In the neon streets of near-future Tokyo, sixteen-year-old twins Touka and Yuuto Kimizuki live a double life. To their classmates, they are typical high school students. However, the twins hide a lethal secret. They are elite secret agents for the Public Security Intelligence Agency (PSIA). Touka and Yuuto are prodigies who mastered the art of elimination before they even finished middle school.
In The Mind Control Assassins, the stakes reach a breaking point. The PSIA assigns the siblings to their most dangerous mission yet. Alongside their father, they must protect the final survivor of the Transhuman Development Project: Dr. Nobuhiko Hayama. Currently, someone is systematically erasing every scientist involved in the project. As the last researcher left alive, Dr. Hayama is the next target on the hit list.
The twins soon realize that protecting the doctor requires more than just martial skill. Their first encounter with Dr. Hayama unearths a dark conspiracy. Consequently, they begin to question their understanding of human agency. Behind the “Mind Control” experiments lies a fusion of technology and biology. This dark science threatens to reshape the future of warfare forever.
