Gozu Tennō

The is a technique, developed by Root's Tanuki Shigaraki. Upon the mark being placed onto someone, the person will enter a contract with the Nue. The mark acts as a medium for absorbed chakra to be transferred into the Nue, as well as a gate through which it is summoned from a seperate dimension.

The true source of power for this technique is negative emotions. If the carrier of the contract loses these emotions, the contract will be destroyed.

Influence
The technique's name comes from Gozu Tennō, a Japanese deity of pestilence.
