15-year-old Ikeuchi Aya was an ordinary girl, the daughter of a family who works at a tofu shop, and a soon-to-be high schooler. However, lately, strange things have been happening to Aya. She has been falling down often and has been walking funny. Her mother, Shioka, takes Aya to see the doctor, and he tells Shioka that Aya has spinocerebellar degeneration - a terrible disease where the brain gradually deteriorates to the point where the victim cannot walk, speak, write, or eat. However it does not affect the mind. How will Aya react when told about her disease? And how will Aya live from now on?
