Ultimately Hard Absolute Defence: Shield of Shukaku

This defensive technique is formed by Gaara to create a toy-like replica of the One-Tailed Shukaku that is roughly thrice the size of himself. Because the replica is formed under extreme pressure and is built of the strongest minerals it is virtually indestructible, having yet to be penetrated by any force. As the name of the technique implies, this is Gaara's ultimate defence.

Trivia

 * In the anime, the attack variant of the Shield of Shukaku is the Ultimately Hard Absolute Attack: Spear of Shukaku.
