Uberich: Advent Sinners

Synopsis

In the middle of September, the Horiverti Residence in the suburban hills suddenly bustled with energy.

The owners of the villa, the Hartson sisters, saved a boy and a girl from a dark alley. The boy, Joe, could only remember being attacked by an elusive shadow while Raina, the girl and Joe's ex-girlfriend, simply wanted Joe to disappear.

Suddenly, a strange woman in a long, stifling black dress broke into the house. Without hesitation, she released a wave of unidentifiable energy bullets and everyone immediately descended into a confused chaos. Luckily, a woman who called herself Annie came to the rescue.

Annie urged everyone to sneak into the enja Defense Science Institute to find out what had happened but Joe, still clueless, had lost all interest. However, Annie later found a tracker on Joe's body and started to become suspicious of him. Only then did Joe realize there was no way he could stay out of this mess.

In the basement computer lab of the so-called enja Defense Science Institute building, the group uncovers a horrifying secret...

What do the elusive shadow, the tracker, the mysterious woman, a horrifying tunnel, Raina's late father, the supervision in the dark, an assassin, haunted ruins, a space blockade, a thing under the floor, a Space-based Kinetic Bombardment System, a high-track circular-orbit space station, Creators, Power Words, powers from the External, GS, religious wars, and the organization that only seems to exist in Annie's words have anything to do with Joe? What occurred before everything started? When these seemingly irrelevant pieces come together, what kind of future will it create for the world?

The once-deserted Horiverti Residence is becoming eerily lively.
