It has been suggested that this article be merged with Chakra Threads for the following reason: Either we do this or we create a separate one for Chōmei's usage. Please discuss this on the appropriate talk page.
This is the article on the Fūma clan technique. If you are looking for the article on threads used in the Puppet Technique, head to Chakra Threads.
This is a murder-suicidal technique. The user creates threads of chakra that are used to connect the user's heart to another person's. As long as the two are connected, any internal damage done to one will also be done to the other. This ultimately means that, if one person dies, so will the other. Only a kunai wrapped in a special Fūma clan tag can safely cut the threads and free the two.
