Sybil, the eldest son of the combat-focused Lockwood family, was granted the skill “Divine Interpretation Metis,” which answers any question with a simple “yes” or “no.” Dismissed as useless in battle, he is cast out by his father. His younger brother, gifted with the power of a “Sword Saint,” attempts to kill him, but Sybil escapes using his “Divine Understanding” and eventually reaches the Rodel Empire. There, he encounters the noble and striking knight Eve and the charming, cunning merchant Neon. With “Divine Insight” at his side, Sybil ventures into trade, monster hunting, and battlefields, overcoming danger after danger. Thus begins a fantasy tale of defying destiny with the ultimate optimal solution!
