Kore ga Watashi no Goshujinsama, Kimi ga Aruji de Shitsuji ga Ore de Recommendations
One has a Brother and Sister and the other has Two Sisters, but they're both running away from their parents. At first the viewer is not shown why they left. But they both end up being maids/butlers for pompous rich folk.
Ecchi everywhere, comedy, maid-butler and those kind of relationships, what more do you want?
Both center around the whole master servant thing...only this time the master is a female and the servant a male.
If you liked Kimi ga Aruji Shitsuji ga Ore de or better known has They Are My Noble Masters, than you'd probably will like He is my Master because....both are similar how they both deal with kids running away from their home for one reason or another. And end up becoming a butler/maid they both have Ecchi and maids of course and a Harem feel to it and Perverted Masters in them.
Both Anime has the maid and master theme. In both anime the main characters ran away from home. The main characters in both anime become maids to rich masters. He is my master is a bit more of a comedy aproach to the maid anime genre than Kimi ga aruji de shitsuji ga ore de. Both anime are good but I prefer kimi above he is my master.
