Nine Schools Competition X is the seventeenth episode of the Mahouka Koukou no Rettousei anime.
A Mirage Bat player's, also from First High, CAD malfunctions causing her to fall. Tatsuya catches the culprit in the act of sabotaging Miyuki's CAD. The gang responsible for all the sabotage at the tournament decide to unleash a modified human with hopes of causing a massacre but they are foiled by two men and a woman. Miyuki uses flying magic to win at Mirage Bat. But due to concerns of cheating, the committee leaked the magic sequence to the other schools for the next round. However, it was found to be too much for the other competitors, as they did not have a sufficient amount of magic to sustain the sequence, resulting in the safety mode kicking in and lowering them to the ground, leaving Miyuki to win the game.
