In 1949 California, Japanese-American comic book artist Kevin Yamagata achieves nationwide success with his detective comic series starring Billy Bat, an anthropomorphic bat sleuth. When a visiting detective reveals that an identical bat character was drawn in postwar Japan years earlier, Kevin travels to Allied-occupied Tokyo to secure permission from the original illustrator, fearing he unconsciously plagiarized the figure during his military service. Instead of an artistic dispute, Kevin stumbles into the bloody aftermath of the Shimoyama Incident, finding himself entangled in murders executed by covert military intelligence agencies.

The investigation uncovers an ancient prophecy tied to a mysterious bat figure that has guided, manipulated, and recorded human history across thousands of years. From feudal ninja conflicts in Iga to the crucifixion of Jesus, the assassination of John F. Kennedy in Dallas, and the Apollo moon landing, the bat appears before select artists and visionaries. As Kevin discovers that drawings of the bat alter or foretell geopolitical events, rival syndicates headed by corporate magnate Chuck Culkin weaponize the symbol for global media dominance and social control, setting off a generational race to decipher the true intentions of the white and black bat entities.

What to Expect

Billy Bat blends meticulous real-world history with high-stakes psychological intrigue across a non-linear timeline. Rather than brute-force combat, tension is built on forensic investigation, Cold War espionage, artistic integrity, and philosophical debates over free will versus prophetic fatalism. The narrative shifts fluidly across decades, following different protagonists such as Kevin Yamagata and Kevin Goodman, while exposing the mechanics of media manipulation, historical cover-ups, and corporate monopolization.
