Delayed Onset Ki Disorder (遅発性乱気症, Chihatsusei Rankishō) is a disease contracted from reckless use of one's ki. The illness bears similarities to a muscle spasm, and the easiest cure is rest. Even the simple act of the Air Dance Technique becomes difficult for experienced users to perform. Furthermore, stressing the body while ill in this way can damage the senses, causing them to never be able to fight again.
