In a distant land far from demons and battles, near Zoltan's border, lives D-Rank adventurer Red. After years of hard work and determination, he fulfilled his dream of establishing an apothecary in the countryside. Suddenly, Red receives an unexpected partner and assistant named Rit, who is the princess of Loggervia and a fellow adventurer herself. Despite being honest, compassionate, and cherished by all, Red harbors a secret known only to him and Rit: his true name is Gideon, the brother of Ruti Ragnason, the "Hero," and a former member of her party. Ares Drowa, the "Sage," expelled Red from their group following their conflict with the Demon Lord due to perceived weakness and insignificance. Although Red has left behind his past as a Hero, it continues to haunt him even in his new life with Rit.
