Ransōtengai

is a rare Quincy techniuqe used by powerful Quincy.

Description
This is a high level technique that allows the user to control their body parts using strings of spirit energy controlled by their brain, forming lines or strings out of countless reishi. By using this technique, the user can control their body as one would a puppet, allowing them to move freely despite paralysis, broken limbs, or any other force that would impede normal movement. It was originally created to allow elderly Quincy to fight effectively, and is rare enough that Mayuri had never encountered a Quincy (out of the 2661 that he examined or studied) who could use it before Uryū. Mayuri stated it as "the most powerful technique for the Quincy," but he did not know of the Quincy: Letzt Stil, which means as far as Mayuri knew it was the strongest.
