The universe begins with Demon Slayer: Kimetsu no Yaiba

Suddenly, countless flaming curved blades gathered and rotated in front of Bai Yu. The ice blades shot out by Yiwozuo Luo Needle and Ice Flower Needle suddenly hit the shield formed by the flaming curved blades.

 The next second, the heavy rain lost its barrier and fell again.

 A large number of exploding ice blades collided with the shield formed by the flame curved blade, shattered all of a sudden, and were then evaporated into water vapor by the high temperature.

Just when Bai Yu and Yi Wo Zuo were facing each other again, Duo Ji took the initiative to summon her brother: "Brother! Come out quickly, Duo Ji needs your help!"

At Duo Ji's summons, Duo Ji's back suddenly arched up, as if something was about to break free from her body, and her figure was also pressed to the ground.

 In the end, we didn’t see Duo Ji’s brother breaking out of Duo Ji’s back. Instead, Duo Ji’s brother split from Duo Ji’s body.

What separated from the body of Fallen Princess was a strange man with a stooped body and ugly facial features, as well as large black spots.

This man is the ugly brother of Duo Ji whom Yiwozu said. His name is Jifu Taro. He maintains a symbiotic relationship with Duo Ji. He usually stays in the body of Duo Ji. Only his sister takes the initiative to call him, or when he encounters problems that cannot be solved. Things will come out when something happens.

So the Sixth Chapter of the Upper String does not refer to just Touji, but to the symbiotic brother and sister, Touki and Ji Futaro.

"My beautiful sister, what's wrong? Where is this place? Why isn't it in Flower Street?" Jifu Taro murmured to Fouji after he came out.

　　ji Futaro's voice was very hoarse and lifeless, making people feel as if he would die at any time.

"Brother, you are here to help Mr. Yiwozuo deal with that white-haired boy. I am going to complete the task assigned to me by the adults!" Duo Ji also briefly explained to her brother for a while, and then immediately got up and took advantage of Bai Yu. Kongza, who was restrained by Yiwoza, immediately chased after Tanjiro who had run away.

Tailang didn't ask any more questions, and quickly turned to Bai Yu, and then the blood that spread in the palms of his hands suddenly formed two small sickles.

On the other side, in the collision between ice and fire, Bai Yu's fire finally won the victory, and Yiwozuo's green eyes failed to break through Bai Yu's Shengyan vortex.

 Finally, the ice blades of Yiwozuo’s compass needle and ice flower needle all dispersed. The rotating flame curved blade guard in front of Bai Yu turned into a fire phoenix and swooped towards Yiwo Zuo in the next moment.

 Bai Yu was also very surprised by Jifu Taro's appearance. After all, Bai Yu thought that the Fallen Princess would only change its form at that time. Unexpectedly, it split into a new individual, which changed the situation.

So even if Bai Yu immediately stopped Duo Ji from leaving, Jifu Taro would definitely stop him, not to mention that Bai Yu was still confronting Yiwo Zuo at that time and could not take action to deal with it for a while.

　　ji Futaro had no intention of helping Yi Wo Zuo block the attack, but directly attacked Bai Yu.

The fire phoenix transformed from the Shengyan vortex directly impacted Yiwozuo's belly. Because Yiwozai's body was damaged by the White Feather Purgatory Meteor, it has not completely recovered, and its body has not returned to its best condition. In addition, the distance is very close, so there is no possibility for Yiwozuo to dodge.

Fire Phoenix immediately opened a big hole in Yiwozuo's abdomen. Yiwozuo, who was hit hard again, opened his mouth wide and coughed out a mouthful of blood.

Although this was a good opportunity to kill Yiwo Zuo, Jifu Taro's intervention prevented Bai Yu from continuing to pursue Yiwo Zuo for the time being.
