Not long, actually.

As he was pondering the question, the egg of the Glacial Greatwyrm began rumbling a tiny rumble, as it began cracking. All the while, the egg of the Glacial Phoenix began freezing over, an icy mist emanating from it.

After a moment, a Draconic figure burst from the first egg, as it instantly grew to seven feet long from the tip of his nose to his tail, releasing a mighty, while still cute, roar, before the other egg, frozen solid as it was, turned to brittle shards, as it collapsed harmlessly atop the regal form of the Phoenix, before it flew to perch atop his shoulder.

This brought a happy grin to Frostin’s face, as he watched the absurdly large Greatwyrm hatchling begin crawling around the grand chamber, before slithering up to him, and resting his Draconic maw atop his lap, expecting headpats, looking into his eyes with a bluish-red tinge staring back, contrasting with the Greatwyrm’s platinum blue scales.

“I think I’ll name you… Snowscale Winterfang, The Harbinger Of Frost.” As he was smiling to himself, the happy Greatwyrm rolling around in joy in his eyes, he felt a sudden pecking at his head, as a certain Phoenix was apparently jealous. “Ok ok, you… I’ll name you… Glacielle Winterfang, The Quill Of Frost. Happy?” Glacielle was, as she nuzzled into his side, bringing a cool sensation to him, it was quite pleasing.

“Well… What do Demon Kings do all day?” While Musume was confused as well, the demoness from before spoke.

“Hello sir, Demon King. While I have no experience with Demon Kings, a Demon Lord could choose to descend on one of the many random mortal worlds upon accepting an offering. I don’t see why it wouldn’t be the same. Uhh, my liege…” She added as she finished speaking.

“Ok… Show me where I do that.” Frost chose to act on this immediately, as a grin came to his face, he started following the demoness.

After a minute or so of walking, he reached an odd altar, where the demoness began preparing a ceremony. While she was preparing, she introduced herself, “Sir Demon King, my name is Renesme D’Alarin, an Everfrost Succubus.”

“Ok…” Frost responded passively, though he felt the impact of her words. She’d given him her TRUE name, at least some of it, which was a lot more than most Demons would choose to do. “While I am gone, take care of the people in my care, and I shall reward you greatly. After my boredom is sated, that is.” As he grinned, she accepted gratefully, as she continued her preparations.

After a minute, a blood red portal opened, as an innocent voice was heard crying, “Puh, puh… Please don’t take my daddy Demons please, please save him for me… Someone… Please.”

As he heard the childish voice coming through, a spot in his heart which had always been present started aching, but while he was stuck in his feelings, Renesme apologized, before starting to find another portal, but Frost stopped her.

“No, dear Renesme, don’t lose this connection. That’d be your head.” He said roughly, staring a cold glare into her eyes, as her heart dropped, before restabilizing the portal access. “Well… I’ve heard her pleas, I’d have to be a villain to ignore a child in distress. And whoever was so cold as to leave her without a father, they best pray to never meet me, though that might be my only goal there. I… I couldn’t stop it before. But now…”

“Ok, the portal is ready, Sir Demon King. You can go through now. I… I wish you luck.”

“Thank you Renesme, Take care, and you as well Musume, keep an eye on the place.” He spoke affectionately to Musume, shocking Renesme, and bringing Musume to a blushing fit, as Frost stepped through the portal.

As he disappeared, a confused Renesme asked Musume, “ What’ya think he’s gonna do over there? Is he gonna eat the girl?” She asked deviously, but Musume quickly denied it.

“No, you’re wrong, he wouldn’t do that. He’s not like the last one…”

As she trailed off, Renesme interrupted her, “Yeah, and how was the other guy during the first FIVE days?”

After that harsh but true statement, Musume couldn’t rebuke her, but she felt it wasn’t true, she felt his care for her HAD been genuine, there was no faking that, at least, that’s what she felt in her heart to be true.

…

As he entered the portal, Frostin began experiencing something similar to what he’d gone through at the start, only going up instead, as he was flying towards some human world. He wondered which one it’d be?

But he didn’t have to wonder for long, as he appeared in the grimy basement of packed dirt, a miniscule girl sobbing over the fallen body of her father.

“... Hello, little girl. What’s wrong?” He stupidly asked.
