Kumakichi
A male bear and Usami-chan's classmate. He's basically the go-to suspect whenever Usami-chan's solving a case—and honestly, he's usually guilty. Fans have noted that his repeated involvement in the mysteries drives a lot of the story's humor, making him less of a typical antagonist and more of a running gag that keeps the plot moving.
