Kakeru could not help but to observe his surroundings with evident amazement.

The young man was in a room that could only be described as highly luxurious. The decor was clearly Victorian, with vases(that did not look cheap at all), and doors, cabinets and even parts of the beautiful chandelier hanging from the ceiling over his head being decored with or even made of solid gold. This was the room of the Queen of the dark elves, Zeragiel.

Although it was not the teenager's first time in that place, the beauty of the room never ceased to astonish him, making him feel as if he were inside a movie set centuries ago or in the house of a noble in a fantasy world (although what he experienced in Exodia Exodus until the present moment surpasses and by far any work of fiction that he had seen during his short 17 years of life).

An absolute certainty about his current situation was that being in Zeragiel's quarters was not included in his plans like, at all.

Earlier he was internally euphoric after he managed to convince her to unify Rowalrinna to his country, Hellandia, even promising to the beautiful dark-skinned elf that, as a public image, the country of the dark elves would be simply portrayed as an important ally, and not just another one of Hellandia's possession.

After these positive results that further boosted his plans for world domination, Kakeru was then planning to leave immediately for Arzheim, but he was surprisingly stopped by queen Zeragiel, who mentioned that although she accepted his proposal, she would like to ''seal'' the agreement between them in a way that she deemed worthy, and for that, she insisted for him and Hellzekter to remain in Schwarzkrone castle until the next morning.

Kakeru declined the proposal, but Zeragiel just ignored his answer, smiled and simply stated that he could wait a few more hours before leaving for Arzheim on a mission to save the elven kingdom from the clutches of the Orzelia Order. She then turned her back on him and, with a mischievous smile, ordered him to wait for her in her chambers before completely disappearing from the teen's sight as she entered an area of the castle that was completely unknown to Kakeru.

Shortly after that, he was separated from Adra, Grasha, Forneus and Satanachia.

Recalling these events, the young man stared at the air for a brief moment, Kakeru then had his attention drawn to two sharp objects of a dark brown color. Having to look down due to his enormous size when wearing the demon king's armor, he came across two dark elves, surely they were Zeragiel's servants going by the lewd maid uniforms they wore, which didn't really leave much for imagination.

The two maids then signaled for him to follow them. As he did that, the servants led him to the queen's room and asked him to wait while seated on the large bed in the center of the room. With that done, they bowed out of respect and said goodbye with polite smiles on their beautiful faces.

Now being left alone in the large room, Kakeru began to ponder what kind of method Zeragiel would use to once and for all seal the agreement they made.

''I guess it will probably be the same old thing." he murmured, remembering the kisses and caresses that took place between him and Zeragiel every single time that he and Hellzekter visited Rowalrinna.

As the young man pondered, the silver doors adorned in gold of the luxurious room opened. Kakeru's attention turned to the person who had entered, his eyes widening in reflex.

In front of him was Queen Zeragiel. Her physical appearance was the same as always, but there was a stark difference from the usual Zeragiel with the one standing in front of him now.

The queen was wearing nothing but a transparent nightgown. She was not even using underwear under the gown, leaving her entire voluptuous and alluring body on display and being completely exposed to Kakeru's hungry eyes, which were eagerly devouring the sexy sight given to them by the queen.

''I apologize for making you wait so long, Hellshaft-sama. "Zeragiel smiled, walking towards the still gaping Kakeru, although, she was unable to notice this because of the armor that covered the boy's entire body from head to toe. He couldn't help but focus on the two huge and brown objects that rose and fell each time the queen of the dark elves walked.

''A-ah, yes, don't worry, it didn't take that long for you to arrive here'' he said, still distracted by the queen's naked breasts that were being covered by the thin trasparent layer of clothing.

''She didn't notice me hornily observing her, did she? I mean, with the armor on there's have no way of knowing where I'm looking at so I must be safe." He was convincing himself of that. Zeragiel then laughed, causing Kakeru to focus on the woman's gorgeous face.

''What's it? What's so funny?"

"Ah, nothing much." She waved her hand as if not giving much importnce to it. "I just thought how strangely adorable you can be when trying to disguise that you're intensely staring at my breasts."

"...!" The words that came out of the dark elf's soft lips made him almost choke on his own saliva, this reaction, of course, did not go unnoticed by Zeragiel.

''We women are sensitive to lustful eyes, I guess it could even be considered some sort of sixth sense from the point of view of you men. "She laughed in a good mood ''But don't worry, you can look all you want, knowing that my body makes primitive and raw desire burn deep inside of you, the king of hell, makes me shiver with excitement.'' She spoke seductively, sitting next to Kakeru on the soft bed as she touched the metallic breastplate of the armor and pressed her big breasts against one of the boy's arms.

Due to being able to feel the softness and warmth of Zeragiel's erotic body even with the demon king's black armor, Kakeru began to feel like a certain friend of his inseparable from birth began to unconsciously enter it's hardened state.

''I-I thought that your way of sealing our pact would be just the same activities we engage ourselves in whenever we're this room every time I come to this country, but I see that I was mistaken. "He commented, recovering his posture a little and trying to act like his usual demon king persona.

''For a event as glorious as the unification of Rowalrinna to the kingdom of Hellandia, which in the future will be the empire of the being who will be great enough to dominate the entire world, we need to seal the agreement in a more radical and...pleasant way. "

Staring at Kakeru, Queen Zeragiel licked her glossy lips in a sensual way, her ruby-colored eyes shining predatorily.

