Hōjō Tokimasa
A powerful earthquake strikes the capital. Minamoto no Yoritomo's distrust of Minamoto no Yoshitsune grows. Yoritomo sends an assassin to kill Yoshitsune (fails). Then, Yoritomo kills Minamoto no Noriyori (Yoshitsune's half brother) who is reluctant to go against Yoshitsune. When Yoritomo sends a large force led by Hōjō Tokimasa against him, Yoshitsune flees from the capital to a northern province.
