Great Mirror Technique

 is a technique granted to the Mangekyō Sharingan of Tsuna Uchiha.

Usage
In order to use this technique, Tsuna's Mangekyō must be active. Any technique that he was seen of his opponent, he is able to mirror it, and use the foe(s) technique to his own technique. However, it seems this technique can only use the opponent's technique once. Therefore, if they wish to use the technique again, the form would need to preform the jutsu once again.
