This is a cute story about a crow wanting to be a human, so he can love the human girl in the same form. This girl had rescued him before when he was attacked as a crow. He makes a pact with the 'devil' to become human, but in return he has to do a 'bad' deed.
This is a cute one-shot, but the plot was way too deep to just cram into a one-shot. The ending felt VERY, very rushed, and so were the parts about the crow staying with the human girl.
The pacing was off, which I blame on the fact that it was a one-shot. The beginning was nice and read fine though. The crow (forgot his name) is a nice mellow character. Of course he has to be all bishie and sparkliness when he becomes human, which I think doesn't add anything to the story other than him feeling more confident. He had a deep personality though.
However, the girl just plain sucks. She might as well be a stock character, working in the background. The only thing we know is that she's ditzy (what an airhead), and that she rescues animals who are hurt. That's it. She doesn't have much going besides the stereotypical clumsy attitude that plagues the shoujo genre. Compared to the crow, she might as well not exist, she's a sorry excuse for a character.
The ending was way too rushed, as if the mangaka realized that she had a certain amount of pages left, and crammed in as much as she could within the last 3 pages. It felt way too rushed, and it really brings down the overall quality of the manga.
If this had more chapters (and more personality for the heroine), it would definitely be a great manga. But as it stands now, it's just a cute, but very rushed manga.
