Mudou (無道) was the former 7th seat of the Shadow Organization's Council of Twelve, though only for a short time. He unexpectedly slaughtered many young ability users at the organization's training facility and was killed in the attack, but chose to be reborn as an Ayakashi. Mudou was later both destroyed and resurrected by Masamori Sumimura, who was also appointed to his vacated seat by the Sousui, at Mudou's own suggestion.
