Ransōtengai

is a Quincy technique.

Description
A high level technique which allows the user to control their body parts using strings of Reiryoku controlled by their brain, forming lines or strings made of Reishi. Using this technique, the Quincy can control their body like a marionette, allowing them to move freely despite paralysis, broken limbs, or any other force which would impede normal movement. It was originally created to allow elderly Quincy to fight effectively, and is rare enough that Mayuri Kurotsuchi had never encountered a Quincy who could use it before Uryū Ishida, despite having examined or studied 2661 different individuals.
