Hypnotic Genjutsu: Wild Beast Communication

By exhaling the Kotarō that their bodies are able to produce, members of the Kodon clan hypnotize Rōen, putting it under their control. Most forms of attack that might be directed against Rōen won't disrupt the hypnotism, but large quantities of blue fire powder will. The jutsu can also be used on those that Rōen has been sealed into, dulling its influence over them and altering their memories if desired. If anyone else inhales the purple smoke, they will simply lose consciousness.
