Shikigami

Shikigami or Shiki are invisible ghost-like creatures that inhabit spiritual places. They are mostly contracted by means of ceremony and can become visible by banning them into small, folded and artfully cut paper manikins, allowing the users to utilize their powers. Shiki's come in different shapes and sizes with different abilities, some being able to possess animal's and humans to manipulate them. Monk's or those without any magical prowess can utilize Shiki's better than those with magical abilities.
