The Mugen Train.
Everyone trapped in dreams, their lives hanging by a thread.
Just when countless worlds held their breath for Tanjiro and his friends—a turning point appeared.
The charcoal seller boy, lost in the blissful illusion of reuniting with his family, was the first to awaken.He realized what he saw was nothing more than a false mirage.
To break free,Tanjiro chose a path almost no one would dare.
Without hesitation, he turned his blade on himself—and returned to reality.
And in that very instant,he was already prepared for battle.
After asking Nezuko to wake the others,he climbed alone to the roof of the speeding train, standing face-to-face with the terrifying Lower Moon One, Enmu.
What followed left all who watched shaken.
Confronted by Enmu's blood demon art that forced him into endless sleep,Tanjiro slashed his own throat again and again the moment he realized he was dreaming, breaking free each time.
The heavens and worlds cried out—
"Insane! That boy's completely insane!""This is madness!""He treats his own life like it's nothing!""What normal person could keep killing themselves over and over like this?""And the way he does it—without a trace of hesitation the second he realizes he's trapped!""This isn't just courage. This is something beyond human!"
Watching Tanjiro's relentless self-sacrifice, countless beings across countless worlds were stunned, moved, shaken to their core.
One Piece world.
"This isn't madness," Sengoku said, eyes alight with admiration. "That boy is fighting for ideals, for his unshakable convictions."
"He's risking everything to protect his sister, and to save the two hundred innocent civilians trapped on that train," Garp added with a rare seriousness. "What a remarkable young man!"
"To repeatedly kill yourself for the sake of others… that kind of willpower, that courage—it commands respect," Tsuru said quietly.
"A true hero!" voices echoed among the Marines—Gion, Aokiji, even strategists and officers alike felt a lump in their throats.
Wano, Onigashima.
"Wororororo…"
The drunken Emperor of Beasts, Kaido, covered his eyes with one hand as tears streamed down his face.
"How enviable… someone who can just die whenever he chooses. Unlike me… no matter how many times I try, even leaping from ten thousand meters, I still can't die! What do I have to do to finally end it all…?"
Hunter x Hunter world.
"He's amazing! Seriously amazing!" Gon's eyes sparkled with awe as he stared at Tanjiro.
"Killua, I want to be like him too!"
"You don't fall short of anyone, Gon," Killua replied, though inwardly he saw the resemblance clear as day.
Gon and Tanjiro were the same kind of people—kind to a fault, never giving up, always willing to push themselves to protect others.
Re:Zero world.
"Tanjiro-kun, you're incredible," Subaru whispered, stunned.
He knew better than most how much courage it took to end one's own life. Even after countless deaths and returns, he still couldn't do it without hesitation.
"If he can do that to protect what matters, then I need to find more courage too…"
Summer Time Rendering world.
"My situation's different," Shinpei thought to himself. "Every time I reset, time moves forward. I can't just throw my life away recklessly—I have to be careful, deliberate."
Naruto world.
"He's breaking illusions by killing himself—again and again—and without a shred of confusion or hesitation?" Yamato's jaw nearly hit the floor.
"That's the mark of a true hero," Kakashi murmured.
"But… won't this take a toll? If he keeps doing it, his mind might blur the line between dream and reality…"
Demon Slayer world.
At the Demon Slayer Corps headquarters, the Hashira themselves were left speechless.
"So strong… Tanjiro, you're amazing!" Mitsuri beamed, her eyes sparkling.
"To think he could go this far—how flashy!" Tengen grinned.
"Such kindness, such determination for others. I acknowledge you, young Tanjiro. Namu Amida Butsu." Gyomei pressed his palms together, tears running down his blind eyes.
"Hmph. If he wants to become a Hashira, this is the bare minimum. The ones who can't manage it? Trash." Sanemi scoffed, but deep inside, he too had recognized Tanjiro's worth.
Obanai glanced at Rengoku. "And what about you, Kyojuro? Letting kids take the lead while you're here?"
"Hah! Shameful indeed," Rengoku boomed, voice still thunderous even as he reflected on himself. "To have a boy charge ahead while I hang back—I've disgraced the title of Hashira!"
"Look!" Shinobu's eyes widened.
On the glowing screen before them, Tanjiro leapt high into the air, unleashing a furious strike.
His flowing water-like blade sliced clean through Enmu's neck.
The sight electrified all who watched.Not just the Demon Slayer Corps, but countless people across all worlds erupted in cheers.
And yet—
the very next moment, smiles froze.
For though Enmu's head had been severed by the Nichirin blade…he did not die.
"..."
