Damn, why did the girl friend have to die? In a weirdly stupid way as well. I kinda wish the author keep her around for a bit longer. It'd be cool to have protagonist antagonize over her and torn between two worlds.
I initially thought she is a woman at first then I duped myself into thinking "Oh, it's that kind of manga with cute trap-like guy". Glad to see that I was wrong ?
