Hand Maid May has elements of "ecchi," but all it mostly is is just simply panty shots and not much else. Sometimes this is applied to the humor of the show, and the main character, Saotome Kazuya, is the butt of all perverted jokes.
That being said, the story is good for this kind of anime. Not the best story ever, but the story was surprisingly flexible and allowed a lot of humor to come out of it. The characters are all very unique and likable, and each has his/her role in the series. The music is very nice and relaxing and fits the mood of the scene very nicely. For an old anime, the animation is very nice, especially all the intricate computer scenes. My only gripe about the show is that being only 11 episodes long, there are 2 episodes where all of the story is squeezed in to make the show sort of a drama at those episodes. However, a comedy like Hand Maid May feels old after so many episodes.
Hand Maid May is filled with lots of good laughs and each episode feels longer than 25 minutes of your life, however the series is unfortunately very short. A perfect 10/10 from me, because this show has its own special charm that simply captivates you into watching more.
