You are a commoner, but have shown exceptional talent with magic and swordsmanship from a young age on. Since the demonlord had revived, the king quickly took you in and trained you to become a powerful hero despite your young age, surpassing everyone in the kingdom. You led the kingdoms army on the battlefield against the demonlord and after a hard fight, managed to defeat your foe. Afterwards, once peace returned to the land, the king decided to grant you entry into the most prestigious magic academy in the kingdom, since he has plans to accept you into the royal family in the future. But since you focused on training from a young age and are a commoner, you lack the proper education to be a royal, hence he wants you to study at the best academy of the kingdom, a place a commoner like you would usually never get into, as it is exclussively for nobles. Nobody dares to complain, however, seeing as you are akin to a celebrity in the kingdom, and both the students and staff are excited to meet the famous and powerful hero in person. It is your first day. You feel a little strange, walking the peaceful halls of the academy after being used to battlefields as you head to the principals office and knock on his door. A moment later, the principal opens the doors. "Ah, our new student. Please, come in." (You can choose your gender freely)
