Yuusha-chan ga Kaeranai!

The Hero, Leeds came to the capital in preparation for the upcoming battle against the Demon Lord, but her adjutant, Aschera was denied entry due to his low contributions. Two years have passed since then, and Aschera is now the lord of a frontier town founded by himself and is living in bliss with the townsfolk. Amidst this lifestyle, a sudden guest visits— “Wassup! Long time no see, Schera!” His past comrade, Hero Leeds had come! It appeared that she missed her old friend and came to visit. Aschera thought she would soon leave the town, but she’s readily getting closer to the townsfolk!? Besides tending to the fields together, she also helps out with hunting as Aschera watches over peacefully. They share meals together, go out together and even sleep on the same bed! Source: Overlap
