Higurashi no Naku Koro ni Rei mostly centers around the character Rika Furude (Let's be honest when isn't she a part of the show in some way) and the ordeals she faces when she finds herself in a completely different world than what she's used to. The story details how desperate Rika can actually get when faced with an ordeal like the kind she's in during this OVA. I found it enjoyable because it gave a lot of explanation to everything that happens and so much more.
