The group is tasked on a covert mission to rescue Japanese conglomerate president Youzou Kaburagi from the hands of a small Chinese military faction led by Zongwu Liu. Even though the four spies had a run in with three decoys the previous night, Yukina Sonogi deduces that Kaburagi is held captive at a fort near a riverbank east of Nanjing. Sakurai informs them that Zongwu kidnapped Kaburagi to use as a collateral for obtaining weapons and ransom money to attack the Kuomintang. While Yukina stays hidden with Natsume Kagiya in the forest, Aoi Miyoshi and Kazura Iha enter the fort at night disguising themselves as soldiers, as they confront Kaburagi for using his captivity as a business offer. They are found out after knocking the president unconscious. Aoi later convinces Kazura to use his ability of teleportation to make their escape outside the fort. It turns out that Kaburagi signed a document to permit a shipment of weapons to the allies as well as the enemies.

Sakurai requests the group to investigate a Jewish Russian violinist named Sergei Krainev, who the Kwantung Army suspects is a foreign spy who has been leaking out classified military information to an unknown benefactor. Yukina is told privately by Sakurai that her older brother Isao Takachiho had disappeared to Manchuria after the death of her father. Aoi and Yukina sees no reason as to why or how Krainev could be a spy, after having met with him personally. While Krainev begins his performance at the town hall, Aoi and Yukina realize that the fast section of his piece is a coded message that will be broadcast by radio. Even though they cut off the power supply of the town hall in time, Krainev continues to play for the love of his music.
