This needs an editor. The story is interesting to me, but the writing quality is low. Edit the story for consistency, grammar, and spelling. Make an appendix with the power levels, so people can look a that before the chapter where the MC explains the power levels to her new students.Also the people other than the MC will need descriptions. Names, ages, gender and power levels are all that is discussed. In order to keep track of characters I need more than that to visualize them. Otherwise the names just blur together and I can't differentiate them.
