Friends (S01E04)

After watching Mibu and the Kendo Club, Tatsuya deduces that his assailant is likely affiliated with Blanche, an international anti-magic political group. Meanwhile, Miyuki is enraged by Blanche's efforts to deepen the divide between the Course 1 and 2 students. At the same time, Honoka and the Girls’ Detective Club pinpoint the attacker as Kinoe Tsukasa, the Kendo Club's captain. As they pursue him, they unexpectedly find themselves cornered by a mysterious motorcycle gang. Attempting to fight back with magic, they quickly realize they're in trouble when the gang employs Cast Jamming to disable their spells.
