"The Hitotsubashi Yoshinobu, highly esteemed by the 'Hitotsubashi Faction' for his virtuous reputation, is the biological son of Tokugawa Yoshiaki and was adopted by the heirless Hitotsubashi family in Kōka 4 (1847)."
"Whether for the future of his own son or the benefit of his family, Tokugawa Yoshiaki naturally hopes that his own son becomes the new General."
"Thus, in the succession dispute two years ago, Ii Dairou was the staunchest supporter of the Nanki Faction, while Tokugawa Yoshiaki was the firmest advocate for the Hitotsubashi Faction."
"After Ii Dairou successfully ascended to the position of 'Tairō' and the 'Nanki Faction' emerged victorious, Ii Dairou began to vigorously suppress all political opponents, led by the 'Hitotsubashi Faction'."
"Tokugawa Yoshiaki, who had constantly opposed him, naturally became a target of Ii Dairou's strict measures."
