The Dark Spirit of Chaos was created by negative emotions in its host's soul. This drove the host to commit crimes, strengthening the ka. The host was put on trial after a failed attempt to steal from the already-raided tomb of Akhenamkhanen. Shada spotted the Dark Spirit of Chaos when using the Millennium Key to look into the host's heart. Akhenaden used the Millennium Eye to expose the ka and Seto completed the exorcism by using the Millennium Rod to seal it within a stone slab.
