(Note: I assume the title refers to a comedic/romantic anime/manga premise about a “secret infiltration detective” who insists on being the best; adjust if you meant a specific existing series.)
Introduction Secret Mission: Sennyuu Sousakan wa Zettai ni Ma Best is a playful, high-energy story concept that blends action, espionage, and slice-of-life comedy. At its heart is a quirky protagonist whose overconfidence leads to hilarious mishaps, heartwarming growth, and exciting stealth sequences that keep readers hooked.
Premise The series follows a young undercover detective assigned to a city’s covert operations unit. Publicly mild-mannered, they insist they must be “absolutely the best” at infiltration. Their dedication to perfection clashes with reality: bumbling disguises, accidental reveals, and an entourage of eccentric teammates who both enable and foil missions. Each episode/chapter mixes mission-of-the-week thrills with character-driven moments that reveal why being the best matters to them.

It sounds like you are looking for information on the manga titled "Sennyuu Sousakan wa Zettai ni Makenai!" (often translated as "The Undercover Investigator Absolutely Won't Lose!" or "The Undercover Investigator Will Never Be Defeated!").
You mentioned "Secret Mission" in your request, which is likely a translation of the "Sennyuu" (Infiltration/Undercover) part of the title, and "Ma best" seems to refer to "Makenai" (Won't Lose) or simply expressing that the series is "the best."
Here is a helpful article introducing this title, why it’s worth reading, and what to expect.
Let's analyze why stories fitting the "secret mission sennyuu sousakan" mold have produced some of the most memorable arcs in recent memory.
The best undercover stories understand that infiltration is an act of psychological self-destruction. To be a great investigator, the protagonist must genuinely understand the enemy. They must laugh at their jokes, respect their skills, and sometimes even grow fond of them. This creates a rich seam of dramatic irony. The audience knows the mission’s objective, but they watch, breath held, as the investigator struggles with burgeoning loyalty.
When a story achieves "zettai ni ma best" status, it means the writer has mastered this tightrope walk. The investigator’s eventual betrayal of the villainous faction feels less like a victory and more like a tragedy. This emotional complexity is what elevates the genre above simple action fare.
Yes! The title Sennyuu Sousakan literally translates to "Infiltration Investigator." The entire plot revolves around a "Secret Mission" to uncover the truth behind the school's rumors.
