Y/n had just finished watching the rating game between Rias and Riser. Rias knew how to plan accordingly and he was proud. But that all shifted once Riser's queen healed her body with Phoenix Tears. She was able to take Koneko and Kiba out in seconds.  Akeno was the only one to truly set her back but even she was overwhelmed.  Y/n proud of Issie for getting the second liberation on his sacred gear. Honestly, he hasn't even achieved it since the sacred beast control his negative emotions and only anger can bring his next stage out.  But Riser truly made the Dragon Emperor upset by saying that if Issie dies in the game it's considered an accident. Something that he's sure Riser has done before. Just then a magic circle appeared in the boys room as he entered seeing Greyfia standing in the middle of his room.

"I assume you're here on sirzechs orders?" He questioned as she shook her head with a smile.

"You are too sharp. But yes I am. He thinks that you and the welsh dragon emperor should crash the wedding." She said but Y/n looked down at his arm. 

"I want to burn him. I want him to feel the pain he inflicted on my friends and student." he said as his dragon roared. 

"Then I suggest you get moving sun dragon. Rias' servant is currently on his way to the party." She smiled as a golden flash came from the boy showing him in his now ancient Egyptian armor. 

"Then by all means." He said showing her his outstretched hand. "will you accompany me to the wedding? Ra is doing his morning duties and I'm sure he won't be able to take me."

"Of course." 

the two began to shine before vanishing in thin air. Y/n appeared next to Issie as he had just put down a guard shocking the fighter. Y/n suddenly vanished and had a guard by the throat as he tried to sneak attack his schoolmate. reeling his head back Y/n dealt a powerful headbutt as Issie heard a sickening crack.

"Damn senpai. But wait why are you here and what's with the get up? Did you come back from a costume party?" he questioned but Y/n just chuckled.

"Come we must go see Rias and crash a party." He smiled before Issie nodded fired up as the two stood in front of the door to the party. "Should we knock?" He asked the younger male as they both looked towards a guard that appeared behind them. 

The both of them smirked as they grabbed the guard and pulled him in. Throwing the guard forwards Issie and Y/n ran and punched the male in the face sending him through the door. Breathing in and out Issie had his arm outstretched shocking the pure demons. Y/n walked besides them and smiled. 

"Rias!" He smiled causing Issie to be confused at his now cheery demeanor.

"Uh,- Senpai?" he asked as the upper schoolmate ignored him.

"Why didn't you tell me it was tonight? Here i am wearing nearly nothing at all." He laughed as he looked towards Riser. "Oh and the groom is here. I hope we didn't barge in unexpectedly. Did we? your majesty?" He smirked seeing Risers mood sour seeing the two. 

"Who do you two think you are?" he growled as Issie stood next to his teacher. 

"I'm issie hyuodou and I'm here to take Rias back home. Her virginity belongs to me!" He yelled causing Y/n to stop with his friendly demeanor and turn to him with a sweat drop.

"Allll righty then." 

"Y-Your bastard!" Riser growled as his sister looked at with with an embarrassed face from what Issei said. 

"What is this guy saying?"

"Apprehend them!" Riser ordered as more guards surround the two. But they were all suddenly on the ground in pain. No movement. no nothing. 

just as more showed up Kiba slashed three with a sword made out of ice with Koneko kicked three more and Akeno shocking five with a blast of lightning. 

"I was wondering when you two would show." She smiled as Y/n chuckled.

"Please like I would miss this." Y/n smirked as he walked towards Riser. 

"Wait senpai." 

"What is the meaning of this." a high class devil asked as another one questioned if it was Risers idea.

"It's just a little entertainment I prepared." A voice called out as the devil king lucifer appeared as Y/n greeted him like old friends.

"Big brother you know Y/n?' Rias asked as Y/n stood in the middle of the room.

