Mahouka Koukou no Yuutousei EP5 - I won't let anyone interfere

Blanche attacks the First High School, during which Honoka, Shizuku, and Eimi encounter several of its members and defeat them. Miyuki and Tatsuya see the trio apprehending them and advise them to follow the student council's evacuation order. Honoka, Shizuku, and Eimi notice Kinoe being accompanied by Blanche members and follow them. The trio defeats the Blanche members, except for Kinoe since he has escaped them, but he is later apprehended by members of the Public Morals Committee. Following the attack, Miyuki and Tatsuya decide to infiltrate Blanche's hideout. With Katsuto Jūmonji, Takeaki Kirihara, Erika Chiba, and Leonhard Saijō joining them, Miyuki and Tatsuya defeat the organization. Miyuki feels guilty for going overboard on using her Niflheim magic against the enemies, resulting in Tatsuya using his Regeneration ability to heal them, but she is comforted by her brother. Miyuki and Tatsuya's friends then celebrate his birthday. In a post-credits scene, students Airi Isshiki, Tōko Tsukushīn, and Shiori Kanō of the Third High School begin their training for the upcoming Nine Schools Competition.
