Yes. End credits are a standard part of a movie, and 'Scary Stories' follows this convention. They might not be as long or elaborate as some big - budget blockbusters, but they do exist. During the end credits, you can see the names of the people who worked on the movie, which is a great way to show appreciation for all their efforts in creating the 'Scary Stories' experience.

No one knows for certain when the JJK manga will conclude. The direction of the story and the decisions made by the author will ultimately determine the ending time.
