I was excited to watch this anime because of the high reviews everywhere, but I was very disappointed. I know it's a common theme in anime to have fan service, and many shows can live past that.
But for this show I cannot get past that they're constantly pushing minors and an adult professor to get together. I stopped watching after the beach episode because the MC professor said he "planned the trip so all the boys could see the girls in bikinis". It shocked me that this predatory behavior was not mentioned in any of the reviews.
The characters are also very unlikeable in general. The MC is frustrating to watch, and I get tired of the "trying to be cool" joke that they do constantly.
The two main girls are constantly annoying and make bad and rash decisions all. The. Time. The plot is otherwise very predictable as they constantly bring out the spell or gimmick ,that will give them the "gotcha" moment at the end, at the start of the episode. They don't even really try to hide it.
There are a million other fantasy-type shows that do not go full into the fan service and pedophilia, I suggest not wasting your time with this anime and it's terrible writing.
