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.
The steadfast 25 years he 
and I have spent together...
...أنّ السنوات الخمس والعشرين التي قضيناها رفقة بعض
Dann würden unsere 25 Jahre
Freundschaft aus den Fugen geraten!
Nuestros 25 años de amistad…
Nuestros 25 años de amistad…
I venticinque anni che io e lui
abbiamo passato assiduamente insieme...
Os 25 anos que ele e eu passamos juntos...
Тазом накроется!
Наша двадцатипятилетняя дружба!
