Jōno has the calmest, most composed personality of the Hunting Dogs. However, he does not take interruptions nor injustice lightly. Jōno hides a fierce temper behind composed expressions, mixing them with harsh threats and remarks towards his comrades. Tetchō Suehiro finds himself on the receiving end of much of these remarks due to his offbeat nature, easily aggravating Jōno. Jōno has a sadistic side to him in extracting information from his targets. Jōno thinks that he must be the strongest.
