I, Nakao Ryuu, had a strange dream. It once happened while sleeping on my desk. While looking through a stack of documents, i suddenly felt sleepy. Then suddenly, a girl with a pointy ears and a slight transparent wings (she looks like a fairy) woke me up.

"Mister, mister!" The girl who looked like a 12 years old with a size of three inches tried to shook me up.

When i got up, that girl said: "Mister! Please help us!"
