Bungo Stray Dogs has a colorful cast of characters. Nearly everyone has a name and power based on a well-known author and their work. Despite this similarity, the characters themselves are different people. They look and act more like anime characters than their namesakes; this makes them more like inspirations than counterparts. The anime characters have no obligation to share anything with their namesakes beyond their names, and even that rule gets bent sometimes. However, there are times when other things about these two groups line up—like the day they were born.

There are plenty of ways to get to know the Bungo Stray Dogs cast besides their roles in the anime and their birthdays. Plenty of information about them has been given out in one form or another beyond what's explicitly stated in the main story. This includes things like their heights and ages. Their zodiac signs can also be determined based on their birthdays. In the grand scheme of Bungo Stray Dogs' narrative, this information is unnecessary for understanding what's going on. However, getting to know the characters like this makes them feel more like real people, even if they aren't like the people they were based on. It gives them more of an identity for fans to relate to.
