An experimental tool of Yukigakure designed to be the ultimate technique for absorbing chakra, this device absorbs the chakra of a captured target when it is applied. The device also creates a force field surrounding it, which prevents it from being either removed or destroyed. These abilities prevent the subject from performing ninjutsu in a matter of moments after being applied as well as making the subject lose consciousness momentarily.
The subject is, however, not incapable of overcoming the device's effects; for example, a large burst of tailed beast chakra has been shown to destroy the device.
- This tool is unnamed in the movie, but Dotō Kazahana simply refers to it as the "device".
