The Devils shielded their eyes from the brightness, and then as the light faded, they removed their arms from their eyes. Riser opened his eyes, and he gasped as he flew back.
"His appearance! He's changed again!"
The young man he was fighting, his appearance had changed once again. Issei's hair was now a night-black color, and was no longer as spiky as his Solar form, but was more upright. His left eye had regained its doe-brown color once more, however his right eye did not retain its yellow-orange color. His right eye was now a black-grayish color. His facial features were also more pronounced, giving him a look of intense focus.
Riser looked on in terror at the massive surge of explosive power radiating from Issei.
'He...he absorbed my flames! That's impossible!'
The Student Council Room
"H-he transformed again!" Saji exclaimed.
The members of the Occult Research Club and the Student Council all looked on in amazement and horror as they witnessed Issei go through yet another transformation. Rias's body shook as she felt Issei's power explode once more.
"H-he's even stronger than before!"
"He absorbed Riser's flames!" Tsubaki said as her stoic expression disappeared completely.
"This is completely unprecedented!" Sona exclaimed.
Azazel's Headquarters
"This can't be! He transformed again?!" Raynare shouted.
"Hmm. Yes, it seems so. By absorbing the flames of a member of the Phenex Clan, Issei achieved another form on his own. Those black flames...they look like Hell-Fire." Azazel mused.
"Hell-Fire?! But he's not a Devil!"
"That's true."
Azazel gained a serious look as he placed his hand under his chin.
'He's not a Devil. However, the solar energy within his body...it changed when he absorbed Riser Phenex's flames. There are many aspects of our Sun. However, the most important aspects, are the Purifying/Nurturing and the Destructive Aspects. Hmm. It seems that Issei's second transformation is the combined result of his rage, therefore signifying the destructive aspect of the sun, and Riser's flames. A Hell-Fire Transformation. Hell-Fire Issei.'
Azazel smirked as he peered at the magic viewing portal, paying close attention to the black aura of blazes around Issei.
'Hell-Fire, the mystical flames of hell. It can cause excruciating pain upon contact instead or even cause instant death. Who would've thought that Issei could achieve a transformation like this, just by absorbing a Phoenix's flames?'
"This boy is very interesting." The male Fallen Angel mused.
Heaven
Michael, The Leader of the Angels, gulped down a sharp and nervous lump in his throat as he tried to endure through the great power surge that had just manifested itself.
'How can this boy possess so much power?'
"Mmm~~~"
Widening his green eyes, Michael turned around to face his sister Gabriel, who had her hand on her chest once again. Her beautiful face had morphed into a expression of great sadness.
"This cataclysmic surge of power. It's from that young boy. It's so suffocating."
In The Dimensional Gap
Ophis lifted her hands and put them to her cheeks as an expression akin to worry and shock formed on her face. The power she had felt from that boy, it had increased explosively, but yet it had also obtained a more...distinct aura.
"There is something wrong. The spawn of the Sun. He has undergone through another transformation."
Great Red looked down at Ophis with an almost confused expression on his face. Out of all the moments he has begrudgingly spent time with Ophis, he had never seen her like this before. She looked so shocked.
"Ophis."
"The boy. He is different. More powerful, yet destructive."
This bothered her greatly. The radiance and purity of the solar energy the boy had possessed is what fascinated and attracted her to him in the first place. But now this power...it was absolutely devastating.
"I, do not like this. Not, at all. He worries me."
Great Red rose his head in confusion, and huffed.
"Wonder what poor schmuck made this kid mad?"
Ignoring Great Red's comment, Ophis narrowed her normally stoic gray eyes darkly.
"The boy. He, is MINE. He, belongs to ME. Only me. Someone, hurt him. They, hurt him. They hurt, what is mine."
Great Red blinked in surprise at the foreign tone Ophis had used in speaking her thoughts.
'Never thought I'd see Ophis so possessive over someone.'
Arena in the Underworld
"Riser!"
Riser widened his eyes at Issei. The young man's voice was deathly cold. He felt a chill in his spine as he tried to endure Issei's icy stare.
"Bringing me here was your first mistake." Issei began.
Golden bolts of lightning sparks surrounded Issei's blackish aura. Riser stiffened at the raw intensity of his opponent's power.
"Belittling me was your second mistake."
The Phenex male could only stare at Issei in horror, his mouth agape. Issei narrowed his eyes and clenched his fists, giving Riser a fierce glare.
"Your third mistake was attacking my cousin."
The blackish aura with golden sparks surrounding Issei flared outwardly, prompting Riser to back away from the intensity. The Phenex male paled as he noticed the ominous death glare Issei was giving him.
"And once I'm through with you, it will be your last."
Unknown Location
"Albion, do you sense it?"
(I do.)
"Do you believe the other Heavenly Dragon has awakened?"
(No. I don't recognize Ddraig's presence within the power you are sensing. The power seems to be unique in its own. On a much different scale compared to Ddraig's.)
A handsome young man with dark silver hair and blue eyes, stood up from his spot as he crossed his arms. A disappointed scowl formed on his face as he looked off to the side.
"Humph. And here I thought I would finally have the chance to meet my rival. What a shame."
(Never before did I ever expect myself to say this, but do not cloud yourself in arrogance, Vali.)
"..."
(And might I remind you, although I was sealed in a Sacred Gear, there is a chance that Ddraig was not. For all we know, the bastard's sealed in something else. After all, we were both apart when we were sealed. I have not seen Ddraig in a long time. But I feel that his return is near.)
"Tch."
Arena in the Underworld
With pools of Hell-Fire covering his entire body, Issei narrowed his eyes and charged at the Phenex male who had wronged him so. As he got closer, Riser gritted his teeth and charged back in retaliation, lifting his feet up in an attempt to kick Issei.
Issei narrowly dodged the attempt, and he sent a devastating punch to Riser's stomach. The Phenex male widened his eyes in pain and held his abdomen. However, Issei was not done yet.
Flaring out his aura composed of Hell-Fire, Issei sent a barrage of kicks and punches, the Hell-Fire augmenting his attacks. Riser coughed out blood as a result of Issei's attacks, and he coughed out more when Issei grabbed his head and slammed it down into the ground.
Riser narrowed his eyes and tried to get up, before he felt a foot planted on his head, preventing him from escaping. Shuddering rapidly, Riser attempted to move his head up, and looked up to see Issei silently glaring down at him.
"P-please don't do this! T-the girl! The one with the silver hair! She's alive! I swear it!"
Issei's expression didn't change, but that only prompted Riser to plead for his life once more.
"IT WAS ALL JUST A RUSE! I just wanted to see how strong you were! Your cousin is still alive! I swear it!"
"..."
Suddenly, an energy sphere consisting of Hell-Fire began to manifest and cover Issei entirely. Black flame-like ribbons of energy spiraled around his body. Riser paled at the raw intensity of Issei's energy, and looked up again to see Issei with a calm look on his face.
"That won't save you."
