That's interesting, because aside from Bakuman, The World Only God Knows, and Koe de Oshigoto, I'm only going to be watching sequels.
Bakuman - huge fan of the series, the characters make the show
The World Only God Knows - If I don't Arch won't leave me alone until I do, plus I'm a fan anyway.
Koe de Oshigoto - Ero-game Seiyuu? I'm there.
Letter Bee 2 - With that kind of cliffhanger and another dozen or so mysteries, there is no way I'm missing this.
Index 2 - A given.
Sora no Otoshimono: Forte - Stupid slapstick series with occasional dark and very serious undertones gets its much deserved sequel.
