Consanguinity Activation

Activate the consanguinity and fuse the shikigami. Although it was just a simple phrase, as mentioned before, there were some prerequisites. In order to achieve a perfect shikigami fusion, it was best if the soul of the deceased was related to the living. 

In the era where the recuperation of reiki had not occurred, such blood relations were really hard to get. It was because most of the consanguinity of those who could turn into a spirit after death could not be trained. Moreover, a strong obsessiveness before death was required in order to turn into an apparition. These two prerequisites were already barely achievable. Moreover, the activation of consanguinity and the fusion of the shikigami were not an easy task.

The Japanese Onmyoji and shrine maidens devoted themselves in creating the path of the shikigami. It was aimed to enhance their strength and to break through the limitation on the strength of the traditional realm.
