Earth - Barren Wasteland
Issei fought to keep his breathing steady as he stared at the ground, trying in vain to suppress the tears threatening to leave his eyes. His transformation had dissipated the moment he left the Underworld, but the young man didn't care about that.
He couldn't go home now. He knew he currently wasn't in his right state of mind.
He stood on top of the mountains in the wasteland, and fell to his knees as he gritted his teeth. Despite himself, genuine tears started to erupt from his eyes. No matter how much the fury within him blazed, no matter how close he was to losing his sanity, he couldn't deny the severity of what he'd just done.
He had killed someone.
He'd never imagine that he would be angry enough to actually commit murder. It wasn't like him.
Issei's body trembled from the anger and confusion deep within himself. He wrapped his arms around his body, and shook heavily from what he'd just done. The image of Riser slowly disintegrating into nothingness burned in Issei's memory.
The young man shivered as he looked up at the clouds. He was deathly silent for a few moments, before his pupils and irises suddenly constricted.
"AAAAAAAAHHHHHHHHHHHHHHHHHHHHH!"
Issei screamed at the top of his lungs in fury and agony, his screams so intense that the mountains around him started to crumble apart. His roar screamed back at him across the atmosphere of the wastelands, causing more of the stone structures to break down.
Clouds of dust suddenly exploded and dissipated, thrown away by Issei's energy. Issei screamed and screamed, his lungs allowing his pure, unbridled wrath to unleash itself. The ground beneath him quaked, and a large crater formed as his raw energy decimated the land under him.
Issei's House
"Ise-itoko..."
Leiko looked upon her sleeping cousin as he rested peacefully on the couch.
"What happened to you? You changed."
After coming from wherever the hell she was previously, Leiko noticed that Issei had returned to his normal state, his brown hair and his soft sharp multi-colored eyes resurfacing. Immediately after, he collapsed onto the couch, earning a well-deserved sleep.
Leiko sighed as she sat on the couch.
"Who were those people?"
She had been trapped in that dungeon for a long time, and the only person she had seen was that Chinese girl. Leiko could tell that the girl wasn't human, but she still didn't know what she was.
Leiko looked over to her cousin, and her crimson-ruby eyes softened.
"Ise-itoko."
Although she was very reluctant to do so, Leiko eventually stepped out of the Hyoudou residence to get some fresh air, leaving Issei in the living room.
Suddenly, a series of shadows manifested above the ground, and they cleared away, revealing Ophis, the Infinite Dragon God. Her dark-gray eyes gaining a curious look to them, Ophis floated over to Issei.
She tilted her head, and she slowly sat on top of him, resting on his stomach. Tilting her head again, Ophis placed her finger on Issei's forehead, rubbing it gently.
She was relieved that Issei had regained his pure and radiant solar energy once more. That devastating energy surge he had earlier possessed affected her than she had expected. She was satisfied that the boy she had met a long time ago, was now back to normal.
Bringing her face close to Issei, Ophis let an unreadable smile form on her face.
"You, are mine. Back, to normal. I, like that."
Different colored eyes fluttered, and they opened wide just in time to see dark-gray eye boring into his own. Issei widened his eyes at the girl. The girl who had appeared to him eleven years ago. She was back! Sitting on top of him!
...Dressed in that same Gothic Lolita outfit!
Issei widened his eyes further as he noticed that there was two black cross-shaped tapes attached onto Ophis's chest. Shaking his head to clear his side-tracked thoughts, Issei looked up at the girl sitting on top of him in shock.
"I-It's you!"
The smile on Ophis's face seemed to widen, but it didn't reach her heavy-lidded dark-gray eyes.
"Yes, it is me. And you, belong to me. You, are MINE. Only mine."
Heaven
Gabriel sighed as she put her hand on her chest.
"His energy. It's back to normal."
She was genuinely relieved that Issei had regained the purest form of his Solar Energy structure. The power radiating from his Hell-Fire transformation had honestly worried her greatly.
"Yes, it is. Let's hope it stays that way."
Gabriel looked over at her older brother, whose green eyes lowered in a sad manner. Gabriel's eyes softened, and she looked off to the side.
'That energy from earlier. It was so catastrophic. The power he possesses greatly surpasses the power of Michael. It even far exceeds that of an Ultimate-Class Devil by a large margin.'
Her eyes gained a saddened look as she remembered visiting the boy in his room eleven years ago.
'He was such a sweet little boy. What could have caused this change?'
In the Underworld
A beautiful girl with long, black hair tied in twin ponytails narrowed her violet eyes as she contemplated. She was one of the Devils who had watched the fight between Issei Hyoudou and Riser Phenex.
The girl normally dressed in magical girl's clothing, but just for that one occasion on what happened earlier, she now wore a formal navy blue dress-shirt with a black skirt. Her violet eyes narrowed in concentration.
