William Glasdale, known as the "Ulysses Hunter," is a methodical antagonist who hunts those enhanced by the Philosopher’s Stone. He wields a massive, custom-engineered crossbow armed with the Lance of Antioch—an ancient relic historically tied to the death of Jesus, now forged into a Philosopher’s Stone. This weapon neutralizes the regenerative powers of Ulysses, enabling him to deliver irreparable, fatal injuries. His lethal precision poses a dire threat to Jeanne and Montmorency.

During confrontations, Glasdale allies with Ulysses Noire, Philip’s alternate persona, to trap Jeanne. His tactics focus on pinning her in place long enough to launch the Lance through both her and Montmorency in a single strike, targeting their hearts to ensure mutual annihilation. The assault leaves Jeanne seemingly dead and Montmorency powerless to counter. Glasdale’s ruthlessly efficient strategies combine historical weaponry and alchemical manipulation to systematically eradicate Ulysses targets.
