High school student Saya Toma, portrayed by Erika Toda, experienced a tragic loss when her parents and younger brother perished in a plane crash. Detective Akio Kondo, played by Yu Tokui, approached her with a startling revelation: her family might have been victims of individuals possessing “spec.” This was Saya’s first encounter with the concept of “spec.” Fast forward six years, and Saya, unable to shake off the detective’s words, chooses to pursue a career in law enforcement. After undergoing FBI training in the United States, she returns to Japan and is tasked with handling cold cases at the Public Security Bureau. Meanwhile, due to the machinations of Satoshi Chii, portrayed by Yuu Shirota, Juichi Ninomae, played by Ryunosuke Kamiki, mistakenly views Saya as the enemy responsible for his parents’ demise and seeks to drive her to desperation. Satoshi Chii’s plot has also led Saya and Juichi to forget their sibling bond, setting them on a collision course. In the midst of this turmoil, a girl named Maho Ueno, played by Umika Kawashima, becomes entangled in their conflict. To safeguard Maho, Saya Toma resorts to using “spec.”
