Rias froze as she stared at Asta unable to believe what he had just said, how could the boy be so foolish as to challenge a devil to a fight. Yet at the same time Rias couldn't help but to feel a great swell of happiness at the fact that he was willing to fight for her. Her eyes were locked on his back as the boy walked towards the hallway that would lead to the summoning circle which would take him to the arena, she wanted to wish him luck or beg him not to fight the older male, but her voice caught in her throat as he turned back to look at her a large smile on his face as if to tell her not to worry that he'd win this fight.
"Rias!" A voice echoed from behind them causing all eyes to spin to look at the door were Issei was standing his arm now covered by a red gauntlet, Yuno following shortly behind him, before the brown haired boy raced over to Rias's side his eyes quickly locking onto her older brother. "I wanna challenge Riser to a fight for Rias's freedom." he proclaimed quickly, her older brother giving him a brief look before looking towards the large monitors that were showing the arena.
"Someone else has already challenged Lord Phenex" He stated calmly causing Issei's eyes to follow the older man, quickly finding the image of Asta standing calmly, a massive dirty black blade held in his right hand.
"Let me replace Asta, it's only fair that the one to fight Riser is another devil" Issei said quickly trying to come up with some way for him to fight Riser, not because he wanted to prevent the other boy from getting hurt, but if he fought and beat Riser saving Rias from her forced marriage then she'd realize that he was a better choice then the other male and would become a member of his harem.
"No, Asta challenged Riser and he accepted so I will not allow a substitution, it would be taken as a show of favoritism." the current Lucifer stated calmly, causing the younger boys face to drop his mind obviously trying to figure out some way to convince the new king to let him fight. But nothing Issei could say would make the older devil change his mind, he wanted to see just what made this ash haired boy so special to Rias, and what better way to find out.
Asta inhaled deeply before exhaling, steadying his nerves and focusing his thoughts, as he prepared for his fight with the older man, the Demon-Slayer sword held firmly in his right hand as he looked at Riser. His eyes narrowed as he saw the arrogant smirk on the older mans face, his arms crossed across his chest and his stance loose as if he didn't have a care in the world. The fact that the older male was already writing him off as if he had no chance really pissed the magic knight off, and Asta fully intended to wipe that arrogant grin off his face.
"What would you desire if you win Asta" SirZechs voice echoed from beside them causing Asta's head to whip to the side only for his eyes to widen at the massive image of the red haired mans face, slowly calming down as he realized that the man was probably using a similar spell to what Mimosa had used to reveal the interior of the dungeon. He couldn't help but to raise an eyebrow as his mind processed exactly what the older male had said.
"What?" he asked calmly, causing the older man to slowly shake his head before looking back at him.
"I will grant you one desire if you defeat Riser, so what will your desire be." He explained slowly, doing his best to make sure that the younger boy understood exactly what he was getting at. Asta's eyes widened in understanding before narrowing again as he smiled at the man.
"All I want is Rias's freedom" Asta proclaimed calmly as he turned to glare at Riser, the arrogant devil still smirking at the boy.
"Say what you want human, but when Riser wins, Riser will take Rias as Riser's bride, and she will bear many children for Riser." The arrogant Phenex stated with a chuckle at the end, causing Asta's eyes to narrow further, anger beginning to shine in his emerald orbs.
"So be it, with the prizes stated this fight may now begin." SirZechs said calmly, as if he was unbothered by Riser's last sentence but for those who truly knew him they knew he was angered by Riser's statement.
Asta shifted his stance as he prepared to charge, pausing as he saw Riser's hand raise into the air.
"To show you how outclassed you are, Riser will allow you to have a free attack." Riser stated calmly as he held his arms open, showing just how little he believed Asta could hurt him. The ash haired boys anger spiked at Riser's sentence, before he slammed his foot into the ground and took off, the pavement at his starting point flying into the sky as he charged.
SirZechs barely held in his sigh at the arrogant devils speech, he was well aware of the fact that Asta wasn't going to be able to do much to the man, after all Risers regenerative powers were amazing, even he could admit that, but that didn't mean that Riser should treat the boy that his little Rias cared so much about in such a cruel manner. His thoughts were interrupted though by the sound of a pair of soft chuckles.
"First mistake." The dark haired youth, named Yuno if he remembered correctly, stated calmly, with a soft chuckle, while the red haired boy next to him, Leo he believed, laughed outright. Before Yuno turned to look at him, a small smile on his face. "Only a fool underestimates Asta." Yuno stated calmly causing SirZechs to raise an eyebrow before turning to look back at the charging boy.
Asta growled as he swung his sword, the blade whistling as it cut through the air, before the tip cleaved a crooked gash across Risers chest, the arrogant man crying out in pain as Asta continued past him, his feet digging into the ground to slow himself down before spinning and charging at Riser a second time, his sword once more slicing not just the air but also creating a deep cut into the mans side, sliding past again as he spun to look at the older man.
