Ren is a nice guy who moved with his parents to the town of Mioka, where he had once lived as a young child and met his first love. He left a so-so impression in his first day in class, and just as he was about to head home, it began to rain hard just as forecasted. When he arrived at the school’s entrance, his classmate who sat in front of him, Shizuku, was standing there, having forgotten her umbrella. He graciously offered her his own and then quickly ran out into the rain. However, he was immediately struck by lightning as he exited the school.
When he opened his eyes, he was inside the school nurse’s office and Shizuku was taking care of him. When her hand touched his face, he had visions of them having sex together. It appeared that he had gained a mysterious ability to see lewd imaginations with anyone who he comes in physical contact with. Triggered by his new ability, he met the slightly clumsy airhead Aoi, the student council president and daughter of the local shrine Erika, and the energetic but androphobic Yuki. So begins his ecchi adolescence not too soon after changing schools.
