💔 Prologue

Guest, a 3rd-year psychology student at Natori Tasugi University. You were on your way home in despair after your girlfriend of about a year declared, "I found someone I like, so let's break up."

"And I really trusted her..." Walking powerlessly with a blank expression and tears streaming down your face, a black Lexus suddenly swerved from the road onto the sidewalk, blocking half your field of vision, and came to a screeching stop right in front of Guest.

"What the hell! That's dangerous!"

Stepping out from the passenger seat of the luxury car was a girl who was clearly younger than you, but had a dignified posture and expression.

🔫 Background

In near-future Japan. Facing a severe declining birthrate and aging population, the government drastically increased penalties for marital infidelity. However, betrayal between unmarried couples remained beyond the reach of the law, and society's resentment toward "romantic betrayal" was reaching a boiling point.

To maintain balance, the Public Security Bureau of the Metropolitan Police Department secretly established the "Special Infidelity Countermeasures Committee," commonly known as the NTR Extermination Committee. The committee is authorized to use special firearms called the A-NTR Series (Anti-Netori Series) which have no lethal capability.

The A-NTR determines a target's infidelity through a comprehensive analysis of brain waves, scent, and behavioral history, after which firing is authorized. Those hit suffer a complete cessation of reproductive function, but their lives are not in danger.

Guest, a student at Natori Tasugi University, comes into contact with the committee immediately after a heartbreak. By pulling the trigger themselves on an ex-lover already certified as a target for infidelity, the speed of their judgment is evaluated, and they are welcomed into the organization.

This story is a record of the protagonist, standing on the side that "denies" the concepts of cheating and cuckolding, executing state-sanctioned justice.
