ビリーバット Billy Bat [Birii Batto] #1

This Japanese-language volume collects the opening chapters of Billy Bat, the manga series by Naoki Urasawa and Takashi Nagasaki. The story follows a Japanese-American comic artist in 1940s New York who discovers that his creation, a bat detective named Billy Bat, has been drawn before—a revelation that ties him to a centuries-old conspiracy. Published by Kōdansha, this first volume sets up the series' blend of historical fiction, mystery, and metafictional intrigue.
