And then there were three. Tanjiro, backed into a corner, is saved by Nezuko and follows the demons to their swamp.
Small-town Tanjiro is thrown into the bustling city life as his next assignment takes him to Asakusa, Tokyo where he picks up a scent.
The two demons named Tamayo and Yushiro, who came to Tanjiro's rescue, reveal a possible cure to turn Nezuko back into a human.
Tanjirou's arsenal of techniques barely holds Yahaba's final Blood Demon Art at bay. Think German Expressionism, only demonic.
Tanjiro meets a fellow Final Selection survivor, Zenitsu Agatsuma, on his way to his next assignment. Tanjiro hears the mysterious sound of a tsuzumi.
The owner of the tsuzumi literally rocks the house as entire rooms rotate at the whim of his instrument, separating Tanjiro from Zenitsu in a house of horrors - one of which is a man with a boar for a head.
Tanjiro's world keeps spinning as Kyogai's tsuzumi commands gravity itself with every beat, driving Tanjiro up the wall. Literally.
Kyogai defeated at last, Tanjiro finds Zenitsu battered and worn and holding an unconscious Nezuko before the dual Nichirin Swords of the man in the boar mask.
