Mahouka Koukou no Yuutousei

Synopsis

On the first match of the Official Mirage Bat event, Keiko Kobayakawa of First High School falls from the sky after her CAD failed to function, but she is saved by the tournament staff. Tatsuya deduces that the incident is one of sabotages against their school. He later restrains one of the staff members for corrupting Miyuki's CAD. A rumor about Tatsuya going violent is spread among other schools until Mayumi teases him for doing this for his sister's sake, resulting in other schools seeing the incident as him being a "siscon". During the second match for the Official Mirage Bat event, Miyuki uses the flying magic device developed by Tatsuya to win. After the match, she overhears her brother having a conversation with tournament officials regarding his flying magic device. Meanwhile, No Dragon Head decides to attempt to shut down the competition by sending their Generator agent, only to be thwarted by members of the National Defense Force. On the final match of the Official Mirage Bat event, Airi learns that the other schools plan to use the flying magic device after its information has been leaked by the tournament officials.
