Ajuka pov

"You did what!" Beelzebub listened with a smirk, as yuzu scolded dragons generations older than her.

"Tannin I left him with you to train his sacred gear. How does that translate as turn him into a dragon!"

As yuzu reprimanded the dragon king, the large purple dragon some how managed to shrink in on himself.

"It was Ddraigs idea." The blaze meteor dragon muttered.

"Ohhhhh, Ddraig said it so it must be a great idea. Need I remind you that fool got himself trapped in a sacred gear for the rest of eternity. I don't think we should be going to him for advice."

"Well that's very rude. It's not my fault god wanted to screw me over. As I recall it, I was just minding my own business, winning a fight with the white one, when suddenly my life was ruined. Thank you very much."

Ajuka ignored the three opting to instead address the boy, who was playing with a ball of golden light.

"I see you were able to make progress with your angelic magic, huh Issei."

Once spoken to, issei looked up from the ball, which suddenly disappeared in his hands.

"Yeah kind of. So far I can only use my angelic magic in small portions. When I too much I get a bit of a headache. As for my demonic magic I've only been able to conjure my aura. Other than that I haven't made much progress with it."

Ajuka took in the new information he received. So far it all sounded good. He also wasn't worried about the Issei's inability to use his demonic magic, largely due to the fact that he already knew why he couldn't use it effectively.

It was at this moment that Ajuka appraised Issei's new appearance. The changes were easily discernible from how he originally looked. What once used to be flesh was now dark red scales, covering Issei's arms, legs, and torso, leading all the up to just below his neck. Issei's hair seemed even spikier and the horns that were once no bigger than two inches, now stood six inches long and looked much more durable. Issei's hands and feet looked humanoid, but they had sharp nails and were also covered in scales.

"Very good Issei, you've already came so far in such a short amount of time. Now let's see how much you've improved in combat shall we.

As Ajuka finished his sentence he removed his cape and assumed a fighting stance.

"A-Ajuka! Are you serious. What if someone gets hurt?"

"Oh he'll be fine Yuzu. He's been training with dragons for three months, if that doesn't make him tough then nothing will."

Ajuka looked back at issei to see that the young boy has taken a fighting stance, similar that of a boxer with his right foot forward. The maou could detect the slight nervousness coming off of him. However the nervousness was overshadowed by the excitement in the boys eyes.

A smirk formed on the satans face as he prepared to spar with the young boy.

'You've changed so much in such a little time my boy. I'm curious to see how you will progress in the future.'

"Begin!" Ajuka yelled causing Issei to charge towards him faster than a bullet. Ajuka put his arm up to block the first punch Issei threw. To the man's surprise the punch actually backed him up a bit. To counter this Ajuka grabbed at Issei's attacking arm and threw him into a nearby mountain.

The young sekiryuutei quickly readjusted himself in the air, and lept off the mountain. Ajuka was impressed as Issei came back even faster, attempting to throw a roundhouse kick at him. Ducking under the attempt ajuka threw an uppercut, but was surprised when a long scaly tail grabbed his arm before he hit his target. Before the satan could retract his arm, Issei used the opened guard to his advantage, driving a vicious hook Into Ajuka's rib.

The boy was strong enough to drive the satan back a bit further.

"Very good Issei, but now let's see how you handle 10 percent of my full strength." As the maou finished his sentence, he flared his dark green aura pushing issei back off of him.

Issei assumed his fighting stance once more getting serious, he began to charge up his power.

"Let's go Ddraig. I know we're outmatched but I still want to give it my all."

"That's the spirit partner!"

Upon declaring his motives, a green jewel appeared in the center of the boys chest. From it a single word was uttered.

"BOOST!"

Ajuka listened curiously, as the word was yelled upwards of ten times consecutively.

'How strange. It seems like the sacred gear merged with his body. It doesn't even seem to need the ten second break in between any longer. And his power has increased significantly. I may need to go up to 13% percent instead.'

"Issei, How long do you think you can sustain that power for."

Issei contemplated the question for a second then answered.

"Maybe five minutes. Six if I push my limits."

Ajuka chuckled at the response. At just five years old, the boy could contend with almost all high class devils. Even if it was only for five minutes it was still an impressive feat.

"Alright then, let's not waste any time. Come at me with everything you got. I want you to act as if your trying to kill me!"

