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.
But why is it only you who 
was given your ideal form?
لكن لمَ أنت هو الوحيد الذي منحت هيئتك المثالية؟
Aber wenn du zu deiner
Traumfrau geworden bist,
Pero ¿por qué solo te dio a ti
tu apariencia ideal?
Pero ¿por qué solo te dio a ti
tu apariencia ideal?
Pourquoi tu t’es transformé
en ton idéal,
Ma perché solo tu
hai ottenuto il tuo aspetto ideale?
Mas por que só você recebeu
a forma que considera ideal?
Не пойму только,
почему один ты преобразился.
