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.
