Demon Slayer : Kimetsu no Yaiba (chapter 17 explanation)

 

Chapter 17:- The Arrow pattern Demon

The chapter begins with Yushiro reminding Tanjiro to stay vigilant; there's a possibility they could be up against two of the Twelve Kizuki. Yushiro suggests to Tamayo that they should run while the enemy is distracted with Tanjiro and Nezuko. When she gives him a horrified look, he says he was "just kidding."

Meanwhile, Nezuko has gone after Yahaba and makes him angry by kicking up some dust near him, using his arrows to toss her away. Tanjiro is occupied with Susamaru and is shocked by her regeneration speed.

Nezuko and Tanjirou swap places

From the sidelines, Yushiro tells him to get rid of Yahaba first and he and Tamayo will work with Nezuko to handle Susamaru. Before continuing on to Yahaba, Tanjiro tells Nezuko to be careful and the girl has a flash where she briefly sees Tamayo and Yushiro as her mother and brother which causes her to grow determined to protect them.

Yahaba disbalanced Tanjirou

Facing off with Yahaba, Tanjiro sees the line of interval, but it very quickly disappears when Yahaba tells Tanjiro to stay away from him, using arrows to throw him off balance. The arrows continue to drag him around and he breaks a fall by using Water Breathing: Eighth Form - Waterfall Basin. As everyone continues to fight, Yahaba recognizes Tamayo as the demon who broke free of Muzan.

Nezuko try to kick temari ball 

Susamaru throws one of her temari balls at Nezuko, who moves to kick it only for it to detach her leg and causing her to fall. Susamaru gets excited and asks Yahaba if they can bring back all four of their heads but he denies her, saying only Tanjiro and Tamayo are their targets.

Tamayo gives Nezuko some medicine to help the regeneration speed of her leg. Tanjiro begins to decipher the patterns of Yahaba's attacks and manages to save his arm from being twisted by using a technique to twist himself the same way and loosen the arrows. Growing tired from repeatedly using so many techniques, Tanjiro uses a last ditch modified Water Breathing: Second Form - Lateral Water Wheel, to finally behead Yahaba.
