If you typed "goblins cave" and meant that gritty little series about dungeon raiding, chances are you meant 'Goblin Slayer' (or its movie 'Goblin Slayer: Goblin's Crown'), so I’ll cover those and the common regional spots where I’ve found them. Titles and rights move around a lot, but here’s the rundown I use whenever I want to rewatch or introduce someone to the series.
Crunchyroll has been the most consistent place globally for the TV show — they often carry the subtitled simulcast and sometimes the dubbed streams depending on region. In the United States you’ll historically also find it on Hulu (they carried the simuldub at one point). Physical and digital purchases (like on Amazon Prime Video, iTunes/Apple TV, and Google Play) are reliable if you want to own episodes or the movie; those storefronts vary by country but are usually available for sale or rent.
For certain Asian markets, official YouTube channels (Muse Asia, Ani-One, or regional partners) or streaming platforms like Bilibili and iQIYI have hosted episodes with proper licensing. HiDive sometimes picks up titles for catalog streaming, and Netflix occasionally licenses anime for specific countries — so it’s worth checking in your region. A handy tip I use: run a quick check on JustWatch or Reelgood to see which legal services currently have the show in your country. Avoid shady streams; aside from being illegal, the quality and subtitles are usually awful. Personally, I love watching the anime on a legit platform with good subs because the sound design and score really pop — makes the whole dark fantasy vibe hit harder.
