The Strongest Middle-Aged Assassin Saved the World, but Was Saddled with the Villainess Who Killed the Demon King and Became a Frontier Lord

Summary

English Title : Saikyou Ansatsusha no Ossan, Sekai o Sukuttara Maougoroshi no Akuyaku Reijou o Oshitsukerarete Henkyou Ryoushu ni Narimashita Summary: Senou, the strongest assassin and hero who distinguished himself in the war against the Demon Lord’s army, is given a reward: a peerless beauty and territory. However, the reality is that it’s Alicia Scarlet, the villainess who killed the Demon Lord, and the ruins of the Demon Lord’s castle that she burned down. For the royal family who thought peace had arrived, these two with excessive power are troublesome existences, so they essentially isolate them together in a remote area as a way to dispose of them. Though cast aside, the two begin working to develop the barren Demon Lord castle ruins. Humans and demons who admire Senou gradually gather there… Meanwhile, the kingdom that expelled Senou and Alicia as unnecessary sends an army to eliminate them as planned. But for the two who are far too strong, neither the kingdom nor the remnants of the Demon Lord’s army pose any threat…? A reversal tale of the discarded heroes dominating!
