In 1949, Japanese-American comic book artist Kevin Yamagata achieves major commercial success in the United States with his detective comic strip featuring an anthropomorphic detective named Billy Bat. When an American detective offhandedly reveals that an identical character design already exists in Japan, a horrified Kevin travels to Tokyo during the Allied occupation to secure permission from the original creator, desperate to avoid unintentional plagiarism. However, his inquiry drags him directly into a dark web of Cold War espionage, real-world political assassinations, and unsolved historical murders.

As Kevin investigates the origin of the emblem, he discovers that Billy Bat is not merely a cartoon character or a fictional construct. Instead, the bat is an ancient, supernatural force that has appeared to prophets, emperors, and visionaries throughout recorded human history—from ancient Mesopotamia and Sengoku-era Japan to Leonardo da Vinci and modern world leaders. Divided between two opposing manifestations—the black bat and the white bat—the entity imparts prophecies that shape the rise and fall of civilizations, pulling humanity toward either salvation or catastrophic ruin.

What to Expect

Billy Bat features masterclass narrative weaving across multiple centuries, blending factual mid-century historical events like the Shimoyama incident and the JFK assassination with chilling supernatural prophecy. Readers can expect deliberate psychological tension, 4D chess geopolitical maneuvers, non-linear timelines, and shifting generational protagonists rather than conventional martial battles. Urasawa's meticulous pacing constructs an inescapable mystery where every piece of art holds apocalyptic consequences.
