Adventure Universe, an isolated part of Gaeabrande…

A dark portal opened up, allowing Zenos Road, Sentibug, and Eraser Kaiser to walk up to a foreboding, crystalline stone, wrapped in magic-sealing chains.

"My lord, are you sure this is a good idea?" Kaiser asked. "You barely sealed her away the first time, and that was at your full power. If she refuses to listen…"

"Fear not, Kaiser. I know Lucifer Crow better than anyone." Zenos assured his subordinate. "She will take this up. Now then…Sentibug."

"Right." the Ladybug copy nodded, holding out a bottle full of black blood and walking up to the stone. "By this, the blood of a SS-Demon Lord…you are freed." she said, pouring the contents onto the rock and stepping back.

For a moment, all was silent before the stone began to rattle and the chains broke one by one. Then the rock burst apart into dust, an ominous aura filling the area.

"Xenosload…" the source of the aura said in a cold, merciless voice. Said voice belonged to what looked like a winged goddess, with a penetrating gaze, yet beautiful features and milky-white skin. However, said skin was covered in feathers like a bird, and she has talons attached to her delicate legs. The three demons trembled at the sinister aura emanating from her.

"Lucifer Crow. I see being sealed away did nothing to lessen your power." Zenos said, trying not to let his nervousness show.

"And I see…you are just a head." Lucifer said. "Hmph. I always knew you were a weakling."

"This was the result of betrayal, not combat." Zenos said. "But nevermind that. I'm sure you're wondering why I've unsealed you."

"No. I was wondering how fun it would be to squash your head underfoot." Lucifer replied.

"Ah-ah! Hear me out first." Zenos plied his rival. "You see…there's a group of adventurers I've had some problems with. I thought maybe you'd like to have a go at them."

"You sealed me away for centuries, and now you expect me to do your bidding like a common imp?" Lucifer demanded with narrow eyes, dark winds beginning to swirl around her. "I'll admit I admire your boldness, Xenosload. For that…I'll settle for slicing you apart quickly."

"Lucifer, they killed Odio!" Zenos said quickly, betraying some panic.

At that proclamation, the winds stopped, Lucifer Crow now looking interested. "Odio? The fabled Nihilistic Demon Lord? The same Odio who used to be the Demon Lord of Melancholy in the Demon Universe before being banished to ours for attempting a coup?"

"The very same." Zenos nodded. "They are quite powerful. And one of them has a Keyblade."

"A Keyblade…" Lucifer repeated, her talons curling in excitement. "Now that…is interesting. I've never had the privilege of killing a Keyblade wielder before."

"Indeed." Zenos said. "They are quite powerful. More powerful than any being that has ever set foot on Gaeabrande before."

Lucifer then grinned, a sight that caused the three demons to cringe in unease. "Yes…that does sound worthy of my attention. Where are they?"

"Not on this world currently." Zenos said. "However, they belong to an adventurer's guild known as Mythos Hearts. They take jobs regularly, so you should be able to find them, given you look hard enough. They are known as the Fatebreakers."

"The Fatebreakers…" Lucifer committed the name to memory. "Very well. I'll kill these 'Fatebreakers' first…then I shall return. I assume you will submit to me upon my return?"

"But of course, Lucifer." Zenos said. "I patiently await your return."

With that, Lucifer Crow flew into the sky, leaving the three demons alone.

"I'm not so sure about this, Zenos." Sentibug said. "Even if she wins, you won't win Gaeabrande."

"If she wins, then we survive, and serve under a lord who treats her fellow demons with respect." Zenos said. "And, on the off chance she loses, then a powerful rival will be dealt with, and the first part of my plan shall be completed. Either way…this will work."
