The eldest son of the Lockwood Viscount family, Sibyl, was given the skill 『Divine Understanding (Metis)』 at the age of fifteen. This skill was a non-combat type that could only determine whether the answer to a question was "yes" or "no". However, the Lockwood Viscount family was a family of brawn who had risen to their position through sheer strength. His father, the head of the family, expelled him, stating that a useless skill was a disgrace. Even though Sibyl had devoted himself to managing the territory as the heir, he was cast aside in favor of his younger brother, who possessed a powerful combat skill. Targeted by his brother, Sibyl fled to the neighboring Rodel Empire. There, he made a living through various means, from business to monster hunting. Using the knowledge gained from "Divine Understanding", he steadily rose to prominence. Meanwhile, the Lockwood territory, deprived of Sibyl's leadership, began to crumble. After gaining fame, Sibyl was scouted by the Rodel Imperial Army. Using his skills, he accumulated victories, and his name became known throughout the nations as the Empire's strongest great general.
