Beyond the shadow of demon incursions and battlefield rages, near Zoltan"s frontier, a D‑Rank explorer named Red leads an ordinary life. By steadfast effort and diligent toil, he finally realizes his aspiration to open a modest apothecary and enjoy a tranquil rural existence. Suddenly, Red welcomes an in‑house companion and aide named Rit—the princess of the Loggervia duchy and a fellow adventurer—who relinquishes everything to join him.
Despite being sincere, benevolent, and universally admired, Red keeps a secret known only to Rit: his true name is Gideon, the brother of Ruti Ragnason, the "Hero," and a former squadmate. The sage Ares Drowa expelled Red from their group after the clash with the Demon Lord, deeming him feeble and unimportant. Even though Red has abandoned the Hero"s party by starting anew with Rit, his past still clings to him. Yet the echo of past vows lingers beneath his serene days quietly.
