This manga is very well drawn and has a great plot. It isn't just some random adventures put together. I like how the maker builds the characters. It is very easy for me to actually picture the characters as of they were next to me, they aren't too silly, too tragic, or too ignorantly happy. The plot does get thicker and actually seem like it has a set direction, not just changing as it goes.
It also has great values behind it for example, don't mistreat your things/dolls. It teaches one to treasure what they have, because of they don't it might turn around and be ruined. There are also many other great aspects about this manga. I suggest you read it and give it a try!
(P.s. the two main dolls are hot too.)
