Storm Over Shinjuku

apan, 1999.
As methamphetamine surges back into the streets under new, foreign-backed distribution routes, Tokyo's underworld fractures. Legal pressure from the Anti-Bōryokudan Laws forces the Yakuza deeper into the shadows, where rival clans wage silent wars over control of a drug trade no longer bound by tradition.

Detective Saitō Hiroshi, chosen for a covert operation the National Police Agency refuses to acknowledge, must embed himself within the rising Yamaguchi-gumi network. His entry point:
Takeda Chūdoku, a violent, unpredictable enforcer whose drug dependence makes him both dangerous and indispensable.

To gain the syndicate's trust, Saitō must survive a street ambush, navigate shifting alliances, and immerse himself in a criminal world where violence is language and paranoia is currency. But as the gangs form unprecedented ties with foreign suppliers, Saitō discovers that the real threat may lie far beyond Tokyo's borders-and much closer to him than he realizes.

The deeper he goes, the more difficult the way back becomes.
And the line between duty and survival begins to dissolve.
