Fōrun-juu (フォールン獣 lit. Fallen Beasts) are a classification of Souls and Humans born with animal-like abilities. Much like the Visored, who possess an Inner Hollow, the Fōrun-juu possess an Inner Animal that represents the animal they most closely resemble in nature. Riki Nagakura's Inner Animal, for example, is a wolf, whilst Karis Nishiki's was a rabbit. Unlike Shinigami, whose weapon of choice is the Zanpakutō, a Fōrun-juu utilizes a Culmine.
