@Insignificant: Looks like Uran herself decided that she didn't want to continue after the first volume was released. Appearantly there were disagreements with the publishers.
The author themselves asked for the manga to end, it wasn't axed. So basically she just got bored of it, and just wants to go back to writing loli smut.
So much potential but the author basically either lost passion or pussy out to do another series. Not surprised there's no sex scene or orgy scene. Such a waste.
