In a serene realm far from demon conflicts, Red, a humble D-Rank adventurer in Zoltan's borderlands, enjoys a tranquil life pursuing his dream of crafting potions. His world shifts when Rit, the princess of Duchy Loggervia and an adventurer, becomes his live-in partner, sharing his hidden identity as Gideon, brother to the famed 'Hero.' Banished by Ares Drowa, the 'Sage,' for perceived weakness post-Demon Lord battle, Red embraces a new beginning with Rit. However, as they strive for peace, Red's past shadows their path, refusing to fade.
