Returning Back to Underworld  

Izashi, his mind still buzzing from his encounters with Grayfia, Irina, and Xenovia, decided a change of scenery was in order. He focused his power, visualizing the Gremory Mansion in the Underworld. In a blink, he teleported, the familiar gothic architecture materializing around him.

He found himself in the main hall. It was mostly deserted, save for one figure seated in a plush armchair: his father, Zeoticus Gremory. 'Well, well,' Izashi thought, a smirk tugging at his lips. 'Looks like dear old dad is still moping around.'

Zeoticus looked up, surprise evident on his face. He hadn't expected Izashi to appear at the mansion, especially not at this hour. "Izashi?" he asked, his voice tinged with confusion. "What brings you here, son?"

Izashi's expression remained unchanged, a cool, detached gaze that he usually reserved for his underlings. "It's my mansion, Zeoticus Gremory," he replied, his voice flat and emotionless. "I don't need a reason to come here."

Zeoticus internally grit his teeth. The casual disrespect, the blatant disregard for his authority, it was infuriating. He wanted to lash out, to remind Izashi of his place, but he knew it was futile. He had lost. He was no longer the head of the Gremory clan. He was nothing.

'I can't believe this brat,' Zeoticus thought, his fists clenching. 'He treats me like dirt. Like I'm nothing more than a servant in my own house… or rather, his house now.' He forced a neutral expression onto his face, refusing to give Izashi the satisfaction of seeing his anger.

Izashi, however, was perceptive enough to pick up on the subtle cues. He could practically read his father's mind, anticipating his every thought, every emotion. "What?" he asked, his voice laced with mock concern. "Are you unsatisfied? Not my problem. We had a fight, and I won. I got this mansion, this position, because of my power. You were simply unworthy of it."

He watched as Zeoticus's face flushed crimson, his jaw tightening. 'Oh, this is too easy,' Izashi thought, a cruel smile playing on his lips. 'He's practically begging for more.' He decided to oblige.

"And let's not forget about Venelana, shall we?" Izashi continued, his voice dropping to a low, suggestive murmur. "She seems to be enjoying her… new arrangement quite thoroughly. I must say, she's quite the woman. Very… accommodating."

Zeoticus's face paled, his eyes widening in horror. The mention of his wife, the blatant disrespect towards her, it was like a knife twisting in an open wound. The memory of Venelana's voluptuous body, now enjoyed by his own son, was a constant source of torment for him.

'That little…!' Zeoticus thought, his mind reeling. The image of Izashi touching Venelana, kissing her, possessing her, it was too much to bear. He felt a wave of nausea wash over him, his stomach churning. He wanted to vomit. He wanted to die.

Izashi, sensing his father's distress, pressed on, relishing his discomfort. He knew that the topic of Venelana was a sore spot for Zeoticus, a source of deep shame and humiliation. He enjoyed twisting the knife, reminding his father of his utter defeat.

"Of course," Izashi continued, his voice laced with mock sympathy. "I understand it must be difficult for you. To know that your own son is… satisfying your wife in ways you never could." He paused, a cruel smile spreading across his face. "But then again," he added, his voice dropping to a whisper, "you were always rather… inadequate, weren't you?"

Zeoticus's mind was a whirlwind of conflicting emotions. Rage, shame, despair, they all battled for dominance within him. He wanted to scream, to lash out, to attack Izashi, but he knew it was pointless. He was no match for his son's power. He was nothing.

'I can't take this anymore,' Zeoticus thought, his mind teetering on the edge of despair. 'I can't live with this humiliation. I should just… end it all.' The thought of suicide, a dark and tempting escape, crept into his mind.

Izashi, sensing the shift in his father's thoughts, decided to change the subject. He didn't want Zeoticus to actually kill himself. That would be too boring. He preferred to keep him around, to use him as a constant reminder of his own dominance.

"Enough of this idle talk," Izashi said, his voice regaining its usual coldness. "For now, go and place the strongest barriers around the courtyard…" He turned around, dismissing his father with a wave of his hand. "I want it ready in 15 minutes…"

He didn't even bother to look back, knowing that Zeoticus would obey without question. He had broken his father, crushed his spirit, and now he could command him like a puppet. He returned to his own room, a bottle containing the power of Ophis, the Ouroboros Dragon, waiting for him.

