In Madoka x Homura fanfiction, the power dynamics between them can be an interesting aspect. Madoka, as a very powerful magical girl, and Homura, with her time - looping abilities, have a unique relationship. Fanfiction could play with how they use their powers in relation to each other. Maybe in a fan - created scenario, they combine their powers to save a new threat that wasn't in the original series.
I think there are several, but the exact number might change as new ones could be released. You might want to check reliable manga databases or official sources for the most accurate count.
If you are in certain regions, local streaming services might have the rights to air 'puella magi madoka magica side story'. It's also possible that some DVD or Blu - ray sets come with digital codes that allow you to watch it on specific platforms. So, keep an eye out for such offers as well.
One popular trope is the 'time - loop fix - it' where Homura uses her time - looping abilities to try and create a perfect situation for Madoka. This often involves Homura going through multiple loops, each time learning more about Madoka and how to protect her better.
Another theme is time - related. Since Homura has the ability to manipulate time in the show, many fanfictions play with this concept in relation to her relationship with Madoka. For example, stories might involve Homura going back in time to save Madoka in different ways or dealing with the consequences of her time - traveling on their relationship.
