Puppet Sword Technique

The user attaches their chakra threads to the opponent's weapons covertly by making the threads invisible. By manipulating these threads at the ideal moment, the user can turn their target's weapon on them.

Improvements
By using the Magnet Release kekkei genkai to magnetize the target's weapons, this technique can be achieved without using chakra threads.

Trivia

 * According to Mitsuko Akechi, this technique follows the idiom of "biting the hand that feeds you".
