The Six Paths of Pain (ペイン六道, Pein Rikudō) is an Outer Path technique that allows a Rinnegan user to manipulate up to six bodies as though they are their own.
To make full use of the body, the user ideally transmits their chakra from the highest and closest point possible so that they can have the best possible range.
Once their chakra enters the body, they are given complete control of it, allowing them to decide all of its actions, its use of jutsu, and even speak through it.
When multiple bodies are controlled together the user is able to see through all of their eyes, thus registering six separate fields of vision at the same time.
