Saki swears at her father's tomb that she will avenge him. She wants to know the story about her father but Nishiwaki wouldn't let her know, saying that she is still not mature enough.
While practicing yo-yo, a blind old man approaches her and teaches her the trick of using two yo-yos. This man is Duke Nango, who actually once targeted Saki's father's life and also battled with Nishiwaki who was serving as a bodyguard of Saki's father, who was an archeologist. Saki confronts Nishiwaki to show how matured her skill is and throws a secret second yo-yo towards him. She thought it was a yo-yo which contains water, but it actually contains a poison given by Nango. Nishiwaki is beaten.
Getting mad, Saki confronts Nango but she is still not an enemy of Nango. Nishiwaki then appears and beats Nango by a combination play with Saki. Nishiwaki mumbles, "he also would be a victim of that man......", does he mean Kyoshiro?
