An angel, lost on Earth after failing to return to heaven, reincarnated as a human but retained his celestial powers. As he aged, the power became too much for his mortal body, leaving him lonely despite having siblings. He eventually made a close friend and, knowing his time was short, began distributing his powers through injections of his celestial blood. His friend was the first to receive powers, followed by the angel's sister and many others.

To help these new power-bearers, the angel created a separate universe called the Chūkan (The in-between) above Earth with a school in which he called  “The Helios Empire academy” where they could learn to harness their celestial aura. The angel ruled the school until his friend, seeking control, demanded a share. When the angel refused, the friend took over during his absence, ruling with an iron fist and sparking a deadly war.

The angel returned to find his friend had married his sister, and they had a daughter. Heartbroken, the angel banished them and their followers to a sealed realm called  Terra Firma.
 Before departing on another journey, he appointed twelve powerful beings to govern his universe and placed his niece and her descendants in charge of the school. Then, the angel disappeared, leaving his legacy behind.

The in-between (Chūkan) existed peacefully, protected by a vast barrier casted by the Angel to repell all external forces.
The students of the Helios Empire Academy were tasked only with suppressing lesser evils within the In-between (Chūkan): vampires, criminals, wicked mages, Dark Elves, stained guardians, and infected shifters.

	Ten thousand years later, thousands of mysterious meteors fell from the far sky—far beyond the barrier—disrupting it for a single hour.

	In that moment, the ancient seal placed by the Angels began to weaken, releasing Demons and Devils as old as Chūkan itself. They spread freely across the five continents of the In-between: Gold Gard, Elve Gard, Wizz Gard, Prin.T Gard, and Knight Gard.

	Now, with the barrier damaged and the continents under siege, it falls to the students of the Helios Empire Academy to protect the In-between from ancient evil

Rain hammered the rooftops of Southern Gold Gard, turning the command center grounds into a sea of mud and puddles. Lightning flashed across the night sky, illuminating the towering structure for a split second before darkness swallowed it once more.


Inside the command center, chaos reigned.


Vampire soldiers sprinted through the halls, weapons drawn as alarm bells echoed from every direction.


"I repeat we're under attack!!! Assassins have intruded the command center and are killing vampires!!!!"


A katana burst through the soldier's chest from behind.


Blood trickled from his mouth as he looked down at the blade protruding through his heart.


The assassin behind him showed no hesitation.


A sharpened wooden oak stake drove forward.
