Fraud, deceit, and greed. They have already changed the face of baseball in Japan, and are threatening to engulf the sport across the world.

Six seasons have passed since Casey Neal and his friend Don-o saved the game in the United States. Now Don-o is gone, and Casey is a baseball reporter who is alone and trying once again to find himself, all while immersed in a culture he doesn't understand. While he chases the story, he discovers fellow baseball fans in Japan's chief inspector Yuni Ichihara, and Diaki Matsui (a metal worker from Tokyo's industrial complex). Together they deal with such strangeness as international organized crime rings, Yōkai spirits, quantum physics, and ... well ... pickled everything.

This time the stakes are global. Can Casey's team manage to save baseball once again?
