In a dystopian future where Tokyo has become a crime-ridden wasteland, the Tokyo Private Police (TPP) are hired by the wealthy to maintain order. Noriko Ibuki, a determined officer, is assigned to the Mobile Police unit, where she must navigate a chaotic work environment characterized by poorly maintained mecha and a highly sexualized culture among her colleagues. Despite the dysfunction and her own personal struggles, Noriko resolves to persevere in her training and fulfill her duty to protect the city.
After completing their combat training, Noriko and Kayoko are deployed on their first real mission to apprehend criminals in Shinjuku, leaving the mecha-obsessed Yasuo behind. Following the successful operation, Noriko and Yasuo bond over their reports and discover a mutual romantic attraction, leading to an intimate encounter. Their newfound passion is quickly put to the test when an emergency call summons the Mobile Police Force to handle a riot in the Ginza slums.
