He's the sun that will cast the shadow and darkness away.

(There won't be demons in this story... But the demons are always the ones with their darkest side shown...

This took place before and AFTER Storm King attacks Canterlot)

Rugen Solaris, a lost dragonet that's on a dark path of killing and bloodbath. No one really knew his past, as well as why he became what he is now. His real name may not be known all across the land of Equestria, but what his enemies called him... Petrifies them.

Hinokami.

(I used Rengoku as an example cuz I can't find anyone that's Demon Slayer related AND closest to a dragon.)

Prologue: The God of Fire and Blood

(I just love the intro)

The village lay in ruins, fire cracks as houses are being blown and burned, screams of the villagers can be heard all over the place. This village is once full of peaceful Abyssinians, and the view is absolutely beautiful... At least until they came.

It was a normal day for the Abyssinians, due to the fact that this village is located between the borders of Abyssinia and Equestria, many traders came for goods, making this town extremely wealthy and successful in economy. However, this attracted not only the traders and travelers, but also invaders. Over decades, many other tribes tried to take down this town, but failed to do so due to their strong army. The Abyssinians believed they're undefeatable...

Not until now.

They arrived so suddenly, the Abyssinian military never had time to react before the halt of the town was taken. When the Abyssinian army came, they found their town in ruins. As for their enemies, it's not like anything they've ever seen. They have more advanced technologies, strategic formations, and a dangerous commander.

They're known as the Storm Armed Force.

Their leader, a satyr whose name is Storm King, planned this attack for years, first he'll strike Abyssinia, then Mount Aris, lastly Canterlot; the capital city of Equestria. This horrifying slaughter is only the beginning.

The Storm creatures seemed to be enjoying this, they cheered in undefined languages, killing every Abyssinians they see off road, robbing their bits and food, the kittens were in their lists as well... The order was to strike terror down to the hearts of the Abyssinians.

In a corner of the street, three Storm Creatures found an Abyssinian mother and her child. The Kitten was crying loudly, the mother was begging for spares. However, before she could finish talking, her throat was slit open by one of the Storm Creatures, blood sprayed over the crying kitten. Then another flesh tearing noise, the crying stopped instantly.

The screams and cries stopped eventually, corpses and blood were like hills and rivers. Smell of rusting iron filled the air, and smoke could be seen even thousands of feet in the air and miles away. The Storm Creatures set up their campsite, and are soon asleep for tomorrow's bloody campaign.

At the entrance of the campsite, two Storm Guards stood, their muscular bodies gave away dangerous accents, however, after a long yawn was heard from them, the dangerous accent went away.

"&**@@)%#____&@#^@~?" (Why are we even doing this if there's nobody alive?) One of them grunted.

"*&^&#%&@$! &#^^#%, *^*@@!." (Quit complaining! If the commander heard this, we're done for!) The other guard glared at the first guard.

"**&**, ^*." (Okay! Chill the fuck off.)

Just as the two guards were arguing, a mysterious bipedal figure slowly appeared from the shadows behind the boulder. Making the two guards jump.

"&*^%#^#!!! *#*#&^*#))@^#!" (Cease approaching!!! State your identity and purpose!), one of the guards raised his spear.

The hooded figure did not say a word, instead, one of his eyes beamed in a creepy red color, before anyone could react, he leaped into the air and vanished.

"**&... &#^&%@?!" (Where the fuck is he?!)

"&#^*@&!" (Hell if I know!"

"&*#^---" Before one of the guards could finish cursing, the mysterious figure just... Teleported RIGHT BEHIND the cursing Storm Creature, on its right claw was a shining red blade, ready to be unleashed from its sheath.

The last thing the storm creature ever saw in his ugly life is the red, glowing eye of the figure, full of hatred. Then the storm creature's head was sent flying across the field.

Seeing the beheaded body of his teammate fell onto the ground, with blood spraying out from the nick, the other guard dropped his spear, legs shaking in enormous fear. The figure appeared again, this time, it aimed for the guard's lower body instead of the head.

Flesh torn, the guard stared in horror as his organs slid out slowly, then, he screamed in enormous pain. The scream was so painful and loud, the entire camp was woken by it. However, the figure did not seem to mind at all, it just stood there, staring at the screaming storm creature as if enjoying this.

