It seems you are referring to a title that combines Japanese and English: "Secret Mission: Sennyuu Sousakan wa Zettai ni New" (possibly meaning "Secret Mission: The Infiltrating Investigator is Absolutely New / Must Not [something]"). This does not correspond to a known official anime, manga, game, or military operation.
Based on the phrasing, this appears to be a fictional or fan-created concept — possibly from an unpublished visual novel, roleplay scenario, or doujin work. Below is a sample report written as if this were a real intelligence operation or fictional mission debrief. You can use this template for creative, academic, or parody purposes.
The Japanese term Sennyuu Sousakan (infiltrating investigator) carries specific genre weight. Unlike a standard detective or soldier, a sousakan implies a mix of judicial authority and covert observation. They aren't just spies; they are gatherers of irrefutable truth.
Most stories depict these agents as either superhuman prodigies or bumbling failures. Secret Mission rejects both. Kage operates like a seasoned jazz musician—improvisational yet deeply grounded in theory. When a rival faction’s interrogator asks, “Aren’t you new to this?” Kage’s internal monologue reveals the truth: I’ve been running operations since before you were born. But outwardly, they stammer, drop their fake ID, and apologize. The enemy laughs, lowers their guard, and is neutralized within two pages.
This is what fans are calling "Reversed Experience Isekai" —though there is no fantasy world here. The fantasy is the idea that a master can pretend to be a fool so convincingly that the entire underworld underestimates them.
If you’ve been scrolling through social media lately, you might have seen a few clips that made you stop and ask, "Wait, is this a serious spy thriller or a comedy?"
The answer, wonderfully, is both.
Today, we’re taking a closer look at the anime adaptation of "Sennyuu Sousakan wa Zettai ni Makeinai" (The Secret Mission: Undercover Agent Will Absolutely Not Lose). It’s a title that seemingly came out of nowhere to capture the attention of fans who love high-stakes espionage mixed with absurd humor.

The Evolution of Detective Fiction and the Allure of "Secret Mission: The Absolute Detectives"
Detective fiction has long been a staple of popular literature, captivating audiences with its intricate plots, clever deductions, and thrilling conclusions. From the classic tales of Sherlock Holmes to modern-day thrillers, the genre continues to evolve, incorporating new themes, styles, and technologies.

The Concept of "Secret Mission"
At its core, "Secret Mission: The Absolute Detectives" revolves around a team of elite investigators who operate outside the boundaries of conventional law enforcement. These detectives, often referred to as "absolute detectives," are tasked with solving cases that require a high degree of discretion, creativity, and bravery. By working in the shadows, they can pursue leads, gather intelligence, and execute strategies that might be impossible for traditional law enforcement agencies.

So, what makes "The Absolute Detectives" so compelling? For one, the series offers a fresh take on the traditional detective archetype. Rather than relying on a single, iconic sleuth (e.g., Sherlock Holmes or Hercule Poirot), the series features a team of investigators with diverse skill sets, backgrounds, and motivations. This ensemble approach allows for greater character development, as each detective brings their unique perspective to the table, contributing to the team's overall success.
Furthermore, "The Absolute Detectives" offers a sense of authenticity, drawing inspiration from real-world law enforcement and intelligence agencies. The series' attention to detail, from tactical operations to forensic analysis, adds a layer of credibility to the narrative, making the fantastical elements more believable and immersive.

The anime series Secret Mission: Sennyuu Sousakan wa Zettai ni Makenai! (also known as Secret Mission: Undercover Agents Never Back Down!) has become a standout entry in the AnimeFesta lineup since its release. Adapted from Mothica's adult manga Motto Aeide! Sennyū Sо̄sakan wa Sex mo Oshigoto desu, the series delivers a high-stakes blend of police procedural action and intense romantic drama. Core Premise and Plot

The series was produced by the studio Rabbit Gate, with Saburou Miura serving as the director and handle series composition. Secret Mission: Sennyuu Sousakan wa Zettai ni Makenai!
So, the phrase roughly translates to "The Secret Mission Infiltration Investigator is Absolutely New" or something similar.
Given this seems to be related to a story or game involving a detective or investigator on a secret mission, I'll create a piece of useful content related to the concept of being an investigator or detective, especially one that might be on a secret mission:
The story follows Kaburagi, a master spy working for the Commonwealth. His mission? Infiltrate an all-girls high school to protect a potential target, the young Mitsugu. To get close to her, he has to go undercover—but here’s the twist: his cover identity isn’t another student or a teacher. He is disguised as a janitor.
What makes the show so entertaining is the juxtaposition. Kaburagi is a highly trained, deadly serious agent. He approaches cleaning a window with the same intensity as disarming a bomb. But despite his best efforts to blend in, his cover is constantly at risk of being blown—not by enemy spies, but by Mitsugu, who immediately suspects that this "janitor" is up to something.

Blurb:
They say the best undercover agent is invisible—blending in so perfectly that no one ever suspects a thing.
But what if the agent has zero experience, zero backup, and zero clue?
Meet Shinjiro Tateyama—fresh out of the academy, top marks in theory, but his first field assignment is a disaster waiting to happen. His mission: infiltrate an elite international crime syndicate known only as "N.E.W."
The problem?
His handler gave him the wrong cover identity.
His contact is dead before the first meeting.
And the enemy already knows someone is coming.
Now Shinjiro has to improvise, adapt, and somehow survive while pretending he belongs there—because in this world, being "new" isn't an excuse.
It's a death sentence.
"Zettai ni new" — Absolutely new. Absolutely doomed. Or absolutely the one thing N.E.W. never expected. High Tension: The stealth mechanics are solid and
Designate Shinshi-1 for training role only. Further “new agent” missions should recruit amnesiacs or fabricated personalities to reset the “zettai ni new” condition.
