Earth Magic

Earth Magic (地巫術, Jifujutsu) is a field of elemental magic that exists outside the realm of conventional Shinigami Kidō.

Shiba Style
The most common form of Earth Magic is the Shiba Style (志波竜, Shibaryū; literally "School of Shiba"), as the Shiba Clan are renowned as its very creator. The current successor to the Shiba Style is Ganju Shiba.