By hearing the sound of troops approaching, the figure beheaded the storm creature, then turned around to face the storm creatures which had him surrounded. The figure slid his blade back into the sheath, however, his grip on the handle did not loosen.

The crowd of storm creatures suddenly made way for a tougher looking storm creature, the captain as it seemed; he had a sword on his shoulder, it was stained in blood.

"Creature!" The captain said in Equestrian, "You are brave enough to enter our territory, and slayed two of our brothers, now, face me in a stand-off so you die like a warrior!"

The figure did not move a single muscle, the air around them tensed up.

"YOU DARED TO IGNORE ME?!?!" The captain of the storm creatures roared in berserk, "THEN FACE THE PUNISHMENT!!!" He then raised his huge sword and ran toward the figure.

The hooded figure, however, stood its ground, the grip on its blade's handle tightened, if observing closely, jets of steam can be seen shooting out of the figure's mouth. Then, he spoke.

"Sun Breathing First Form..." The jets of steam became bursts of flame, his blade was lit up in bright golden yellow as well.

"Dancing Flash!" A single high-powered vertical flaming slash can be seen, the brightness blinding everyone, the captain stared in shock and fear, as the blade suddenly came up to his eyes...

After the light faded away, the storm creatures were horrified by the body of their captain; it was sliced, perfectly from down to top, in half, the smell of cooked flesh filled the air.

"*&@&!!!!" (KILL HIM!!!!)

It was chaos unleashed.

However, the figure still stood his ground, his steaming Nichirin Uchigatana glowed again, "Sun Breathing Second Form... Clear Blue Sky!"

The air seems to be heartened up to at least a hundred degrees, then, the figure's tachi slashed a perfect 360 degrees slash of flame. It's like a 2,000 pound Napalm, the flame erupted, along with the beheaded bodies of the storm creatures flying across the air.

The entire campsite was wiped out in less than ten minutes, after the slaughter ended, the figure slid the Uchigatana back, his hood were burnt down when he unleashed his attack earlier, exposing a young face of a dragonet around 14 or so. However, his expression when seeing all those beheaded bodies remained calm and cold, as if he had been doing this for a while.

"The demons... Get what they deserve..." He muttered before walking into the shadow and disappearing without a trace.

About an hour or so later, two Storm creatures scouts came back from the distance, their eyes widened in horror as the hell-like scene was displayed in front of them.

"*(&#)#&E&E..." (Holy shit...), one of them grabbed the other and ran quickly as he could, towards their other campsite, "*&&#%@))W^#! &#^&#... &*@&#&@!!!" (I'm getting the fuck outta here! My fucking god... It's the God of Fire and Blood!)

Little do they know, the figure which they called 'God of Fire and Blood', is standing on the peak of the boulder near the ruins of the town, staring coolly at the two escaping storm scouts.

"Soon..." he murmured.

Author's Note

There's the first chapter done! This is set in an alternative Equestria, so if any of my settings were incorrect, please don't mind because it's NOT supposed to be the same as before. As for the main protagonist's background and his breathing technique, I'll get into it later.

Until then!

Chapter 1: Storm Armed Force & Rugen Solaris

Storm Armed Force, now confirmed to be the biggest, the most dangerous, and most ruthless illegal armed force on planet Equis, is planning a huge conspiracy. Their goal of taking over Equestria is only one-fourth of their actual intention. However, their intention remained unknown for now, but from their attacking pattern and route, their targets were most likely to be countries and kingdoms that are outside the land of Equestria.

No one really knew how the Storm Armed Force was founded, nor any background of their leader and commander. Not even the EIUIA (Equis International Unified Intelligence Agency), the greatest and the most powerful intelligence agency could send any spies into the Storm Armed Force WITHOUT getting exposed the next day; the SAF (Storm Armed Force) seemed to have their own intelligence network, due to the fact that most of the high-class governmental agents were getting assassinated by the SAF. After the attempted assassination from SAF against Princess Luna failed, Princess Celestia immediately shut down the entire country; not even trade routes were opened.

