Orhun Dura is an adventurer who is expelled from the Hero's adventuring party by Oliver, his childhood friend and leader of the group. Oliver mocks Orhun for lacking skill and being a "jack-of-all-trades, master of none," even though Orhun switched from being a Swordsman to an Enchanter for the sake of supporting the party. Dejected and directionless, Orhun leaves to prove himself as a solo adventurer, striving to become the strongest "jack-of-all-trades" in order to protect his friends and stand against injustice.

Fortunately for Dias, a horned girl by the name of Alna is about to show him there’s more to the plains than meets the eye!
