I just recently came across this new-ish manga from Hiroya Oku (Gantz), and was so absorbed that I plowed through everything that has been released so far (5 volumes) in one morning. It’s a mesmerizing and very dark take on what happens when someone suddenly finds themselves with fantastic (and mechanical) powers, good or bad. The two main characters are polar opposites, and both fascinating. I also love the highly detailed referenced art, which completely takes me back to my life in Tokyo (I recognize tons of places where I used to go often). It’s probably my favorite serialized comic right now, and it even pushed me to go and start reading Gantz (I’d seen at least the first movie, but had never checked out the manga).
