When a humble merchant named Banaza is summoned to the magical kingdom of Klyrode in another world, the citizens hope he will become the hero who can take down the threatening Dark Army. Unfortunately, Banaza does not gain any exceptional powers at level one as hero candidates usually do, and he has no way of returning to his old world. As compensation, he is sent to live in a faraway forest. Upon arriving, Banaza levels up once and suddenly gains limitless powers that he now has no idea what to do with. To avoid drawing attention, Banaza changes his appearance and assumes the name Flio. While away from home, he stumbles across a young demi-human girl named Fenrys, who is seemingly searching for the same forest Flio was sent to. However, she attacks him and reveals her true identity—a lupine demon. Luckily, Filo's unrivaled magic overpowers Fenrys, and she swears undying loyalty to him. However, Flio refuses to hold power over her; the two instead begin pretending to be a married couple and embark on a new life together.

After passing away, a Japanese office worker finds himself reincarnated in another world as Ars, the newborn son of the noble Louvent family. The Summerforth Empire, where the Louvents rule over a small territory of a few thousand people, is a medieval-like land plagued by social inequality and political instability. As Ars grows older and learns more and more about his new environment, he becomes convinced that war will soon erupt. Fortunately, though Ars was not blessed with unrivaled strength or extraordinary magical aptitude, he does possess Appraisal: a seemingly unique skill that allows him to instantly grasp someone's current abilities and latent talents merely by looking at them. In an effort to prepare his domain for the imminent strife, Ars resolves to enlist the most exceptional people he can find, paying no attention to superficial qualities like race or social status.
