About the characters: some of them are designed in a very questionable overly sexualised way. Case in point: Pyra and Tsuki. They made me uncomfortable sometimes, but most of the time I just laughed it of. I've seen worse in JRPGs.
About the story: it isn't anything special tbh. In the latter half some interesting things come up. But most of the time I found it quite cheesy and uninspired. The story didn't really grip me and thus I ignored it most of the time.
