Uchida is a high school student genius who created a device that is
supposed to make people have good dreams but he always had bad dreams
when he tried it on himself.
One day, he caught the school doctor sleeping at the clinic and decided
to try the device on her. It turned out that it works surprisingly well
on her and that she wanted to buy the device from him. He then tries it
on his classmates and it became quite popular with the rest of the class
as people start lining up to borrow it. Meanwhile, there is growing
concern that users of the device are starting to have difficulties
differentiating dreams from reality...
