Hello, hate to be the bearer of bad news, but it seems like it's only available in JP currently. I tried looking for sites that might have the manga, but there's nothing since it seems new. I don't think anyone picked it up yet, either. Sorry about that. Look through these links for snippets and info about the manga.
