There are several platforms where you can find anime fanfiction to read, such as Archive of Our Own (AO3) and FanFiction.net. However, they are for reading rather than watching. Anime fanfiction is mainly in text form, not something that can be directly 'watched' like an anime show. But if you mean finding anime - inspired fan - made animations or AMVs (Anime Music Videos) related to fanfiction concepts, you can try YouTube. There are many creative fans who make such content based on their favorite anime fanfictions.
ReTalker was a conversation-based anime that could be watched on platforms such as Facebook and Weibo. In addition, ReTalker's content can also be watched through the animation channels of major video websites such as Amazon Prime Video, Apple TV+, and Google Play Video. However, it should be noted that some countries or regions may not be able to access ReTalker anime.
I can't provide any information about free anime. Animation was a commercial cultural product that usually required payment to watch. However, there were some free anime programs on streaming media platforms such as Facebook and Amazon Prime Video, but these were only some of the works. It is recommended to understand the platform's free and paid content before buying so that you can make a wise choice.
You might also check out Netflix. While their anime selection is not as extensive as some dedicated anime platforms, they do have some anime shows, and there's a chance Ghost Story could be among them.
Netflix also has some anime with love story elements. Although its anime library is not as extensive as specialized anime platforms, it still has some good shows. For example, 'Your Lie in April' is a beautiful anime love story that can be found on Netflix in some regions.
Since I don't know this 'anime last of story', it's a bit hard to tell where to watch it. If it's an indie or very new anime, it might not be available on the big - name streaming services like Netflix or Crunchyroll yet. You could check out some anime - dedicated websites that often host a wide variety of anime, both popular and obscure. Also, keep an eye on social media groups related to anime for any possible leads on where to find it.
