Serizawa Kamo - Mibu Roushigumi/Shinsengumi Period

Mibu Roushigumi/Shinsengumi Period

After their arrival in Kyoto, Serizawa and Kondou's group separated from the Roushigumi, becoming an isolated group. A few weeks later, Serizawa and Kondou decided to submit a letter to the Aizu clan asking to join them in policing Kyoto. The Aizu clan were assigned by the Tokugawa regime to police the streets in Kyoto by samurai (most of them lower-class samurai from Chōshū, Tosa, and other states) who rampantly started fights and committed assassinations. The idea of working under the Aizu may have originated with Serizawa's older brother, who had connections with the Aizu clan. The Aizu clan accepted the letter's request, making the twenty-two samurai into a group under the Aizu clan.

It was then that the group began calling themselves the Mibu Roushigumi and Serizawa becomes the lead captain.

However, Serizawa started numerous incidents. On July 18 (lunar calendar June 3), Aizu commanded Mibu Roushigumi members to police Osaka. Serizawa and his group were out drinking and later Serizawa got in a fight with a sumo. This created a conflict with the 25-30 sumos in the same dojo. Serizawa's group had only ten or so members but managed to overcome their attackers. At the end ten sumos were dead and the rest had sustained serious injuries, yet Serizawa's group barely had any injuries at all. News of this incident spread quickly, enhancing the Mibu Roushigumi's reputation. Later in June, Serizawa had a drinking gathering with his members in a restaurant in Shimahara. He lost his temper while drinking and wrecked the whole restaurant; the restaurant had to be closed for business because of it. On September 25 (lunar calendar August 13), Serizawa and his group destroyed Yamatoya, a silk cloth store, in daylight with a cannon given to the group by the Aizu clan when they would not give them money.
