A story about suicide, rejection and psychological issues told in a very dramatic (and, in the end, rewarding) way. After the quick introduction of the main couple, the plot revolves around problems of the main lead (Kurokawa) and mysteries surrounding the female half of the main cast (Nanjou). Right from the beginning, it grabs our attention and holds until the very end. We wanna see all mysteries revealed (like why is Nanjou making Kurokawa ‘invisible’ by just clapping her hands, which sounds like a pretending game). All these behaviors have deep psychological background of problems that Nanjou is carrying. The manga develops its characters through their daily interactions.Curiosity of Kurokawa towards Nanjou grows every second and he desperately wants to find answers to many questions he has, but she refuses to answer (like why she pretends he is invisible).

It is understandable that not everyone is going to like this kind of story. The characters are behaving in a kind of unnatural way. I don't see it as a problem, since this is the way that was chosen to create a good story in a unique and special way. But I don't blame anybody who doesn't see it the same way. Still, if you decide to finish it, you are going to be rewarded with a worthy conclusion.

The manga contains a lot of nudity, so be aware of that.

Pretty quick and satisfying read, heavy on drama, suspense and psychological elements. You will get through it in no time, so it doesn't waste time.

Pros:
+ story keeps us hooked until the end
+ character development
+ quick and satisfying read

Cons:
- mostly for those who like this kind of genre

Double-edged:
+/- niche appeal
+/- the whole concept of "being invisible" may come about as weird
+/- use of fanservice and nudity
+/- many elements of writing may not appeal to a larger group of readers

9/10 (GREAT)
