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.

the creators of lain have actually said that they intended that show for teens.

anyway the original poster should definitely try fist of the north star. it's probably the most kawaii maid catgirl series i can think of
