Secret Mission ~Sennyuu Sousakan wa Zettai ni Makenai!~ (2023)
I'll provide a review based on the information available. The title you've provided seems to reference an anime or manga series, specifically "Secret Mission: The Absolutely Greatest Infiltrating Investigator." Without specific details on the content, I'll offer a general review structure that could apply to various media:
If you are a fan of crime thrillers with a dash of comedy and a protagonist who is frustratingly competent, this is a hidden gem you shouldn't miss.
At its heart, the story follows a elite undercover agent—often a disgraced or rogue operative working outside official channels—tasked with infiltrating a seemingly impenetrable target: a crime syndicate, a corrupt corporation, or a hostile nation’s black site. The twist lies in the suffix: “zettai ni makenai” (絶対に負けない).
Unlike traditional spy dramas (think John le Carré or Zero Dark Thirty) where the hero treads a knife-edge of paranoia and potential failure, this protagonist operates with plot armor as a narrative promise. The tension isn’t if they will succeed, but how they will dismantle the enemy while maintaining their cover, seducing targets, and outwitting rivals.
Original Title: Secret Mission: Sennyuu Sousakan wa Zettai ni Makenai
The rain in District 9 didn’t wash things clean; it just made the grime slicker.
Renjiro sat in the corner booth of the izakaya, nursing a glass of cheap whiskey that he hadn't taken a sip of in two hours. To the world, he was "Kuro," a stoic fixer for the Koga Syndicate. He had the tattoos (fake, painted on daily), the scowl (practiced in the mirror), and the rap sheet (fabricated by the agency).
But inside, Renjiro was fraying. He was an infiltration investigator—a sennyuu sousakan—three years deep into a mission that was only supposed to last six months.
His target wasn't the boss, Koga. It was the "Ledger of Echoes," a digital blacklist used to blackmail city officials. But to get it, he had to become the monster he hunted.
Tonight was the night. The plan was simple: Koga trusted him enough to bring him to the vault. His partner, a rookie analyst named Tsumugi, was parked three blocks away in a surveillance van. The extraction was green-lit.
Beep.
The earpiece hidden deep within his auditory canal crackled. It was Tsumugi. Her voice was shaky.
"Renjiro-san... I have a red flag on the biometrics. Koga isn't in the building. And... the vault alarm isn't just off. It's been replaced with a silent trap."
Renjiro didn't flinch. His eyes stayed fixed on the door. He knew Koga was paranoid, but this felt different.
"Abort?" Tsumugi asked. "If you go in there, you might not come out."
Renjiro thought of the three years. The men he had beaten to maintain his cover. the crimes he had let happen to stay "loyal." If he aborted now, the Ledger stayed with Koga. The city rotted for another decade. The guilt of his inaction would crush him faster than any trap.
"Negative," Renjiro whispered, his lips barely moving. "The mission proceeds."
"But—"
"I absolutely will not lose," he cut her off, reciting the agency's creed not with pride, but with the grim determination of a man signing his own death warrant. "Not to Koga. Not to this life. Pull the van to the north exit. Be ready to run."
Renjiro stood up. He

It sounds like you're referencing the Japanese light novel/anime/manga series "Secret Mission: Sennyuu Sousakan wa Zettai ni Maketakunai" (Secret Mission: The Infiltrating Investigator Absolutely Won't Lose).
If we treat your phrase "…ma best" as a stylized/misspelled version of "…make a best" or "…my best," here's a creative content concept for a story or episode based on that title.
Title: Secret Mission – The Infiltrating Investigator Absolutely Does Her Best
Logline:
A rookie undercover agent, code-named "Miyabi," is assigned to infiltrate a high-end casino owned by a mysterious crime syndicate. Her mission: find evidence of money laundering in 72 hours. But her cover identity — a clumsy heiress — keeps attracting the attention of the syndicate's charming but dangerously sharp leader. She swears she'll absolutely do her best, even if it means bluffing her way through high-stakes poker, seduction lessons from a spy manual written in the 80s, and accidentally befriending the enemy's cat.
Opening Scene (light novel style):
"An infiltrator’s best weapon is invisibility. That’s what they taught me at the Academy. But here I am, wearing a glittering evening gown that weighs more than my survival kit, spilling champagne on a crime boss’s shoes. My earpiece crackles: 'Miyabi, stay professional.' Professional? Sir, I just called a yakuza lieutenant 'cute' by accident. This is my absolute best."
Key Content Beats:
Closing tagline:
"Mission complete? Not quite. The cat is now following me home. And Ren just sent roses to my safehouse address. Next time, I'll do even better — that's a promise."
If you meant something else by "ma best," let me know and I'll adjust the tone (maybe it's a meme, song lyric, or inside joke). Otherwise, this could work as a chapter one summary or a fanfic prompt.
