Crona's loyalties are torn as Medusa regroups and plots to beat both DWMA and her sister, Arachne, in the arms race for Eibon's demon tools. As the madness of the Kishin continues to spread, Maka, Black*Star, and Kid begin even more rigorous training to master their weapons and work together as a team. Will they be ready to face Arachnophobia in time for their next mission? Or will internal strife tear them apart?!

Arachnophobia has taken the offensive and spreads the Kishin's madness throughout the world, using "BREW" to threaten anyone who stands in their way. In the wake of attacks at home and abroad, DWMA sends its top students to quell the madness and gather information wherever they can. But the madness is spreading much quicker and is stronger than they had anticipated. When confronted by an incarnation of the Kishin's madness itself, will Maka and Soul fall victim to the sinister Clown's manipulations?

While Black*Star and Tsubaki keep Mifune and Mosquito distracted, Sid is able to locate Arachnophobia's demon tool and put an abrupt end to their sinister plans. But though the evil organization won't be manipulating anyone's morality anytime soon, the blueprints for the dangerous tool are sealed away in Shinigami-sama's secret vault rather than destroyed. Surely Shinigami-sama would never think of constructing a demon tool himself?!

Tsubaki and Black*Star set off on their most difficult mission yet: a battle with the Uncanny Sword Masamune, a soul on the brink of becoming a Kishin. But this fight holds personal significance for Tsubaki - their target is her older brother. Jealous of her inherited talents, Masamune is holding nothing back. Usually docile and complacent, Tsubaki must find the strength to overtake the Uncanny Sword before she too is sucked into the darkness.

Cornered among the slabs of the Ancient Rock, Helmina comes face-to-face with Dust, head of the West District. With Jack Frost kept busy elsewhere, fighting the West's vicious pack of warriors, Helmina is forced to test the strength of her powers against the mighty lycanthrope. Alliances will shift and new powers will rise in the battle for dominance and the mirror image!!

At first, the residents of Ayakashi Hall are baffled by the discovery of a time capsule containing letters in their own handwriting, apparently from their future selves. But Natsume's ability to see beyond confirms the truth, and he is overwhelmed by the future he glimpses. The others aren't sure they want to know the full extent of what is to come when it has so obviously rattled Natsume and their later selves. Even with that knowledge, what can they do differently to face the Night Parade of a Hundred Demons?!

Kid's sense of order stands in sharp contrast to the unpredictable madness of the Kishin. But order and madness are two sides of the same coin. When Asura challenges the "tyrannical" Shinigami and his laws that serve to control humans' lives, Kid can feel the tendrils of madness within himself seeking purchase. The bonds of his friendships and his faith in order are tested to their limits as Asura makes his final stand against the forces of DWMA. When the moondust settles, who will emerge as lord of this world--Shinigami or Kishin?
