Mechanical Light Shield Block

This chakra shield can be installed in any puppet. A mechanism inside the puppet opens its arms into a couple of segments, through which the user radiates their chakra. The chakra spreads out like a thin film and turns into a protective sheet, blocking all physical attacks and some techniques. While the shield does block Iron Sand, it does not prevent it from seeping into the joints of the puppets, which leads them to being disabled. Chiyo installed one into her own arm and into the puppets of Sasori's parents. Kankurō later installed one into Sasori's puppet body.

Trivia
