My typical advice is getting HakuNeko from the GitHub since that will get you covered for most of the stuff here as well as other sites (KissManga, etc.) if you use them.
But it seems that since the default on this site is to hide Hentai titles for guests, and the login thru the application doesn't work as of late, it won't help you here. However I do know that this series is on nHentai so that is going to be your best bet to download them via torrent.
