Using the Ketsuryūgan's abilities to manipulate a target's blood, the user can expand the blood in the target's body. Doing so, it will cause the body to morph into a much larger version, effectively disguising the target to be indistinguishable from their true form. By cutting their wrists to expel the extra blood, the target will return to their original state.
