Five Elements Seal

Five Element Seal is a technique which produces a powerful seal that is used to block or disturb the flow of chakra in a target.

Usage
Once the seal is completed, the target will become unconscious and unable to fight for a short time. Orochimaru performed this technique to tamper with Naruto Uzumaki's seal. The original seal allowed a small amount of the Nine-Tails' chakra to always mix into Naruto's, but the additional seal disturbs this, preventing Naruto from using the Nine-Tails' chakra or even controlling his own chakra properly. This is because an odd-numbered seal creates an imbalance when placed on top of an even-numbered seal. When Orochimaru later notices that the seal has been removed, he remarks that there are very few ninja capable of doing so, like Jiraiya. Also, in the anime, it seems that Kazuma was able to learn this technique or something similar and use it on Sora to tighten the seal and then eventually remove it to unleash a power within him
