Another school year might be over for Hikaru Azuma, but his mom has no time to rest. With both a new teacher and new classmates of different ages and varying disabilities ahead in fifth grade, Sachiko starts preparing for the difficulties that come with sudden changes to her autistic son's routine. Despite her best efforts, Sachiko meets with much opposition from the new teacher, and the Azumas have to cope with Hikaru acting out as a result of the stressful changes at school.
Moreover, when the time comes for the family to decide on Hikaru's junior high, the local education administrators seem to think that a school for the disabled is the best fit for Hikaru, partly because of his recent behavior. But Sachiko, who has done her research, knows this to be false. Will she and Masato be able to convince the authorities and specialists that they know what is best for their son?
