The Holy Emperor Was Secretly an Absolutely Insatiable Man

"The night has just begun, Miyako."

Miyako, a Japanese woman who has been transported to another world, is living a peaceful life as a pharmacist under the name "Mia." One day, however, a large man is prostrating himself in front of a brothel he is visiting for a house call. "Just the tip is fine!!" It seems he is on the verge of being banned from the establishment because he is too "sexually potent." Miyako, who is troubled by a troublesome constitution caused by the miasma of the other world, asks him to sleep with her in order to quell her raging desires. At that moment, Mia is summoned to the imperial palace and spots a familiar face in the audience chamber. A pure yet erotic other-world romantic comedy about a saint who cannot control her desires and a sexually potent emperor who relentlessly courts her!
