Upon returning from feudal Japan to present day, Batman discovers that historical changes have caused an upheaval in the present. Japan has disappeared from the world map and a huge island called "Hinomoto" appears in the sky over Gotham. Batman and his friends head for Hinomoto to seek the cause of the upheaval. There they find a world where the yakuza rule and where there is no honor. Everything comes to a head when Batman and his friends battle Superman and the Justice League, now members of the yakuza, to return the world back to normal.
