Dark Exorcist

Part 1 (2)

"Kunai spiritual explosion!" Zenra threw his knife full force, this time aimed at the creature itself instead of the street. The moment it made contact, a fierce shockwave of power and light filled the streets as Naiomi was blinded and pushed back. Kasuke tried to keep his eyes open but the light was too much. After about 15 seconds the light finally faded.

Zenra walked towards the flames that engulfed the area. At that moment, the demon lunged out from the flames, it's face severely burned off as it punched the exorcist with overwhelming force. The team member spat out blood with wide eyes as he was launched back, crashing through a large window of a building behind them.

"Zenra!" Kasuke cried out when the demon set it's sights upon him. It grinned revealing it's razor-sharp teeth before jumping into the air, going right for him. Just then a red sphere of spiritual energy came out of nowhere, hitting the demon from behind in a powerful eruption of red light. That's when Kasuke looked up to see the monster covered in bruises with their captain standing between him and the demon.

"Sorry I left you all alone, I'm here know"

"Captain! You're back!" Kasuke said with a surprised expression. The exorcist told him to get Naiomi and stay by Zenra while he delt with the demon. "Y-yes sir" The C-rank exorcist rushed over to Naiomi who was just getting up from getting pushed back from the explosion from before. "Captain ordered us to stay back" Mashida told her as they both made their way over to the shattered window where Zenra had landed. The exorcist was still out cold laying in the middle of the store's carpeted floor.

The captain made quick motions with his index and middle finger as red shapes made of his energy formed in front of him as if drawing in mid-air. He made an "X" in the center of a square before aiming his hand towards it and his target. "Secret art: Cube of entrapment!" The symbol broke into wisps of red light before reforming around the demon trapping him within a transparent red cube of spiritual energy.

The demon began striking the walls of the prison struggling to escape with no luck. With a hand motion towards the dark sky, the cube was launched into the air at incredible speed. "Explode!" Clinching his fist, the prison erupted in a burst of energy utterly destroying the creature leaving nothing left as red wisps like stars floated down upon the area.

Both C-rank exorcist could do nothing but stare in amazement at the power of their leader. (H-he beat that monster like it was nothing, even Zenra could barely do anything against the monster. Seems he's not as strong as he thinks he is) Mashida thought just as their captain walked over to them.

"Glad to see you both are ok, sorry I took so long, I could feel faint traces of dark spiritual energy but I assume it was a trick to distract me while that devil attacked you. Luckily thanks to Kinchin's powerful energy attacks, I could tell it wasn't a mere demon he was faced with. Let's head back so you both can finally get some well-deserved rest"

The next day...

Kasuke awoke to silence, this surprised him since he expected to be woke up early in the morning. He looked at the clock on the wall that read: "12:00 Pm" Rubbing his eyes he walked out into the hall where he saw a uniform folded by his door. The exorcist picked it up walking a few doors down to the bathroom to shower. He took a deep breath as the warm water ran down his face. Kasuke was average but had a little muscle on him.

After the shower he put on his new uniform admiring it in the mirror. He smirked before making his way outside in the large green field nearby where Naiomi was waiting for him along with their leader. "Welcome back Kasuke, now that you're both rested, I can finally formally introduce myself, my name is Asura Shigatomi. I will be your captain of unit two. Today we shall be training to see how you are as an exorcist and see what your strengths are and what you need to work on"

"How exactly will you be testing us sir?" Naiomi asked with her hands in a formal position. At her chest. Asura answered: "Like this" He gripped his left arm with his right, "Dark art: Demonic summon" in a flash of red light, a six-foot demon made of rock manifested beside him. The pair took a step back in fear.

"Don't worry, this demon only follows my orders so it won't attack unless I command it to. Now then, your first test is to see how you both react in a fight, I'm sure Zenra did most of the fighting against the high-rank demon, now it's time for you both to fight. Just because this is training, doesn't mean I'll hold back. Go demon!"

The pair prepared themselves as the summoned demon lunged toward them throwing a punch aimed for Mashida. The young ninja evaded the attack at the last second as the creature staggered past him before turning back around. It put it's palms close together as a purple sphere formed between them. Both were unsure what to do when the rock demon threw it right for Kasuke like a baseball. Without thinking he crossed his arms in a blocking position as the projectile hit him head-on, bursting on impact.

