can someone tell me that Higurashi no naku koro ni Special Nekogoroshi is the sequel of Higurashi no naku koro ni Kai? or is the Higurashi no naku koro ni Rei is the sequel of Higurashi no naku koro ni Kai, i'm really confused here, cause i didn't watch Higurashi no naku koro ni Special Nekogoroshi yet
