Secret Technique: Secret Box

A collaboration technique utilized by 's henchmen; the four men create a square with their positions and perform the required seals. After that, cubes rise from the ground, each one below each user. These release a stream of seals that connect the four cubes in a square shape. An invisible barrier is created. Anyone inside the barrier is unable use ninjutsu or techniques of any sort, however, the casters may create exceptions. The downside of the technique is that someone overwhelmingly strong can break it with their chakra alone and no caster can perform any additional ninjutsu while focusing on the barrier. If a single member is interrupted, the barrier will dissipate.

The technique is named after the puzzle box, an intricate puzzle that requires the manipulation of several pieces to open a box.
