This looks interesting... but why is it a 'tragedy'? Don't worry, spoil me all you want - ...

It really is interesting, a very good manga and i would recommend it to anyone. The tragedy in most cases is when the kami-sama (paper dolls) return to paper (die) and that's tough on their kotodamashi (masters) who have been in love and attached to them. I would go on and explain the other tragic parts but i don't want to give everything away for other potential readers. But don't let the sad parts put you off, there are plenty other really good parts in it too. I would say that overall, the good outweighs the bad by far.
