When I first started reading this manga I really enjoyed. The art was great, I liked, what I thought, was the plot line and the general idea of the world. I thought the characters were great and really loved the 'dress as a boy' side f it. But I was unbelievably disappointed with the ending. It felt like I'd been scammed or something. It left out why Japeth had to dress as a guy. It left all possible relationships that were emerging hanging. It felt like it was cut off and it ended with a 'save-the-planet' thing. I get that we kind of need to save the planet and all that and liked that touch of it in the story, but if the author was all for saving the planet then she shouldn't have wasted paper creating this manga.
So overall, I've given it a three, despite the story, art, characters and enjoyment being high. I feel like I wasted an hour of my life.
