Seiran shisutâ: Morechau insui (2010)

Mao, a hostess at a brothel dressed as a nun, is performing oral sex on the manager, Katsuya, telling him it's an exorcism. Afterwards, Mao is fired. The reason for her dismissal is that she had a physical relationship with the company president, but the president's wife found out! Kicked out of the dormitory, she wanders aimlessly until she encounters a homeless-looking man at a shrine who claims to be "God."
