The world ended in a single day.

Monsters appeared. Cities collapsed. Humanity was given a System.

Most people feared the monsters.

Aria learned to fear the survivors.

After losing the only person she considered family, Aria awakens a shadow-based power that grows stronger with every hunt. While others cling to groups and safe zones, she quickly discovers a terrifying truth:

The deadliest threats are not always the creatures outside.

A charismatic leader who always gets his way.

A smiling woman who can turn entire groups against someone with a few carefully chosen words.

People disappearing without a trace.

Living buildings.

Something moving beneath the city.

As monsters evolve and society crumbles, Aria must decide what she is willing to become to survive.

Because in a world ruled by levels, shadows, and hidden horrors…

Humanity may be the first thing worth sacrificing.
