I Even Ate Demons

With his attacks overpowered, Gyokko reveals his true form, a large merman-like being with lethal touch, before attacking Muichiro again. Muichiro remembers when Amane found him and his relentless training to become stronger, his perpetual rage pushing him forward. Using his enhanced speed and a self-taught Mist Breathing form, Muichiro overwhelms Gyokko and beheads him. His marks fade and he reels from exhaustion and the poison's effects. Kanamori and Kotetsu aid him; the latter was saved from being mortally wounded by Kyojuro's tsuba in his shirt, which Tanjiro had previously given him. Tanjiro, Nezuko, and Genya struggle against Zohakuten's dragons; Tanjiro is swallowed by one and nearly crushed in its jaws when Mitsuri arrives, slicing it apart and saving him, before she confronts Zohakuten.
