Batman Ninja vs. Yakuza League

In a world where Japan has disappeared and a parallel universe now hangs over Gotham City, the Batman family must band together to save their home from an invasion of yakuza-style criminals led by a twisted version of the Justice League. With the Yakuza League wreaking havoc above Gotham, the Dark Knight and his allies embark on a perilous journey through the skies to uncover the truth behind this interdimensional rift. Along the way, they encounter alternate versions of their heroes, including Zeshika, Asha, Bari, Daiana, and even Ra's al Ghul, as they fight to protect Earth from destruction.
