Poor plot and story.
Introducing a School arc so late in the history is very strange, and the way Bell was introduce to it is quite absurd. In a time when Hestia Familia responsibilities skyrocketed, we see this school life going on. The plot between the Tulle's sister is wasted, and the way Bell has to lie and use a bunny costume is ridiculous. So many contradictions with the rules the author set in previous volumes, we find now even another level 7 adventurer that no one knew about.
