Higurashi no Naku Koro ni

So I'm confused about something.

[spoiler=Only answer this if you know what's going on in the series.]Is this in any sort of order, seeing as Keiichi is killed in every chapter, but is alive at every start as if nothing's happened? >_>[/spoiler]

Each death usually signifies the end of an arc. I really don't think you want me to explain it to you, as it would spoil the series. However, I can say that everything that happens is related.
