-manga-
One Piece/GetBackers/Yami no Matsuei/Gravitation/Alichino/D. Gray-man/Togainu no Chi
(hmm I like my shounen ai |D;)
At the moment I'm totally hooked on Gintama the funniest anime I've ever watched XD makes me want to read the manga XD but of all anime I'm 100% one piece fan the manga and anime is as good imo. The 3 I would highly recommend are
-jigoko shoujo (hell girl dubbed)
Just amazing and it's so very Japanese ghost story style.
-One Piece
I'm biased because I was hooked straight away but there's a good mix of humour and action. Just don't watch the dub D: *cos wtf I wouldn't call it a kids show DX*
-Gintama
If it doesn't make you laugh wth is wrong with you. Whenever I'm depressed I watch it and it goes away for a while anyway XD.
