He is My Master is basically a somewhat ecchi comedy. It takes the scene with a 14 year old boy who has lost his parents in a car accident and inherited a huge inheritance. With the money he hires two sisters to be his maid but later on gain another one totaling to 3.
Now first the maid were happy that they could work there but soon find out Yoshitaka is a total pervert and constantly sexual harass them. Now the older sister that is constantly sexually harassed, Izumi, tries to quit, but Yoshitaka quick perverted mind came up with a plan by making her "accidentally" breaking stuff in his house that cost a lot of money so she becomes in debt to him. And has no choice but to work for him. There are a lot of ecchi moments but not so much on the humor. The supporting characters make a good first impression then disappears as soon as the chapter ends.
The artwork is fairly decent in this manga. The surrounding backgrounds and the character designs are quite great, but not spectacular. The buildings are drawn quite nicely and the clothes are fairly decent.
There is a lacking of supporting characters and side story you might say that should be typical inside a harem/ecchi comedy. The amount of character development is something this manga lacks. Many of the chapters are quite repetitive of each other as how it starts and how it ends. And the reoccurring joke of "lets have a battle" by Mitsuki gets old sometime, also with amount of pervertness Yoshitaka has can gets annoying too.
For the enjoyment, I thought it was ok, kind of good, but not great. I really liked the concept of the story. In the beginning it seem like the manga could go somewhere but it slowly lost its attractiveness as I read on. The jokes were getting kind of old, but I have to admit that Yoshitaka numerous attempts take the pervertness to the next level is pretty clever, but what I saw that it deeply lacked the character development and the supporting characters and side story compared to other manga/anime of the harem/ecchi comedy genre. Well I did enjoy it to a certain extent and hopefully you might as well too. read more