"Not entirely. This is our first in-person meeting. I've heard a lot about him from his teacher." Sirzechs smiled as Y/n stood next to Issei as the younger male took a position next to him. "I was quite underwhelmed by your performance in the rating game Riser. My sister nearly beat you with herself being understaffed. Plus I'm sure you were hoping to fight the mortal. But never got the chance. Am I correct? Besides we don't have a celebration like this everyday. I thought it could use some flare." 

This caused the pure demons to be shocked as Y/n stood there with a smirk. 

"Honestly I was hoping to join but I just got caught up in some things. But you're helping me out with this." Y/n said as he stood straight. 

"Hold on senpai I want a battle against Riser too. I want t o bring Rias back." 

"You there boy. You use the power of the dragon while your friend there has a healing ability from what Rias has told me. Possibly one that can rival that of the phoenix family. I for one would like to see what you two can do. Which is why I had Grayfia bring you both here." 

"I get it now. You want a fight."

"Dragon vs. Phoenix. But it seems Y/n wishes to test his strength against you."

"More like put him in his place."  Ra spoke in his wielders head.

"I believe your guests would enjoy the spectacle."

"What a marvelous idea my lord. I'd be more than happy to obliged your request." Riser spoke as Sir zechs looked at the two. 

"As for you dragon there are many here have quite an interest in seeing your abilities. Would you be kind enough to show them what you're capable of?" 

"Yes." Issei answered confidently.

"Issie." Rias spoke before Riser put his hand in front of her.

"Easy my dear. Riser is sure he can handle himself."

"Uhm hello. I'm here too." Y/n spoke 

"I don't answer trash." Riser spoke but Y/n pointed out he just did making the pure blood annoyed.

"If you don't mind Issie let me fight fire-crotch first." Y/n said making everyone look at him with confusion.

"Senpai?" 

"Look I know you have a vendetta against him. But remember I wanted to fight him first. But how about a wager Riser?" Y/n spoke making the pure demon confused.

"And what would that be mortal?" he questioned as Y/n held out three fingers.

"Three powerful blows. They're all I need to take you down. If i win. I get that many pieces from your peerage." He said causing everyone to grow angry.

"Are you insane mortal?! you can't do that!" A male on looker said

"Talk about speaking out of turn." a female pure blood spoke 

"Enough. Let's say I agree to this wager. What do I get out of this?" Riser questioned as Y/n smirked.

"You can say that you, Riser Phoenix, are the strongest devil in the under world. Bar none." Walking up the the male Y/n held out his hand. "Your title would make you legendary. Plus you get to kill me in the process." 

Looking down at the male Riser noticed the tattoo on the male and smirked. Griping his hand he set his hand on fire as the two gripped tightly. 

"Deal. What pieces do you wish to choose?"

"Big brother!" Ravel spoke only for him to quiet her.

"Let the big boys talk. Now who?" 

"The first punch will be for your rook. Isabella. The second blow for your knight Carlamain. The final and most powerful one will be for your Queen Yubelluna." He spoke making the Pheonix peerage look at their king with shock. 

"Then it's settled. Y/n, Riser please make your way to the arena." Sirzechs spoke as the two began to glow.

"Issie." Y/n spoke as he looked over his shoulder. "Watch and learn."  Quickly the two vanished as they both appeared in a open arena with chess piece statues.

Y/n stood in between the knight and pawn piece statues as Riser stood in front of the king. Y/n began to do some side lunges as Riser watched in annoyance. But the phoenix lord was glad to finally put this annoying bastard in his place. 

"You messed with the wrong family mortal. My brother is gonna lay you to rest." Ravel spoke as Y/n just smirked before stretching backwards.

"Let's see about that." 

"I'll end this in one move." Riser said as he charged up a powerful flame attack before throwing it at the boy as Y/n smirked and began to mumble to himself. The attack flew faster and faster at Y/n before connecting. 

Everyone saw Y/n's silhouette vanish in the blast as a massive flame like explosion went off. 

"Senpai!" Issie yelled as every demon saw the boy vanish in the attack.

