This was an incredibly strange manga, that could best be described by the word "huh?" I like the general premise with the power being related to words on paper and it being used as part of a slice of life romance type story. I was also fine with how Aiba was kind of crazy, and the mechanic of what others believe to be a supernatural occurrence actually being a completely different supernatural occurrence, because that is a pretty interesting thing to think about. However, as we approach the ending, I don't think the ending is clear at all. I kind of get it in terms of plot, wherein I think half of it is simply delusion, but rather I don't get what the intention behind such an ending was in that it just seems completely random. In terms of plot, there really isn't much there to it with the plot just sort of fizzling out, which seemed fine at first because it seemed like the manga was trying to convey a message. But in the end, there isn't really a message either. There's some themes throughout the work relating to the value of words, and also of questioning what reality really is, but the ending doesn't seem to try to hone in on presenting a message related to these at all. Rather, the only message I could really think of was that you shouldn't mess with people, because they might already be a little bit crazy on the inside, and messing with them might make them a whole lot worse, which I suppose is good advice, but not one that doesn't really fit as the core theme here. The art was okayish. 

tl;dr: A manga that in the end doesn't seem to have much of a point.
