Mythical Slayer: Mythical Girls Contract

Kai accepted the deal with Lilith.

If her request was to meet with Abe no Seimei in his dream, he didn't need to hesitate to take it.

After he replied that he would accept her deal, the Succubus Queen beamed with a smile.

"Excellent!" She shouted with a tone full of happiness. "Well then, let's go to my residence. Ah, only the new Ruler, please."

At her words, Ao narrowed her eyes, clearly displeased.

Amber also didn't look too happy. As for Ibaraki, she tried to hold Shuten Douji back from getting close to the Succubus Queen and swinging her club that suddenly appeared in his hand.

Lilith, however, only looked at them with a smirk.

"It's not like I didn't want to invite you. But my girls hate females from other races, you see? So I can't bring you there. And, in the end, it's all left to the current Ruler's decision." She tilted her head slightly and turned to Kai. "So, what's your final answer?"

Kai fell silent as the girls were looking at him. He weighed his decision carefully. This was an opportunity he didn't want to miss.

Maybe if he missed this, then the same opportunity wouldn't come again in the future.

'Getting together with the Succubus Queen without any of the girls will be a bit dangerous. I don't know what kind of person she is yet.'

Indeed, he could still protect himself. But what about when he went to the Astral Plane? He knew his body would be left in the real world, unconscious, as his soul dived inside the non-physical plane.

At the moment of his hesitation, a voice rang in front of him.

"Well, I don't mind if I can't visit my beloved soon. But aren't you in a hurry?" Lilith continued with a soft, seductive voice. "The decision is in your hand. I can wait."

"Y–" Ao was about to counteract Lilith's words, but she stopped when she saw Kai raise his hand.

"Alright. Let's do it your way." He responded in a firm voice.

Lilith's expression beamed with happiness when she heard his answer. This was a chance—a chance to get what she truly wanted.

"Fufufu, that's great!" She giggled and approached Kai. "Then let's g–

"But I have one condition." He interrupted before she finished her sentence, stopping the Succubus Queen from approaching him. "If I heard correctly, you said your girls didn't accept females from other races, right?"

"That's… indeed correct." Lilith narrowed her eyes slightly as she watched Kai's lips curl upward. "Huh?" She let out a confused voice as she watched Kai move.

He walked past the Succubus Queen and said, "So it's fine as long as they aren't seen or felt."

Ao instantly understood what Kai was about to do and spread her arms, "I am ready, dear husband." She said with the biggest smile on her face.

Amber also nodded, smiling slightly. She didn't mind that she wasn't chosen. Instead, Kai decided to choose the Dragon King, the only person who could maybe stop the Succubus Queen if she went all out.

The thousand-year-old memory failed her. Lilith had forgotten that the Ruler had a special skill to fuse with any Mythical beings he had a contract with. She immediately turned around and was about to stop it, but it was too late.

Kai had already hugged Ao and kissed her. The Dragon King's body melted like swirling water and entered his body.

It was their first fusion, and Kai felt a great power, even more bursting than when he fused with Ibaraki Douji. Physical Power, Spirit Power, and all his basic parameters were increased exponentially.

He could easily beat Panlong in this state without his training. That was how much his power increased.

"Succubus Queen." Kai turned around, and a soft smile appeared on his face. "Let us go then. I will keep my promise and let you meet Abe no Seimei in the Astral Plane if you help me enter it."

The Succubus Queen's smile turned wry as her face twitched slightly. Indeed, if he did that, then not even the other Succubus would be able to feel the Dragon King's presence. It was merged perfectly with Kai and was no different from calling Ao wasn't even there in the first place.

"And Amber, please wait for me somewhere with Ibaraki and Shuten. I will return shortly."

"Yes, Kai. We will be waiting." Amber replied with a smile without any shred of worry in her expression.

Ibaraki also nodded, releasing Shuten, who had already turned the club back to the golden microphone.

"Young man." The Oni God looked at Kai with a serious expression. "Be careful in the Astral Plane. Not even I know the danger that lies in that place."

Nodding his head firmly, Kai turned to Lilith, who had been silent since earlier, and waited for her answer.

