Teruhi invites Jinzaburō to a strategy conference, but is ejected by Sō Sukekuni after disagreeing with his assumption that the Mongols will pass Tsushima. He meets Shōni Kagasuke, dressed as a monk, who asks him to help defend Tsushima for 7 days while he readies reinforcements, presenting him with the favourite sword of Minamato no Yoshitsune. The next day, the Mongol fleet lands at Sasu Bay and Sō Sukekuni rides overnight with his forces to meet them. Sō Sukekuni orders Jinzaburō to the rear to protect Teruhi and prepares to repel the invaders. After withstanding volleys of arrows from the advance party of Mongols, Sō Sukekuni's men push them back to the shore where they find the Sasu villagers slaughtered. However after the initial victory, the force of 200 soldiers and 80 horses are assaulted by explosives fired from the ships and are overwhelmed by a larger force of 1,000 Goryeo soldiers and Sō Sukekuni is killed.
