Error Code: Humanity

Trapped inside a virtual death game where a single mistake means permanent death, two unlikely players fight not only for survival but for answers.

Rin, a quiet and calculating lone swordsman known as the Crimson Willow, has no intention of joining guilds or making friends. Aya, a cunning alchemist who thrives in the shadows, trusts no one but the poisons she brews and the silence between attacks. Both thought they could climb the floors alone... until they realized this game hides more than code.

When whispers of a corrupted AI and an ancient force buried beneath Aincrad begin to surface, Rin and Aya find themselves entangled in a mystery that threatens not just the players, but the fabric of reality itself. The deeper they go, the more they question:
Is this still just a game or a prison designed to erase humanity?

For fans of SAO who crave darker paths, complex bonds, and battles where steel cuts deeper than skin this is your next obsession.
