Tsuyoshi Suzuka (Eoji Suzuka), who opened a detective agency in Kujuya Town, and detective assistant Urabe Kanoko (Honoka Matsumoto) continue to work.As an assistant, Kanoko has been thinking about hoping to be able to help her husband as soon as possible.At this time, the landlord of the office asked Kanoko to find a cat.Although the cat was found successfully, Zuoma planned to use the cat as a negotiation material to see if the rent could be waived or if it could be exchanged for money. Kanoko was shocked by Zuoma's move.

In this way, the two returned to the office and found Chiyo Fujishima (Yuki Katayama).“Nothing good happens once you get involved”, and Uuma and Kanoko, who wanted to escape, hid in Wakatakeza's practice (sacrifice team).However, Zuoma was stopped by an acquaintance, and Chiyo discovered Zuoma.Chiyo ran towards the left and right horses, but collided with a man and fell down.The man left after confirming that Chiyo was not injured. Kanoko picked up the bag that Chiyo dropped.Then, in order to help Chiyo, whose clothes were messy, get dressed again, the group returned to the office.

After getting dressed, Chiyo took a keen interest in the detective agency.She opened her bag to record the appearance of the office, but found an unknown hand mirror inside.Chiyo speculated that the hand mirror might have been dropped when he hit it just now, so he offered to give it back to the man.Based on the man's attire at the time, Zuoma suggested that she go to the mason's place to find out, and asked Kanoko and Chiyo to go together.Chiyo said excitedly: The girl detective team is established!%, left the office with great enthusiasm.

Soon, Kanoko and Chiyo found a mason's shop, found out that the man's name was Toshiichi (Hashimoto Jun), and successfully returned the hand mirror to him.However, later it was discovered that there was a pickpocketing incident in the surrounding area.After hearing a woman say that a hand mirror had been stolen by a young man, and the characteristics were consistent with the hand mirror in Toshi's hand, Kanoko and Chiyo once again searched Toshi as a pickpocket.
