Okita Sōji
A licensed practitioner of the Tennen Rishin Ryu, in 1863 he joined the Rōshigumi together with Okita Sōji and Inoue Genzaburō. However, not long after their arrival in Kyoto, the Rōshigumi was disbanded, he and the rest went back to Edo, leaving behind Okita Sōji, Inoue Genzaburō and few members there. While in Edo, he later became a commander of the Shinchōgumi, which was under the sponsorship of the Shōnai-han. At that time, he and Mitsu moved to one of the barracks ("kumi-yashiki" 組屋敷) in the former Edo residence of Tanuma Okitaka with their children. They lived there until the Boshin War.
