Eh... Um... I hate to judge a manga on only one chapter, but... for her to go from trying to kill the man that killed her father to joining him in so few pages with such little dialogue is just... For fuck's sake, no. I'm sure someone on this planet has that little conviction and changes their mind that rapidly and to that degree, but they are also probably troubled to begin with.
@SandyBleach said the idea and world is good, but the writing isn't and I have to agree with what I've seen. I might read more, but the first chapter made a... VERY... bad impression on its quality to me.
