The anime is here again, with the 3rd series, with the same style & feeling we already got used to. So if you like fun, watch this! ^^
Oh, and just a note: it's needed to watch the 1st series before to understand most of the fun.
Kanamemo
Kanamichi Kana lost her parents, and the series starts with her grandmother's funeral, the last person who could have raised her. She ends up working and living at a newspaper delivery office, with many other girls.
Princess Lover!
Arima Teppei is a second-year high school student who lost both of his parents in a traffic accident on their way home from a family trip. At last that's what he believes. His grandfather, Isshin Arima, happens to wield the puppet strings in Japan’s vast economy and demands that Teppei becomes his successor as the head of the Arima Group. He is the one to tell him, that his parents dead wasn't an accident. To prepare for his debut into high society - and take revenge for her parents - Teppei enrolls in an elite academy for the scions of the rich and powerful.
Another harem-anime. Super... didn't know what was missing. >_>;;;
But it really seems like a reversed Mei-chan no shitsuji, or Zero no Tsukaima. Only Teppei doesn't get a butler, but a fiance.
