Usage
There are many types of Yoki Manipulation : This type is used by: Galatea, Clare, Jean and the Yoki manipulating Awakened Being.
 * The first type: The user can manipulate Yoki on its opponents. The user can distort their focus, changing the trajectories of their attacks. But, according to Riful, the user can't fully control yoki to the point the user can completely halt attacks. The user's manipulation technique has no effect against full-powered attacks. If this technique is used by a strong user, the user can immobilize, manipulate and force Claymores to exceed their limits or even reducing the usage of Yoki to revert the oppenent back to its human form if used on a Claymore.

This type is used by Cynthia, Yuma and Clare. This type is used by Clare, Galatea, Renee and Rafaela.
 * The second type: manipulating other Claymores' or the user's Yoki to aid with regeneration and healing.
 * The third type: This type is actually part of the first but because it's more advanced and the results are a little different they make it a new type. The user uses its yoki to enter the mind of the opponent and uses this to awaken it or reform its shape or to transfer memories.
 * The fourth type: The user manipulates the opponent's yoki to make the opponent unable to sense the users yoki or presence. This type of Yoki Manipulation is a somewhat blend of Yoki Manipulation and Sensory Control. This type is used by Roxanne.
