Thanks for the chapter!
MC might be S+ in terms of being a hero, but F- in terms of socializing, common sense, and thinking. Part of reason to have a party is to have someone watch your back during a fight, cover each other's weaknesses, and take turns on watch so others can rest and recover. Likely arguments about room assignments were due to nobody wanting to room with Mr. Clueless. His application was basically "I'm a great hire and some of my achievements were beating you all up single handedly." Especially if he's the one who caused all the damage can see in her throne room. Anyone know why he fought Merness in a church? If it was a cultural heritage site should've drawn him off somewhere didn't have to worry about collateral damage. Also, considering how benevolent the Maou's ruling has been, was there any need or reason to beat him other than him being one of the Maou's Heavenly Kings? If Marness hadn't been causing any trouble and had been living quietly or being helpful would explain why townsfolk were so upset over the battle and claiming compensation afterwards although wouldn't be the first time a town was ungrateful and tried to fleece a stranger. Encounter with Lili was a hoot, although how did she lose her memories? Shutina is pitiful having all her magic sealed before can show off. Would be really funny if uses magic later to easily settle something MC couldn't handle without taking a while or too much collateral damage. Although is she really a succubus? Looks more like an elf to me. Succubi are suppose to have revealing and erotic clothing (although that can be different according to tastes,) be inhumanly sensual and curved, bat wings coming out their back, horns, and a tail.
