Geokinesis for Koukaku

(Reason: The source of their density appears to be the iron in the blood to increase their density, iron is a metal, metal is part of the earth (which is basically carbon and a colleciton of metals when boiled down to it). and carbon can be compressed into diamonts and other sturdy minerals.)
