The universe begins with Demon Slayer: Kimetsu no Yaiba

"that."

Tanjiro just said two words, and the man in front of him immediately took the initiative to introduce: "My name is Steel Mound. I made and brought Shiroha and Kamado Tanjiro's swords."

Hearing this, Tanjiro bowed to the Iron Tomb, and then said: "Um, Kamado Tanjiro is me, Bai Yu is my senior brother, please come in!"

But Steel Tomb sat down with his back to Tanjiro, then took off the long box on his back, and said as if he was about to take out the contents of the box: "This is the Nichirin Sword, the sword I made. .”

Seeing that the other party did not intend to enter the house, Tanjiro felt helpless and had no choice but to continue: "Well, please come in first and I will make you a cup of tea!"

The Iron Tomb still had no intention of entering the room, and continued to mutter to himself: "The raw materials for the Sun Lun Knife can be mined from the mountains closest to the sun, using {gorilla crimson sand iron} and {gorilla crimson ore}, and then Can create iron that absorbs sunlight.”

"Really?" Tanjiro had no choice but to respond to Iron Tomb's words in order to prevent the atmosphere from being awkward.

"After all, Sunshine Mountain is a mountain where the sun shines all day long." At this time, Iron Tomb stood up and pointed to the sun in the distance.

In the wooden house, Ningtaki Sago complained helplessly for the first time: "This man is still not listening to what others say~"

Suddenly Iron Tomb turned around and put his face in front of Tanjiro. Seeing the ugly mask on Iron Tomb's face, Tanjiro was startled and couldn't help but take a step back.

"Um~ Aren't you {Hezhuo's son}? This is really auspicious!" Iron Tomb looked at Tanjiro through the mask and said with some surprise.

"No, I am the son of Tanjuro and Aoi Eda." Tanjiro quickly denied and explained.

"do not mean that!"

Steel Tomb pointed at Tanjiro's hair as he spoke, and then continued: "Your hair and eyes are red, right? If a family engaged in fire-related work gives birth to such a child, they will be happy because of the auspiciousness!"

After saying that, Steel Tomb poked Tanjiro's face with his finger.

Tanjiro understood this, and could only reply awkwardly: "Is that so? I don't even know!"

"It seems that your sword might turn red! Right? Lintaki!" Iron Tomb said, and called into the room.

Rintaki Sakon, who was in the room, responded in a deep voice.

After that, Steel Tomb entered the wooden house with the finished Nichirin Sword, and Tanjiro quickly followed.

After Iron Tomb entered the wooden house, he sat down next to Lintaki Sakonji, while Tanjiro sat back next to Bai Yu, and then began to make tea for Iron Tomb.

Iron Tomb placed the Nichirin Sword in front of Bai Yu and Tanjiro, and then Iron Tomb looked at Bai Yu, and then said: "It's such a rare hair color, it actually has two colors, although there is only a little bit of blue. "

At this time, Tanjiro handed the brewed tea to Iron Tomb and said: "Mr. Iron Tomb, please drink tea!"

As for Bai Yu's hair, after turning on the ghost transformation, Bai Yu's black hair completely turned milky white over time. After two years of training in Mount Sagi, perhaps because the body had completely mastered the use of water breathing, the ends of Bai Yu's hair began to turn blue.

As for such a change, Bai Yu couldn't explain it clearly.

However, the rare hair color does make Bai Yu look more unique.
