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.
You think that's how you killed
 that with one punch?
أتعتقد أنّ تدريب الوزن يجعلك تقتل 
ذاك الشيء بلكمة واحدة؟
Und mit Training
massakrierst du ’nen Bären?!
¿Y por eso das golpes mortales?
¿Y por eso das golpes mortales?
T’as dégommé un ours
d’un seul coup !
Secondo te basta quello per uccidere
un coso simile con un pugno?
Acha que musculação vai fazer você
matar um urso com um só golpe?!
Ты голыми руками медведя завалил!
