Mortar Release

Mortar Release (臼遁, Usuton; English TV "Cement Style") is a combined nature transformation kekkei genkai made up of techniques that mix wind and earth-based chakra to create both solid or liquid forms of concrete. It can be used both offensively and defensively, and is most seen in Yamagakure in relation to infrastructure. Mortar Release Techniques (臼遁の術, Usuton no Jutsu) are commonly associated with the Ram seal.

Forms

 * Some members of the Sugimori clan have been seen to manipulate their release to take the form of expanding foam.
 * It can be used in a liquid state to trap enemies. The weight of the mortar is heavy enough that it makes perfect 'quicksand' like traps.
 * For practical uses, it can be molded and shaped to form bricks and slabs for construction. It can be used in various other methods of construction as well, such as culverts, dams and lining canals.