He slid back a few feet with burns and scratches on his arms but didn't take as much damage as he expected. "This creature isn't as strong as normal demons"

"That's because I didn't put much spiritual energy into the summon. The more I flow into the creature the more dangerous it becomes. Observe" The man pointed his index finger toward his summon as his body lit up with his red aura as sparkles of red energy flowed into the demon. It grew bigger and more buff as it's purple aura and eyes grew red and brighter. "If I'm correct I've transferred 30% of my spiritual energy into it's core. Let's see how you fare against it now"

Asura stood still with his arms crossed as his summon, now seven feet and more intimidating stomped towards them once more, this time engulfing it's rock fist in a red fire-like aura throwing a punch straight for Naiomi. The female exorcist pulled out a small dagger, throwing it right for the center of the monster's head but watched as it broke on contact before hitting the ground.

"That thing only has 30% of our leader's energy flowing within it yet a dagger can't do anything already!? Fine! I have a trick up my sleeve. She got on one knee slapping her palm onto the grass. "Secret art: Plant configuration!" All watched as large roots rose up from the ground, wrapping itself around the demon's arms and torso keeping him in place.

She smirked advancing toward her foe, throwing her foot down with a powerful kick to the summons's forehead. She landed beside Kasuke as they saw a small c***k form in the center. "Sigh, you got to be kidding me, all that and it only made a mere c***k!?"

"Come now, surely you both have more power than that. I'll give you credit for your strategy Naiomi, but if you both don't put more effort into your attacks you won't get any further than this" That's when Kasuke had an idea. He took a deep breath, feeling his spiritual energy flowing throughout his body. He went for a head-on attack as a demonic aura engulfed his fist, striking the summons's skull with immense power. Both Asura and Naiomi watched as the still-bound creature cracked apart before falling to pieces.

They looked at him in shock before their leader responded: "Hmm, good seems you have some real potential. Now for the 2nd test. This one focuses on speed" Their leader formed a small but powerful sphere of red energy above his index finger. "You'll need to catch this energy sphere. Let's see what you both got"

(Heh, this should be no trouble for you) a voice responded. (W-who's there!?) Just then he found himself back inside the black void with the demon king sitting on his throne. "You little s**t, how dare you forget about me already! If I could I'd burn you to ash where you stand! However, you're the only body I can hope to achieve my goal with so I'll have to make do with you"

"Wait, where were you when I was being attacked by that high-threat devil!?"

"I thought it would be amusing to see you struggle against such a monster. I just thought you were being stupid not using my power, but seems you're even more of an idot than I thought! What person forgets about making a deal with a demon king and keeping him sealed away in their body!? If you keep that crap up, you'll get us both killed! Now focus on my power and let it flow through you as if it was your own spiritual energy, only then will you unlock true power. Now get out before I truly get angry"

(Heh that fool, he has no idea i planned this, by fogging a part of his mind, he forgot i was even here. But that's only because he's still new to this, the more used to my spiritual energy he becomes the less i can effect his mind...) Back to reality Kasuke let the demon king's energy flow through his boosting his spiritual energy.

Asura launched the small sphere towards the top of a nearby tree thereby signaling them to begin. With that, Mashida moved at great speed, moving with red electricity swarming around his body with the 4 triangles on his neck. He could feel a burning feeling in his body since he wasn't used to using the demonic power. Using all his power to leap from the ground towards the top of the large tree where the sphere floated at the tip of the tree, a sudden feeling of fatigue washed over him.

His dark blue aura vanished as he fell from the tree missing the sphere, hitting the ground out of breath. "Kasuke!" Naiomi cried out rushing over to her friend as he laid there a little pale trying to regain his breath. "Are you ok!?" She responded placing her hand on his forehead. Suddenly she found herself within the dark void where the demon king sat on his throne with a sadistic grin on his face.

"Ah, welcome Naiomi, I'm surprised to see visitors here so soon"

"Where am I!? Who are you!?"

"Heh, I'm the demon king Akunomi and you're within this i***t's subconscious. Not long ago, I made a deal with him: If he let me possess him, I'd give him the power to kill the demons of this world. Sadly, I can't seem to take control of him, only give him fractions of my power. For now, I'm nothing more than an energy multiplier for the welp"

"I-I'll have the great priest of the city of Kiodon exorcise you from his body so he can be free of your corruption!" She looked at him with a serious look clinching her fist.

