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.
Forgetting your best friend's 
face is pretty harsh.
.نسيان وجه صديقك المقرّب هو أمر وقح
Hast du ernsthaft vergessen,
wie dein bester Kumpel aussieht?
¿Cómo no te acuerdas
de tu mejor amigo?
¿Ya no reconoces a tu colega del alma?
T’as oublié le visage
de ton meilleur pote ?
È piuttosto crudele dimenticarsi la faccia
del proprio migliore amico.
Já se esqueceu da cara do seu
melhor amigo? Essa foi dura.
Стыдись, олух,
что лицо лучшего друга забыл!
