We know that the "mini-arcs" in Higurashi (When They Cry) all start with a sudden rollback. After some terrible events, the town looks normal again.
Closer to the end of the anime we are being shown that
It's Hanyū who is responsible for the rollbacks, and she helps Rika keep her memories of what happened before the "rollback"
Now my question is about what those "rollbacks" really are. The wiki article, for example, says that they are
time travels, and what Hanyū does is reverses time to let Rika relive those days again.
However, when I was watching the anime itself, I clearly remember Rika saying that
what they did was traveling between "worlds", trying to find a "world" where everything was right (i.e. no murders).
Basically, if the first version is right, then
all the murders didn't actually happen, because the time was reversed each time. In the second case (changing "worlds"), however, all those murders would be for real in each particular world.
Was that possibly just a bad/false translation of the subtitles I was using? And which version is right, after all?
