With the Light... Vol. 4

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?
