Tachibana Hinata and Jinguuji Tsukasa have been best friends since childhood. Now, at 32 years old, they're both average businessmen. One night after a mixer, an entity calling itself a goddess sends them to another world. When Jinguuji opens his eyes, he sees Tachibana, who's been transformed into a beautiful, blue-eyed, blonde girl. Now that the two are of different genders from each other, they're each bewildered by the other's charms. They steel their determination to defeat the Demon Lord in order to return to who they were with their relationship still intact.
She cast the worst, nastiest curse 
she could as a goddess of love!
!بل ألقت أسوأ وأفظع لعنة ممكنة كإلاهة للحبّ
sie hat uns auch noch mit dem schlimmsten
Fluch einer Liebesgöttin belegt!
nos lanzó la peor maldición
que pudo como diosa del amor.
nos ha cascado su peor maldición
como diosa del amor.
Déesse de l’amour, mon cul,
c’est la pire malédiction !
ha dovuto lanciarci la maledizione
più cattiva e terribile come dea dell'amore!
também lançou a pior e mais desagradável
maldição de uma deusa do amor!
так ещё и худшее из возможных
проклятий наложила!
