Frankly, I was a little scared to pick up this book, considering the reviews that friends and critiques have given this. But, after reading it, I was very surprised at how much I enjoyed it. For a horror about an unknown extraterrestrial being, I found it bone-chilling. Some shots made my blood go cold and curl up from how disgusting/horrifying it was. Though, in retrospect, the characters and some of the plot felt basic and bland. I think most of this manga strives from its imagery and horror through circumstances. Regardless, I believe everyone should at least give this book a shot; it was verywell worth my work breaks to read.