The other kingdoms did the same after most of their high-class characters and agents were dead. Now, Equestria is a dead land.

SAF later confirmed as an international targeted terrorism force, what they did is far worse than anyone could possibly imagine; they slaughter every single living creature they see in their way, children, the sick, the old... As for the females; especially the ones in their teenage years and early adulthood... They were raped, then killed in an extremely painful and shameful way.

Wherever they go, fire burn down every structure, plus that their mass destructive weapon; hypersonic magic generated pulse cannon, which can easily wipe out a city that's big as Manehattan, as well as destroying mountains, which is a extremely dangerous threat to Canterlot; luckily, this destructive weapon takes nearly ten months to charge.

Currently, there's five popular and well-known commanders in the SAF, each of them strike fear into the deepest part of the locals' hearts. They're known as the Legion of Doom. (Since this is an alternative universe, I'll assign some antagonists as Storm King's followers. Since this is a bit related to Demon Slayer.)

The strongest, and the most dangerous among them all is Commander Grogar. This man with demon-like features made him the main leader other than Storm King in the entire SAF. Not only did his physical features terrify his enemies, but his skills as well. The staff of Sarcanas, owned by the Storm King himself, was given to Grogar as a reward after killing nearly 15 thousands enemies during his bloody campaign. Over the years, his staff absorbed a massive amount of magic which could easily kill the four princesses and every leader of Equestria.

The second commander, Tirek. A lost Centaur prince with ultimate urge of vengeance towards his father and brother, although it has been thousands of years. His ability is unique in its own way; to absorb other's magic and turn it into energy which he could easily reuse to create destructive beams. He never uses any physical weapons, relies mostly on magic, yet no one with magic can ever survive him; not in the history of Equis.

The Third Commander, Tempest Shadow, despite the fact of being in the third place in the SAF ranking, she's a total devil. There's this time when she led the SAF to take down a village with over 4,000 armed abyssinians with heavy weapons, the result was shellshocking; Tempest killed everyone, with the loss of almost every single member under her lead. Storm KIng was both impressed and unimpressed by this, as the result, Tempest's ranking went up to only third place. Which gave the spaces for her mind to have the idea to kill both Grogar and Tirek...

The fourth commander is Chrysalis, a changeling; used to be the queen of the most terrifying creatures in Equestria. However, after Starlight Glimmer reformed the rest of her hive, Chrysalis was abandoned and left alone to die. Hatred took over her as she later joined the SAf; just to take her revenge against Starlight Glimmer.

The fifth commander is rather a strange one; a Pegasus filly named Cozy Glow. BUt don't get fooled by her physical appearances, although with a young skin, she has the heart of an adult. Most of the strategic assaults that were unleashed throughout Equestria were all planned by herself. Although she doesn't have as many attacking skills as the rest of the commanders, IQ is her most dangerous weapon.

Under the five commanders and Storm KIng's lead, SAF haven't suffered a single defeat yet...

Until this record was broken by a SINGLE person...

Rugen Solaris.

The Solaris tribe is one of the most powerful groups of warriors on the land of Equestria, not even Yakyakistan can defeat them in battle. Not only the fact that they're dragons, but also that each of the tribe members has the ability to awaken strange marks on their foreheads which can boost their physical strength and their mental skills, making them the most dangerous and devastating warriors.
However, the warriors which awakened the marks suffered an ultimate backfire; unable to live past the age of 250 years. (I changed their settings here due to the fact that dragons can live for a REALLY long time. 250 years for them were the same as 25 years for a human.) As the marked warriors suddenly began to die out, a huge blank appeared in the tribe, which gave the chances for the SAF to attack.

The SAF wanted to take over the dragon land, and the biggest threat is the Solaris tribe, although they have less marked warriors than before, Storm King wasn't a risk-taker.

Finally, after two years of continuous warfare, the Solaris tribe was driven to extinction by the SAF...

Or so they thought.

His mother hid him in a secret spot in their cave, which the young drake watched as his mother was killed in front of his very own eyes by the SAF. At that moment, something inside him snapped. The drake doesn't remember much, but he was damn sure that he killed them.

