Chiro Star Project

I really like this Mahnwa, but there are only four volumes published in english and I know there are more. But it doesn't seem that they are being licensed. Does anyone know what's going on?? I've only read, like, two of the volumes but I love it...^^

>1 Taigamimi:
I hate when translated series are incomplete :(

Here is a website that has the first 5 volumes.

This website has all volumes (I think it's in English).