"Hehe, hahaha! You amuse me girl, have you even been to an exorcism before? Something like that takes a huge toll on the body of a mortal...Let's say you took him to this "Great Preist" You should be aware the survival rate of an exorcism is merely 30%-10% depending on the strength and endurance of the vessel the demon possesses. So go on, exorcize your tear squad member, even if he did survive, he'd be farley weak for a while and never reach his goal of wiping out all demons of this world. Oh and before you go...I'd highly suggest not telling anyone about me to anyone, that would cause some problems for both you and him"

Naomi blinked, finding herself back to reality, her hand still on the shinobi's head as he finally regained enough breath to stand back up. Asura looked at him unsure of what just happened, but decided to let it go. "Come now, don't use some power at once into a mere movement, that will just waste your stamina, especially if you're new to using spiritual energy" Kakuke took a deep breath, using only small amounts of his own power to increase his speed like small temporary boosts instead of using it all at once and exhausting himself.

Naiomi was a little shaken from meeting Akunomi, but was worried about what could happen to Kasuke, they may've just met, but she could feel a growing friendship between them. She knew Zenra wasn't even going to try to be friends with them anyway. She followed a little far behind as Mashida jumped from tree to tree, moving swiftly through the forest, going deeper, away from the field that was by their unit.

That's when the red sphere of light changed from it's red aura to a dark purple. (Not doubt this is some kind of trap leading us somewhere where a demon is waiting. No matter, I won't let it get away) He continued to follow it when Asura felt the dark energy connected to his controlled attack. He quickly followed after them...

Kasuke once again found himself in the middle of the forest. (The forest again? Can't demons be more original where they're attacking!?) He thought. (The forest is a maze to some and rarely have many people around. Meaning if a mere human stumbled across a demon, they'd probably be killed or get lost before getting a chance to tell an exorcist about the location or type of demon. In some ways it's rather smart for a devil since many are dumb as rocks) Akunomi commented within the boy's mind.

Just then a figure rushed past him like a bullet. He didn't even have enough time to turn his head all the way when a pale man dressed in blood red clothing came out from the trees, attempting to grab Kasuke when Asura once again stood between his squad member and the attacking demon. Shigatomi had his arms crossed in a blocking position as the demonic man's fist struck the captain with immense force. Steam seem to be emanating from the assailant's fist from the velocity of the attack.

"Hehe, out of the way, I want the young one behind you, I sense great power from within him" The demonic man had pale skin, long red hair with purple eyes. A sadistic grin grew on his face when a red flame-like aura lit up around the captain's body. "Spiritual shockwave" Throwing his arms out in both directions he released a powerful shockwave sending the attacker staggering backwards before landing on his feet.

"Hehe, I guess you're not just going to hand him over. Very well, I have many ways to defeat you" Aiming his palm in Asura's direction he cried out: "Demonic art: Chains of despair!" Purple energy in the shape of chains rose up from the ground around the elite exorcist in all directions, wrapping around his arms and legs keeping him in place. "I have many demonic techniques I've mastered over the years that have proved useful in fights such as this. So then, you're the one called Asura Shigatomi correct? For such a high-ranking exorcist, you don't seem all that intimidating. Are you sure the Exosagins didn't make a mistake in making you an elite exorcist?"

"Don't underestimate me" The exorcist focused his power into the chains, the purple aura suddenly being changed to a red aura before Shigatomi broke out of them. The chains evaporating into mists of light. "Secret art: Strike of Atonement" The shinobi advanced his target as a golden light engulfed his fist. Asura landed a clean hit on the demon's face but quickly realized they were still standing. His foe had blood running down his face but still grinned ignoring the blood.

"I hope that wasn't your trump card, otherwise this little duel won't get any more interesting"

(H-how is this possible!? That move should've obliterated him, that technique is said to completely erase any essence of demonic spiritual energy!) "Both of you run! Get out of here now!" He demanded motioning them to escape. The two nodded rushing further away from the fight.

"Oh, leaving so soon? What's the fun in that? Secret art: Demonic barrier" Kasuke was moving through the forest when he struck something, landing on his back. He looked up to see a dome made of spiritual energy that looked like purple water.

