After observing the behavior of Mibu and the Kendo Club, Tatsuya concludes that the person who attacked him must be a member of the international anti-magic political organization, Blanche. Miyuki is infuriated by Blanche’s attempt to further the rift between Course 1 and 2 students. Meanwhile, Honoka and the Girls’ Detective Club identify the attacker as Kinoe Tsukasa, the captain of the Kendo Club. They begin pursuing him but find themselves surrounded by a mysterious bike gang. They try to use magic to retaliate, but are pushed into a tight spot when the attackers use Cast Jamming to nullify their spells.
