I haven't seen any anime in a long time but the last I watched was like the first 15 episodes of Trigun and mabey like 5 episodes of One Piece. (I had no idea One Piece had a more serious version, where there's blood, cussing and other segestive themes. I always watched the more childish version on Cartoon Network.)

About 07-Ghost, I think I've read it, can someone tell me what it's about to jog my memory?
