The main character, Gintarou, is a salaryman working at a cell phones sale company. Ever since his senior taught him how to play Pachinko, he's been going to the Pachinko parlor to play. One day, he sees a customer who seems to have lost at Pachinko.

“ Uwaaaaaaaaaaaan—!!! Uwaaaaaaaaa—!!!”

The man's roar echoed sadly. I felt as if there were a melody... like a flower yearning for the spring breeze. People passing through simply laughed at the man and took pictures, eventually an employee came from inside the store and taps the man on the shoulder, signalling him to leave. It's surely an unacceptable reality for that man... I can understand how he feels. Because I, too, am a man on the loser's path. That man's present will become my future.

That is how the protagonist is living, before he meets “Reiyo Yuria” at the Pachinko parlor, changing his life completely...
