I couldn't find a torrent for collection of all scanlations for Last Game. So I made one by scraping from mangarock. As far as I know no single group did the whole translation and it doesn't have an official release, so these are the best quality I could find.
Note: It isn't organized by chapters in the cbz file. If you want me to upload a chapter organized version leave a comment below
Another note: I could have done a mistake. Some pages are probably out of order. You can find chapters organized in folders if you rename the extension to zip/rar/7z and unzip it.
