Soul King(DxD)

Phoenix 13

 Issei: So Ddraig is in my boosted gear?

 Y/N: That's exactly what I want to teach you, Issei. The boosted gear is where Ddraig's powers reside, not just the boost, but all of his other abilities as well. You Issei, your destiny since being born with boosted gear has never been that of a normal human, or you would die or become a half-dragon.

 Issei: If that's true then how do I go about learning all the boosted gear skills?! Even if I need to sacrifice my limbs I will!

 Y/N: Only Ddraig can teach you how to use his powers, and for that, I'm going to teach you a skill. It's called Jinzen, a method of meditation used to step into consciousness itself, I use that when I want to upgrade my powers, and you will do the same, I will teach you Jinzen and that will allow you to talk to Ddraig.

 Of course, it wasn't easy, Issei's overactive libidinous mind never allowed him to spend a few seconds with his eyes closed without thinking about breasts. But a deal was made between them, every time Issei started thinking about something perverted...

 Y/N punched him in the face.

 It's not hard to know when Issei starts thinking about something perverted, his face contorted in that typical expression that is disgusting.

 How many punches have passed? The shinigami was getting disappointed, Issei needed to focus on emptiness and calm to get into his on mind where Ddraig was present, but he only thought about breasts, breasts, breasts, or more breasts.

 Y/N was going to finish practice there, with no results that night, but he noticed, the teenager was quiet and expressionless for a long time, the rest of him had never squirmed for a moment since that session. This kid did it.

 *Current Time*

  Issei: I needed to take a lot of hits that night, but I finally managed to get to the source to strengthen myself! Ddraig, Unleash your flames!

 Dragon Flames Unleashed!

 And with the command, the crimson flames escaped the boosted gear, uncontrolled and with great power, the allied group itself retreated so as not to be caught amid so much brutal heat.

 Kiba: Those flames are too strong, my flame delete wouldn't be able to cancel them.

 Rias: Issei! Watch out for those flames, don't tell me Y/N just taught them to release them out of control.

 Issei: None of that, President! Ddraig taught me to release them, Y/N taught me to use them with control!

 And the flames calmly calmed down, already stopping to spread and burn the entire roof of the building. True skill made itself present when the flames retreated and pooled in the young man again, Issei controlled the flames with effort, placing a hand on sacred gear while letting a roar of effort erupt.

 The dragon's so powerful flames gathered all in Issei's body before manifesting with force in the arms and fists, then the two legs.

 Fists and legs covered in the dragon's flames, so intense and red that they showed their enormous power, covered in the aura of heat capable of melting the floor where the feet were. Issei went into a combat stance, both fists raised and leg back ready to step forward or be used for a kick.

 And finally, with a glowing green gaze ready for combat. The next words came out of him.

 Issei: Flaming Body of the Dragon Emperor.

 Riser for the first time felt his nervousness wanting to take over, the dragons' flames, immensely more powerful than the Phoenix's, those fists covered in a red fire can deal severe enough damage to cost a lot of demonic power to heal.
