Ema is a lycanthrope of the werewolf tribe within the Forest of Eternal Darkness. She and her twin sister Luna are Artists who harness Chaos energy within their bodies. This grants them voluntary shapeshifting, enabling partial or full transformation into wolf form. The twins previously served Lord Villar Constance but later joined Theo Cornaro's faction. They defend Altirk against Prince Milza's invasion, employing guerrilla tactics in their forest home alongside their tribe and allied witches. Ema engages directly in crucial battles, including the confrontation at Castle Unicorn alongside Siluca Meletes, Aishela, and others. She always fights in concert with Luna, the twins operating as a single unit. Following the conflict and the dawn of the new era, Ema remains connected to the extended group surrounding Theo and Siluca.
