I think that it's a nice manga ranked really low (#13369 on MAL with a 6.64 score) and axed really quickly.
Story: Since Yuna was little she had unbeatable luck, is always happy, has a lot of friends but is an orphan. She still has an older brother and together they fight poverty. One day, Yuna meets a boy who demands that she gives the only memento she has of her mother to him. She refuses but a little later she expose the true identity of the boy and about the memento of her mother.
When I think of origami I think about paper folding... but... Wikipedia also says that ori means "folding", and kami means "paper" (kami changes to gami due to rendaku) so that's why in this manga we have a lot of gods (kami) but I still think that maybe another name would fit this manga better.
The story is well made and had potential to become a really good manga (sadly it was rushed/axed): the characters have a good background and a clear goal (return to their normal human life). The few characters are interesting and develop well, maybe because there aren't a lot of them and the side characters are really few. The story is quite simple and enjoyable.
The drawings are well made and cute. Every page is well made, good to look and with a lot of details.
My rating: 7/10
It had potential... a lot of potential but sadly the ending was axed and the ending was left open... it's still enjoyable but an open ending after we discover that "only one will be left" is a little unsatisfying. We can see only one death and the main enemy is still there doing who knows what because we won't see him again. And we won't know who was left in the end because all of the main character left together for a journey to find all the Mitama.
