I've just seen episode 3. The fight is so intense and simply great. However, I still think the fight in the book is better.
Spoiler for the fight (book, in detail):
Barsa gets ready to fight when she enters the rice field, because she knows that if someone follows her, they will attack her where there's no place to hide. The Hunters are so good at stealth she notices them only after the first shot of Jin's blowpipe. She prevents the second shot by throwing shurikens at him. Chagum cannot run away, and just lies on his face. She protects him from the three Hunters (other than Jin, who is away from them) and in a moment she fails to protect Chagum and Yun doesn't kill him, she instantly understands they are not going to kill him. (She doesn't ask them why, of course.) She stops protecting Chagum, stubs Zen's shoulder and tuckle him, and escapes leaving Chagum behind. (She's realistic and doesn't hesitate to flee if it gives her a better chance.) She runs into the forest and a moment later counterattacks them. She cuts Yun's face, gets cut on the stomach by Mon, and knocks him down. (
the picture of the scene in the book) She hides in the forest. Jin fails to find her because she doesn't move at all for minutes.
Later, she attacks Jin near the river, who carries Chagum alone. The fight is as intense as the first fight. She cannot fight as strongly as usual because of the injury. She breaks Jin's left arm's bone, but she also gets cut on the left arm. Suddenly, the egg in Chagum glows and affects water again, and both Barsa and Jin fall down into water. Jin drops his sword in the river, and she throws her spear, stubbing him unconcious. She doesn't waste time to kill him, in order to flee with Chagum as soon as possible. She carefully chooses where to leave the river to avoid being traced by their footprints. Then she falls unconcious.
Barsa's spear never breaks in the book and there's no story between Jin and Chagum. Lastly, everybody knows they can't run in the rice field!
By the way, Barsa in the anime is good though too young, but Tanda looks quite different. It's written he is a babyface and has a round nose. (
Tanda in the book)
