Yes 57 that's the one, the next untranslated one, I had the number wrong
Right, so, here's the thing: I don't know if chapter 57 has been released in Japan. I mentioned before (in answer to another of your questions) that Futaribeya is published online these days, and even gave you the address of the website. Since I suspect that, unlike Sakurako, you don't have near photographic memory, I'll tell you again: Comic Boost is the place where the new chapters of this manga are uploaded. If you want to know whether 57 is out or not, you should go there; but it's in Japanese, and you'd probably have to pay to find out.
Alternatively, you could ask the scanlators, who probably have better information on the subject than anyone in this forum. This is their address:

Just leave your questions there; if you're lucky, they will reply and tell you what you want to know.
