This manga is about a high school teacher who is also secretly a sorcerer taking on a gyaru student of his as an apprentice. The plot is mostly just random nonsense without any sense of flow to it and is full of plot holes and contradictions. The world building is incredibly generic with the a hodgepodge of a bunch of common tropes and concepts. The cast is also incredibly shallow with character development that doesn’t make much sense and relationships that go nowhere. I could go into more detail, but that probably isn’t a good use of anyone’s time. After all, I don’t think anyone actually expects a manga like this to have good writing.
The bigger problem is that the ecchi and comedy in this are barely passable. The ecchi suffers from the art in general not being very good. But even beyond that the framing used doesn’t show things off all that well and the ecchi situations just aren’t all that interesting. The comedy is rarely funny and is very repetitive. As a result of all this, the cast isn’t really likable or worthy of getting invested in either. Thus there’s nothing about it that’s particularly awful so its better than nothing, but there’s just not that much value here.
tl;dr: An ecchi-comedy manga with pretty mediocre ecchi and comedy.
