(If you read and liked "Hanatsuki hime" you will most likely enjoy "Ipaasha", and vice versa.)
Overall - For a one-shot, Ipaasha was very well thought-out and the characters were developed at just the right pace. One of the main reasons I liked this manga so much was I couldn't predict the end! This is one of those [few] mangas where you can just relax, go with the flow, and let the ending surprise you.
Story - Good story, quite original in some aspects. Everything went very smoothly and there was no loose ends.
Art - OUTSTANDING! I rarely rate art a 10,
but when I do, it's definitely beautiful and pleasing to the eye. You'll be addicted from the first page!
Character - again, the characters had to develop quickly, because of the story's length, but nothing happened too quickly.
Enjoyment - 10+!!!! I wish I knew of more mangas like this one!
