After taking Mifune's lethal blow, Black Star finds himself deep within the soul of the Enchanted Sword, where he is devoured by the souls fallen by the blade. Instead, Black Star accepts the burdens of those slain by the Enchanted Sword and vows to fight for them, finally mastering the weapon, and, declaring that he will take the path of neither the warrior nor the demon but his own, defeats Mifune. Black Star then spares Mifune and continues to invite him to be a teacher at the DWMA, and they soon set off to find Angela. Meanwhile, Free, Eruka, and Mizune flee from Baba Yaga's Castle after sensing the demise of Medusa. Meanwhile, wishing to repent for helping Arachne, Eibon uses a key created from his own soul to activate "Brew", which has been revealed to grant the desires of whoever uses it. Lord Death uses the Magic Tool to transform Death City into a giant robot, desiring to personally fight for others, and swiftly enters the battle. Baba Yaga's Castle immediately becomes mobile and fights Death City, but Death City eventually manages to breach the castle, grab Asura, pull him out into the open and consumes him, apparently trapping him inside the city.
