The second condition from the demoness was a requirement of loyalty. Dion wasn't allowed to serve any other demon other than Lythia whether they be less or more powerful than she was. Dion didn't exactly mind this. He didn't have a plan of consorting with other demons anyway. The third clause that she put up was also related to loyalty. Dion wasn't in any way allowed to sabotage, betray, or in any way work against her, whether directly or by proxy. He couldn't share her plans or secrets with anyone unless whatever he shared helped in the overall success of her plans. The penalty that she put for breaking either condition two or three was that Dion would lose the protection of his third condition. Dion had been completely objected to this and had tried to remove this part. This time, however, Lythia had been prepared and after a minute-long battle between the two of them, they had settled on Dion losing the protection of his third condition only for a day every time he broke either condition.
Dion didn't know whether Lythia had planned to add other conditions or not. But suddenly, the runes flashed brightly and then began to fade away. But even as they faded away, Dion felt like someone was marking him. The time for editing the contract was up. It was now set in stone. Even without having to ask, Dion knew that they were both now bound by the soul contract. Dion couldn't help but smile at the symmetry. In the end, Both Dion and Lythia had only gotten to put up three conditions on the contract. He didn't know of Lythia had put up what mattered to her the most. He, on the other hand, was quite satisfied with what he'd put up.
Lythia couldn't help the annoyance she felt as she opened her eyes. Even worse than the fact that she'd been unable to remove the conditions that the boy had put up, the boy had forced her to change the conditions that she had put up. She had tried her best to keep the condition as it was, but the contract had kept on rejecting it because it recognized Dion as the stronger party of the two. If Lythia hadn't put everything she had into forcing through a suspension of his third condition for a day if he broke her conditions, then she wouldn't have gotten even that much.
Lythia was starting to worry that she had lost a lot more than just power over the millennia. Had her soul become weak enough to be overpowered by a child? But she was still a demon lord, so that couldn't have been it. And yet, according to the soul contract, he was the stronger of the two of them. But how?
Almost as if in response to her question, the answer came in the next second when Dion opened his eyes. Lythia had to school her face to keep her expression neutral when the boy's eyelids opened up to reveal bright purple irises looking up at her. All of a sudden, it all made sense. The reason he'd been able to sense the contract wasn't because of some secret occult training he'd gotten. It wasn't even because of some outstanding thing about the boy. Instead, it was because he had a demon lord's soul energy already flowing through him. With a demon lord's soul energy in him, his innate soul sensitivity must have shot through the roof. With her energy inside him, not sensing the soul contract would have been the mystery.
It also explained why the soul contract had considered the boy stronger than her. When she had appeared in this realm, the boy had barely had ten percent of his total soul energy remaining. She hadn't been willing to take any chances with him, so she had pumped him full of her soul energy till he was back at one hundred percent. The boy before him now had the soul energy of a demon lord circulating through him and a bit of his own. To a soul contract, what mattered more was the quality of soul energy, not the amount one had. As such, by saving the boy's life she had unwittingly given him the upper hand in the soul contract negotiations. With her soul energy already circulating within him, it was the little bit of his soul energy that he'd remained with, that gave him an edge over hers.
The reason why demons didn't share their soul energy with humans, was because it would take away from their powers, leaving them weaker. Lythia, however, had already been significantly weakened by the time she appeared in the mortal realm, losing a bit more of her power didn't make all that much difference. Not to mention the fact that being slightly weaker was still incomparably better compared to being made into a slave for the princes of hell. As such, Lythia wouldn't have acted any differently even if she had to do it all again. However, due to filling him with her power, she hadn't gotten as much out of the soul contract as she would have wanted to. 'Annoying, but considering what would have happened if I didn't save him, acceptable,' Lythia found herself thinking.
Back when she had been a powerful demon lord, she'd heard of a few demons sharing their soul energy with humans. If memory serves right, it usually took a few weeks to a few months for any changes to show on the human. But then, if she had to put it in proportion, those demons usually gave less than a percent of the human's total soul energy. And even then, it was a chance that was only given to a demon's most loyal followers. The most she had ever heard given was five percent. She, on the other hand, had almost completely replaced the boy's soul energy after just meeting him, even before they had established any contract between them. Something that no demon would ever do.
It had only been an hour since Lythia had appeared in this realm and yet the soul energy she had pumped into the boy had already begun to affect him. Lythia wasn't all too surprised, however. After all, unlike the demons she'd heard of in the past, she hadn't just given the boy a small amount of soul energy. Barely ten percent of the soul energy he now had was his own. The rest was from her. It was a wonder that there hadn't been more drastic changes to the boy as a result of what she'd done. Even his eyes which seemed to have turned purple like hers as a result of interacting with the soul contract were slowly reverting to their natural jade color.
It also, now occurred to her that, had the boy refused to form a contract with her, he still would have walked away with what he wanted. He would have been far stronger than he'd been before he met her. And more importantly, if he nurtured his power the right way, he would have grown to be more powerful than most humans on the planet. In short, the only one who had truly benefitted from the contract between them was her. This thought removed the sting of having lost the soul contract negotiations and caused a smile to cross her face. In the end, it was she that had won.
"You know," Dion spoke up. "I know you are a demon and all, but if you want this arrangement between us to go smoothly, don't try underhanded tricks with me," Dion spoke in an icy tone.
"You said it yourself," Lythia spoke up with a smile, completely unfazed by his demeanor. "I'm a demon, not charity," She replied.
Dion regarded her for a while before stating. "We are going to be lifelong partners. If you want this relationship to be full of lies and underhanded tricks from both of us, then I'm game," He said with a shrug. "But if you want all of our focus to be on achieving our goals instead of wondering whether we can trust each other or not, then you can't lie to me. Ever!" he stated with a note of finality.
In any other situation, Lythia would have slapped him into the wall before making sure he understood in the most painful way possible, why it was a bad idea to threaten her. With the contract binding them, however, all she could do was remind herself that in a hundred years, he'd in all likelihood be dead. While for humans, this was a long period of time, for her it was but a blink. Before she knew it, he would be manure in the ground. Besides, he was going to play an important role in her plans, she couldn't afford to antagonize him. She had already put it in the contract that he couldn't do anything to harm her plans. Being a demon, however, she knew better than most that there was almost an infinite number of ways that one could find loopholes in soul contracts. As such, despite her intense displeasure, she simply smiled and said. "Okay. We'll try doing it your way," she replied. "Now strip!" she commanded...
