Well we've got a thread for what anime you're watching, but not manga. Figured I'd start one.
I just finished Death Note volume one and I must say, it wasn't that great(though it did help me improve my back stroke!). Quite the not so thrilling conclusion I had hoped for when I first began this series, but it had been going down hill since volume 7. anyways.
I also started JUNK: Record of the Last Hero by Kia Asamiya. Asamiya's artwork is good(he can't draw faces though...) and the story is decent, though it lacks any real depth at this point. But I'm enjoying it none the less, and I intend to pick up further volumes of it soon.
