Demon Shinki

This seed was created by Shinga and was once sealed in the Konoha Sealed Hall.

When under the of Shinga, it becomes a big tree, rapidly sucking out chakra from everyone within its vicinity and giving it to its master. The seed can be used as a recovery to give it's master near immortality and infinite chakra. The abilities granted are comparable to a jinchūriki. It is a very powerful and dangerous weapon capable of destroying even Konohagakure. When used by Shinga, the tree became a catalyst capable of increasing the power of his techniques to their very limit.

It was destroyed when its master was defeated and killed by Naruto Uzumaki and Sasuke Uchiha.
