The manga (which ICv2 caught wind of last year; see "Confessions Of A Comic Book Guy - Heart, Humor, Hope, Heroics, And Optimism") has been running monthly in the Japanese shonen magazine Champion Red. In the series, a Japanese boy comes to Gotham City, where he tries to find out what happened to his scientist parents, who died in a factory explosion. The factory was owned by Lex Luthor, who has teamed up with the Joker, and Batman calls in the Justice League to help.