"Damn it, that creep must've created this to keep us from running away" He sat by the barrier when Naiomi caught up with him. "What should we do? I doubt neither of us are strong enough to break through this shield" She asked.

"We'll just have to wait and see how this battle goes, wait here" Kasuke took a step forward when he felt his teammate grab his arm. "Don't go! If you go, you'll be killed!"

"We're trapped inside this barrier, even if I waited here, he'd find me anyway, just wait here, I don't want you getting hurt or worse because of that demon" Naiomi blushed with a surprised look on her face, no one had ever said that to her before. She watched as Mashida rushed back to the battle. She wanted to go, but what could she do? At her current level she knew she wouldn't be able to even scratch the demon...

CHAPTER 3 Rising Tensions

Meanwhile Aura made the symbol with his index finger as he had before I mid-air, "Cube of entrapment!" The symbol broke into wisps of red energy that floated around it's foe before trapping him within the red transparent cube. "This move worked before, it should work agai-" In a mere instant, a surging pain rushed through his body. He looked at the human-sized cube to see it fading away.

"B-but how, no one's ever been able to escape the cube of entrapment...what's g-going on!?" His eyes widened as he realized his enemy was standing right behind him with his back to him. "You don't deserve to call yourself an elite exosagin, I've fatally damaged a vital area in your abdomen, if you don't seek help soon, you'll most-likely die"

Kasuke watched from behind the trees nearby and could tell his captain wouldn't last much longer. (I need to save him! Help me!) Mashida found himself back within his consciousness. "Help me save Shigatomi!" The ninja said with a worried look on his face.

"Hehe, why would I do that? What use to us is he? You've only known him for two days. I'm sure you'll get over it" Just then the void began to shake as the white platform turned red. Kasuke looked up at the demon with a cold soulless look of anger in his eyes as he approached him.

"Sigh, what can you do? You're just a mere human, to the world I'm a god. Are you really challenging me?" Akunomi rose up from his chair as both stared each other dead in they. The demon grinned throwing his palm like a dagger right for Kasuke's eyes attempting to jab them out when the human caught his hand, bending it back as it let out a loud c***k that echoed through the void.

"Ack! Damn it! You bastard! How did you do that!?"

"You forget this is my mind...in this void...I'm as strong as I believe I am and knowing your power, I know I'm strong enough to kill that unique demon" Both stared each other down...

Just then Asura and the demon felt immense power behind them. Both turned to see Kasuke entering the battle. He had a calm look on his face as demon energy surged around him. "K-kasuke, get out of here!" The man said weakly as he fell to one knee griping the bloody hole in his chest.

"You're finally fighting me? Good, I'll enjoying feasting off your negative energy" The assailant commented. Mashida created a small flame of green flames, shooting it at his captain. The wounded man closed his eyes in fear awaiting the feeling of burning...But he didn't feel it, instead he could feel the pain beginning to grow numb, he looked at the hole in his torso closing as if the flames themselves were healing his injuries.

"Get out of range Captain, my fight is with him"

"Are you insane!? He almost killed me and you're merely a C-rank exorcist!"

"If you want to continue the fight, be my guest, but your power won't be enough to stop whatever this monster is, he's the highest-level threat of demon I've seen. But I should have just enough power to beat him. My name is Kasuke Mashima, what's your name demon?"

"My name is Kedosaka, pleased to make your acquaintance, I can sense you have massive power within you, but it doesn't feel like only yours, do you have a high-level demon sealed within your body?"

"That's none of your business, what about you? How could a mere demon gain such power and intelligence as if a human?"

"From absorbing the power of demon hearts, with so much power, I was able to absorb the knowledge and power of multiple demon hearts until my power surpassed any other mere demon. Now that we got that out of the way, let us continue the blood-shed. Forbidden art: Time fraction!" Both exorcists watched as the sky and the entire forest around them was covered in a blood-red mist which made the moon appear red.

"Hehe, with time at a standstill, I can kill these two with ease" He leapt into the air, descending right for Asura as claws made of purple energy manifested at the tips of his fingers as he attempted to slice the man frozen in time to pieces. Just then he watched as the target broke into pieces of blue wisps of light just before he could make contact. "Impossible!"

