This Caste was created by Hiro in order to boost his physical defense, and attack power. By converting all of his muscles into Island Clouds, Hiro then produces a thick ball of fog around himself, in which he absorbs the moisture from the fog into his now "cloudified" muscles. This causing them to become much larger, increasing his over all power and defense, at the cost of his speed. By using this form, not only has Hiro gained a wider range of techniques, he he successfully gained a technique which would protect him, and would allow him to attack at the same time.
