I've got several on the go at the moment, including One Piece, Danshi Koukousei no Nichijou, Kuroshitsuji...and others I have forgotten. I've been so busy lately, so I haven't been able to catch up with them for a while. I'm looking forward to the time when I can finally sit down and enjoy anime again.
Konjiki no Gash Bell and Stella Jogakuin Koutouka C3-BU. I've also been meaning to watch Hyperdimension Neptunia: The Animation, but I still haven't started it yet.
In the middle of Rurouni Kenshin (Still, this show is long.), Kaze no Stigma, Attack on Titan, and finally, I'm rewatching Sword Art Online through Toonami's dub (Yes I am staying up until 1:00 every night to watch.)
