Someone in my comments drop the suggestion of trying #kurotv for fire stick as an replacement for fire anime. Now it’s not as good as #fireanime but it will do 💯💫
Instructions:
For Kuro tv, Just download the app downloader and put in the code 195727 and click install. Here is step by step guide just in case. Once app is installed and if your screen is black click on the arrows in the upper hand corner.
