Baki Season 3 Episode 20, which is currently available on Netflix, started with the conversation between Mitsunari Tokugawa and Kunimatsu, the master of one of the death row inmates Ryuukou Yanagi. Kunimatsu explained the secret behind Yanagi's fighting technique, including the poison hand.
Baki Season 3 Episode 20 revealed that in order to turn his hands into a lethal weapon, Yanagi first gathered different types of poisonous insects and plants, grounded all of it, and mix it with sand. To neutralize the poison, Yanagi also put his arm in a jar full of antidote. Kunimatsu said that it's not as easy as most people think, and some of them decided to cut their own hands because of the extreme pain.
Kunimatsu also talked about the whip strike which is mastered by Yanagi. To be able to use the technique, the user should think of himself first as a liquid. It allows the user to turn any areas of his enemy's body into vital points. When an enemy is hit by the whip strike, he experiences an unbearable type of pain.
Baki Season 3 Episode 20 also featured more intimate scenes between Baki and his girlfriend Kozue. It was very noticeable that both Baki and Kozue were shaking and already felt the warmth of each other's body even without touching each other. Kozue made the first move by touching Baki until they finally started kissing each other.
As the action in his old house continues to get intense, Baki realized the similarities and differences of what they are doing and fighting. The battle between Baki and Kozue went for days until the room was covered with used tissues. Their intimate fight ended with both of them having a smile on their faces.
