- Alternative Hirukowashi-hen
Hirukowashi-hen was originally released with Higurashi no Naku Koro ni Rei as an extra arc. This version has several changes, namely the addition and removal of certain characters and removal of references to plot details not yet revealed in the Kizuna series.
This arc is based off of the Onisarashi-hen manga and is the second arc in the Advanced Story. It once again centers on Natsumi Kimiyoshi and her friends living in Kakiuchi City, with the detectives Tomoe Minai, Mamoru Akasaka, and Kuraudo Ooishi investigating the Great Hinamizawa Disaster.
