The Plot:Narcotics agents Riko Ikazuchi and her junior partner Keiji Noma are deep undercover, posing as newlyweds in an apartment complex that doubles as a criminal hideout. When the neighbors (the criminals!) get suspicious because the "couple" is too quiet at night, Noma and Riko have to get creative—and intimate—to prove their love is real and keep their mission alive. Quick Stats: Type: ONA / Anime Short (approx. 7 minutes per episode). Studio: Rabbit Gate. Episodes: 8 episodes (Aired Oct–Dec 2023). Vibe: High-stakes action meets intense romance/ecchi.
Why people are talking about it:It’s an AnimeFesta title, meaning it comes in two versions: a censored TV-friendly cut and a more explicit premium version for adult audiences. It’s a wild ride that balances the tension of a police investigation with the awkwardness (and heat) of a fake-marriage trope pushed to the limit.

Ren Akasaka is the top investigator for the Metropolitan Security Bureau. Known for his "ice doll" persona, he never fails a mission. His new assignment? Go undercover as a personal assistant to the CEO of a suspicious tech conglomerate, Misaki Toujou, to uncover evidence of illegal data trading.
The catch? To get the job, he has to pose as her fake fiancé. The Investigation 📂 Day 1: The Entry
Ren enters the Toujou estate. He expects a high-stakes interrogation. Instead, he finds Misaki buried under a mountain of plushies, working three monitors at once. The Mission: Bug her office. Sennyuu Sousakan wa Zettai ni Makenai
The Reality: She asks him to "test" a new VR headset. It's a cat-petting simulator. 📂 Day 14: The Close Call
While searching her private safe at midnight, the lights flick on. Misaki is standing there in her pajamas, holding a glass of milk. Ren freezes, his lock-picking tools hidden behind his back. "" she asks sleepily.
She hands him a chocolate bar and tells him he works too hard. The Turning Point
During a high-society gala, a rival corporate spy attempts to kidnap Misaki. Ren’s instincts kick in. He abandons his "clumsy assistant" persona and neutralizes three armed men in seconds.
As they flee to a safe house, the truth comes out. Misaki knew who he was from the start. She didn’t hire him for his typing skills; she hired him because she knew the Security Bureau would send their best protector if she leaked just enough "suspicious" data. 📍 The Conclusion
The mission is technically a failure—there was no illegal data trading, only a lonely CEO looking for a bodyguard she could trust. However, the Bureau classifies it as a "long-term observation." The new status quo: Mission: Ongoing. Cover: Still the fiancé.
Result: Ren is no longer an "ice doll." He’s a man who actually enjoys testing cat simulators.

Some adult manga use a title like "Zettai ni Ma ni Makenai" (絶対に魔に負けない – never lose to evil). But if "ma work" is actually "maou" (demon lord) or "ma no shigoto" (demon's work), then the series might be about an investigator who resists demonic temptation.