Izashi stared at the bottle containing Ophis, the small dragon coiled within. He knew unleashing its power now, within the confines of the mansion, was a terrible idea. The sheer dragonic aura would be overwhelming, likely causing significant damage and alerting everyone in the vicinity. 'Not exactly the subtle approach I'm going for,' he thought dryly.

As he touched the bottle, a subtle vibration resonated through him. The golden sphere within his core, the mysterious source of his power, was reacting to Ophis's presence. It wasn't a violent tremor, just a gentle hum, but Izashi could definitely feel it. 'Interesting,' he mused. 'Looks like these two are more connected than I initially thought.'

He knew he hadn't fully grasped the extent of the golden sphere's power. He was strong, undeniably so, but he still couldn't break the dimensional barrier and enter the Dimensional Gap. That realm, home to the strongest dragons, remained beyond his reach. 'Still got a ways to go,' he thought, a hint of frustration creeping in. 'I need more power. Much more.'

But he was certain of one thing: integrating Ophis's power would be a significant step forward. It was a gut feeling, an instinct honed by countless anime and light novels from his past life. 'Absorbing powerful beings always leads to a power boost,' he thought, a smirk tugging at his lips. 'It's practically a law of the universe.'

As long as he could control the energy, the integration should go smoothly. It was a risky endeavor, no doubt, but the potential rewards far outweighed the dangers. 'Great Red, Ophis,' he thought, his eyes narrowing. 'Be prepared. I am coming for you both. I shall surpass you both.'

While waiting for the barriers to be erected, Izashi decided to indulge in a little… entertainment. He summoned several succubi, recently recruited by the Gremory family. They were all stunningly beautiful, their bodies crafted to tempt and entice. 'If I have to wait, I might as well enjoy the view,' he thought, a mischievous glint in his eyes.

The succubi materialized in his room, their eyes widening slightly as they took in Izashi's imposing figure. They quickly composed themselves, however, their professional smiles returning. They knew their role, and they were eager to fulfill it.

"Lord Izashi," one of them purred, her voice low and seductive. "You summoned us?"

Izashi nodded, his gaze sweeping over their voluptuous forms. "Indeed," he said, his voice laced with amusement. "I require some… distractions."

The succubi exchanged glances, a mixture of excitement and anticipation flickering in their eyes. They knew what he wanted, and they were more than willing to provide it.

"As you wish, Lord Izashi," another succubus said, stepping forward. She began to slowly undress, her movements graceful and alluring.

Izashi watched, a smirk playing on his lips. He didn't just want them to stand there; he wanted to enjoy their bodies, to feel their soft skin against his. 'Might as well have some fun while I wait,' he thought, his eyes gleaming with desire.

He reached out, pulling one of the succubi closer. He kissed her deeply, his tongue exploring the depths of her mouth. The other succubi watched, their eyes filled with a mixture of envy and excitement.

Izashi continued his exploration, his hands roaming over the succubus's body. He squeezed her breasts, teasing her nipples, eliciting soft moans from her lips. He then moved on to the next succubus, and then the next, giving each of them his undivided attention.

He spent the next few minutes thoroughly enjoying their company, his mind momentarily forgetting about Ophis and his plans for the future. He was completely immersed in the present moment, indulging in the pleasures of the flesh.

As he was in the middle of enjoying the company of the succubi, a polite voice called out from outside his room. "Lord Izashi," the voice said, belonging to one of the maids in the Gremory Mansion. "The barriers are prepared."

Izashi sighed, pulling away from the succubi. He looked at them, their bodies flushed, their breaths coming in ragged gasps. "That's all for now," he said, his voice regaining its usual coolness. "You may leave."

The succubi nodded, quickly gathering their clothes and disappearing in a swirl of demonic energy. Izashi adjusted his own attire, then headed out of his room. He made his way through the mansion, heading towards the courtyard where the barriers had been erected.

As he walked, his thoughts returned to Ophis and his plans for the future. He knew that the integration would be a challenging process, but he was confident in his abilities. He was determined to become stronger, to reach the pinnacle of power.

'Great Red, Ophis,' he thought, his eyes narrowing. 'I'm coming for you. And when I do, I will be ready.' He reached the courtyard, the powerful barriers shimmering around it, ready to contain the immense power he was about to unleash.
