Known by the alias "Kuro," William Macbeth hails from a prestigious lineage of sorcerers and was born with an exceptionally rare level of psychokinetic power. Childhood trauma, however, drove him to voluntarily suppress and seal away his own abilities. When catastrophe struck in the form of the Great Collapse, William made the selfless decision to offer his own body as a living vessel for the enigmatic dark entity called the King of Despair—all to save his twin sister Shiro from death. His shared experience of hardship and inner conflict forged an unexpected but genuine bond between him and Leo.
