Bayul is the only surviving son of Duke Randert, a living legend of the empire. Since childhood, he has suffered from hallucinations and auditory delusions, making daily life extremely difficult. Due to his father's strong recommendation, Bayul belatedly enters Carrington Academy.

As he makes friends at the academy and begins to open his heart, he discovers the shocking truth: what he thought were frail hallucinations were actually spirits attempting to communicate with him. Awakened as a rare Spirit User (Elementalist), Bayul embarks on a journey of growth, academy life, and uncovering ancient secrets alongside his elemental companions.