He awakened the mark as well.

However, since his body is still a child, and that it's his first time using the mark, the drake was sent into a coma.

In his coma, his subconscious, he was visited by a rather strange uninvited guest. A creature claimed to be a human soul whom's name is... Yoriichi Tsugikuni.

The drake has no idea how it'd been in his subconscious, but in his long time stay with Yoriichi, he found out that this human swordsman is from another world full of flesh-eating creatures called 'Demons', and that the only way to kill them is to behead them with a special type of Uchigatana called 'Nichirin Sword'. And that combined with another special sword skills called 'Total Concentrate Breathing technique' , the user would be as powerful as the demons.

Over his time staying with the human swordsman, the drake, was trained and crushed by Yoriichi. Everytime he fails a test or any practice, Yoriichi would smack him with the tilt of his sword, "Remember who you are!"

Finally, after what felt like millions of years gone by training with Yoriichi, the drake, finally mastered the total concentrate breathing technique, which Yorrichi passed down; Sun Breathing. He was rather surprised by the fact that the drake completely took in his breathing form without any trouble.

Yoriichi, whom's soul is finally fading away after finding another successor of Sun Breathing other than Tanjirou, gave the drake his last gift...

Yoriichi's OWN Nichirin Uchigatana.

After the drake woke up, although he felt as if millions of years had gone by, in real-life, it's really just several seconds.

The little dragon, with his breathing technique and experiences, began to strike down the SAF one by one, slowly but sternly striking fear into their hearts.

At that moment, the drake died...

Rugen Solaris is reborn.

Chapter 2: Silverclaw

Rugen never liked crowded places, bars, and streets; it reminded him of that day his tribe was wiped out. However, to reach his second destination, he'd have to travel to Kludgetown for resupply. There he heard an Abyssinian named Capper who can help him with a personal need. Although the day in the Badland desert can be torture, Rugen really doubts he won't make it, Yoriichi's training is the REAL torture. Using the breathing technique, he fastened his steps and saved most of his stamina. At this rate, he should be able to make it to Kludgetown by noon.

Badland's natural habitat gave birth to many deadly traps, such as hidden quicksands, a cobra, or rattlesnake in disguise, dust storm, and some bandits; Although the last on the list isn't much trouble for Rugen. Along his way, a few bandits were stupid enough to rob him, with their blood spilled in the heated sands, quickly rotted and dried into mummies. Rugen, after he ate numerous snakes and scorpions for snacks, skipped a few quicksands, and beheaded some bandits, finally arrived at Kludgetown; although the troubles did slow him a bit.

It was near evening, the street had fewer creatures, yet the bars and other clubs were still crowded. Rugen's strange features did attract some unwanted attention, but they're clever enough to stay out of trouble at the sight of Rugen's blood-red Nichirin Tachi.

Rugen had a hood on, instead of the traditional samurai armour on, he has a Ronin cloth on to keep himself off sight, although it helped little when it comes to attracting attention. By the time he arrived near an ally, the Ronin hard a terrified scream of a young female. frowning, he turned to spot a few unknown species creatures cornering a female Abyssinian; the girl is around 15, although at such young age, her body structure and sizes are extremely attracting; which is considered dangerous in those places. Males knew what's happening to her.

The gangster members, each with lewd smiles on their ugly fish-like faces, the leader glared at his subordinate forcing them to back off as he returned his lewd look, his fins-like claws reaching for the young girl's oversized chest. The Abyssinian closed her eyes hopelessly.

Suddenly, a quick red-flash along with the sound of metal screeching and flesh tearing, the gangster leader's claws were cut off.

"ARRRGH! WHAT THE BUCK??!?!" The leader screamed in agony, the other members did not expect such sudden encounter, a few more red-flashes and each of them received deep blade cuts; one of them even got his guts flew out. It has only been less than ten seconds, and there's no survivors. The Abyssinian girl was beyond shocked, she heard a grunt as the leader trying to crawl away from the bloody scene, then, a wakizashi came flying towards the leader, stabbing him straight into his head, killing him instantly.

The Abyssinian girl saw the one who destroyed the gang, it was a...

