Shikigami Kooni

Oversouls and Attacks
By using a Shikigami summoning technique, which is his speciality, Yohmei can create and control any number of these small Over Souls using small leaves as their mediums. Yohmei almost constantly uses these, even outside of combat, to do small tasks like fetching items, holding the newspaper, and so forth. However, if he so wishes they can send verbal messages or even kill people, if they have sufficient numbers. These spirits don't appear to be particularly smart.-

This is Yohmei's favoured technique which creates countless Shikigami Kooni, that he can then use to surround an opponent and attack them from all directions at once.
