"Yes. The Transparent World played an essential role in killing Upper Rank Two, Four, and Six."
"Even in the battle against Upper Rank One, it made a huge difference. Without the Transparent World, you would not be seeing me standing here alive."
Raiden finished speaking and waved his hand casually, dispelling the pressure he had just released.
As the suffocating aura disappeared, the Hashira finally relaxed. Several of them let out quiet breaths without realizing it.
An aura even more terrifying than the Stone Hashira's… just how did Raiden become this strong?
Still, compared to their shock at his strength, what truly caught their attention was the ability he had just mentioned.
They had all seen his fight with Sanemi. At the beginning, he had clearly been at a disadvantage. Then suddenly, everything changed. His movements became sharper, faster, and impossible to predict.
If such an ability could really be learned, none of them would refuse it.
"Does the Transparent World conflict with Mark Awakening?"
Kyojuro Rengoku spoke calmly. He had fought alongside Raiden before, so he was especially interested in what Raiden was saying.
At that time, Akaza had even said that the state Raiden entered was the ultimate realm he had always been searching for.
Learning the Transparent World was obviously a good thing, but the orders from Amane Ubuyashiki and the Master could not be ignored either.
"No conflict. And compared to the mark, which can only be awakened when you are pushed to the edge of death, learning the Transparent World is far more realistic."
"Even if you cannot fully master it, an incomplete Transparent World can still greatly improve your strength."
Raiden had reached it step by step on his own, starting from an incomplete state, so he knew better than anyone that it could be learned gradually.
"In order to open the Transparent World, the key is precision. Your breathing and your movements must become perfectly controlled. You must use the smallest movement to produce the greatest result. When you reach that level, your mind will slowly become clear."
"At the beginning, you need to focus on your senses. Once they begin to sharpen, you must learn to recognize every blood vessel and muscle movement in your body. That stage is usually the most painful."
"After that, you start removing unnecessary movements and keeping only what is essential. When your body reaches the point where muscles and blood flow adjust instantly, almost like blinking, the path will begin to open."
"When your mind becomes completely clear, you will begin to see the Transparent World. But reaching that level always requires extreme effort."
Raiden explained everything calmly, speaking from experience rather than theory.
"It sounds very easy…"
Sanemi started to speak, but the moment he met Raiden's cold stare, he immediately stopped and swallowed the rest of his words.
Fine. Let him talk for now.
Once I learn this Transparent World, I will definitely teach him a proper lesson.
"It may sound simple, but in reality you will face many problems. If that happens, come to me. I will guide you."
Originally, Raiden had not planned to take on such a troublesome responsibility. He had only intended to explain the method and let the Hashira figure it out themselves.
But then he realized something.
Teaching them one by one would make it much easier to get closer to them. Becoming best friends might take time, but becoming friends was simple enough. As long as he guided them properly, none of them would remain completely distant.
With the rewards that came from improved relationships, breaking through to the next level was only a matter of time.
Maybe even Muzan Kibutsuji himself would not escape a beating when the time came.
"Thank you for your contribution to the Demon Slayer Corps. I will leave the Hashira training to you."
Gyomei Himejima clasped his hands together and bowed slightly. He understood clearly that Raiden was different from the nine Hashira.
Raiden was not bound to the Corps the same way they were. If he chose to teach them, it was his own decision. No one had the right to force him.
"It is nothing. Just a small matter."
Raiden smiled lightly. There was no way he would ignore an opportunity like this.
"To make sure the Hashira training does not interfere with the training of the other Demon Slayers, I suggest that each of you come to me one at a time."
Gyomei nodded immediately. It was a reasonable plan. Individual training would make it easier to find each person's weaknesses.
Seeing him agree, Raiden turned his head toward Sanemi.
"Then let us start with you, Shinazugawa."
You think learning the Transparent World is easy, right? Then I will make sure you remember this lesson properly.
And the beating from the first Hashira meeting, I will take it back this time too.
Sanemi suddenly felt a chill run down his spine when he saw the smile on Raiden's face.
Why him first?
"Didn't you say learning the Transparent World sounded easy? What is wrong? Were you just talking?"
The smile on Raiden's face became even wider.
Sanemi immediately forgot all his doubts. He only cared about one thing now. He absolutely could not let Raiden look down on him.
"Of course not. I just reacted a little slowly. If I am first, then I am first. I will prove it with my actions."
"Good. Training starts tomorrow."
Raiden looked genuinely pleased. Things were about to get interesting.
Seeing that Sanemi had been chosen first, Rengoku blinked in disappointment. He had actually hoped Raiden would pick him.
"Then this Hashira meeting ends here. Raiden will handle the Hashira training, and the rest of you will continue training the Demon Slayer Corps members."
"I hope everyone will be fully prepared."
"Meeting adjourned."
Gyomei finished speaking and clasped his hands together once more before officially ending the meeting.
After everyone began to leave, Raiden turned to head back to the Butterfly Mansion.
But after taking only two steps, he suddenly stopped.
He stood there for a moment, thinking quietly, then slowly turned around.
