Shounen anime recommendation

Hi, my name is Anonymous and I love shounen anime, Love Hina style. I have watched and loved Love Hina, Maburaho, Negima, and others, as well as the slightly more original Midori no Hibi.

Can you name more harem anime for me? Complete with loads of fanservice and domestic violence if possible, thanks.

Rozen Maiden

Magikano is pretty good
