Fantasy Bishoujo Juniku Ojisan to

Tsukasa Jinguuji and Hinata Tachibana have been best friends since their student days. Jinguuji is a good-looking charmer with an abundance of luck with women, whereas Tachibana has never been so lucky. Despite their differences, the two remain close even in their thirties.

One night, on their way home from a mixer, Tachibana wishes out loud that he could become a beautiful girl with irresistible charm. As if by a miracle, a goddess appears before them and grants Tachibana's wish, transporting them to another world where they must conquer the Demon Lord in order to return home.

In his new female form, Tachibana is so charming that even Jinguuji is captivated. Tachibana also understands why Jinguuji is so popular. Before they can fall in love, they have to complete their mission, or they will remain prisoners to their infatuations forever.
