To preserve a fragile ceasefire between the rival nations of Westalis and Ostania, top Westalian intelligence operative Twilight is assigned Operation Strix. His objective requires penetrating the insular political social circle surrounding Donovan Desmond, the reclusive leader of Ostania's National Unity Party. Because Desmond only appears at private events held at the prestigious Eden Academy, Twilight must construct a plausible domestic life within seven days: acquire a spouse, enroll a child, and maintain total cover as mild-mannered psychiatrist Loid Forger.

At a run-down orphanage, he selects Anya, an escaped laboratory test subject capable of reading human minds. To fulfill the academy's strict two-parent household mandate, Loid arranges a mutually beneficial marriage of convenience with Yor Briar, an unassuming Berlint city hall clerk who operates by night as the lethal underground assassin Thorn Princess. Completing the household is Bond, a rescue dog endowed with precognitive clairvoyance.

While Loid and Yor keep their dangerous professions hidden from each other, Anya's telepathy makes her the only family member aware of everyone's secret identity. What starts as a calculated sham household turns into high-stakes espionage balanced against school exams, social rivalries with Damian Desmond, counterintelligence threats from the State Security Service, and the genuine emotional pull of found family.

What to Expect

The narrative operates on deliberate alternating pacing, oscillating between lighthearted domestic slice-of-life comedy and lethal geopolitical stakes. Major canonical storylines escalate tactical tension significantly, including the high-seas combat of the Cruise Adventure Arc, the intense school bus hostage standoff during the Red Circus Crisis, and the ruthless urban espionage of the Mole Hunt Arc. Dramatic tension relies on dramatic irony, where Anya's telepathic deductions avert catastrophe just as Loid's clinical calculations and Yor's superhuman martial lethality clash with State Security Service inquisitions.

For readers transitioning from the anime, Season 1 and Season 2 covered the manga up to Mission 59, while Season 3 concluded the adaptation through Mission 87. To continue the ongoing canon storyline immediately following the events of the anime, pick up reading directly at Chapter 88.
