But 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 that's not all, the Justice League, a team of the World's Greatest Super Heroes, has disappeared."
