As of now there is 11 chapters in English (15 including anime adaptation announcement in raw). This manga is worth a read, I can't wait for the anime adaptation of this and see if this gets the popularity it deserves, the artwork is really clean and the characters (even though not really gone into) are built great and you can understand their relations with each other. I can't give a full review because it has not finished yet but it is great once you get into it and worth a try. But overall I see potential it it for all it is.
