Red finds purpose in measuring out herbs instead of swinging a sword. The quiet rage of someone too skilled to ever truly retire settles into every scene, a man building something small and real because the world's grand adventure destroyed him. When his past catches up, it doesn't shatter the life he's built, it tests whether a person can stay human after being forged as a weapon.

Red was once a member of the Hero's party, a group destined to defeat Taraxon, the Raging Demon Lord. Then Ares, the party's Sage, decided he was weak and worthless and threw him out. Red chose a different path: a peaceful life on the frontier near Zoltan, where he works as a D-Rank adventurer and finally opens his own small apothecary. He hides a secret. His real name is Gideon, and the Hero is his sister, Ruti Ragnason. Keeping that hidden gets harder when Rit, an adventurer from his past and a princess of the Duchy of Loggervia, gives up everything to move in and help run the shop. Only Rit knows who he really is. The result is a fantasy romance with slice-of-life warmth and some action, in which Red's old life still refuses to let him go.
