Since this manga has only one review I feel like I have to join in!
Basically, if you were kind of weirded out by the second season of Darker than Black, then just come and read this manga, and pretend it is the second season instead. The artist is the character designer from the show's first season, and his style is pretty neat. However, if you really go for the by-the-book standard style of drawing, then it might weird you out a little bit.
Either way, reading it is pretty much the same as watching the show, so I can't help but like it.
