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.
Still, just leaving us like this 
when we don't know anything...
...تركنا هكذا ونحن لا نعلم شيئًا
Aber es war schon echt mies von dieser Göttin,
uns hier auszusetzen,
¿Cómo se le ocurre a esa diosa perversa
abandonarnos sin orientarnos ni un poco?
¿Cómo va esa diosa tan borde y nos
deja tirados sin orientarnos un poco?
Elle est vache, cette déesse,
à nous lâcher au milieu de nulle part !
Certo che però lasciarci qui così
anche se non sappiamo niente...
Ainda assim, apenas nos largaram
assim, se nem conhecemos nada...
А богиня нас бросила,
ничего не объяснив.
