Season 1

Nagare, a part-time worker who has decided not to lie for "a certain reason," is secretly summoned by the Ministry of Defense. All seven of the people gathered, including Sae, an office worker, and Tuta, a university student, possess "certain abilities."

While Nagare and the others agree to become reserve heroes, Sae only accepts provisionally, and when Fujiwara calls out to her, she ignores him. For "certain reasons," Sae avoids interacting with people, and is an outsider both at work and in the reserves.

"Mizuno-san! Were you a criminal...?" asks Mizuno, a university researcher, who is then interrogated by Madozumi, an employee of the Ministry of Defense. He also learns from Defense Minister Kurokawa that he has a criminal record.
