[Machine Translation] Behind the transformation of Ryoma from a sniveling teenage dropout to a Bakumatsu no Shogun at the age of 32, when he formed the Kaientai, lay a mysterious faith and a woman who fascinated him throughout his twenties. Among them, Sana, the daughter of Sadakichi Chiba, the master of the Hokushin Itto style dojo where Ryoma practiced in Edo, guided him to the secret art of the Chiba family, which is based on Myoken Bosatsu (Myoken Bosatsu is a guardian deity). Ryoma then pushed forward with the modernization of Japan, only to be assassinated and die a short death. What was it that drove Ryoma? The author, who was born in Tosa and devoted his life to politics, presents a controversial theory of Ryoma.