''Really, great achievements must be sealed with glamorous celebrations, but unfortunately, queen of the dark elves, a being like me that transcends the living things of this world, surpassing the dimensional walls and causing fear and envy even in God can only accomplish simpler activities like kissing and light caresses because of my inability to faithfully recreate a form similar to that of the creatures of this world. "Kakeru invented a momentary excuse to make Zeragiel give up on the idea of engaging in sexual activities with him. It's not like he didn't want that to happen, on the contrary, if that chance had appeared in another moment, preferably a more tranquil one, he would have accepted what was being offered now without any hesitation and surely he would have released his desires on this wonderfully beautiful woman, but due to the gravity of the current situation, he had a lot to plan, besides emotionally preparing himself for the time to face the Orzelia Order.

Kakeru hoped that his lie would be accepted by the queen since, at least for him, he sounded convincing enough, but to his misfortune, that was not the way things went.

''You don't have to try to play hard to get, Hellshaft-sama. That fallen angel you have as a subordinate has already mentioned to all my maids that you are capable of assuming a human form and how skilled you can be in the bedroom arts.''

''Forneus! How can you be such a bad girl?! You stupid fallen angeeeeeeeel!" Kakeru screamed in his mind when he discovered how Forneus could gossip so easily.

"But I have to admit, you can act cute in the most unexpected moments, it's like you're nervous to feel the contact with my body, such an innocent reaction really ignites the passion inside me~." She whispered, quickly moving her face closer to Kakeru's. When the front of the armor inadvertently opened, he felt the familiar sensation of the queen's warm lips on hers.

''It seems that there is no way to avoid this situation, well, better satisfy her fast, that way I can return to Infermia as soon as possible and prepare myself properly for the battle that will take place in Arzheim.'' He thought with an internal sigh.

Snaking one of his hands to the back of Zeragiel's head, the teenager grabbed her long silky silver hair and pulled it gently, drawing her even closer to his body and closing his eyes before invading the elf's mouth with his tongue. The tall woman made a muffled sound of surprise when she felt Kakeru's tongue come in contact with hers before she too closed her eyes and reciprocrated the kiss. When the kiss intensified as their tongues tangled with each other in a wet dance, she let out a noise similar to a purr of joy.

As the minutes went by, the need for oxygen began to become present, causing Kakeru and Zeragiel to slowly separate their connected lips.

''Hmm, how nice to see that despite your innocent reactions on certain occasions, you are the owner of an overwhelming passion, Hellshaft-sama. "Zeragiel spoke happily.

'It is an honor to receive such praise from a woman as powerful and seductive as you, Zeragiel. I believe it is time to deepen our ties, and for that, we will let our bodies dictate everything.'' Thus declaring, Kakeru removed the demon king's armor, leaving only the helmet, which covered his face just above his nose. Observing the boy's actions, Zeragiel smiled, but soon pouted when she saw that the helmet was still being used by the king of hell.

''Hellshaft-sama, there is no need to hide your face from me. My country belongs to you, my body, heart and soul are also yours to fo as you wish. We are alone, nobody but me will be able to see your how you look with your human form, I even sent my maids away not only from the corridor, but from this area of the castle as well so please, show it to me, I want to make love with you while looking at your face, I want to see the sparkle of desire for me shine in your eyes instead of simply looking at your helmet. "She proclaimed, strangely serious. Kakeru couldn't help but be surprised by the dark elf's firm words.

"She is implying if I reveal my identity to her, it will remain in this room, just between the two of us and that no one else will know about what my physical appearance is like, but is it a good idea to do so? To show my true self to this woman in front of me?" He couldn't help but ponder over that and theorize about the consequences that would result if his identity was leaked to someone dangerous, but one look at Zeragiel's face was enough to make him realize that she really would not allow anyone but her to gain such knowledge.

A minute of silence passed between them and Zeragiel, despite showing no external change, was clearly anxious for the boy's response.

And that answer arrived in the form of actions, not words.

Slowly, Kakeru's hands went up to the helmet. He felt as if time was moving in slow motion as his hands, which gripped the helmet, came back down, finally allowing his face to be completely naked for the silver-haired woman.

He initially thought that the queen would have a reaction similar to that of the elves when he and 2A Guild where taken to Weisskrone castle when they went to meet the queen of the elves, Ulriel. But instead of showing disinterest in his appearance or even considering him ugly, her reaction was radically different.

''Oh dear!'' Zeragiel exclaimed as she studied the boy's naked face and body, recording every physical aspect of him in her memory ''Who would've thought that the future ruler of this world would be such a cute and...appetizing boy. " The predatory glow that Kakeru had seen before in her eyes instantly came back. Was it just his impression, or did it feel like the lust dancing in the queen's ruby orbs had increased significantly?

"I'm so happy." She declared, walking towards Kakeru while rocking her hips in a sexy way with every step taken. When she stopped in front of him, the boy was able to notice how ridiculous the difference in height between him and Zeragiel was when he did not have the two meters and thirty centimeters of height provided by Hellshaft's armor.

Before he could even utter a single word, the silver-haired elf spoke.

''I just know that our night will really be...amazing~" And with those words, she pushed him onto the bed. Climbing on top of the naked and petrified boy, she once again pushed her face towards his, stealing his lips in another kiss that would leave both breathless.

I mentioned that I would write a Forneus story, but since I love Zeragiel as much as her and almost as much as Aikawa, I decided to go for the beautiful queen of the dark elves this time. Anyways, I guess I blue balled everyone in the end...Worry not! This will have another chapter, the next one being where all the ''action'' takes place so see you all next time!
