Deadlock Seal

A technique used by Juro Uchiha, this Fūinjutsu is a very complex and powerful technique which involves fully draining an opponent's chakra to almost zero, while also having the user's chakra being drained out of his body. The chakra of the opponent and the user then clash into each other, being locked into the seal permanently. Although both the chakra of the opponent and the user are sealed into the user's body, it is impossible to access the chakra, as it has been sealed away into another space altogether—permanently. Inevitably, the opponent passes out due to having virtually all their chakra (except a certain amount to sustain their life force) drained. The complex nature of the seal and its' heavy emphasis on a non-lethal solution makes it a very difficult technique to learn, let alone master, even for experienced and powerful Jōnin.

Drawbacks
While it never harms an opponent, the side-effects this technique poses to the user can be very severe, and even fatal if something were to go wrong. If the seal were to malfunction, the mixing chakra of the opponent and the user could be 'poisoned' by the seal, causing a lethal rejection in the user's body.