"You know," the mysterious hooded figure said in a low voice, "it's difficult to stay clean if you're not wearing your clothes right." He then tossed her a clean pair of clothes. Then he sheathed his blade, turning to walk away.

"W-Wait!" The Abyssinian girl cried out, "Who are you?"

The Ronin stopped, his head tilted slightly, "Just a regular swordsman looking for someone."

"You don't fit the word regular though." the Abyssinian reply as she wore her clothes, years of witnessing scenes like this made her calm.

The Ronin was silenced for a moment, "Go now."

"No."

"Don't make me use the extreme way."

"You wouldn't."

The Ronin sighed fustratingly, she's right, teaching of Yoriichi told him not to harm the unarmed ones with zero intentions of evil.

"Fine, what do you want?" The Abyssinian girl smiled.

"I'm Silverclaw, and..." she looked firm, "I want to learn sword arts."

Rugen eyed her seriously, "Think twice Silverclaw, a swordsman is not about killings only, it's... Complicated."

"I don't need to think twice," Seeing Rugen walking away, Silverclaw grabbed his arm, making the Ronin's muscles tensed up, nearly holding the verge of slicing her.

"Let. Go." Rugen said, the air around them tensed up, seeing the murderous look on Rugen's face, the Abyssinian girl yelped and immediately let go, "That's what I thought."

"Please! You have to teach me!" Silverclaw cried out desperately.

"And the reason?" Rugen sighed, another fact about not to get involved with females.

"M-my family," Silverclaw began, "they were killed by the SAF." Rugen sighed, another victim, he had already saw too much of those victims, but next thing he heard made him reconsidered his previous decision, "Not only myfamily, my entire clan... None of them survived... My father hid me in the underground storage... When I came out..." Already Silverclaw's eyes were filled with tears and hatred.

Rugen had a complicated expression on his face, it'd be too cruel to just abandon this lost girl here, but she'd be his weak spot from now on... And one of the most dangerous things about a Ronin is a weak spot; she could get used on him. Yoriichi's words came into his mind, "My sun breathing successors were less than I'd expected, please Rugen, if you could find anyone in this world who are willing to learn the breathing technique, teach them like how I taught you."

Silverclaw had her head low, so, I'm abandoned once again...

She felt a warm palm on her head, then it was the voice of angel, "Stay close."

Her face was erupted with a cheerful smile, "Thank you! You're my savior!" Her smile was so perfect, except for the blood still on her face, other than that she's an absolute beauty...

Some unspeakable thoughts came into his mind as Rugen blushed slightly, shaking the thoughts off as he held into Silverclaw, the sensation of their bodies touching made the girl blush, "You won't be alone from now on." Rugen said, "So will I."

Unknowing to himself, those word finally broke the last barrier of her heart, she couldn't hold it back anymore, now over his shoulder, she wept with all her will. Crying herself inside-out.

Rugen wasn't expecting this, the attracted creatures backed off from his gaze, it seemed almost like they're to only two alive in this world, he sighed and gently scratched her ears.

The crying stopped instantly, Silverclaw's face turned bright red, feeling the sensation from her ears, she purred softly.

"A-are you feeling well?" Rugen staggered, he may be an expert at combat, but a total loser in figuring out a girl's feeling.

"Of course," Silverclaw purred, her eyes closed and her head lied on Rugen's shoulder comfortablely, "can you keep scratching my ears."

"U-uh..."

Silverclaw pinched the spot around his waist, Rugen flinched in the sharp feeling, "Okay! Okay!" And he kept the scratching on.

Later, with an asleep Silverclaw in his arms, Rugen stopped by a building which seemed almost like a den, he knocked on the door, as he was waiting for the reply, Rugen couldn't help but wondered about his future.

Well, maybe I needed someone to be with after all, His soft gaze on Silverclaw's sleeping figure, she's quite cute when asleep to be honest...

The door opened, Rugen immediately left his gaze on Silverclaw, seeing a slight brown colored male abyssinian with a paiur of green eyes, Rugen relaxed.

"So, are you Capper?"

Author's Note

I watched Zatoichi, a badass he is. Although he's a blind old man.

Which is another reason why Rugen's a badass...