Smoke leaked around the area like fog. Riser smirked seeing ashes on the floor where Y/n stood. Smirking he turned around and began to leave but stopped as a overwhelming presence made itself known. Snapping back to the area Riser saw Y/n standing there, no scraps, scratches or burns. Cracking his neck Y/n leaned forwards in a runner position with a golden outline slowly appearing.

"You call that a finishing move? Three." 

"Wha-" Riser couldn't finish his sentence as a sonic boom went off with Y/n appearing inches in front of Riser with his fist lightly touching him. But the phoenix lord felt his head come clean off. Risers body collapse onto the ground shocking everyone.

"Alright Senpai!" Issie yelled out as Risers body slowly stood up with his head reforming from flames. 

"That's my son!" a voice cheered as Rias turned around seeing a adult male standing next to the food as he was drinking some wine and had a bit of fruits and vegetables. 

"Who is that? Did he just call Y/n his son?" 

Riser finally formed back as Y/n stood behind him with his arms crossed. Annoyed with the pure blood.

"That's how LONG you form. Dear god at this point I've already won." He said as Riser growled at his opponent. "By the way. That's your rook gone. Shall I get started with Carlamain?" 

"Don't you mock me boy!" He yelled before surrounding his body in flames. "I am Riser the next heir of the phoenix throne. You are nothing!" 

"Well this nothing right now is getting bored. Tell you what I won't move from this spot. Do what you want to me." Y/n said as Riser grew much more angry and annoyed.

Riser growled before bringing a powerful jab to the boys left cheeks as his cheek began to burn due to the hellfire surrounding him. Smirking Riser could see his handy work but his eyes widen as the injury vanished in a form of golden dust.  Backing up Riser shook in anger as he saw his attack do nothing. 

"What? How?" he questioned as Y/n smirked.

"Surely you saw the mark on my chest right? The mark shows a griffin. The symbol of one of my gods dragons. Back in my time in ancient Egypt. My god, RA, chose me to be his champion. I have fought thieves, fallen, demons, and even a trio of gods." He said before moving towards Riser. "Would you like to meet my partner in crime?" He asked as flames appeared out of no where as he slowly closed his eyes. 

"All mighty protector of the sun and sky. I beg of the, please heed my cry." Y/n began as the flames grew and grew spreading all around the arena before moving to the air and forming a circle. "Transform thyself from orb of light and bring me victory in this fight." Everyone in the room watched as the sphere began to shine and solidify as RA smiled seeing his dragon once more while the demons watched in fear. "I beseech the. Grace our humble game. But first I shall. Call out thy name!" Y/n spoke before snapping his eyes open. 'Winged dragon of Ra!" he yelled as the sphere began to crack and shift as a mechanical like divine dragon made out of pure gold and sunlight made itself known. The dragon looked down at Riser before looking down at his partner.

"Ddraig? What is that?" Issei asked as Ddraig looked at it from issie's eyes. 

"That...that's one of the godly dragons. far stronger than myself." He said making Issie hear the hint of fear.

"So Riser. you ready? Cause now the real fight begins now. Let's see just how long you can handle our power." Just then the winged dragon turned into flames, flew up and slammed into Y/n as the flames consumed him. 

" Sun dragon Balance Breaker!" Ra yelled out as Y/n was incased in golden armor with blue gems. A piece of armor he mastered over thirty years. 

Riser grew angry at the sudden reveal of the sun dragon emperor.

"Don't act like you've won just because of your title!" he spoke making Y/n laugh.

"Funny cause if I remember last time. You used your title as the immortal to get your way. Now it's time for someone to put you in your place." Y/n spoke before taking off in sonic speeds as Riser felt his stomach cave in as Y/ns fist was planted firmly in it. 

A sonic boom went off as wind jet off of risers person with him being sent away from the dragon emperor. Riser didn't have time to recover as Y/n flew in and grabbed the back of his head and slammed it into the ground. Both of his wounds trying desperately to heal. Just as Riser was about to fully recover Y/n shot multiple wing projectiles into the demon. not only staggering him but burning him as well. 

