Sonarr and radarr aren’t going to do what you claim without a Usenet client to do the actual downloading. So on top of your *arrs you also have to pick a quality indexer, find and pay for a Usenet provider, and set up your download client. And preferably use a nicer frontend for finding the content a la Overseerr or Ombi. And probably Bazarr to get subtitles for all the anime/foreign language content. Also good luck getting good, consistent releases automatically without some serious dedication to setting up your quality profiles.
