Unfortunately after reading this first, I found that The follow-up manga was a huge disappointment... I liked the original characters that Yasuki Tanaka had created, and loved how the plot went... Instead of "Childa", a lovable smallish character who is a slave same as the main Character Tsubame, "Jilda" is a major
in the army who is after Tsubame's life and also have gained a tsundere personality... I understand that Childa and Jilda are probably meant to be the same character, but they look different, behave different and do not fit to be the same character, and this complicates the manga...
Yasuki Tanaka has a rather unique way of unlocking the superpowers with keys. in the one-shot the keys are all the same, and thus allows a more free distribution of the keys, but in the manga the keys are all different which complicates the feel.
My overall impression of the one-shot is a unique story with a very good plot and potential to become a popular manga, but Yasuki Tanaka managed to remove some of the things I found enjoyable in the one-shot in the follow-up manga...