"Two." Y/n muttered before doing a flurry of attacks and finishing it off with a massive uppercut. Blood and teeth flew out of Risers mouth as Y/n caved in the devils right cheek. Riser skipped across the arena and into the wall. 

"H-Holy shit senpai." Issei spoke as Rias and the rest looked in shock. Meanwhile a flash of light went off as Ra smiled. 

"I'm sending this to Geb. hashtag fried chicken."  he said spelling the entire thing out. 

Riser flew out of the rubble and summoned a massive ball of fire as he glared at the boy feeling his rage overcome him. 

"JUST DIE YOU PIECE OF SHIT!" he said before throwing the ball of fire the same size of a small star. Y/n stood in front of the blast as RA chuckle. 

" This is gonna be good." he said as Y/n stood in place as the attack broke the ground and connected with Y/n as the blast sank into the ground.

Riser landed on the ground with a smirk at his handy work. But winds picked up as the attack was slowly moving up like a sun coming over the horizon. 

"What?" Riser exclaimed as he saw Y/n carrying his attack with just one hand. 

Another picture went off as Y/n heard Ras voice come from one of the projections. "I'm so proud of you son! You're growing up so fast!" 

Y/n felt himself get embarrassed a bit before  his gear shined and began to absorb the attack.

" Divine,Divine! " 

"Only two? That's pretty weak. oh well." Y/n placed his feet deep into the ground as his fist glowed brighter. Taking off the dragon emperor slammed his fist into the stomach of the male before flip kicking him into the air as a jet stream went off underneath the devil. A golden light vanished and appeared above Riser. The devil corrected himself before looking above him as Y/n flew down with his fist outstretched.

"One." Y/n sternly said as his body turned into flames before he connected with Riser's nose. The two flew down as flames surrounded them both before expanding and growing wilder. Mere seconds before hitting the ground Y/n yelled out one of his most powerful attacks. "GODS PHEONIX!" Ra's silhouette formed around the two before an explosion went off. 

Everyone felt the shockwave from the attack as glass shattered and tables fell along with some devils. The statues and walls crumbled and fell as they had taken the blunt of the attack. Smoke showed up on the screen as everyone waited for that obvious victor to rise. But some had hoped that Riser was still in the fight. Flying out of the smoke the flamed body of the sun dragon emperor appeared in the sky before the armor except for the wings vanished. Y/n flapped his wings in one motion sending the smoke away as Riser laid in a massive crater. His body ruin to all hell and his healing just not working as his flames were over powered by Y/ns. 

Landing in the crater Y/n grabbed his opponent by the hair and tossed him out before moving away from him. A smirk of victory appeared on his face as he turned to the projection of everyone and bowed. The only one cheering was RA as he danced and wrapped his arm around Sirzechs. Whom himself was in shock as well. 

"That's my son for you! A powerhouse!" 

Y/n and Riser appeared in the room as Ravel flew to him seeing her brother unconscious. Y/n moved through everyone and smirked. 

"So just like our deal said. I will be taking his rook, knight and queen. Maybe he'll learn something after this. Issei. that's how strong you can become one day." He smiled at his student/schoolmate as Issie looked at him with respect and a hint of fear. 

"Y-Yeah." 

Just then the three girls came up to Y/n as they kneeled to him. 

"Our god." They commented but he stopped them.

"No. I'm no god. I'm a simply a mortal." He smiled as he held his hand out three marks of Ra (the trading card art) appeared on their person. Isabella on her arm, Carlamines was on her thigh and Yubelluna was on her right pectoral muscle. "Welcome to my group girls. May no one stand in our way." He smirked before RA ran and hugged his son. complementing him on his fight and how much Y/n reminded himself when he was younger. Strong and ruthless but soft and caring.

Rias looked at him with shock at finding out about his power. But now it's safe to say that Issei won't need to fight Riser as Sirzechs simply called off the wedding due to Risers condition. Perhaps after riser beats Issie but that won't be for a long while.
