Dreaming of changing the world for good, Akuto Sai transfers to Constant Magic Academy where he befriends a virtuous ninja clan member, Junko Hattori. On the way to the academy, they vow to make the world a better place together; however, the situation suddenly takes a turn for the worse upon his arrival—it is prophesied that he will become the Demon King!

As word of his destiny spreads, the school begins to fear him, and Junko's trust in him falters. While Akuto is determined to not let his predicted future control his fate, it seems as though everything he says and does only serve to reinforce the fact that he is destined to be the Demon King. Moreover, he is surrounded by a harem of beautiful girls who each have their own plans for him, ranging from bringing him to justice to simply showering him with love. With his newly awakened powers, Akuto must cope with his constantly growing list of misfortunes and fight to prove that his fate is not set in stone.

"That's why I decided not to think about anything anymore!"

That's a good one-line summary of this anime taken straight from the last episode. It's safe to say that the enjoyment of this anime is inversely proportional to the amount of plot stuffed into one episode. Simply, the more plot, the less fun. Ichiban is a harem anime. That means it doesn't exist to cater to the brain, and it doesn't. You should be aware that if you're going to watch this anime, then you're watching it for a good laugh, a small smirk, and moments where you can go "Oh Japan!" and laugh at what ...

Usually, when I start up a harem/ecchi anime, I prepare myself for the onslaught of nonsensical breasts, sporadic panty shots, illogical physics and random facesitting. These are the basics, and anyone who has watched more than one ecchi knows that this is a common theme in all of them.

And of course, naturally, these people don't go too hard on the show because "it comes with the genre," and "you have to look at it as a harem/ecchi."

I disagree.

There is a fundamental problem with ecchi anime that goes overboard. For an anime to be considered a good work, it needs to accomplish things such ...
