Actually I liked this manga but the sadly plot was shut down in order to keep this story so short. There is a nice plot but you could make so much more out of it! I have read Dia Game because of the vampire stuff but was a little disappointed how vampires (especially the protagonist) were presented and how the whole transforming-into-a-vampire-thing was arranged (also like a run through the plot). There is no character development, but a turning point which was kinda suprising. The Art is nice and since it is so short it won't be a waste of time to read it.
