Magika no Kenshi to Shoukan Maou is without a doubt one of the most derivative works to appear these two years.
A fanservice manga filled with busty curvy girls in short skirts and thigh highs and a single male character, Magikenshi follows the "Battle Academy Harem" formula without a hint of innovation or originality in its characters and setting and is completely unashamed of doing so.
You flat out will not find anything that this series does that other such series do not already provide.
All in all, an adequate intro to the tired Battle Academy Harem genre for a neophyte manga reader, but for anyone looking
for a gripping story, deep and interesting characters and an expansive background setting to be explored, look elsewhere.
