In 1941, the smoke of Pearl Harbor was just beginning to rise. The flames of war swept across the South Pacific, and Japanese troops trampled through the jungles of Malaya, their ambition set on conquering all of Southeast Asia. In a world thrown into chaos, the Takeda twin brothers infiltrated enemy ranks. With their bodies as blades and their faith as a guiding light, they forged ahead into the depths of the espionage war.
The elder brother, Takeda Shinichi, joined the Japanese Army's Malaya Regiment and maneuvered through the web of power under Yamashita Tomoyuki, stealing top-secret military intelligence amid the clash of blades. The younger brother, Takeda Shinji, a doctorate in chemistry, infiltrated a secret service agency in the South Seas. With his advanced expertise, he created a clandestine chemical lab and built an underground stronghold of resistance against Japan. Both brothers were underground members of China's Red Party. Though separated by only a short distance yet worlds apart, they carried the same devotion to their country and people, each holding fast amid bloodshed and turmoil.
