One day in July 1867, the Shin-kōkyo Group, a Kyoto "active" group responsible for protecting the peace and order of Kyoto, received information from Kyoto-soji, who pointed out that a businessman named Yuya Kiemon in Mamachi had a problem because he had a very shabby shop selling firewood, coal, and living utensils. It is said that this is just a small and inconspicuous shop, but this shop often welcomes a large number of ronin, and these ronin do not buy anything, empty-handed and empty-handed. This unreasonable situation led to suspicion by Kyoto Sodai, so Kyoto Sodai asked the new selection team to investigate this person.
In fact, the new selection team has also been paying attention to this man for some time, and has been monitoring him since June, and now that kyoto soji is speaking, it is just a good idea to grab him. The deputy leader of the newly selected group, Tokata, immediately decided and ordered a group of team members to secretly capture Yuyaki's right guard. Before leaving, Tufang Repeatedly told the team members that they must secretly arrest YuYaxi Right Guard Gate, otherwise if there is too much movement, perhaps Yu Yaxi Right Guard Gate's accomplices will hear the news and flee, then there will be no way to talk about cracking the other side's conspiracy.
The shin-kun group is usually in charge of kyoto law and order, and is the most outstanding of many teams, arresting a Yuya Ki Right Guard Gate HoZumi Michiya, and on July 8, the Shin-kō group secretly arrested YuYa Yoshi Right Guard Gate and brought him back to the Shin-kun group's Tunsho for interrogation. Because the mouth of this Yuya Xi Right Guard Gate was too hard, the newly selected group Tokata Shizo personally interrogated Yu Ya Hi Right Guard Gate. According to the newly selected team members in the aftermath, the hands of the three members of the Turkish side were very fierce, and the Yuya xi right guard door was almost out of human form, and even the bravest team members in the newly selected group did not dare to look directly at the interrogation scene of the third time of the new selection, which can be described as "the viewer has looked sideways, and the team members do not dare to force their eyes."
Yu Yaxi's right guard could not withstand the torture of Tufang Shisan, and could only recruit everything he knew. Yuya ki right guard said that his real name was Kokaka Shuntaro, a spy sent to Kyoto by the Choshu Clan, and his mission was to act as the choshu clan's eyeliner in Kyoto. At the same time, he also confessed a shocking conspiracy - the Choshu Domain planned to take advantage of the Gion Festival to set fires everywhere in Kyoto Castle, so as to disturb people's ears and invade the interior of the Imperial Palace at the same time, take the opportunity to kill shogunate leaders such as Keiki Izutsubashi and Matsudaira Yōho, and kidnap the Emperor to go to Choshu Domain.
As soon as these words came out, Togata Shizo really broke out in a cold sweat, and hurried to contact the leader of the new selection group, Kondo Isamu, and after the two of them summed up a little, they decided to take action immediately, on the one hand, to contact aizu domain and Sangming domain, asking them to send troops to search for the chaotic party thieves of the Choshu domain, and on the other hand, to organize the members of the new election group to prepare to arrest people in the place where the thieves were most likely to hide. However, due to the slow movement of the Aizu and Kuwana clans, only the new selection group gathered the existing manpower to carry out the search at night.
At that time, most of the members of the new selection group had tasks and were not in the station, so after the new selection group gathered manpower, only 34 people were assembled. Considering that the new selection group was seriously understaffed, 23 members of the Togata Razaka Group searched the area around the Yasaka Shrine, which was larger, while Isamu Kondo searched the area around the Sanjo Bridge with nine members of the new selection group, including Heisuke Fujido, Shinpachi Nagakura, and Soji Okita.
Instead of hiding in the direction of Togata's search, the choshu clan rebels were hidden, but the smaller Kondo found the Choshu clan rebels at the hotel "Ikedaya". Kondo ordered five of his men to scatter around and surround Ikedaya, and he personally led four people, including Heisuke Fujido, Shinpachi Nagakura, and Soji Okita, to rush into Ikedaya and fight with the Choshu Clan Rebellion. At that time, there were dozens of people in the Choshu Clan rebellion in Ikeda House, and the number of people had an absolute superiority over Kondo Andyo and others, but Kondo Yong heard that the core figure of the Choshu Clan, "Katsura Kogoro" (Kido Takayoshi), was also here, so he led people to raid the second floor of Ikeda House, hoping to kill Katsura Kogoro in one fell swoop.
Kondo Isamu led by the new selection group of the masters, when it comes to personal combat strength is definitely stronger than the Choshu Clan Chaos Party, but the choshu Clan Chaos Party numbers dominate, so under the siege of the other side, Kondo Isamu and others were quickly scattered, and when Kondo Yong killed the second floor to find Katsura Kogoro, there was only one Okita Soji left around. Although Fujido Heisuke and Nagakura Shinpachi downstairs want to support Kondo, they are now surrounded by many people and are in a state of being cut down, and they are unable to get out and rush to the second floor, and can only support themselves on the first floor.
At the critical moment, Toho finally arrived at Ikedaya with reinforcements, the numerical superiority of the two sides was reversed instantly, and as Tokata and others joined the war, the Choshu Clan Rebellion Party in Ikeda House finally could not support it, and seven members of the Choshu Clan Rebellion Party were killed, eleven were seriously injured, and more than ten others were captured, and the rest escaped from Ikedaya in the chaos. On the part of the new group, only two people died of serious injuries, and Soji Okita suffered a seizure of tuberculosis and was bedridden. However, in any case, the plot of the Choshu Domain to burn Kyoto was also cracked, otherwise Kyoto, the ancient capital of the millennium, might have been burned to the ground by the rebels, and the new selection group was also famous for the Ikedanya incident and became an important security force in Kyoto.
