Anime and Manga
The Kantō Great Ape Alliance (関東大猿会, Kantō oosaru kai), referred to as the Hihi Clan (狒々組, Hihigumi) in the anime, consists of a large assortment of apelike yōkai. Due to the high standing of its former leader Hihi, the clan gained a great amount of respect and power.
The vast majority of its members, including the former head, were wiped out by Tamazuki's forces during the Shikoku Arc. The current clan head, Shōei, is in the process of revitalizing the clan and returning it to its former greatness.
