From their school years onward, Tsukasa Jinguuji has enjoyed extraordinary success with women because of his striking appearance; Hinata Tachibana, on the other hand, has struggled to attract anyone, eclipsed by Jinguuji"s magnetism. While Jinguuji never pursues romantic interests, Tachibana is constantly yearning for a partner. Despite these opposite traits, the two remain close friends well into their thirties as office workers.
One evening they return from a party where Jinguuji, as usual, commanded all attention. In a drunken outburst, an exasperated Tachibana accidentally utters a wish to transform into an irresistibly beautiful woman. As if the cosmos heard, a deity materializes before them and drags them into an alternate realm to vanquish the Demon Lord, simultaneously fulfilling Tachibana"s longing.
Now inhabiting a flawless female form, Tachibana becomes so alluring that even Jinguuji is entranced. He also finally grasps the source of his own popularity by seeing how stunning he truly is. Before they can fall for each other, the pair must finish their quest or remain captive to their obsessions forever.
