ข้อมูลอนิเมะNight Raid 1931

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.

Yukina receives a letter from her missing brother, saying he wants to meet her, but overshadowing all that is the much more immediate bomb threat involving the four department stores in Shanghai known as the Big Four. The assailant lets Yukina read his mind, regarding the location of the three remaining bombs. While Aoi and Kazura search the other two stores to extinguish two of the bombs, Yukina and Natsume remain at the store where they are in to disarm the third one. It is revealed that the assailant is Kuse, who was sent to retrieve Yukina. Kuse is a subordinate of Isao with the abilities of teleportation and telepathy. To make matters worse, Aoi finds a young girl in one of the stores, also having to evade Kuse at the same time. As the four spies meet up with each other, Kuse retreats after being overwhelmed with their combined attacks.

Feng Lan requests Aoi and Kazura to have some pictures taken of her restaurant's food so that her menu can compete with a rival Japanese restaurant's realistic replicas. Aoi agrees to do it so he can get a free baozi while Kazura reluctantly complies since they are both professionals. However, after the photo shoot, a cat takes the bag containing the film of the menu as well as the film containing a summer vacation photo of a Japanese lieutenant. Aoi and Kazura are forced to investigate the Green Gang to recover the film, but learn afterwards that the cat took the bag due to the smell of the baozi.

Kazura recognizes his old friend Nishio in a photograph that Aoi has taken in a German delegate's house, resulting in Kazura investigating Nishio's whereabouts. However, he is captured and tortured by the Kuomintang and discovers that Nishio is a spy for the Communist Party of China. Released in exchange for information regarding a weapons smuggling involving the Comintern, Kazura approaches Nishio's lover Ailin, and the two briefly talk about him. During the weapons smuggling, Nishio escapes from the authorities and crosses paths with Kazura, who informs him that Ailin is waiting for him. Nishio disregards it and is later assassinated.

Sakurai reports to Aoi and Kazura that Isao might be involved with the Pan-Asianism movement. It is not soon after until Isao kidnaps Aoi and lets him listen to the Asian delegates' meeting at a tea parlor. Isao voices out his own ideals on Pan-Asianism, later encouraging Aoi to join in his group. Meanwhile, Kazura, Yukina, and Natsume mysteriously find a map toward the tea parlor placed by Kuse. Once outside the parlor, Kuse does his best to prevent them from interrupting.

This episode was streamed exclusively online due to the controversy of the Mukden Incident. It depicts the point of view of the Japanese in Manchuria during the events leading up to the Mukden Incident.[8] It revolves around two young newspaper reporters who are riding on the South Manchuria Railway and run into Kanji Ishiwara, the Lieutenant Colonel of the Kwantung Army who helped devise the bombing so that Japan could attack Manchuria out of "self-defense". Other key historical figures are also present such as Seishirō Itagaki and Yoshitsugu Tatekawa.

After the Mukden Incident, Japan uses the opportunity to seize the entire Manchuria region in the next six months, leading to the establishment on Manchukuo led by Puyi, the last Qing emperor. The League of Nations sends in V. A. G. R. Bulwer-Lytton and his committee to investigate the situation, refusing to recognize Manchukuo as an independent nation. Afterwards, Isao kidnaps the delegation and shows them something as destructive as an atomic bomb in the Taklamakan Desert. He tells them report back to their country leaders of what they just saw along with the demand to relinquish control over countries they’ve colonized. Meanwhile, Sakurai requests the group to investigate on the "prophetess" whom Puyi will be meeting. Kowever, Aoi catches a glimpse of his lover Shizune Yusa, whom he believed to have died before.

Aoi follows the convoy where his fiancée Shizune is, but loses track of her. Going undercover, he infiltrates the building she is residing in, but is confronted by Kazura, undercover as an imperial guard, who expresses his disapproval of Aoi's subordination. Despite Kazura's attempt to stop him, Aoi escapes with Shizune. While in hiding in an abandoned house, Shizune reveals that she cannot leave with him because of her ability of foresight and her responsibility to guide leaders. While Aoi expresses that he will abandon everything to be with her, she disappears when he leaves to find a horse for them to escape. Meanwhile, Yukina meets her brother in the hotel, where she and Natsume are staying in. Isao lets her read his thoughts in which it shows the atomic bombings in Japan. Yukina collapses from shock and upon waking up, she finds the vision too traumatizing.
