Hinamizawa Teiryuu-jo -Higurashi no Naku Koro ni Genten- by Ryukishi07 & TOMOZO, 1/1 volume, complete. ENG scans by xPearse. This is apparently the prequel to the whole Higu, haven't read it yet, so I don't know how full it is of spoilers. This is a different from the another release already uploaded. Enjoy!
