Sensing some hostility from the friends of his eldest daughter, Lucifer said "While I can understand that you resent demonkind for invading your world, know we didn't had a choice in the matter. We knew that some day a passage to our world would open, and we would have to invade the world on the other side, or die trying, before whoever was on the other side exterminated us, be it humans or angels. In fact, we fully expected angels to intervene in both case, they can sense when a breach open between worlds, after all. The very fact no angel was seen during our invasion mean God abandoned this world."
"Also, know that all peoples that got turned into mindless slaves or non-demonic monsters would have inevitably been damned if they died before the breach between our worlds. All peoples that had so much as a shot at going to paradise after death, a chance lost when God forsake humanity, we turn into more of our kin." Pursued the demon king. "I'm willing to disregard your current resentment and offer you a chance to become demons, in the name of your friendship with my precious Deonna. The choice is yours."
While Deonna could sense her father was being honest, Jeff & Mike were a bit more doubtful. After all, wasn't Satan known as the Prince of Lies? Alas, not only wouldn't the demon king get anything from lying, since humanity had already lost, but that title suggested Lucifer's father, God himself, was the king of lies.
Finally, the two looked at the demon princess, who seemed to be scared of their decision, fearing they would reject her new father's proposition. Feeling that asking to stay human wouldn't go well, they nodded to each others and accepted.
Deonna expected one of her parents to take care of her friends transformation, but instead, her father said "You should take care of their transformation. Their new place in the world is up to you!"
The oldest princess let surprise appear on her face for a blink, but rapidly scolded her expression into a serious and determined one. She was hell princess after all! And as such she had duties, even if she wasn't sure which ones. What was important is that her father trusted her to take care of her friends transformation, and she had no intention to prove him wrong.
She approached her two friend and each friend got one of her hands on the side of their face. Deonna gently pushed her magic in her friends body, guiding their change. Lilith and Lucifer logically thought she was going to change both the same way, but it wasn't the case. Following her instincts, Deonna turned Jeff into a tall amazon of a demoness. Strong, sexy and with fire-colored hairs, as did his lips, all that contrasted by a skin immaculately white. Then, she grew a long white tail ending in a blade the same color as her hairs, bat-like wings as white as her skin and her nails became fire-colored claws.
Mike for his part became rather shorter while gaining speed and agility, but didn't loose any of his muscles. His skin became burgundy while his hairs, lips and nails became a dark purple. Then, like Jeff before him, Mike grew a long black tail ending in a dark-purple blade, burgundy bat-like wings, a long burgundy tail ending in a dark purple blade, and his nails became claws. But unlike the geek-turned-demonic-amazon, Mike stayed male.
Once their transformations ended, Deonna's friend bowed to her. "Thanks for making us your bodyguards, Princess. We swear to protect you with our life." they said in unison.
"You can rise." Answered the demonic Princess. "And I made you my personal guards because, as my friends, you have a personal interest in my continued existence. So please, while you now are my guards, don't forget you're my friends first and foremost."
"Don't worry Princess, there's no risk of that." Answered Jeff, lightly touching Deonna's shoulder with her fist. "Say… How do you think I should call myself now?
"Thanks. And why not Jenna?"
"I love it! Thanks Princess!"
