GE Animation 31500 Naruto Shippuden Shinobi Allied Forces Army Headband

At the suggestion of the Fifth Mizukage, the five Kage agreed to merge their intelligence unit into a single, separate organisation, to optimise the processing and sharing of new information. To show their unification, Mifune has designed a forehead protector with the kanji "Shinobi" on it. All members of the alliance wear this in place of their original forehead protectors, to show that everyone is truly united under one banner, as opposed to being separated into five different villages. Most members of the alliance also took to wearing the basic uniform of their village, albeit with the new forehead protector to unify them.
