver claymore, dodged the next two and continued advancing. Blocked the next, slashed another, never letting them touch me. My instincts said that would be bad.

It was a good job she wasn't used to that power yet, or I may have had to contend with a fog of the stuff. Nevertheless the rain of black magic continued, slowing my advance but not entirely stopping it.

It took three minutes to advance a little over a hundred meters. But that left me within ten meters of Athena. So far I was unimpressed.

Then the ground starting rumbling, and my instincts urged me to retreat. Which I did, avoiding being eaten by a giant snake which erupted from the ground with Athena now standing atop it.

Athena chose this break in the battle to speak "To advance such a distance so quickly, thou contains the potential to become another child of Pandora. What is thy name warrior?"

"Theron Safir" was my swift response, followed by another charge.

"This one shall remember thy name warrior. A pity thou has chosen to face this one, for thou could have been a most prized disciple." were the last words spoken before Athena urged the snake to attack.

As its head came crashing towards me, I did not falter. If I slowed it would change direction to attack me. If I attempted to evade it Athena could rain more black bolts on me so I wouldn't be able to approach. She could probably do that with what I was planning anyway, but my idea sounded much more fun.

So, as the snake was about to close in on me, scarcely ten meters from me, I leapt up. And landed on the head of the snake. Far from being surprised, Athena looked excited, and of course proceeded to fire more black magic at me even as she created a scythe for the inevitable sword fight. As before I practically waded through the magic, dodging what I could not block or sever, even as the snake writhed underneath me attempting to dismount me.

But I would not be removed so easily and managed to maintain my balance, even as I closed to swing my blade at Athena.

Seeing the ineffectiveness of her attacks Athena parried my sword with her scythe, attempting to knock me off-balance so I could be tossed from the snake. But it was clear that while Athena was a master of combat, her specialty was not close quarters.

As I swung my blade time and time again I stubbornly refused to back down or be tossed off of the snake, forcing Athena further back even as she parried and blocked each of my swings. Each attack she managed to make was incredible, perfectly aimed to kill at the weakest point in my guard, but I was just too fast for her to cause any serious damage.

However through the battle I and my opponent had accumulated a number of non serious wounds. The worst of which being severed tendons in the wrist for Athena, who somehow continued on unhindered. Gods really were absurd. And through it all, my blade became darker, I began to feel a familiar tug coming from it but pushed it to the back of my mind.

I sensed, rather than saw Athena's next move. And leapt off the snake. Just in time to avoid a burst of black fog now surrounding Athena. Guess I really would have to deal with that fog. Dammit.

"Thou art skilled indeed to force me to use such measures. How will thou fare when thou cannot advance though?" I gave a grim smile in response and began my preparations, even as the snake reared its head back. I raised my right arm above my head and twirled it in a small circle.

"I offer up this contract to bear the wicked spirit beast that dwells within the atmosphere"

Red rings made of glyphs dropped from above my arm down to the floor, expanding to fit me inside of them before disappearing into the floor, leaving my body glowing slightly. My grin became less feral, and more controlled as I allowed the snake to close even closer than before. then I disappeared. Reappearing back on it's head.

Well, to Godou and his companions I disappeared. I wasn't confident that Athena couldn't track me, but I was more or less certain she couldn't match me. Now, the dangerous part. I had to run straight through that fog, which I couldn't see through mind you, and make my attack before getting out of there. Without breathing any of it in. What a pain. I decided to start my attack, and ended up losing my balance as I entered the cloud. That caused me to fall off of the snake. That in turn made me decide to kill that damn snake.

I hastily stood and turned to see the snake with its head reared back to lunge once more. Why was she using the same attack over and over again, did she not have control over the snake? Well it didn't really matter. The snake was going to die now. I raised my blade over my head. It was Almost completely black save for the hilt and cross guard. It had feasted on the residual emotions of the battle. But it wouldn't be enough.

My blade was not a normal blade, where I am from it was called Clarent. The traitors blade. A hero relic befitting of its title. The blade feasts on all negative emotions, despair, rage, hatred, envy and many others. But when activated, it gradually converts the users own emotions to power and replaces them with negative emotion. Many wielders had thus turned traitor to their armies and slaughtered them. How the blade came to be mine is another story, but I was about to show why it was feared.

As I reached out with my mind to the sword, the blade erupted in thick crimson energy which seemed to wrap around the blade, even as it shifted to a more demonic looking form. The snake was closing now, it would be a contest between my strength and Athena's authority.

I could feel everything good leaving me, I could feel pure blood lust replacing it. And I knew I needed to make my move quickly. With the speed of my spell, and the strength of my blade, I swung down at the last possible second. And for but a moment, my blade was stopped by the impossibly strong scales of the servant. Then my blade pierced its mouth and proceeded to bisect the entire snake with a flash of red light running down the length of the snake, dismounting Athena in a rather violent manner.

