Is Overlord Season 3 Just Side Stories?

Yes. They are. They fill in gaps in the main story and give more context to different aspects of the 'Overlord' world.

It depends on your interest. If you're really into the 'Overlord' universe and want to know more about the secondary characters or the backstories of certain events, then the side stories are great. But if you're only interested in the main plotline, you might not find them as essential. However, they do add more flavor to the whole story.

It's a mix. There are real - world problems that can be considered 'dark side' elements, such as the commercial aspects that can make it seem less magical for some. But the spookier stories, like the supposed hauntings, are more likely to be a combination of rumor, legend, and the power of suggestion. People come to Disney World expecting magic, and sometimes that can lead to seeing things that may not be there or exaggerating normal events into something more mysterious.

Overlord Season 4's placement in the manga isn't straightforward. It depends on how the production team chose to adapt and sequence the storylines. Sometimes they might compress or expand certain parts for the anime.
