Summoner: Monster Girl Harem!

Vincent regained his senses from the strange dream with all his women and close friends around him.

'Ah, finally back...'

"Are you alright, darling?" Silvari's soft voice sounded as she entered the room with a hot drink of tea and some snacks, placing them on the living room table.

He reached out to the warm cup of tea with a slight smile, feeling like he knew Efrita and Silvari much better now. 'I am glad to be back; these girls are so....'

Vincent felt warm, surrounded by all of his lovers. However, suddenly the moment he poured some milk into his tea, a throbbing pain filled his head as if someone were calling out to him, demanding his presence.

'What the hell is going on?' Vincent thought, trying to shake off the strange sensation. But the pain only grew worse, the voice louder and more insistent.

"Come to me, Vincent," the mysterious female voice whispered in his ear. "Forget everything else and find me. I'll show you true power, blissful pleasure. Just give in to the darkness inside."

Vincent tried to resist the temptation, but the voice was too seductive, too alluring. Silvari, his ice spirit, tried to chase after him, but Vincent turned back, gripping his head in pain and pushed her back with a pleading look.

He rushed out the door without a word, leaving his confused lovers behind.

"No," Vincent muttered to himself. "I can't let the darkness take control. I have to stop it, no matter what the cost."

As Vincent struggled to resist the call, he could feel the darkness growing more potent, threatening to consume him entirely. He knew he had to find the source of the voice and stop it before it was too late, but he did not know where to begin. All he knew was that he couldn't give in to the temptation.

Vincent's face grimaced in pain as he rushed through the narrow, winding streets of Verina. He stumbled and knocked people aside as he made his way towards the south exit, trying to resist the mysterious voice that kept calling out to him.

"What the hell is going on?" Vincent thought, his head pounding with the voice's insistent whispers. "I can't shake this thing off; it's like it's inside my head."

"Come to me, Vincent," the voice whispered seductively. "Forget everything else and find me. I'll show you true power, true pleasure. Just give in to the darkness inside you."

Vincent tried to block out the voice, focusing on the sights and sounds of the bustling town around him. Verina was a chaotic, bustling place, filled with merchants selling their wares, beggars and pickpockets lurking in the shadows, and all manner of people rushing about on their daily business.

He started in the slums where he lived, stepping in muddy puddles and knocking people down as he stumbled through the crowded streets. The slums were dingy, cramped places filled with crumbling buildings and narrow alleys. The smell of sewage and garbage hung heavy in the air.

Then Vincent moved into the merchant quarter, his body rushing towards the south exit of the city. The merchant quarter was slightly more upscale, filled with brightly-coloured stalls and bustling crowds. A smell of spices and exotic goods filled the air as he rushed past with rapid steps.

For some reason, his body seemed to be heading towards the south. He hoped it was somewhere other than the dungeon near him but was soon let down.

As he approached the entrance to the abandoned dungeon, Vincent hesitated, trying to hold onto his sense of self. His spear, Raizel, tried to calm him inside his mind, her sultry female voice contrasting with the mysterious one that kept calling out to him.

"Vincent... This is a one-way path... Now is your last chance to return to that wonderful harem life!" Raizel pleaded. "You... Don't need to do this..."

Surrounding his vision was a gigantic expansive building which looked like an old cathedral with broken windows, burned pews and a rotten floor. His eyes narrowed, looking at the strange place as his entire body throbbed with both delight and anguish. 'What I seek is inside... The thing that calls me!'

But Vincent couldn't shake the feeling that something was pulling him towards the abandoned dungeon, something dark and powerful that he couldn't resist. He could even hear a woman calling out to him, urging him to follow the voice and find her.

"Raizel, thank you for the concern." He said with a deep rushed voice before his body naturally entered his Wrath sin form; since he no longer needed to submit to the sin, it no longer cost anything other than making all attacks cost double the stamina and anima to cast.

Finally, with a grimace of determination, Vincent stepped through the water-like portal and followed the voice into the abandoned dungeon. His sclera had turned a deep, inky black, and his pupils glowed with a golden-red light.

Vincent stepped inside, his right hand flicked out, causing Raizel to materialise; no longer could he be stupid and only prioritise one style in the dungeons. He could sense it inside this dungeon; the power of the monsters here relied not on some system but on the person who waited for him at the bottom.

As he descended deeper into the dungeon, Vincent could feel the darkness inside him growing more assertive. He knew he had to find the source of the voice and stop it before it was too late, but he had no idea what he would find in the depths of "Bismark Cathedral."

A woman with long, messy black hair lay sprawled over broken rocks, crushed corpses and a strange monster that used to rule this dungeon. "He's here, the brother that mother told me about." Her smile is beautiful, with two tiger-like fangs.

However, this was the end of her appealing features; two thick horns protruded from her head and seemed to hum while crackling with lightning and sending jolts out whenever her emotions spiked.

Tight muscles formed along her naked body; she didn't wear any clothes her skin seemed to alternate between a velvet red and snow white. The girl stood around 5ft 3" tall, with a slightly voluptuous body and a huge perky ass squished down on the rocks and looked tasteful and attractive.

Suddenly her body shifted, opening her closed eyes to reveal a black sclera just like the current state of Vincent; hers were glittering star-like dots while her thin narrow slit darted around the golden iris that seemed to glow and leave a light trail when she moved.

"Oh brother, when will you come to me? Astaroth has awaited meeting you for so long; she killed the annoying old man and came down here earlier! You won't die after a few punches like him, right?" Astaroth said as she punched out, a loud snap from her quick punch followed by a wave of force that punched a deep fist-shaped crack into the wall two metres away.

Her tight muscles bulged for a moment in her arm before they condensed and shrank, her breath calm and the fist a mere reaction for her.

Inside her hand was a crumpled picture of Vincent from several years ago, with various stains on it as if she treated it like a treasure. "Vincent, I want to fight you so badly. Mother always praises only you... Hehe, what do your guts taste like? I can't wait, brother~ hehe!"

A long black tail with white scales swayed behind her; sometimes several golden eyes identical to her own would flicker and open along them and stare into the void.