Wasting no time, I moved to intercept her as she landed on the ground. Guessing where her position was through the black fog I rushed through. Intending to cleave her in two as I did the snake, instead I merely cut through her side. Gods being tougher than their creations, she was wounded but not defeated. In turn, she had carved a jagged line across my left arm. I barely noticed. My blade had dulled all sense of pain. As I exited the black fog I turned, to see it dissipating. The injury I had dealt had probably weakened her enough to force her to stop.

Upon seeing her again a single realisation pierced my veil of blood lust. "Ah, my strike somehow sealed that aspect back into the Gorgoneion. Or maybe it simply happened because of the damage."

Of course Athena was not amused any longer. "Thou. Thou cannot be human. This one cannot be bested in such a manner by any mere human. I ask of you again. What is thou?"

Given my current state of mind, it was surprising enough that I understood the question. Even more surprising is that I managed to respond in a growl like voice. "Something between a man and a monster." Then I once more charged. All reason abandoned.

Athena, despite carrying what would normally be a fatal wound, still managed to erect a defense. She summoned up a shield vaguely reminiscent of the form of the Gorgoneion. But it was for naught. The longer Clarent is active for, the stronger it , even one-handed I had the strength to cleave through the shield easily, creating a long but shallow cut from her right hip to her left shoulder. The force of the blow knocking her back off of her feet. And removing the Gorgoneion from her. Reverting her to a child-like form.

For a while I stood there. Trying to reign in control of my blood lust enough to sheath the damned sword. As Athena shakily stood. I managed to at least seal the sword once more, yet the effects remained. "To be bested by one such as thou, perhaps tis not so humiliating. You may deliver the final blow, as is the victors right." She stood there calmly as she invited her own death. And I slowly walked the few feet between us. Raising my pitch black blade above my shoulder with my one good arm. And tapped her between the eyes with the hilt.

I am a little embarrassed to say that her surprised expression was rather cute. Then again despite being a goddess of wisdom as well as one of life and death and whatever else there was. She still looked like a little girl right now. Albeit a little girl who was severely beaten and injured, but I was referring to her face.

"Then, as the victor. I'll take what I was meant to be guarding." I turned around and walked, or rather limped because I had at some point injured my leg. Over to where the Gorgoneion was. Then knelt to pick it up.

"Honestly, I don't see what the big deal is with this thing." I straightened up as I stood and turned back to Athena. "I have no quarrel with you, I just wanted to stop that guy" I pointed towards Godou "from breaking anything. The best way to do that was to get you to stop bugging him and his friends. So I'll hold onto this until I find someone better to hold keep it."

"So rather than take this ones life you shall take a piece of this ones divinity? An unusual exchange when thou could take both." She looked rather cute when puzzled too. Dammit. I had to stop thinking that, she's thousands of years old and looks like a little girl for crying out loud!

"Oh? This belongs to you in the first place? In that case you may keep it, though I would ask that you not cause any unnecessary trouble with such a thing." I held the artifact out to Athena expecting her to take it, to my surprise though she smiled and told me "thou art a strange man Theron Safir, I shall leave the snake with you so that we may meet once more." And with that, she disappeared.

That left me alone with Godou's group, and a lot of pent-up aggression.

At that moment a feminine voice spoke from a short distance behind me. "Well that didn't go as planned, though I must say I never expected you to be such a fool."

That last comment made my eye twitch. It didn't help that I didn't have many favourable encounters with that witch. As I turned I feebly hoped that I was hallucinating. But, no. It was definitely Erica Blandelli behind me. I put on my best scowl and stared at the exotic beauty. Hoping she would spontaneously combust before I decided to start an incident with her order of knights.

"That was the perfect opportunity for you to kill a goddess and usurp her authorities for yourself. Hm, but I guess a fool such as yourself didn't realise such a thing."

I didn't understand her at all. She was pleasant to everyone but me. Why me!?

I slowly felt my hand reaching up towards my sword and shifted my scowl into a smile. Not a kind smile by any stretch of the imagination. A 'I want to kill you and the only thing holding me back is this smile' smile. "Erica." I stated. "Yes, oh foolish one?" Okay, that was the final straw. "Hold still for a moment please." As soon as I finished my response I took a step forward and unsheathed my blade, bringing it down in the same movement in an attempt to silence that insufferable voice. Of course given the state of my left arm and leg, plus the fact I didn't really want to kill her, yet, she was easily able to leap back out of my reach. And I of course fell over. Damn I hate that woman.

"My, my, foolish, aggressive and clumsy. What a barbarian." I would so kill her if she was a few feet closer.

"Erm, Erica maybe you shouldn't antagonise Theron, he doesn't look very good at the moment." Despite the fact that Mariya's voice was a welcome addition, I felt obliged to point out that "I'm fine" despite the fact I absolutely wasn't. As I was struggling between my pride and health a familiar and dreaded voice spoke within my mind. "Go on, you know what you want to do, consume everything. Drink their blood, devour their bodies, feast on their souls. You know what to do." A chilling laugh echoed in my mind as I rebelled against that infernal instinct. It was something all those with my eyes was plagued by. Though many treat that voice as though it were a god, to me it was naught but a demon.

