Batman Ninja vs. Yakuza League

The Batman Family has returned to present-day Gotham City after traveling back to the warring states period and saving history from being altered in the previous film, Batman Ninja. The next day, they witness a startling event – the Japanese island has disappeared, and a giant island called “Hinomoto” appears in the sky over Gotham City. Soon, countless Yakuza descend from the sky and attack the people of Gotham City. And, the Justice League has disappeared. Detecting a strange energy reaction in the sky, Batman heads for Hinomoto to find its underlying cause. There, the Dark Knight finds a world where the Yakuza war with each other, and brutality reigns without honor or humanity. At the top of the world is the Yakuza League, a group of superpowered individuals, who look suspiciously like the Justice League. The Yakuza League is invading Gotham and, to save the city, Batman and his allies are in for the fight of their lives!
