Suburi

Suburi (素振り, Naked/Unadorned Swing) is the term often applied to the practice swings conducted by those who practice of any sort. However, to a member of the Cáo's Branch Family, this practice constitutes the entirety of their lives. It is regarded as a phenomenon that, when Suburi is practiced by those who dedicate their lives to the refinement of their own blade, it will eventually reflect the mind, body and soul of the wielder, enabling to cut through anything they desire.
