Batman Ninja vs. Yakuza League

“Who can face the chaos if not Batman?”

The Batman family returns to the present and finds Japan gone. In its place, a giant island called Hinomoto hangs in the sky over Gotham City, and at its peak sit the Yakuza, a crew of superpowered rulers who look a lot like the Justice League. Batman (Koichi Yamadera), Robin (Yuki Kaji) and Nightwing (Daisuke Ono) have to take back their city from people who govern without honor or humanity, and the film is a fight over who deserves the power they hold.
