On the road to Mt. Sagiri, Haku began subtly probing for information about the Demon Slayer Corps.
One of the Demon Slayer Corps members Haku had saved earlier, a man named Ichiki, said, "Our Demon Slayer Corps has a long history. For centuries, we've fought demons in the dark and protected the countless people of this world!"
Another member, Hirozane, nodded proudly. "That's right! The only reason you've grown up without ever knowing demons existed, Ice, is thanks to us!"
Haku fell into thought at their words.
After learning about the origins of the Demon Slayer Corps, he thought to himself, I never expected this world to have an organization like the Demon Slayer Corps, one that's been entangled with demons for centuries. It seems my decision from the start was the right one. If I join the Corps, I should be able to get information about demons easily!
Ichiki said, "Ice, you have the greatest talent of anyone I've ever met. Once you master the Breathing Technique, you should become an excellent Demon Slayer swordsman!"
Haku looked puzzled. "The Breathing Technique!?"
"Mm. The reason our Demon Slayer Corps can stand against demons is the Breathing Technique, which enhances our strength and speed. You can only be considered a true Demon Slayer swordsman after you've trained in it!"
Ichiki seemed to have already accepted Haku as one of their own and explained everything to him earnestly.
Haku asked, "Then, Senior Ichiki, have you also trained in the Breathing Technique?"
He honestly couldn't tell how Ichiki and Hirozane's physiques or speed had improved from training in the Breathing Technique.
"Of course!"
Ichiki nodded proudly.
Hirozane added, "You don't need to rush. Mt. Sagiri, where we're headed now, is one of the Demon Slayer Corps' training grounds. There's a legendary senior there!"
