This castle is home to the Kaguya Clan of Kirigakure, or at least what remains of it. This rather bizarre clan is credited for raising shinobi like Kaguya Kimimaro. Members of this clan have the ability to extract their own bones and manipulate them as they see fit, using the Kekkei Genkai called Shikatsu Myaku. This ability also allows them to instantly grow new bones when they are extracted. The actual castle looks hardly any different from the other castles in the villages. About ten stories high with many rooms on each floor. The clan itself was long ago consumed by its lust for power. They tried to overtake Kirigakure, and were all slaughtered in a single night. All but one; Kaguya Kimimaro. When he died of Tuberculosis, the clan was presumed extinct, but in recent years, a small number of survivors have emerged.
