The characters are all really bland, specially the mc, I think you tried to take some inspiration from anime characters as you mentioned anime quite a lot of times in the novel, but your characters don't have or show a lot of emotion and come off as shallow and you can't really connect with them. The worldbuilding or magic system is not very good so far either. Just some constructive criticism for points to work on Author, it's pretty good for a first novel, you just need to make some more efforts.
