I had used the chat gpt incorrectly in my previous fanfictions. I had always written chapters in advance and then had the AI write them in readable English. It was recently explained to me that the AI works better differently. I'm now testing the fanfiction. If it works as described, I can create the story more easily and with less effort, while also allowing the AI to create entire chapters herself (if I like it, I'll leave it in).
I'm currently watching the original anime. I only saw the first season in 2018 and then stopped watching. I'm now on season 3 and trying to finish it. The world has potential for fanfiction.
