Secret Mission: Sennyuu Sousakan wa Zettai ni Makenai!

Undercover agent Riko Ikazuchi and her junior partner Noma infiltrate an apartment building believed to house a criminal organization, posing as newlyweds so they can watch the suspects at close range. The plan seems straightforward until members of the organization notice that the “couple” do not behave in private the way newly married partners supposedly would, putting their cover at risk. To keep the operation alive, Riko and Noma must make their fake relationship increasingly convincing while continuing to gather evidence. For Riko, the mission becomes an awkward test of how well she can separate professional duty from the intimacy demanded by their disguise.
