After the death of his best friend Yoshitoki Kuninobu, he vows to
protect Kuninobu's crush, Noriko Nakagawa, in his stead.
In 1900, Kojuro Nakagawa(the former secretary of Prince Saionji)
established the Kyoto Hosei School, a law school that eventually adopted the Ritsumeikan name(with the prince's permission) and was awarded full university status in 1922.
