I like the art, and I think Shirogane is gorgeous. My problem with this story is that I've read it before in other manga (like Undertaker Riddle... yes, this one has been released after MF but still). And Akira is not very likeable. But it is a good shounen, it has battles, monsters (ghosts?) and an interesting concept, only not very well developed. I am pretty sure the anime is more interesting.
