A heroic and mighty adventurer dreams of…opening a pharmacy?

Red was once a part of the Hero’s party, a group destined to save the world by fighting the Raging Demon Lord. But after being betrayed by his comrade, Red hopes to start anew by opening a small apothecary in a sleepy town on the frontier. While keeping his past life a secret is the goal, it won’t be easy…especially when a beautiful adventurer from his past asks to move in.
