With the light

When staffing changes at Masato's company get him transferred to a dead-end job in the middle of nowhere, more suffering and despair seem imminent for the Azuma family. However, Masato approaches the situation with aplomb and comes up with new ways to pave the way for Hikaru and those like him to become "cheerful working adults"...with surprising results. Hikaru himself seems to be getting closer, bit by bit, to achieving this goal as the Azumas decide to foster their son's independence in a variety of ways, including getting to and from school on his own. But when Hikaru encounters an old acquaintance on the way home and leads Sachiko to a horrific discovery, will the Azumas be able to return a favor and help out a friend in need?
