Nine Schools Competition IX is the sixteenth episode of the Mahouka Koukou no Rettousei anime.
Tatsuya and Masaki's teams face off in the final match. Despite knowing that with the rules standing, Masaki's abilities surpass his, Tatsuya confronts him head on, resulting in a spectacular duel. Making a critical mistake, Masaki breaks the rules by accidentally using a lethal attack on Tatsuya. Tatsuya manages to defend partially, but is hit and seriously wounded. However, he uses his self-restoration to overcome his injuries and while Masaki's still in shock from allowing himself to make such a mistake and/or possibly killing his opponent, Tatsuya incapacitates him at point-blank range. Meanwhile, Mikihiko faces off against Cardinal George in a lengthy duel, during which Leo helped Mikihiko only to be hit by Masaki's spell. Mikihiko finally defeats George, but is on the verge of losing to the third member of Masaki's team, when Leo manages to deliver the final blow, allowing First High to win the match.
