Tsukasa Jinguuji has had incredible luck with women due to his good looks since their days as students; Hinata Tachibana has had almost none, overshadowed by Jinguuji's brilliance. Unlike Jinguuji, who has never shown interest in the opposite sex, Tachibana is always looking for a girlfriend. Despite their polar opposites, they remain best friends in their thirties as salarymen. One night, the two are returning home from a mixer at which Jinguuji, as usual, was the center of attention. A frustrated Tachibana inadvertently wishes to become a beautiful girl with irresistible charm during his drunken rambles. As if the heavens were listening, a goddess appears before Jinguuji and Tachibana, transporting them to another world to defeat the Demon Lord while also rescuing them.