"So, when shall we go?" He asked.

"… Right now." And was replied by Lilith with a dejected voice.

The area around the Underworld's outskirts, where the Succubus lived, was a place of otherworldly beauty and dark allure. The sky above was tinged with a sickly green glow, casting an eerie light over the streets below like any other place in the Underworld.

The buildings were tall and imposing, with sleek, modern facades and neon lights flickering above each entrance. The streets were lined with a wide variety of shops, ranging from seedy bars to high-end boutiques run by Succubus with alluring clothes.

As Kai walked through the area, following the Succubus Queen, he couldn't help but feel a sense of excitement and danger. The air was thick with the scent of exotic perfumes and the sound of seductive music, luring in visitors from all corners of the Underworld.

In the center of all that was a building. A small yet opulent apartment building with a grand entrance flanked by two stone gargoyles. The building was lit up with a neon sign bearing the name 'Lust's Den' in bold, glowing letters.

As Kai walked past the building, he could hear the faint sound of laughter and music emanating from within. He could see shadows moving behind the frosted glass windows, hinting at the hidden pleasures that lay within.

The streets around the Succubus' apartment were alive with activity, with creatures of all kinds mingling and chatting in small groups. There were dark alleys and hidden corners, adding to the mystery and allure of the area.

Despite the danger and temptation lurking around every corner, Kai was drawn to the area. The green sky above only added to the sense of otherworldly enchantment that permeated the entire district.

But he wasn't here to seek pleasure. Instead, he was here because he followed the Succubus Queen, Lilith.

They walked down the street toward the castle with an imposing structure. The walls were made of dark, rough-hewn stone, and the towers that jutted up from the structure seemed to reach toward the sky.

As they walked toward it, Kai couldn't help but feel a sense of unease.

'What is this?' He asked, to which was replied by Ao almost immediately.

[Miasma. If there is unpurified Spirit Power on Earth, there is a Miasma created by the excess feeding of Spirit Power by a succubus. It will not give any bad effect for Succubus and Devils. But for us, we will feel a bit sick when we are near a thick Miasma.]

'I see. How can we deal with it?'

[Just cover yourself with a thin layer of Spirit Power, and the effect will be mostly nullified.]

Nodding his head, Kai did as he was told, and it worked. He didn't feel uneasy anymore, and his mind steered clear.

He looked up toward the castle they were heading for.

The entrance to the castle was marked by a large, wrought-iron gate, which creaked ominously as Kai pushed it open. Beyond the gate, a long, winding path led up to the castle's main entrance, which was flanked by two massive stone statues.

Two giant doors made from solid oak, reinforced with iron bands and decorated with intricate carvings, greeted them as he stepped inside the area of the mansion.

The Succubus Queen walked in front of Kai with her hips swaying left and right, having been in a good mood because when she thought once again, the Dragon King wouldn't be able to do anything to her once they were in the Astral Plane.

That meant she would still be able to get what she desired.

'Fufufu.' She giggled in her mind. 'It doesn't matter, indeed. Astral Plane and Dream Realm are my territories.'

Stopping in front of the door, purple Spirit Power appeared from her palm and traveled toward the keyhole. A clicking sound was heard afterward, and the doors were opened.

Inside the castle, the atmosphere was no less imposing. The walls were lined with tapestries and paintings depicting scenes of war and conquest, and the air was thick with the scent of incense and burning candles.

Despite the dark and foreboding nature of the castle, there was a sense of opulence and grandeur that could not be denied. The furnishings were ornate and intricate, with fine fabrics and expensive jewels adorning every surface.

Overall, the castle was a fitting home for the powerful Succubus Queen, reflecting both her power and her dark beauty.

Lilith turned around with a big smile as she spread her arms.

"Welcome to my castle!" She declared. "And let us travel to the Astral Plane inside. I hope you will enjoy the date I've prepared for you, current Ruler."

"I will trust you with this one, Succubus Queen," Kai responded with a slick, business smile. He wouldn't let his guard down in front of this seductress. "I hope for your cooperation."

"Fufufu, of course. You can trust me."
