Secret Mission Sennyuu Sousakan Wa Zettai Ni «Pro · 2027»

The finale of the first major arc sees Haru holding a gun to her handler’s head, screaming, "I will absolutely not let you hurt them!"—a direct inversion of her original orders.

Title: Secret Mission: Sennyuu Sousakan wa Zettai ni... (Secret Mission: The Undercover Investigator Absolutely Will Not...)
Genre: Adult Visual Novel / Eroge / Espionage Thriller
Review:
Secret Mission: Sennyuu Sousakan wa Zettai ni is a title that plays heavily on the popular "absolute refusal" trope seen in modern eroge, but wrapped in a classic espionage setting. The premise follows an elite female investigator who goes undercover in a dangerous criminal organization. The hook, as suggested by the title, is her internal vow: "I will absolutely not fall" — whether that means not getting caught, not betraying her mission, or not succumbing to the enemy's seductive traps. The line between operative and target blurs completely

Who Is This For?
Who Should Avoid?
Final Verdict: Secret Mission: Sennyuu Sousakan wa Zettai ni is a competent, if formulaic, entry in the adult visual novel genre. Its strengths lie in atmospheric tension and effective character art, but it doesn't break new ground narratively. It delivers exactly what the title promises: a story about an investigator who declares she will absolutely not fail or fall, then puts her through every conceivable trial to make her break that vow.
Rating: 7/10 — Solid for genre fans; forgettable for general VN enthusiasts. Weaknesses / Considerations:
She checked the imprint on her wrist — three bruises from yesterday’s training, a map of the route under translucent skin. The dossier called it Location C; she called it a schedule to beat. Objective: retrieve the ledger, leave no trace. Time window: twenty minutes between the north guard's cigarette and the service elevator’s hourly maintenance pause. She moved like someone who had practiced refusal until it became a reflex — not brave, not reckless; absolute.
She slid the heel pads into place and folded the micro-torch into her sleeve. On paper, there were contingencies for every lock and a photograph of the corridor in noon light; in practice, she would follow the rhythm of footsteps. Tip: memorize three distinctive sounds in any room — a clock tick, a humming vent, the scrape of a chair leg — and use them to keep count.
For those reading the manga adaptation illustrated by Ryo Tachibana, the visual storytelling is crucial. Tachibana uses a technique called "negative space infiltration." In action scenes, panels are full of frantic motion lines. But during Haru’s moments of crisis—when she is deciding whether to break the zettai ni rule—the panels become stark white, with only Haru’s face and a single, dripping water drop or a falling leaf. It forces the reader to sit in her silence.
Furthermore, the use of "reflection panels" is masterful. Haru is often drawn looking into windows, mirrors, or polished floors. But the reflection never matches her facial expression. It’s a visual cue that her inner self is no longer aligned with the mask she wears.
The central question of Secret Mission Sennyuu Sousakan wa Zettai ni is: Can you serve a cause without losing yourself? The series answers brutally: no. Himura’s "absolutely not" rules are not for the mission's success; they are for his own survival as a person. Every time he breaks a rule (saving a child, comforting a colleague, telling a half-truth to protect an innocent), he makes himself more human—and more vulnerable to being killed or, worse, "turned."
