Okita Sōji
Okita changed his name to Okita Sōji Fujiwara no Kaneyoshi some time before his departure with the Rōshigumi to Kyoto on March 26, 1863. However, the Rōshigumi was disbanded upon their arrival there on April 10, 1863, while the rest returned to Edo. Okita and several other founding members remained behind in Mibu to form the Mibu Rōshigumi, which would later be renamed as the Shinsengumi on August 18, 1863. Okita was the second youngest among the Shieikan members, most likely with Tōdō Heisuke being the youngest. His brother-in-law Okita Rintarō, also a practitioner of the Tennen Rishin-ryū, became a commander of the "Shinchōgumi" (the Shinsengumi's brother league in Edo.)
