2016년 1월 16일 방영
Azuma stares in stunned shock at Oubu, now reduced to bones, as Hiiragi, Kogane, and the others successfully hold off Matobai. Hiiragi realizes this is the best chance to awaken Oubu and demands the heart Bubuki from Azuma, but Azuma insists he has no such thing. Believing that the heart Bubuki will react if its owner is in danger, he attacks Azuma with Iwatooshi! (Source: Crunchyroll)
