Who is behind the sudden rise of a previously minor politican to the top of Judoh's underground? How are the mysterious Celestials, who watch Judoh from above, involved? And what secrets lie hidden in Daisuke's own past--and inside J's memory?

When greater evil arises, he calls on his magnificent relic of Paradigm's past, the Megadeus Big O. With Big O at his side, Roger Smith may be Paradigm's only hope of surviving in this new world without memories.
Both series have a distinctive American feel to them. The witty dialogue, the self-confident hero and baddies that seem ripped from the pages of a pulp magazine create an atmosphere not usually seen in Japanese works. The early detective-style episodes are a joy to watch, especially when you reach the second half of the series and realize everything is connected.
