Synopsis: Saikyou Ansatsusha no Ossan, Sekai wo Sukuttara Maougoroshi no Akuyaku Reijou wo Oshitsukerarete Henkyou Ryoushu ni Narimashita

**Greatest Assassin Senou, a hero who fought brilliantly in the war against the Demon King's army, was granted his reward: a peerless beauty and a territory. However, the reality was the villainess Alicia Scarlet, slayer of the Demon King, and the scorched ruins of the demon castle she had burned down.** For the royal family, who believed peace had arrived, these two wielders of inconvenient power were troublesome and were summarily exiled to a remote frontier. Thus, they were both "disposed of." Though cast aside, the two began working to develop the desolate demon castle ruins. Gradually, humans and demons who admired Senō started to gather there...Meanwhile, the kingdom, which had discarded Alicia and Senō as unnecessary, dispatched an army as planned to eliminate them. But to these two who were far too powerful, neither the kingdom nor the remnants of the Demon King's army posed a real threat...? **A tale of an overpowered comeback by discarded heroes!** *Source: MangaUP, translated*
