Secret Mission - Undercover Agents Never Back Down!

Narcotics Enforcement Agent Riko Ikazuchi is assigned to an undercover operation where she and her junior partner, Keiji Noma, pose as a newlywed couple living in an apartment that doubles as a criminal hideout. To maintain their cover they have to act like lovers, but silence at night makes the gang suspicious. When the criminals note the lack of intimacy, Noma takes matters into his own hands and begins touching Riko to sell the ruse. That choice creates a tight, awkward atmosphere where professional duty, personal boundaries, and discomfort collide, and each episode balances tension, dark humor, and the strain of pretending to be something they are not without revealing how it all ends.

The series premiered in 2023, created by mothicaw and Saburou Miura, and is presented as an animated TV show. Voice leads include Sahomi Koyama as Riko Ikazuchi and Jun Osuka as Keiji Noma, credited for bringing nuance to the uneasy partnership.

Critical and audience responses are mixed, reflected in a 6.08/10 rating from a small sample of votes. Reviewers noted the show’s willingness to test tone and to put consent and power imbalance in focus, which divided viewers. Some praised the character work and awkward comedy, while others criticized how intimate scenes are framed within an undercover scenario.

The series has generated quiet online discussion among niche anime fans and forums that debate its handling of adult themes and undercover ethics. While it hasn’t reached mainstream anime conversation, clips and character interactions have been shared by a modest fanbase, and voice performances are often highlighted in fan threads.

As far as major industry recognition, there are no widely reported awards or mainstream nominations for the show. It appears to have found visibility through word of mouth and niche community interest rather than through festival attention or televised awards.
