Description: Takashi is your typical guy who loves lewd things, but he’s quite gloomy and unpopular. In a bid to be popular and get to have lots of sex, he performed a ritual to summon a succubus. However, something went wrong during the summoning; an erotic curse inflicted his classmates, Rumi and Shino, and the summoned Nemu could not use her powers. Will he be able to fully enjoy his newfound life of perversion in the month before Nemu has to go back?
