Kuunaga (空流, "Void Current"): Is the process of creating spiritual links between objects or people. Spiritual energy flows through one object and is attached to other. This spell serves as the basis for many spells that target an opponent without any obvious effect, namely mind-affecting effects. When applied to destructive magic or other forms of physical attack, it grants it homing characteristics. This spell is used extensively when creating unique spiritual devices such as talismans and the like.
