Prologue

Undertown, a location on Earth where extraterrestrials thrive and make an honest living. Needless to say, there are good and bad aliens. The good aliens work and play, while the bad aliens commit crime and run away.

In the dark depths of this city, the fiend Psyphon and his crowd of villains gathered for a round of auctions. Psyphon raised his voice as he sat at the auction table, displaying the item he was ready to sell.

"Alright, Momosapien DNA sample starting from 50000 credits! These little guys are practically extinct, so this might be your only chance to get them!"

"Two hundred thousand!"

"Five hundred thousand!"

"Five hundred thousand and one..."

"A million..."

Various voices from many different people were heard from the crowd.

"One million credits... any last takers?" Psyphon echoed.

That was when a strong gust of wind was felt throughout the stage.

"Oh, I have one," the voice of a teenage girl was heard, "Raphael, El Re'em!"

"Raphael, El Na'ash," a weaker, more constant voice spoke up.

What appeared to be twins wearing revealing, bondage-like clothing stepped forward, one wielding a large, conical lance, and the other, holding a chainwhip. At first glance, it was pretty hard to tell them apart.

"Wh- who are you?" Psyphon questioned.

"Let's see who will win this round, Yuzuru," the flatter one suggested, "I know I will be the ultimate victor and the real Yamai."

"Wwwww. Stop kidding yourself, Kaguya. Learn from a real adult," the bustier one who seemed to have fewer facial expressions responded.

They nodded at each other, allowing the carnage to begin. Thyphoons were blown everywhere, and everyone was blown away by the performance.

XXXXXXXXX

"I got 36 opponents! Beat that, lowly being," Kaguya puffed her decent chest in front of her sister as she while her heels were resting on some girl with cat ears attached to her head.

"Same here. 36. A tie," Yuzuru spoke softly as she used her whip to crush a mechanical arm that was headed her way, dismantling it and leaving the fragments on the floor.

"I... I miscalculated," Kaguya was about to speak when Yuzuru interrupted her.

"Nope. I counted yours too. There's one more guy though. Let's break the tie..."

The turned behind to see a still-conscious Psyphon, with test tube in hand. Psyphon crawled backwards, before getting on a hovering truck in an attempt to flee.

"Fool! You cannot escape my dark winds. Vorpal Burst!"

"Your escape will be fruitless..."

Kaguya and Yuzuru proceeded to chase after him on foot throughout Undertown, crashing into stores and destroying merchandise in the process, before finally cornering the scrawny, armoured man in his hulking metal truck. They began to rip the truck open with their weapons, previewing a display of various otherworldly merchandise.

Next, they saw Psyphon being ejected into the air.

"Still a tie huh? At least we got some of these. They look really awesome with my pure awe," Kaguya said as she donned a tiara-like accesory that shot a laserbeam on a restaurant signboard. Next, she picked up a vial from the front seat.

"DNA from an extinct species, they said. Maybe I can clone these to be part of my dark armada!" Kaguya chuckled.

Yuzuru snickered as the two of them grabbed some spoils of war and headed off, leaving the vandalised truck to rot.
