There's Something Very Wrong with This Magic School

Ren Algar traveled back in time to a game he had played. Edlund Magic Academy, a magic academy that was founded less than ten years ago, the biggest achievement currently is that it is allowed to expand its enrollment from one class to two classes. There is also a banner hanging at the school gate: "Congratulations! The college's enrollment has doubled." Now that you have traveled to the game, you will definitely have to face the protagonist of the original work. Facing a blond ponytail girl holding a dozens of meters lightsaber and wearing a protective shield Renn fell silent as he looked at the airflow entangled in his hand. "Stop singing!" Ren yelled at the song in his head. The mysterious singing voice echoes in my mind, the original protagonist with explosive output, professors with different teaching styles, the fun-loving senior sister, and various types of classmates. All Ren wanted to say was: "There is something very wrong with this magic school."
