The 8 Purification Sake (「八塩折之酒」?; Yashiori-no-sake) is a special holy type of sake made from spring water from Hitoshio Spring in Agata Forest. It was used by Nagi 100 years ago to intoxicate Orochi to leave it vulnerable to attack. It is the only known substance capable of that. It is usually drunk during the Kamiki Festival which is held every year.
