Himura (日村 Sun Village) is a rogue zanpakutō spirit who was once a zanpakutō of a noble warrior within the Gotei 13. However, the ideologies which his partner began to form within his mind began to cause Himura to question the validity of his existence, and if he was truly necessary. If he was to be a tool to bring about "the end of all things", as he describes it, he would have no part in it. And thus, he cut his own soul off from the soul of his Shinigami, materializing in the form that he took upon in the Shinigami's Inner World. To sustain his existence in the physical plane and achieve his goals, he has been assimilating powers and energy from a number of species, as well as actively looking for a suitable individual to gain a permanent power source from.
