Spoiler for spoiler:

The loli teacher had to reveal Lemmy's identity and that her ability wasn't what the loli teacher made up earlier (I think compatibility?). However, I don't think she said the other girls had to like Kazuki for Kazuki to use magic. Otherwise, the principal shouldn't be so stupid to not notice that Kazuki used Kaguya's power (albeit the 1st level).
