I almost got confused with Overlord's tier system, lol. It appears that this academy has it similar except the higher the number, the weaker it is whereas a 10th tier spell in Ovelrord would be colossal. Overall excellent introduction chapter. I didn't get bored and surely, the direction of the story is something I'd long for, even if I haven't seen Irregular Magic Highschool or Chivalry of a Failed Knight. 👍🏻
