Let's start with the definition of the word fandom. Fandom is a group of people who have their idol, their favorite movie and who constantly gather and communicate.
I found a lot of fans of this series on the Internet. Some of them have created a website specifically for this series.
The site presents all the characters of the series. If you click on one of them, you can see all the information about their role in the series.
In addition, on the site you can find separate categories for the actions of the series and the signs or symbols that were present in it.
Instead of the Internet, I found a lot of groups on social networks created by fans.
There are also some meetings where fans gather. Sometimes even with the main characters of the series. Moreover, there are many videos of parodies of this series.
