Once you come prepared from reading the question arcs, Kai assaults you with a tremendous shift in tone, direction and message that realizes the ultimate sincerity that makes this story so touching. Kai's four chapters are the lynchpin that not only holds the Higurashi saga together, but also let the world know the full potential of Ryukishi07 as a writer.
