Takuto and Meroko, inadvertently tip Mitsuki off that she has only one year left to live. Mitsuki's dreams seem impossible to achieve, until one day she is visited by two shinigami, Takuto and Meroko, whom only she could see.
At the same time, her grandmother hates music and is completely opposed to Mitsuki's wish to audition. Her tumor is curable only through a surgery that could damage her vocal cords.
