I Teach Melee Combat at Hogwarts

Aaron Kate, a battle mage from the demon world, was forced to become the Defense Against the Dark Arts professor at Hogwarts because he accidentally killed Professor Quirrell. He firmly believes that the best defense is to lift the opponent into the air and then follow up with a dazzling shot. He has achieved remarkable teaching results and is deeply loved by his students. Until one day, he was registered as a fourth grader in the school's admission book. As a result, Hogwarts ushered in the most chaotic year in history: the former professor sat in the classroom holding his textbooks, and the Sorting Hat was silent for half an hour before announcing that it was dead. While he was learning the levitating spell under Lockhart's boastful words, he was also setting up a "Fighting Art" class in the Forbidden Forest to teach students how to create dazzling lines on their hands. While everyone was nervous about the Chamber of Secrets and the Basilisk, Aaron had only one simple wish: he hoped that his score in this Potions exam would be better than that of the students he taught. (Professor McGonagall's friendly reminder: please new professors not to demonstrate the "Sky Strike" broomstick technique on the Quidditch pitch)
