I loathe
Death Note but I love
One Piece so it was with mixed emotions that I approached this Death Note/One Piece crossover:
Life Note It's more of a ficlet than a story and I didn't find it emotionally satisfying -- Light survives -- but I did think it was interesting and worth a read.
Another crossover -- yes, I'm pervie that way -- I've been following is:
A Godfather in Gotham It posits, "What if Bruce Wayne was Hermione Granger's godfather?" In the first four chapters there hasn't been any real antagonist but I think chapter four has a nice set up so, hopefully, one will be appearing.
