Are the events in "sotsu" happening the first time?


I don't understand,

  * if Rika travelled back in the time and re-experiencing the events all over again that occurred in the 2006 series
  * or we are watching the 2006 season again from a different perspective so that we can solve some unsolved mysteries.

Can you please clarify this?




This is exactly the point of Gou and Sotsu:

It seems like it's a remake. Watch to see if it's really a remake or if it's
something else.
