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.
Say, doesn't it seem like we've been 
cursed to fall in love with each other?
ألا يبدو من الغريب أنّه أصابتنا لعنة الوقوع
 في حبّ بعضنا البعض؟
Hey, der Fluch zwingt uns, dass wir
uns ineinander verknallen, oder?
Oye, ¿no te parece que nos maldijo
para gustarnos mutuamente?
Oye, ¿la maldición no sería
para gustarnos mutuamente?
Tu crois pas que la malédiction,
c’est qu’on tombe amoureux ?
Senti, non sembra che ci abbiano lanciato
una maledizione per farci innamorare l'uno dell'altro?
Ei, não parece que fomos amaldiçoados
a nos apaixonarmos um pelo outro?
Слышь, а проклятие это, часом,
не вынуждает нас любить друг друга?
