At the break of dawn.
On the desolate wilderness.
A battle surpassing human limits was nearing its final conclusion.
Facing the infinitely regenerating demon alone, Kyojuro Rengoku still did not retreat a single step.
Despite the demon's threats and temptations, Kyojuro Rengoku remained steadfast.
The integrity of a Pillar was perfectly displayed at this moment.
Even though he was covered in wounds, he remained resolute and charged forward without hesitation.
Burn Your Heart!!!
Surpass Your Limits!!!
A powerful fighting spirit, like a raging inferno, erupted from Kyojuro Rengoku's battered body, burning fiercely.
"To have such spirit despite being gravely wounded, hahaha, you really should become a demon, Kyojuro! And fight with me forever!"
Akaza let out an excited, wild laugh.
"I am Flame Pillar — Kyojuro Rengoku!!!"
Kyojuro Rengoku let out his final roar.
Boom!
The ground beneath his feet exploded.
A giant flame dragon enveloped his body, charging straight towards the Upper Rank demon, unstoppable.
Flame Breathing Esoteric Art — Ninth Form — Rengoku!!!"
"Come on, Kyojuro!"
Akaza did not dodge, showing no fear.
"Destructive Kill — Annihilation Style!!!"
Boom!!!
Akaza shattered the exploding flame dragon head with his bare hands.
Rumble!
A terrifying explosion followed, with flames soaring into the sky.
Within the fiercely burning flame tornado, demon blood continuously splattered.
Flame Pillar Kyojuro Rengoku's Nichirin Blade pierced through and sliced open Akaza's body.
However, it still failed to sever his neck, only embedding itself.
In contrast, Akaza's heavy punches could easily inflict severe damage upon him.
Watching as the terrifying demon's fist was about to pierce Akaza's chest.
Just then.
Clang ~ Buzz ~
A clear sword hum sounded.
"Flower Breathing"
A beautiful figure descended from the sky, plunging into the flame tornado battlefield, piercing Akaza's fist with a single strike and pinning his hand to the ground.
This sudden turn of events startled everyone present.
"What happened? What happened?!"
Inosuke, the boar-headed youth watching from the sidelines, unable to intervene, shouted repeatedly.
"Someone seems to have fallen from the sky!"
Tanjiro stared blankly upwards, then his eyes suddenly widened.
Because he saw it: a ship flying in the night sky!!!
"Is it reinforcements? Has another Pillar come to help?"
Zenitsu Agatsuma said excitedly.
At this very moment.
The most, most, most shocked by this unexpected situation was Flame Pillar Kyojuro Rengoku.
Even with only one eye remaining, he still recognized the girl who had descended from the sky and saved him from certain death.
"Shin... no, you are Kanae!!!"
Flame Pillar Kyojuro Rengoku's sole eye suddenly widened.
He still clearly remembered that morning several years ago.
The girl named Shinobu cried uncontrollably on the ruined battlefield.
Because her older sister, their comrade, Flower Pillar Butterfly Kanae, also one of the Nine Pillars, had gone missing.
Though it was called a disappearance, everyone actually knew what had happened.
Flower Pillar Butterfly Kanae had died in battle against a demon.
And her remains had probably already entered the demon's belly.
Although it was heartbreaking, in the Demon Slayer Corps, this was a common occurrence.
Even a Pillar would face the risk of dying in battle.
Gradually, everyone accepted this fact.
However...
Now.
At this very moment.
A miraculous thing had happened.
Flower Pillar Butterfly Kanae, who had been missing for several years, had suddenly appeared alive.
For a moment, Flame Pillar Kyojuro Rengoku was completely stunned.
"Kyojuro Rengoku, now is not the time to be distracted! Quickly slay the demon!" Flower Pillar Butterfly Kanae called out to remind him.
"Yes!!!" Hearing this, Kyojuro Rengoku finally snapped back to reality, realizing that the most urgent task was to slay the demon.
Hooaaahhh!!!
The fiery Nichirin Blade advanced inch by inch towards Upper Moon Three Akaza's neck.
"Damn it! There's still backup! But... it's all futile!" Akaza's face suddenly darkened.
The next second.
He suddenly exerted force.
The powerful shockwave pushed Kyojuro Rengoku and Butterfly Kanae backward.
Seizing this opportunity, Akaza took a huge leap backward.
In the blink of an eye, all the wounds on his body healed as if new.
Akaza looked at the eastern horizon; there was only a little time left until sunrise, but it was enough for him to kill everyone present.
Just as Akaza unleashed his Blood Demon Art, preparing to launch another fierce attack.
The next second, without warning.
An extremely terrifying pressure descended from the sky.
Even a powerful Upper Moon collapsed without any resistance.
"Is this a demon?" Kanna stood on Akaza's back, poking Akaza curiously with her chubby finger.
