Wakahiko is a kind satori who likes to help others. One day, he heard a strange rumour that there was a village in the youkai world Tasogare where evil spirits gathered. Worried that humans might have accidentally wandered there, he went to check out the village, but was overcome by the intensity of the evil spirits. A few hours later, he awoke in an unfamiliar room with an unusual sensation.
“M-My body has… become that of a girl…!”
He had wandered into Ayakashi Genrou, a red-light district where men go to have sex with youkai prostitutes. Since he could change his form depending on human desires, he ended up as a woman due to the accumulation of evil spirits there. The owner of the brothel told him that if he could gather enough spirits for a hundred people, then he could return to his normal self. So, he decided to work as a prostitute there.