Kedosaka spun around to see Kasuke standing there with a barrier around his body protecting himself from the forbidden technique. "Impressive ability, stopping time in a red mist of demonic energy. But I can easily counter it with a protective barrier around myself rendering it basically useless"

"This isn't possible, no one's ever been able to move through time fraction!"

"Well then apparently you have never faced the power of a demon lord" (I can do this, I feel like myself, but at the same time...him)

"RRRgghh!!! Demon heart!" The sadistic man used one of his demonic claws to slit across his chest causing blood to gush onto the grass as the mist around them vanished from the area. Asura found himself standing a few feet away from the battle as Kasuke slowly approached the sadistic man just as a large bloody heart grew from the ground like a plant.

"A-a demon heart!? But...how could someone just summon one single-handily!? Their leader stood there both in shook and in fear. "Just how powerful is that guy!?" He turned to see his unit member continue walking with no hesitation. (What happened, a moment ago he didn't even know how to use spiritual energy correctly, now he's surpassed me in power and technique!?)

"What is a mere demon heart supposed to do? I know all there is about that anomaly, a massive buildup of death and negative emotion such as guilt, anger and sadistic thoughts. Which means I know how to destroy it as well"

"N-never! Face the power of my 5th demon heart absorption!" The man stabbed his palm like a dagger into the massive heart as blood gushed out of it, covering his hand. The captain watched as the heart began pumping faster, it's veins becoming more visible as Kedosaka's aura changed to a silver aura as it burst out of him like an uncontrollable fire. "Now then...let us start the final round...my power is far greater than it's ever been! Bawhahaha!!

His red hair rose up behind him from the force of his power as his eyes were completely covered in black. Kasuke with Akunomi mostly in control, stood unphased by the immense power up. The assailant took a step forward, the sheer force of just walking caused the ground to c***k as if it were ice.

"Heh, you should stop this before you die"

"What are you talking about!? With the power of five demon hearts I'm invincible!"

"Go ahead and attack and you'll see what I'm talking about" The demonic demon advanced right for him, destroying the ground behind him as he went for a full force strike to the shinobi's face. Kasuke stood his ground has black electricity engulfed Keosaka's fist as he went for the final blow.

Before the moment of impact, Kasuke deflected the attack by smacking the foe's hand to the side. The force of the attack went past him, sending a powerful force of wind at Asura, sending him and everything in that direction flying back like a hurricane. It felt like everything stopped for a second when the demon man felt a crippling pain in his body before hitting the ground barley able to move.

"D-damn it! W-what did you do to me!?"

"I didn't do anything, it's just your weak mortal body can't handle that much demonic power flowing through your body. If I had to guess, you damaged your spiritual flow in your body and are unable to move your body correctly. As for the demon heart, I shall be taking it" Kedosaka forced his head in the exorcist's direction as he walked over to the colossal beating heart.

"Observe" He stabbed his hand into the heart, absorbing it's power. As before the heart's heartbeat sped up, growing faster and faster when it suddenly let out one last heart beat before dying. The blood-red heart bean to grow black and corroded as it wrinkled away. "I told you I could easily dispose of your demon heart. In fact..."

Asura watched in shock as his ally stabbed into the defeated man's chest, siphoning his power as well until the human vessel was pale and skinny with barley and meat on his body. "Mmm, you really did have a lot of power and now it belongs to me" Kedosaka tried to choke out words but died as he laid there looking like an old shriveled up version of himself. "Seems or work here is done" Akunomi went back within the man's consciousness as the god-like power faded from his body and he collapsed.

"Kasuke!" Asura rushed over to him. Trying to shake him awake with no luck. That's when Naiomi came dashing over. "Kasuke!? What happened captain!?"

"I...I don't know...he somehow fought off that devil. But once the battle was over, he collapsed" Tears filled her eyes as she looked at her friend's unconscious body. "Kasuke...KASUKE!!"

Deep Within His Subconsciousness...

"Am I dead?" The exorcist asked himself when he heard Akunomi: "You're not dead fool, you're in a spiritual trauma coma. Your body couldn't handle my power flowing through you for the first time so it gave out. Feel lucky...if it had been anyone else, their heart would've given out or worse. Your body on the other hand seems to be in stable condition. Think of this coma as your body's way of recuperating from the fight"