Finishing his sentence, Ajuka charged at Issei faster than the boy could perceive. Raising both of his arms in the air he bought them down in a slamming motion.

Issei had to use all four of his arms to block the attack. Ajuka noticed a bright red light coming from the boys mouth, and felt a strong heat oozing off the boy. He quickly jumped back to evade a pillar of fire that erupted from the boys mouth into the sky. Once the pillar started to make its way towards him, Ajuka aimed a blast of demonic magic at it, causing the two attacks to collide.

Once it seemed like his own attack was starting to lose to the flames, Ajuka used his other hand and created a swarm of demonic flies to attack Issei. The flies did as ordered and interrupted the boys attack by biting and stinging at him.

"Ouch, ouchie! That's not fair uncle Ajuka! Your cheating!"

"In a fight of life or death Issei, there's no such thing as cheating."

To be rid of the flies Issei created an orb of green energy about the size of a marble. From the center of his chest the word 'Dragon Bomb!' was yelled. An explosion was let off right next to Issei's face killing all the flies and leaving him relatively unharmed.

Before Ajuka could be too surprised by the event, a golden light started to shine in front of him. It was so bright that it almost blinded him. When it died down Issei was holding a sword and shield of light in his two bottom hands, and a war hammer and axe in his top two. On the boys back sprouted four dragon wings, but they were very different from regular dragon wings. The left two were black and leathery while the right two were golden. In addition to the changes, Issei's normal hazel brown eyes were no longer visible. What took its place was fire that didn't seem to block his vision.

Before Ajuka could even react to the new changes, he was ducking under a slash from the boy's axe of light. For the next two minutes Ajuka and Issei were throwing fierce attacks at one another. The two were moving at such a fast pace that only the most trained eyes could follow them.

Ajuka immediately took notice of issei's fighting prowess. He seemed to be a natural when it came to physical combat. Expertly mixing in faints, and awkward rhythm to throw the satan off. His training with dragons has also taught him to use every part of his body while fighting. On multiple occasions Ajuka would have to move away from Issei's tail so it wouldn't grab hold of his legs or arms.

The final minute of the battle was soon upon them and Issei's breath was ragged.

His hammer and axe were destroyed in the fight, leaving only his sword and shield. Ajuka however was unscathed and wasn't even sweating. Not one of Issei's attacks had landed clean after his transformation. Granted the satan did jump up to sixteen percent of his full power.

"Get ready uncle Ajuka because I'm gonna give this last attack everything I have!"

"Explosion!" The green jewel yelled from within the boy's chest. Ajuka watched as Issei's power skyrocketed and his angelic and demonic aura flared stronger than it did the whole battle.

The boy flew off into the sky and began forming a giant green ball of energy. It was four times the boy's body, and seemed to grow bigger.

Ajuka readied his own attack to counter. As the ball started to get closer towards Ajuka, he fired his own attack. Then immediately he regretted it. Just as the satan's attack neared the energy ball, it made a beeline for Issei. The satan heard the words "Recycle!" Right before the ball disappeared into the boy. Confused and still powering his own attack , Ajuka quickly realized that it was another feint.

The maou watched with surprise as Issei made a dash towards him, evading his attack all together. He didn't even have time to change tactics before the sekiryuutei was right before him with his hand reared back. All Ajuka did was smirk as a scale covered hand made contact with his face and launched him towards a mountain.

Before the satan could make contact with it, he redirected his momentum, using his 12 devil wings to take off into the sky. From this new angle he got a view of the battlefield. Many large mountains surrounding them had been broken and shattered from their battle. The ground had burn marks from Issei's explosions and fire.

In the heat of battle Ajuka hadn't even noticed that a dozen or so dragons had flown over to watch the battle between the two. As he descended back into the battlefield Issei stood exhausted.

The word "BURST!" was yelled from the green jewel in Issei's chest before it disappeared along with the boy's wings. As Issei was going to collapse into the ground, the maou scooped him up into his arms.

The dragons watching the fight erupted into cheers after the battle they witnessed. Some even shoot streams of fire into the air.

"Alright everyone calm down. As for you Issei I'm very proud of how far you've come. When you first came to me you were just a pipsqueak. Now you're on your way to becoming a great warrior. I do hope you will come back to train with us. You are always welcome here, little hatchling."

