Kennedy, who was fatally shot in Dallas, Texas on November 22, 1963.   ~!When working at "Billy Land" he had a vision of the Bat asking him if he wanted to be this Country's Next Hero. The Bat ordered him to protect Kevin for the sake of mankind. Later in JFK Assassination he actually wasn't the murderer. At the time JFK was shot he was at the library building with Jackie, but in the end he accepted to become scapegoat instead.!~  (Source: Wikipedia)

The story is set in 1949 and follows Japanese-American comic book artist Kevin Yamagata as he draws the popular detective series "Billy Bat" for "Marble Comics." When he learns he may have unconsciously copied the character from an image he saw while serving in occupied Japan, he returns to Japan to get permission to use Billy Bat from its original creator. Upon arriving there, however, he becomes embroiled in a web of murder, cover-ups, and prophecy that all leads back to Billy Bat. It is soon evident, however, that the truth of Billy Bat's nature is far larger than Kevin could ever guess, spanning millennia and across the world.
