DNAngel is quite good... At least one of the best mangas realesed here in Sweden.
Still, it's only on place 21 on my favorite manga list... Haven't seen anything of the anime though. O.o''
WELL! My favorite is... With! X3
Daisuke's too young and I don't think he's that cute either. Dark is... well, I don't find him good-looking or anything at all.
The twins are quite cute, though. But I still like With! Even if I stopped reading the manga long ago, I still say "Kyuuu~!" everyday.
