They won the Holy Grail War, but this turned out to be the Virtual Tree Universe.

Chapter 10 Danlei: Tanjiro, can I borrow your sister to study?
Giyu Tomioka implied that Nezuko was the demon who killed the charcoal seller's family, which Tanjiro naturally noticed, so he quickly explained loudly.
"No, I am the eldest son of the charcoal sellers in the mountains!"

Nezuko is my sister and mother. She didn't kill Takeo, Shigeru, Rokuta, or Hanako.

I also smelled a stranger's scent at the scene. The killer must be carrying that stranger's scent!!

Giyu Tomioka didn't believe Tanjiro's explanation because he had seen too much of it.

Giyu Tomioka believes that the boy is simply unable to accept that his sister has become a demon, and is therefore trying to find reasons to protect her.

However, Dan Lei felt that the time was right and it was time to increase Tanjiro's affection level, so he went along with his words.

"I don't know if there are other ghosts, but it's probably true that the charcoal-selling boy said his sister isn't a murderer's ghost."

Because I personally witnessed the girl completing her final demonic transformation on his back; before that, the girl shouldn't have had the ability to kill.

Giyu Tomioka doesn't believe Tanjiro's words, but Danri's words do have some credibility.

But since the girl named Nezuko is already a demon, the outcome will not change.

So Giyu Tomioka said seriously to Dan Lei

Even so, this girl is already a ghost. Giving her a quick release is the greatest mercy.

To maintain his public image, Danlei nodded in agreement, planning to find another opportunity to prove Nezuko's special status to Giyu Tomioka later.

But Tanjiro panicked when he heard that Nezuko was still going to be killed.

However, his feet were frozen by Dan Lei and he couldn't break free at all. So in a panic, he broke off his boots in the freezing cold and shouted "No!" as he charged straight at Dan Lei.

When Dan Lei saw Tanjiro charging at him again, he thought Tanjiro was still planning to headbutt him, and was about to use the same trick to throw him out.

As a result, Tanjiro rushed over and knelt down in a standard dogeza, his head sliding right up to Tanjiro in the snow, and then pleaded with unusual sincerity and sobbing.

"Please stop! Please don't take anything more from me. Please, spare my sister! She won't eat people, I'll heal her, sob sob~~"

In Japanese culture, dogeza is actually an extremely extreme form of expression. In the Taisho era, this action had not yet been popularized.

Bowing to a stranger is considered a great humiliation at this time, and it is only used in extreme circumstances when there is absolutely no other way.

Tanjiro's current prostration to Tanjiro can be interpreted as him saying, "You can do whatever you want to me, I'll even give you my life, but please spare my sister."

Tanjiro's actions somewhat disrupted Danri's rhythm.

However, just as Danlei was preparing to use the opportunity of educating Tanjiro to release Nezuko, thus demonstrating the cruelty of demons, and then let Giyu Tomioka see Nezuko's actions in protecting Tanjiro,

Just like in the anime, Giyu Tomioka was furious when he saw Tanjiro's actions.

In the original anime, Giyu Tomioka speaks more in the next few minutes than he does in the entire following season combined; it's too long to repeat here.

But to sum it up, it all boils down to one thing.

"What's with your behavior and your tears? Will these tears save your sister? If they were effective, this tragedy wouldn't have happened!"

You are too weak! Weakness means being unable to protect! Weakness means your words carry no weight! Weakness means only loss! Because of your weakness and incompetence, you lost all your family, and now you're here crying?

Giyu Tomioka's words deeply wounded Tanjiro's heart. Then, as if going berserk, Tanjiro roared and drew the axe from his waist, then swung it at Tanjiro.

This time, Sasaki Kojiro will not make a move because he knows that Tanjiro has no chance of hurting Tanjiro.

However, Danlei said that this was an undeserved disaster for him. "I wasn't the one who insulted you, so why did you cut me?"

However, Tanjiro's axe was easily caught by Danrui with two fingers.

Unfortunately, Tanjiro hadn't been trained at this point, and no supernatural power was attached to his axe.

Even Dan Lei could see this axe blow clearly, but by wrapping his fingers with the power of abundant destiny, he easily caught it.

For those who follow the path of destiny, fighting while completely enveloped in the power of destiny is a basic skill. Only by breaking through the protection of the power of destiny can one more effectively kill those who follow the path of destiny.

Of course, the power of destiny can also be attached to weapons and bullets, which can allow travelers from backward civilizations to break through the defenses of advanced civilizations.

After all, the combat power of the Fate Walkers from technologically backward planets is not necessarily weak.

At this time, Dan Lei was only a newcomer among the Destiny Walkers. Let alone comparing him to the universe, he couldn't even be considered the strongest in the small world of Jinren Alley.

But Tanjiro is definitely enough to restrain ordinary people.

However, Dan Lei, who was holding the axe between two fingers, immediately felt that the axe was not under any force, and that Tanjiro was not swinging the axe with his full strength at all.

From a third-party perspective, Tanjiro actually let go of the axe halfway through his "all-out" swing at Danlei. He then used the momentum to rush to Danlei's left, and then, like a spring, he turned and leaped to the right, bypassing Danlei and directly attacking Nezuko, who was bound in the air.

Normally, given the strength of Tanjiro's magic strings, even if Tanjiro pounced on Nezuko, they would only end up hanging in the air together.

But Danlei saw this as a good opportunity and deliberately loosened the magic strings, allowing Tanjiro to tackle Nezuko to the ground.

Seeing this, Giyu Tomioka knew something was wrong. The demon's restraints had been broken, and the boy was about to be attacked.

However, after Tanjiro rescued Nezuko, the first thing she did after breaking free from her brother's embrace was to spread her arms and block Tanjiro, staring at him with a ferocious expression, as if to say, "If you want to hurt my brother, you'll have to step over my body."

Seeing this, Giyu Tomioka was completely dumbfounded.

Because newly born demons have the strongest appetite, this demon named Nezuko was able to suppress her appetite and refrain from attacking in order to protect her brother. This was the first time I had ever seen such a thing.

Seeing that his goal had been achieved, Dan Lei smiled, half-seriously and half-jokingly saying to Tanjiro...

"Interesting. So, it turns out that ghosts, like the Dead Apostles, can also maintain their rationality from the beginning?"
"Tanjiro, it looks like your sister won't die for now. But, let me study her a bit; I'm very curious about her, inside and out."

Tanjiro was initially quite happy to hear Danri say that his sister wouldn't have to die for the time being, but he almost lost his composure when he heard the second half of the sentence.

Moreover, Tanjiro's nose told him that this Mr. Danlei wasn't entirely joking; he was quite serious.

So, Tanjiro once again shielded Nezuko behind him and said firmly.
"Mr. Danlei, I'm sorry, my sister is not of marriageable age yet, so I can't give you a full overview of everything."
