Demon King sat upon his throne sword sitting next to it. It was a black odachi with a screaming demon pommel. He clenched the handle worried he lose it. The doors to the room came open. It was his son in light black armor holding a demon helmet. "Father the Shadow Cohort has fallen. I am sorry" he stared plainly. Demon King sat back in his throne deep in contemplation. "He'll come here now. Nothing, but the army with what little weapons we posses can fight him now. This Slayer is good! Very good!" He said excitedly. "Sire?" The teen asked confused. "You don't see the preparation this individual took do you?" He said standing. He grabbed the scabbard of his sword as he walked towards his son. "Just as well your intelligence is small" he said walking passed his son. "What am I not seeing father?" He was annoyed and angry now. "This Slayer took the time to weaken us completely. With stealth and patience. He used our confidence against us. In one swoop he managed to turn the tide. But he under estimates me of course" the Demon King seemed happy by this planning. "But what should we do then?" The teen asked. "What else can we do but face it head on. We have no machines to wipe this individual out, no fire arms to take up the upper hand? We are truly to fight this person with nothing but the weapons we possess. He evened the playing field" he kept walking towards the main gate. "We should flee then father?" The teen begged. Demon King slapped him, "Run like a fucking coward when a warrior of this caliber has come to challenge? BE A FUCKING LAUGHING STOCK AMONG THE REALMS! Find some courage, or go cower with your mother! Useless heir!" He said leaving his son. The boy rubbed his face and followed after his father head down. He put on his helmet, 'this what my brother endured? He is a heartless man. Yet I still seek his approval in his eyes. Why?' The boy was deep in thought as they stopped in front of the gate. All soldiers formed shield walls. Archers stood behind at the ready. Demons mounted on six legged horses with horns and red eyes all armored.
A large black wall hung over the gate as it crashed into it. Darkness seem to seep in coming through small crevasses of the gate. It drip down from hinges, bolts, and spaces where metal on metal. It flowed into a pool and the gate began rattle and with one big explosion of fire shot back into the army that was to slow to move. Many soldiers were crushed from the impact. A blue passed through the gate moving about killing all. The figure was hidden inside the dust cloud.
Zeena ran to her husband and son. "See you found your courage to join us Zeena" the king said with glee and with a sarcastic tone. "We must flee now!" She said to her son grabbing at him. "No! I'm staying to face this!" He yelled back. She backed up at his gesture as he swiped his hand away from her grasp.
Soldiers screams broke the tension between them as glowing red eyes could be seen in the dust cloud was a silhouette of a warrior with two red katana's in his hand. Demon King mad a noice as he stopped breathing as he the figure became more defined. He could see the red oni mask, the gray cloak over his black body suit. But what he focused on was the weapons he held in his hands. "It can't be? Is that really you my son?" He walked over in a trance for a better look. Slayer stood staring at the king with cold eyes. The teen unsheathed a sword from his belt. Zeena was lost for words as she stared at Slayer with wide eyes. "It can't be…" she mumbled collapsing to her knees that were shaking. Demon King sprung forward landing in front of Slayer. "You truly are the rightful heir! All you have done proves it! You have made my proud son!" he said with happiness.
Slayer said nothing as he shot at him. His blade's edge formed a ripple of shadow that turned into spikes. He swiped his sword through the air sending shadow spikes that grew in size as they came at the King. He dodged as he's spikes struck stone splitting it and cracking it. His sword moved like a flash cutting though one spike for it to explode in smaller spikes. Some struck his armor and implanted themselves into his flesh underneath.
Slayer was already on top of him taking the offense. Demon King and Slayer moved like lightning as the clashes creating sparks. Their blades flashed and slashed as the moved about fighting one another. The young master tripped as he ran to help his father. "DONT INTERFERE LEAVE WITH ME!" Zeena shouted. He paid her no mind as rhe jumped into the fray stopping Slayer from a finishing blow.
Slayer's demeanor softened as he parried each attack away with barely any skill. "Stay out of this" he warned the boy. "No I will defend my father from you Red Demon! I have dedicated my life to protecting my king!" He pointed his sword at Slayer who waited for an attack. A blade came out of the boys chest as he was stabbed from behind. He spit black blood as the blade was ripped from his body. He fell to knees. He looked back at the king who was holding that blade. "Who asked you to come to my rescue?!" He said with annoyance. Zeena screamed in pain as she witnessed this. Demon King stared at Slayer shrugging, "What? He's just a whore's son" he swiped at Slayer. Zeena rushed to her son, "No no! Please no!" She screamed holding him. She pressed on his chest trying to stop the bleeding. He gave a few raspy breathes before dying. She began to sob as she stared daggers at the two engaged in battle.
Demon King brought to life shadow warriors that began to attack Slayer. He created shadow minions with sword hands that attacked the others. Deflecting that sttack Slayer pressed on Demon King, "Don't think I don't know your tricks!" Slayer accused. Demon King then slashed a line of black at his opponent cutting down a pillar behind him as he dodged.
Slayer flipped behind him slashing his back and right leg. Demon King groaned in pain swiping his odachi from behind missing Slayer. The katana's in his hands turned to red particles. He was now weaponless as he closed the gap throwing a punch into the king's gut. He grabbed his arm before he could slash his sword at him. He drove a fist into his elbow that gave a pop at the armor. He did it over and over till his arm bent at an unnatural angle popping. He dropped his sword and caught it with his good arm.
Slayer backed off jumping back creating distance. He manifested his soul weapon that turned black and the edge then flowed hot. Demon King stared at the bald, "Crafted your own soul weapon I see?" He said. Slayer said nothing as he sprinted forward. The two were a clash of blades. As each clash cracked the ground, slices in the stone, and destruction spread from them. Their very auras made the pressure around them unbearable.
Zeena ran with her son in her arms away from the carnage. She was met by Trax who was watching the fight with intrigue. "Trax please help me! You can save him" she pleaded. A large boom erupted from the battle as the two kept fighting all over. Bouncing off walls and spells erupted everywhere. Walls began to crumble.
Trax took his gaze away and looked at Zeena, "Karma comes in many forms Zeena. I'm sorry. You know the weapon he wields once met with flesh corrodes. Your son is beyond saving" he told hearing this she seemed to go deaf and in shock. Her mind cracked from this. She slumped down defeated as Trax watched the fight. Slayer flipped off the wall and drove a fist into the Demon King's face. He staggered back holding up his sword for a block he kicked Slayer across the yard. He slammed into a pillar cracking it. He shrugged off the blow and used the pillar a spring board. It crumbled and fell apart from force he put into his legs. He ducked a slash and came up slashing through the king's chest plate.
Black blood poured from the mouth of the mask. He was now crippled further from this. He had a broken arm, cuts on his back, legs, and now his chest. He heaved shallow breathes as he staggered to keep standing.
He then started to laugh as shadows crawled up the walls then hands came out trying to grab Slayer. He flipped and slashed through each shadow hand. Then he jumped into the darkness and was gone. The Demon King looked surprised.
"Your shadow control has gotten better hasnt it?" He said out loud. Fire balls then came from darkness from different directions. He slashed each as the erupted into explosions. He was struck once in the back sending him flying forward only to have another hit him from the front. He was now defenseless on his back. As three fire balls came at him all at once. He was shrouded in a sphere of fire that exploded making the pillars fall and the walls crumble. Slayer stepped from the shadows and walked up calmly to his father that was smoking.
He kept laughing as he sat up slowly all fight out of him now. "You truly are my prodigal son" he said laughing.
