Dustless Bewildering Cover is a ninjutsu based on the control of water vapor. With its help, the user distorts the light around himself and becomes invisible. While this technique is in effect, the very presence of the shinobi disappears: neither body, nor chakra that could be detected. That is why he cannot be detected either by sensors or by those who rely on heightened senses.
Mū mastered this cover to perfection, which brought him the nickname "Nonhuman" (無人). The name of the technique contains wordplay: its second part echoes meisai (迷彩) - "camouflage".
