Matsumi Kanata, a brilliant but antisocial Tokyo police detective, is tasked with a secret mission: infiltrate Tsubakino University of the Arts to identify the culprit behind a series of drone bombings. Because the institution was recently an all-women's university and remains predominantly female, Kanata is forced to disguise himself as a woman to blend in. During his undercover assignment, he crosses paths with three distinct students: Haruna, the vocal department's star performer; Misuzu, who grows hostile after losing a musical role to Kanata; and Riko, who discovers his true identity but becomes his investigative partner. As Kanata immerses himself in student life, he gets so swept up in rehearsals for the upcoming musical production that he begins neglecting his mission. Everything comes to a head on the day of the performance when a sudden dramatic turn forces Kanata to balance saving the musical with finally uncovering the bomber's true identity.
