Danger and corruption infect the world like a parasite gnawing at its insides, something Dr. Tian Ming, a world-renowned researcher, is all too familiar with. Tian knows the man standing before him wielding a gun is dangerous—yet his curiosity and desire are piqued. Learning that the man is an ex-yakuza with more at stake than money or power, Tian agrees to follow him on his extreme mission.
Time is short for former yakuza Ikeda Ryusuke, and he needs answers. The enemy infected his sworn brother with a life-threatening, genetically-modified parasite, forcing Ikeda to desert his clan. His search for a cure leads him to Tian. But the enemy is closing in, and they’re running out of time.
