i use Jdownloader for 2 years now
first time i used because people on other anime forums were trying to protect their links from being reported and deleted by making a .DLC container (which obviously contains links to download)
.dlc itself is small as 20 kb but you can download whole series with just a small file !
like encrypted .txt file with links
go for it ! its awesome
and with latest updates it can auto-grab links if you just press ctrl+C ;0
