Orun Dura, once a skilled swordsman, adapted to the role of enchanter to fill a crucial gap in the Hero Party led by his childhood friend Oliver. Despite his loyalty and the original magic he developed to support his companions, he is abruptly dismissed for being a jack-of-all-trades and a master of none, his former comrades having already chosen a successor. Betrayed and in despair, Orun is cast out of the party he helped build.

Determined to start over, Orun returns to adventuring as a solo swordsman, the role he originally excelled in. The experience, knowledge, and countless original spells he developed as an enchanter have not gone to waste, forging him into a warrior with an unconventional and powerful skill set. His reputation soon attracts the attention of the formidable guild known as the Night Sky Silver Rabbits. Selma Clodel, the guild member publicly renowned as the Strongest Enchanter, is genuinely surprised by Orun’s expulsion and immediately attempts to recruit him. He initially joins as a temporary instructor for a party of newbie adventurers, including Selma’s younger half-sister Sophia, the reckless dodge-tank Caroline Inglaud, and the haughty but earnest enchanter Logan Hayward.

As Orun begins to forge new connections and prove his true strength, he must also confront the shadows of his past. The machinations of Filly Carpenter, the one who orchestrated his expulsion, are part of a larger conspiracy involving the criminal organization Cyclamen Cult. This cult is responsible for past tragedies, including the slaughter of Orun’s village and the abduction of Caroline for cruel experiments. Furthermore, Orun’s own hidden history begins to surface. He possesses sealed powers and lost memories from his childhood, including a forgotten bond with a girl named Shion. As he subconsciously breaks the seals on his godlike abilities through sheer force of will, the story follows his journey from a discarded support mage to an unparalleled warrior, protecting his new family in the Night Sky Silver Rabbits and confronting the cult and his former party members who once betrayed him.
