Earth Magic

Earth Magic (土魔法 Tsuchi Mahō) is a Caster Type Magic which utilizes the element of earth.

Description
Casters use the earth around them to attack or defend, giving Earth Magic users a great deal of flexibility when using their Magic. Skilled users can manipulate the physical properties of earth, such as making sand as hard as metal, creating iron-hard rock pillars from the ground, or even bending the ground at will and turning it into a liquid form. Earth Magic also enables a user to literally dive into the ground (be it rock, concrete, or metal), using their hands or feet, and tunnel through it. Earth Magic is a strong magic and is immune to Water Magic.

Like other elemental Magics, some users can also transform their bodies to earth to traveling through solid obstacles and underground. In the manga, Jura's arms appear to turn into rocks, although it is unknown if this transformation is caused by Earth Magic or advanced Transformation Magic.
