Onigari-no-Ryūō

The Onigari-no-Ryūō (鬼狩柳桜, lit. demon-hunting willow cherry) is an ancient sword in Higurashi no Naku Koro ni. It was bestowed upon Ouka Furude in order to murder her mother, the powerful Hanyuu. Upon Hanyuu's death, the sword was sealed inside a statue of Oyashiro within the Furude Shrine.

The sword appears in Higurashi no Naku Koro ni Sotsu, allegedly able to kill "beings who live in loops." It briefly becomes the center of a fight between Rika Furude and Satoko Houjou.
