Operating under the alias Lady Inimicus, Shade serves as a primary antagonist manipulating events from behind the scenes. Her central influence fuels major political conflicts within the Kingdom of Eristein, where she orchestrates Duke Dortesheim's rebellion against King Gilmar to destabilize the realm.

Shade employs dark magic and necromancy, notably casting a berserker spell during the Battle of Wennifix to drive soldiers into a frenzied state of violence. She leverages existing tensions between traditionalists and reformers within the kingdom to incite civil war.

Her schemes extend to exploiting summoned individuals from other worlds; evidence suggests she played a role in transporting Taichi Nishimura to Altianutz, intending to harness his extraordinary magical capabilities for undisclosed objectives tied to controlling the world's fate. Shade intervenes directly, commanding powerful entities like the dragon responsible for Anastasia's death during the Battle of Azpire. This act eliminated a potential obstacle while demonstrating her capacity for calculated cruelty.