A smile spread across the boy's face as he moved out of Ajuka's grasp. Upon reaching the ground the sekiryuutei slowly walked to the massive purple dragon. When he finally stood in front of the dragon king he bowed before him.

"Thank you for everything Tannin-sama. I still have so much to learn from you, so I will be back soon."

As they said their goodbyes, Ajuka opened up a teleportation circle to his manor. When the light faded the two devils and the hybrid stood in front of the doors to the castle.

Issei pov

Issei sat in a study room across from Ajuka and his aunt Yuzu. The couch he sat on felt like a cloud, but then again any couch would feel comfortable compared to the rocks on the dragon mountains.

"What training will I be doing today uncle Ajuka?"

Ajuka took a seat in front of the big mahogany desk.

"Today we will be training your mind. Yuzu has informed me that you haven't yet received a formal education. I expect that your reading level is far behind what it should be but that isn't your fault. We will be starting on the basics of devil history."

As Ajuka began explaining the 72 pillars and the Great War. Issei learned of the four satan clans and was curious about something.

"You mentioned the Asmodeus clan. Isn't that the one we're from?" He asked Yuzu, who gave him a rather strange and unreadable expression.

"It's rather difficult to explain really. My Father was indeed a member of the Asmodeus clan, yes. But after taking a human wife and producing two half breeds, which would be me and your mother, he was something of an outcast. As the Great War was reaching its climax though, your mother Miki met an angel, and the two fell in love with one another and had you. After that well, to put it simply none of us were allowed to carry the name anymore, as declared by Lucifer himself. After he attempted to kill your parents of course." The explanation caused Yuzu to dawn a gloomy expression.

Issei didn't know how to feel about what he just learned. He knew he should be sad but he didn't know his parents enough to feel that way. If anything he just had more questions.

"So… who is my father exactly? I never learned who he was beyond him being an angel, and going by the name Gorou Hyoudo." Asked the sekiryuutei. He recalled the times spent in hiding with his aunt asking about his parents and her promising to tell him more soon.

"Gorou Hyoudo is a name that Gorou gave himself. Originally he was one of the ten great seraphs, known as Metatron. He served very close to God himself. After heaven learned of his relationship with Miki they banished him, forbidding him to ever return. To add to the punishment they stripped him of his name since it was gifted to him upon being turned into an angel."

There was still one thing that confused the young abomination. Which prompted him to ask his final question about his parents.

"I thought that when an angel committed a sin, they were outlawed and turned into fallen angels. How come I have golden wings instead of black ones?"

"That Ise dear, is unclear. It's a mystery why Gorou never fell even after committing one of the greatest sins of all. I suppose that would be something we'd have to ask him if he was still around to answer. All I know is after both Miki and Gorou were banished, attempts to take their lives were done regularly. It was ultimately a devil who took them out, but I'm not sure which one. I saw my sister Miki dead but peculiarly I never found Gorou's body."

"Do… do you think he's still out there?" Issei asked his aunt, with a glint of hope in his voice. Her sad expression worsened before she finally got the nerve to answer.

"I want to believe it, but I highly doubt it. While I found no body, I did find twelve severed wings and his blood right next to Miki. I know this must be hard for you to take in Ise. It's hard for me to tell you. But I felt you deserved to know the truth."

The boy sat quietly for a few minutes. Saying it was a lot to take in was a huge understatement. For years he was left in the dark about his parents and his lineage and now the truth came pouring out. He finally spoke.

"It's fine auntie. Well it's not fine but I needed to know. I can't explain how I'm feeling really. But I do know this. All those bullies who took my family away will never get the chance to do it again. I'm the sekiryuutei and one day im gonna be so strong they won't be able to touch me! In fact I'm gonna go train right now!"

For the first time that morning Yuzu finally smiled. Ajuka uncharacteristically cackled at the boy's resolve.

"I'm sure you will, Issei but don't be too arrogant now. Overconfidence has been the downfall of many sekiryuutei before you. Also I hate to burst your bubble but we haven't even begun your other schooling yet. Need I remind you, you still don't know how to spell your own name."

Ajuka chimed in causing Issei to deflate.

" I do know how uncle Ajuka. It's spelled 'Esay Heyodo…o?" The last O coming off as more of a question than an answer. Yuzu face palmed as Ajuka smirked.

"Most definitely not. Boy do we have are work cut out for us."
