Akio Honjou is a high school student with a special gift for music. He can perfectly recall any piece of music that he has heard only once. One day, as he tries to reproduce a particularly soothing piano melody, he unexpectedly meets Juri Makina—the girl whose cell phone had spontaneously played the tune earlier in class. If art is the only way to truly know what landscapes populate others' inner worlds, then can this particular tune pave the way for Akio to begin to understand the more intellectual and emotional aspects of his captivating classmate, Juri?

The heroine is a normal girl, until one day she is invited to another world and becomes the princess of the dream world, where people use dreams as the energy to live. One day, the dream world is being attacked by something called "yumekui" ("dream eater"), and many princes are being attacked by it. The heroine must wake them up to save the dream world, as the princes are unable to wake up due to having their dreams stolen.

Set in a world where the concept of music ceases to exist. The story begins when a boy encounters Myuu, a mysterious girl who possesses an audio input jack in her body. The two intermingle with the history of rock music and embark on an unforgettable journey. (Source: MAL News)
