Zen Seizaki

Zen Seizaki was once a standout prosecutor within Tokyo's Special Investigation Department, until a probe into a pharmaceutical corporation's illicit dealings dragged him into a vast conspiracy centered around a so-called 'Suicide Act.' When his trusted colleague was murdered by the enigmatic and manipulative Ai Magase—a woman who treats human lives as mere playthings—Seizaki made the pivotal decision to join the FBI as a Special Investigative Agent, extending his pursuit across international borders. His relentless chase forces him to constantly wrestle with the boundaries of law and morality, confronting the ultimate question of what truly defines good and evil.
