Takuya just moved to Tokyo to start university, but the big city is a bit overwhelming, so he lives with his cousin, Takashi, and his beautiful wife. His life is quite ordinary, until one evening, while relaxing after dinner, a burst of light fills the room and a beautiful girl appeared right before Takuya's eyes! As she drifted slowly down, he noticed she was asleep. He held out his arms to catch her... and from that moment forth his life has never been the same.
Takuya must help Silk, a beautiful witch from another dimension, to travel back home, and for the spell to work she needs him to collect enough erotic female pheromone energy. To assist him in this task she enchants him with superhuman charism, allowing him to bed any women he desires.​
