Demon Slayer: Kimetsu no Yaiba is now in the works for its big anime return with a third season of the series in the near future, but one awesome cosplay is showing off just how much happened during Season 2 by unleashing Nezuko Kamado's full demonic transformation! The second season of the series took on the Entertainment District arc from Koyoharu Gotoge's original manga, and this saw Tanjiro and the others pushing themselves further than ever before against some powerful new threats. Even Nezuko got into the thick of it too as she needed to unleash a deadly new power to help save her brother.
