About time I bashed a 2010s anime, this is Demon King Daimao.

Akuto Sai is a wide eyed student hoping to graduate as the top student of a prominent magic academy but his world gets turned upside down where an aptitude test determines him as the future demon king. Ostracized by his fellow students and attracting a harem consisting of a ninja, an android, a witch, an occultist and a childhood friend who likes flying and stripping, Akuto decides that the system created by god needs destroying.
This series is messy, whoever was in charge of editing needs to be fired because the plot is so disjointed you can't tell where you are in the story and you feel convinced you missed an episode or two.
The actual harem is weak, Junko especially makes Love Hina's Naru look like a decent character in comparison.
I'm also puzzled as to why it takes place in a magic academy as it quickly drops that plot in favour of a corrupt government conspiracy, fate of humanity and ninja clan betrayal, they couldn't even rip off Harry Potter correctly and don't get me started on the ending.
Dub is cookie cutter of the time.
Is there anything I like? The student council has it's moments as does Akuto and the dragon Peterhausen but it's not enough to save this train wreck.
Final Verdict: They couldn't even rip off it's inspiration correctly, they couldn't get a decent harem, they couldn't make the action interesting and the ending is a kick to the balls, they couldn't even edit it properly. So yeah, this is proper anime trash and not the good kind.
