Akuto Sai enters the Constant Academy for Magick Arts hoping to become a high priest and change the world for the better. But when the school's oracle declares his future profession to be 'Demon Lord', he finds himself feared and hated by the entire student population. Now, instead of making comrades and studying for his exam, Akuto finds himself fighting off monsters, bullies, and well-meaning classmates in various states of undress. If navigating a magical high school as a transfer student wasn't difficult enough, Akuto now has to deal with a cute android ordered to observe him 24-hours a day, the precocious attention of the flying, invisible and naked Keena Soga and the advances of the school's most popular girl. Will he be able to overcome his fate, pass his classes, and mend his friendship with the violent Junko Hattori, or will he succumb to his demonic destiny?
Both of these are about a seemingly ordinary guy who has very special powers. The male lead in each story winds up attending a female dominated magic school, where they discover that he is an extremely powerful person foretold by fate. Those around him fear he will become an evil overlord & set out to stop him, yet he only wants an ordinary life.
Both series have the same basic plot, which is: A guy gets transfered to some kind of magic academy; There he learns that he is some sort of demon lord (you know an end boss) and that he is insanely powerful. Because of that he quickly attracts the attention of several powerful girls there at the academy and thus his harem is born. The female characters in both series seem to follow the same archetypes and (oddly enough) the male lead is fairly cool (which is not all that common in harem series). I don't think I need to add that all that makes those series very similar. The thing is, those manga were written differently, so even if you liked one of them it's not a given that you will like the other as well (nonetheless you should give it a try regardless).
Ichiban Ushiro no Daimaou and Amaenaideyo!! Involve lots and lots of fan service. The main heroes of the story at first appear to be very weak characters but work their way up to the top using magic.
One guy, a harem and comedic antics mixed with action, stir well. Sift some tsundere into the batch, fold with the contents of a school life outside regularity (Infinite Stratos two parts mecha with excellent gym wear and Ichiban Ushiro no Daimaou with it's school of magical youngsters, two parts) and season with drama to taste. Results are a harem/comedy with action, a breakout character in the harem that's genre-savvy, and some badass moments.
If one finds that they enjoy the end results of one, they should make sure to taste the other.
Years after having been exiled from the Kannagi household for being unable to utilize their fire magic, Kazuma returns to Japan, only to discover that the Kannagi family's very existence is threatened. Unknown to them, during his absence, he had become a Contractor and thus acquired a vast strength in wind magic. Not showing any remaining contempt for them, he offers to help solve the Kannagi household’s problems in return for large sums of money. Together with his younger brother Ren and the feisty heir to the Kannagi household, Ayano, he fights to protect those he cares about... for a price!
Ichiban Ushiro no Daimaou and Maken-Ki! are very similar harem series (similar setting and characters). Going into details would be pointless, but let me just say this: the first one has better premise and male lead, but the other one manages to introduce some plot at times. This plot, while not great, seems to be better than the plot of Ichiban Ushiro no Daimaou (even if by a hair). In my opinion, both of those manga are below medicore, but if you enjoyed one, you might like the other one as well.
