Billy Bat(2008)

Billy Bat

It’s 1949 Los Angeles, and Kevin Yamagata, a Japanese American comic book author, is drawing his bestselling character, Billy Bat: a quick-witted detective who is, unsurprisingly, a cartoon bat. Everything is going well for Kevin until he discovers an unfortunate truth: He may have unintentionally plagiarized his beloved character from a drawing he once saw in Japan. Devastated by the news, Kevin returns to war-torn Japan to find the drawing’s original artist . . . but the character’s origins turn out to be far older and more perplexing than he had ever imagined.
