A ninja's strength does not lie in displays of power, but in the concealment of it. An Anbu mask is a symbolic nod to this philosophy, hiding a mighty warrior's power behind a colorful animal mask designed to look as harmless as possible. These masks are made of ceramic and feature prominently in "Naruto" where they usually distinguish a ninja of unusual power and, typically, malevolence. They are worn with a series of ribbons laced behind the head and under the jaw and, as long as they are in place, not only is the wearer's identity protected but an eerie dissonance is established between his or her capabilities and his or her appearance. You can use a "Naruto" Anbu mask as the crowning touch on an Akatsuki or shinobi cosplay, stepping into the shadow world of the ninja clans as a masked stranger all in black, someone to be feared when they are noticed at all and whose steps are all but silent. You can find an Anbu mask through the vast inventory of costume supplies maintained on eBay.
