When Edgeworth learns that his friend's son has been kidnapped, he goes to the theme park Gatewater Land to deliver the ransom and almost becomes a victim himself. He's rescued by Kay Faraday, self proclaimed thief, and together they battle Interpol for the rights to chase down the criminals responsible.
After seven years the Yatagarasu has returned, but why now, and what is he after? Edgeworth and all his allies come together to combat an international criminal, with not one murder but two to solve before the night is over. All five cases lead into this action packed, world-revolving finale.
