Kamiusagi

The Kamiusagi (神兎) is an incarnation of the primordial entity known as Shinju; created from the gathered energies of the nine Bijū united together through the pure essence of Kaguya Ōtsutsuki. It was born within Seireitou Hyūga, as the two entities merged together and subsequently made the latter its Jinchūriki, becoming an even more powerful being of frightening capabilities.

Trivia

 * "Kamiusagi" literally means "God Rabbit" (神兎), a reference made to both Kaguya Ōtsutsuki's title as "Rabbit Goddess" and Seireitou's title as "Rabbit God".
