This manga offers unique approach to exploring urban legend an weird unique stories, from the point of main character who explores them and maintains a web site dedicated to them. It is an interesting read if you like mysteries and urban legends, and worth sparing time to read.
In first chapter of the manga art is way better than in the rest of the piece, but that doesn't destroy reading enjoyment. As for the story, manga consists of only 11 chapters so there wasn't place for deeper characterisation of main character Kudan, but enough to highlight his main traits. Mysteries and interesting storyes he explores are tense enough to leave you wandering what's going on. Overall I give it 7 (good), for it was a good read.