I managed to shake off the voice before anyone noticed, and just in time as another voice spoke out."Hmmm are you sure? It looks like you might bleed to death if we leave you." Dammit, I'm starting to dislike him too. Amakasu Touma. The guy was like a ninja, and had an unreadable expression. Not blank, he was just ALWAYS smiling. And perceptive enough to notice I was likely dying. Dammit.

Erica of course wouldn't leave this alone. "Hmmm, it looks like you're right. So, Theron. I'll help you out this once, and you'll owe me a favour later. Okay?" I really hated that sickly sweet voice she uses. Of course there was only one response to that offer. "I refuse." Never would I accept being indebted to her of all people.

The next person to speak out was Godou "woah, hey you'll die at this rate right? I'm sure Erica's joking" "I'm not" "er, well I'm sure it won't be that bad a favour right?" "It will be." "Ah, then, I think you might have made a good decision. We'll try to get you to a hospital." Wow, I didn't even have to try to convince him. Then again, he knows Erica better than me, so he probably already knew it would be ridiculous to owe someone like her a favour.

"Oh, and how exactly do you intend to explain those injuries? I'm sure the police will take an interest in this." Of course Erica had some way to derail that plan. And of course I was getting light-headed. I should've really bandaged these wounds already.

Of course, out of the blue came a sympathetic voice. One that we'd all completely forgotten about since she disappeared early on. "I can understand your reluctance to accept such a trade with that woman. So allow me to heal you instead." I turned to see a girl appearing to be the same age as Erica on top of a small shrine looking down at us, a moment later she jumped down and landed near me.

Erica seemed familiar with her as she turned her attention to the newcomer, "Oh? Still here Liliana? I thought you had already left. Don't you have to run along back to your master?" The newly named Liliana scowled slightly at Erica before answering while facing me "my master was interested in the heretic god Athena, since she was defeated he will no doubt be interested in the one who defeated her. So it would do no good for him to die here."

Accepting her reasoning I allowed her to perform basic healing on my injuries, for a moment I was worried that she would realise my 'unique' nature when her healing spell didn't work as expected. As opposed to the green light from her hands healing the wounds it was over, it seemed to be absorbed by my body and used to heal all of my wounds simultaneously. In response to her questioning look I merely responded, "don't worry about it, that's normal for me." Fortunately that seemed to be enough for her as she continued to heal enough to close my wounds but not enough that I would be completely fine. "My thanks Ms. Liliana. I may have been in a terrible situation if you hadn't shown up." That brought an almost imperceptible smile to her face as she responded "yes, it would be quite terrible to be indebted to that one." Without another word she left.

Leaving me with Godou and company once more. I really wanted to leave, but I would need a while to rest enough to get home. Which left me open for questioning. Erica of course was the first to speak, "why did you not slay Athena when you had the chance?"

I turned to her, and the words rolled off my lips with barely a thought "Why would I need more power?"

My answer however seemed only to confuse her more, before she could ask any further questions I interrupted her. "Yes, I know what a Campione is.

Campione – Godslayer – is the supreme ruler.

Since he can kill a celestial being, he can therefore call on the highly divine powers held by the gods.

Campione – Godslayer – is a lord.

Since the power to kill a deity is in their hands, they therefore have the power to dominate the mortals on Earth.

Campione – Godslayer – is a devil.

Therefore of the entire humanity living on earth, those who have the power to oppose them do not exist!

That is what everyone says a Campione when asked at least, but what do I need for such a title? Things are much more interesting when the odds are stacked against you. Besides, I've been called a devil before. I'd rather not have it as an official title."

Godou at least, seemed to understand. Mariya looked a little confused but didn't really push the matter. Erica had her mouth hanging open. It was worth passing up the power that comes from slaying a god just to see that. And Amakasu? he was just smiling. Of course.

I heard a heavy sigh from Erica as she recovered from her shock, and wasn't surprised at her first words. "You really are an idiot." It didn't lessen my twitch at all even if I was expecting it. But it helped to curb my natural instinct to start slashing. Which reminded me that I still had my sword out, so I reluctantly sheathed it.

As I tried to move my legs I noticed I had full movement returned to me. "Well as pleasant as this is, I really need to go home. You all know where to find me." With that I took off, I would like to say at a steady pace, but I was still limping.

It was going to be a long walk home.

End of Chapter One

Alrighty, I think that came out pretty well. I'm gonna make a start on chapter two immediately. Any thoughts or comments, review and let me know. As for Theron beating Athena, take a look at legend of the legendary heroes and watch Tiir in the later episodes. He has similar abilities to Theron and the speed he moves at the first time you see him is ridiculous, he literally kills armys.
