The only thing that matters about "The Misfit of Demon King Academy" is that it does reveals in the worst way possible. Most shows will basically start with a premise which you can intuitively understand. Then, after you have understood the "norm", the show progresses and reveals something outside that norm to show how impressive something is.
The Misfit of Demon Academy doesn't do any of that. It pulls something out of thin air then tells you "ok please give a shit about this". It tells you "this is cool" and you're just supposed to accept that.
The best example is when a teacher does a magic circle, Anos (the MC) says "ok but its 4x better if you do this". Then he wiggles his fingers around changing the magic circle. The teacher then goes "Oh my God wow". This is where the show's creators order you to be impressed. Is it impressive? I don't know. I don't even know what the magic circle is or what it does. I guess I'll take the teacher's word for it.
Most of the show revolves around how Anos is cool. The pattern of the reveal above repeats a bunch of times. Although sometimes, at least it's convincing As for the plot, I don't really know what is the overarching goal or point. Anos is just doing stuff to do stuff.. I'm not sure what I'm supposed to even care about. Even the show isn't sure if it cares about the story because it just keeps speeding through it.
The only thing I will grant the show is that it's not boring. It's bad.... really bad. But stuff happens a lot so I didn't feel bored
