Will Detachment

An advanced method of materializing one's will, Kaguya Ōtsutsuki was the first to demonstrate the ability to actually breathe life into her materialized will; having detached a part of her very essence in the creation of a new life form named Black Zetsu, whom then began a centuries long plan to resurrect the goddess. Kaguya's sole transmigrant, Seireitou Hyūga, has also shown competency with this technique. It allows for its user to actually infuse certain aspects of themselves into the materialized will that has been given physical form; these may include skills, memories, knowledge, personality traits, energies, and even techniques. However, they can also be bestowed with specific commands and purposes in order to act according to how their master had determined for them, such as in the case of the Zetsu creations.
