Infobox:Ryuuki

Ryuuki is a mysterious tailed beast who appeared out of no where. He seems to have an unending hatred for the world. Especially for Otohime and her tailed beast, but no one yet knows why. He has become famous very quickly because of his ability to take on a human form, despite being a tailed beast.

Chaos Release
Chaos Release is a very destructive Kekkei Tōta that allows Ryuuki combine Fire, Water, and Yin Release to create and control highly destructive blue or red energy.