Riser growled as he clenched his new wounds waiting for his magic to begin healing the wounds, but as seconds passed and turned into a minute without the cuts healing at all, he growled as he tried to sense his magic to figure out why, only to gasp in shock as he realized that his magic was being prevented from reaching the wounds. He snarled as he dodged out of the way of Asta's next strike, before looking at the younger boy, knowing that somehow the boy was responsible for the way his magic was currently acting.
Asta growled as he slammed his foot into the ground, shifting to try and launch back at Riser, only for his eyes to widen as he saw Riser right in front of him, the older mans blood covered hand slamming into Asta's stomach, the power behind the punch as well as the fact that Asta was off balance enough to send Asta bouncing across the floor. The boy quickly flipping back to his feet before flipping the sword so the flat of the blade blocked Riser's incoming kick. Asta snarled as he tried to move at the older man again, only to quick raise his blade to block again, Risers speed being enough to give him the advantage, but Asta refused to give up.
Riser growled savagely as he launched at Asta yet again, using his speed and battle knowledge to his advantage. The fact was that Riser had no desire to toy with the human any longer, after all the boy had hurt him, and was making him experience pain something that no human should be able to do. Riser was fully intent on paying the boy back a thousand fold not just for the pain he was currently feeling but also for the fact that he a normal human boy was able to cause Riser injury, that was an offense that couldn't go unpunished. With a dark grin he lifted an inch off the ground before flying at Asta, his hand shooting forward to grasp the boy by the face before he flew him into one of the four massive pillars, causing Asta to cry out in pain, before Riser flew backward, only to shoot forwards again his foot slamming into Asta's stomach causing the boy to cry out in agony as blood and spittle flew forth from his mouth.
Riser grinned as he flew back and skyward, watching as Asta stumbled away from the pillar, before Riser once more shot forward, this time angling so that he would be coming from behind Asta, his foot slamming into the ash haired boy's back sending him crashing forward while Riser flew high, holding his hand out, palm spread aiming at Asta's currently struggling form. His savage smile grew almost psychotic as a fire ball was generated in his palm, before he fired it at Asta, expecting the blast to incinerate the boy, but to the older mans shock Asta quickly shifted his blade slamming the flat of the blade against the incoming fireball sending it rocketing back at Riser, causing the older males eyes to widen in surprise before he simply flew to the side to dodge the reflected attack. He couldn't prevent the gasp from escaping his lips though as his eyes landed on Asta who had taken advantage of Risers distraction to launch himself towards the older man, the tip of the boys blade creating a second slash across the older devils chest, intersecting with his first one to create an x.
Riser couldn't help but to scream in a mixture of pain and anger as the boy managed to create yet another wound on him, his anger boiling over, the older male let loose a furious roar before flying after Asta.
"You wish to fly human, allow Riser to help you" He snarled angrily as his arms grabbed Asta under the armpits, as he pulled the boy so his back was against Risers chest before Riser shot them higher into the air, once he was sure they were high enough up, he spun and flew towards the floor. Asta's eyes widened as he realized exactly what Riser was planning before he began struggling to get free, shifting and pulling, before finally slamming his head back, causing the older man to recoil in shock and surprise as he loosened his grip just enough for Asta to slip free. But Asta knew that it wouldn't matter at all if he couldn't find some way to slow himself down, his mind working a mile a minute the ash haired boy couldn't help but to frown as he figured out what his only chance was, and so he waited until the time was right when he slammed his blade into one of the four pillars, gnashing his teeth as he felt his arm pulled painfully, more then grateful for all the training he had done knowing that he would of ended up letting go of the handle without it.
Asta couldn't help but to groan as his feet finally touched the floor, hoping for just a moment to let his arm rest, his hopes came to not though as he heard clapping echoing from above him, turning his green eyes up to look up at Riser who was clapping slowly as he looked down at Asta a psychotic smile on his face before he held his hand out again, this time charging a much larger fire ball.
"Riser has grown tired of this farce, so now Riser will end this." Riser stated as he held his hand over his head the fireball still growing as Asta simply stared at him for a moment, before his eyes narrowed as he looked down at his blade, grasping it with both hands, one on the handle and the other lightly holding the blade itself as he closed his eyes focusing.
"Say goodbye human!" Riser declared psychotically before flinging his hand forward, the massive fireball flying directly at Asta, before Riser fired a second smaller ball directly into the large one. Laughing like a mad man as the large orb grew for a moment before exploding the flames covering the area that Asta once sat.
Rias froze as she looked at the large magical screen, unable to believe what she had just seen, it just couldn't be possible, Asta couldn't be gone, but as each second passed with Asta now coming out of that inferno, her mind couldn't help but to begin wondering if she had just watched her crush die.
And I think I'll end this chapter here, I know it doesn't have as much dialogue as my chapters usually do but I hope that everyone still likes it, also please remember this was my first time writing a true fight scene. So please remember to leave a review and thanks for reading.
