In the real world, Tokyo’s most cosmopolitan ward: center of metropolitan power, crossroads of traffic, den of vice. But in Shinjuku, Daniel Legend, in search of his missing sister Angela, discovers the unreal city: Shinjuku, the nexus of realities, riddled with underground pathways.

In this realm where lowlife crooks and subterranean monsters spill blood alike in the shadows, three rival yakuza leaders hold control over every earthly crime in a tense triad of greed. Yet for one mobster lord, Shi, no amount of worldly gain is enough to satisfy him—and he plans an unholy scheme to seize control over all existence that merges mystcism with the visionary quantum research that was the legacy of Daniel and Angela’s father!
