When the elderly John and his grandson admired the samurai swords, they aroused his longing for Japan.Mariko and Toranaga's family hid in a solid warehouse to avoid being hunted.The ninja tried to use explosives to blow open the warehouse door, and Mariko was blown away while protecting everyone.John was distraught and supported the dead Mariko.The story then moves to Osaka Castle, where Ishido faces pressure from other lords due to the crisis in the Toranaga family, forcing him to release all the hostages.Through the conversations among the lords, we learned that Mariko’s purpose in coming to Osaka Castle was to confront Shido and destroy the harmony among the lords.Ishido kept the lord's family for safety reasons, but Mariko's death made people doubt him and broke his relationship with the lords.There are also hints that the attack may have been planned by Toranaga and Mariko.

Lord Ohno wanted to hold a Christian burial for Mariko, but Ishido objected, but was finally persuaded by Lady Fallen Leaves to accept.Stone Hall ignores John's safety and the earthquake causes chaos.Shitang visits Suo Zhong and finds that he is still in deep pain.John woke up and learned that he could leave, but it was Lord Shanmu who signed the permission, which confused him.The priest discussed Toranaga's future with him, believing that Toranaga's time was numbered, but John believed that they did not understand Toranaga, and that Toranaga's real purpose was to abort the hostage plan, which had been completed by Mariko.The priest said that it was Mariko's arrangement that John was able to leave Osaka alive.People appreciate Mariko's actions and firm belief. Even if her fate is tragic, she always insists on implementing her beliefs.

Suo Zhong knew that he could not escape his guilt and hoped to escape Japan with John, but John encouraged him to be strong.When John saw his boat stranded on the beach, he was deeply depressed.He discovered that Suo Zhong was controlled by his nephew Yang Hai and that everything was under the instructions of Hu Yong.He learns that this is a group of Christian-like people sabotaging ships, and suspects that Mariko is the instigator.Toranaga sees the chaos and scarring of the village and becomes determined to find out who sabotaged the ship.Sonaka was brought to see Toranaga, identified as Osaka's attacker, and asked to commit suicide as an apology.He wishes to die quickly, but is rejected by Toranaga, who agrees to be his assistant in committing suicide.That night, John's wife, Mrs. Fuji, told her that she wanted to become a monk. She rejected John's request for her to stay and said that she had completed Toranaga's mission.Looking at the broken ship and the dead, John grieves and hopes to see Toranaga.

John thought in the early morning courtyard.After being taken away by Yang Kai, John handed over all his weapons and said goodbye to Mrs. Fuji before heading to see Toranaga.Toranaga is furious that John's ship was sabotaged, and John apologizes to him and reveals Mariko as the culprit.But John's apology could not dispel Huyong's firm attitude, causing John to stop until he wanted to die.However, Toranaga lets him live, suggesting that he build a fleet of ships to end the massacre.In the evening of the same day, Suozhong came to see Toranaga and expressed his expectations for his expansion and asked him if he was willing to become a general.Finally, the rejected Suo Zhong got a clear answer to Hu Yong's death.John and Mrs. Vine scatter Mariko's ashes on the beach and throw away Mariko's cross.Looking at everything, Mrs. Teng smiled.The villagers are busy preparing for war, and the Sekigahara War is about to begin.
