Tiānwen (spirit)

Senji's Zanpakutō Spirit or more commonly referred to as Nanashi (名無し; Literally meaning "Nameless") is the Zanpakutō spirit the resides in Senji's inner world. He has yet to be fully awakened by his master. Due to his own immense reservoir of spiritual power he is capable of manifesting himself into the physical world and forcefully pull Senji into his own inner world to allow a chance to subjugate him. It is revealed when he manifested himself in front of Aya Kuzunoha and other members of the Gotei 13 that he is a Zanpakutō that possesses a rich and large history with Soul Society.
