One of three surviving crew members of Anita, Chaoji was seen reacting with Innocence, which was sent into the ark by Tiedoll when Lenali fell into the arc, and so was able to become an exorcist. Chaoji's Innocence, as of now still unnamed, is a pair of linked bracelets on his left wrist. The only power it has shown so far is to grant him superhuman strength on that arm, allowing him to pull the Allen, Lavi and Kanda all of out a bottomless pit they nearly fell into in with one pull, sending the three Exorcists flying.
