It's actually kind of funny because I also create the story before the characters, but I only just realized it
Sometimes I create a story around a pre-made character, but it is SO much easier to do it the other way
This will help if I ever get stuck on a short story.
There are several interesting events in the Naruto series that are told but not shown. So I thought of making short stories for those events to show what might have happened. And also there are several minor characters, some only given names in the databooks, which would make for an interesting main character to do some stories about.
