沖田総司
After the start of the Boshin War, he and Mitsu took care of a terminally ill Okita Sōji until the forces of the northern domains, as well as the soldiers of the former shogunate, retreated to the Tohoku region. Since Sōji was not fit for traveling, Rintarō and Mitsu had no choice but to leave him in Edo. Joining the Shōnai daimyō Sakai Tadazumi in leaving the city, Rintarō and his family traveled to Shōnai. Rintarō subsequently fought alongside the Shōnai forces during the height of the Boshin War. In 1872, the family returned to Tokyo and lived in a place called Ume-yashiki (梅屋敷; "Plum Mansion") in Sumida-Mukaijima. Okita Rintarō died in Tokyo, on February 13, 1883, at age 56.
