The battle officially began.
Facing the pouring rain of Rabbit Hair Needles falling from the sky, Makoto, now equipped with Madara's Rinnegan, directly used the Rinnegan's signature technique.
"Shinra Tensei."
With his body as the center, a visible ring of repulsive force exploded in all directions, condensing into an invisible wall half a meter in front of him.
The Rabbit Hair Needles collided with it, like moths flying into a flame, bouncing off with a series of crisp 'clink clink' sounds.
Makoto didn't pause.
A grey-black Susanoo skeleton rose from his body surface, enveloping him entirely.
Dozens of colossal meteorites appeared in the sky, trailing crimson tails as they fell, turning half the sky into a sea of fire.
This was another of Madara's signature techniques: Tengai Shinsei.
Otsutsuki Kaguya slightly raised her gaze, those flawless white eyes reflecting the falling fireballs.
She raised both palms, the skin in the center of her palms splitting open, white bone needles emerging from the cracks.
Just as she was about to shoot the bone needles at the meteorites in the sky, Black Zetsu poked half his body out from her sleeve and said urgently: "Mother, don't ignore what's below. He's using this technique to distract you."
Makoto had already used this move against Six Paths Madara earlier. Black Zetsu wasn't about to let his mother fall for the same trick.
Otsutsuki Kaguya's white eyes lowered slightly, her gaze shifting from the meteorites to the battlefield below.
Makoto was no longer where he had been.
That ant had leapt into the air while pulling the strange cord on his chest, transforming into a monster with chainsaws growing from both arms and head, rushing towards her like a high-speed train.
The bone needles in Otsutsuki Kaguya's palms continued to shoot towards the meteorites in the sky.
"All-Killing Ash Bones."
The white bone needles detached from her palms, their speed more than ten times faster than the Rabbit Hair Needles.
The moment a bone needle hit the first meteorite, that mountain-sized colossal rock silently vanished, turning into grey-white dust floating in the air.
In less than three seconds, all the meteorites were almost simultaneously pierced by the grey-white bone needles, turning into sky-filling dust.
All-Killing Ash Bones was one of Otsutsuki Kaguya's deadliest techniques.
Even a Complete Body Susanoo would be instantly crushed if hit by this technique, so its power spoke for itself.
And thanks to Black Zetsu's warning, Otsutsuki Kaguya was well prepared.
Facing the slash from Makoto in Chainsaw Man form, she didn't even turn around. A black crack suddenly split open in the space behind her... Yomotsu Hirasaka!
Otsutsuki Kaguya's body instantly vanished into the portal behind her, causing Makoto to swing at nothing.
Almost at the same instant, an identical crack split open in the space behind Makoto.
Otsutsuki Kaguya emerged from it with her upper body, raised her hand, the bone needle in her palm already breaking through the skin, aiming at the back of Makoto's head.
"All-Killing Ash Bones."
The bone needle shot from her palm, less than half an arm's length from the back of Makoto's head.
"Pfft."
The white bone needle pierced through the back of Makoto's head, exiting through his forehead, carrying away specks of grey-white powder.
Makoto's body stiffened. The next second, his head began to burn and shrink rapidly, like a lit cigarette.
Otsutsuki Kaguya said coldly, "Dealt with."
She withdrew her hand and was about to turn around to recover the Nine-Tails from Naruto's body.
But Black Zetsu in her sleeve couldn't smile at all.
Those dot eyes were fixed intently on Makoto's disintegrating body, his pupils full of vigilance.
From his understanding of Makoto, this lecherous bastard shouldn't be dealt with so easily.
The next moment, Black Zetsu saw that although Makoto's head was still disintegrating, his body was still capable of acting.
His right hand suddenly raised, using the chainsaw to abruptly slice open his own chest.
Black Zetsu's pupils contracted sharply.
He remembered the way Makoto had dealt with Six Paths Madara earlier.
The chainsaw's blade cut through the sternum, revealing the still-beating heart inside the chest cavity.
It was like an orange-red puppy's heart... it was Pochita!
That heart jumped out of the chest crack, stepped onto the shoulder that was gradually turning to ash, and leaped towards Otsutsuki Kaguya's face.
Otsutsuki Kaguya instinctively leaned her head back, but it was too close.
That heart was less than a palm's width from her face. It expanded, deformed, and grew in mid-air.
In less than half a second…
An arm extended from the heart, five fingers spread wide, grabbing Otsutsuki Kaguya's face.
A second arm extended from the other side of the heart, locking onto Otsutsuki Kaguya's shoulder.
The neck, head, and other parts grew out one after another, grinning with a mouth full of sharp fangs.
The whole body was pitch black.
Around the neck was a scarf woven from intestines, slowly wriggling in the night wind like a living creature.
Black Chainsaw Man form!
Makoto had completed his full transformation.
"It's been a long time since I've taken this form."
His four arms simultaneously exerted force, pulling Otsutsuki Kaguya's body forward.
Otsutsuki Kaguya's feet gouged two deep trenches in the ground, mud and broken stones flying from her heels.
For the first time, panic appeared in Otsutsuki Kaguya's white eyes.
She struggled, trying to use Amenominaka to escape. The spatial crack behind her had just begun to open when Makoto tilted his head and swung the chainsaw on his head towards that crack.
"Crack."
He split the spatial crack in two with the chainsaw. The black spatial fault line split apart in the middle, like a piece of paper torn in half, tearing space apart with pure physical strength!
At the critical moment, the ground suddenly came alive.
The ground beneath Makoto's feet bulged, countless stone spikes growing forth, stabbing towards him simultaneously from all directions.
The tips of the stone spikes were sharper than weapons, piercing through his calves, thighs, waist, abdomen, and arms, pinning him in place.
Hundreds of stone spikes densely covered his body, like a spiky sea urchin.
Black Chainsaw Man Makoto looked down at the stone spikes piercing his body, his movement forced to a halt.
The tips of the stone spikes had penetrated his skin and muscle, getting stuck in the gaps between his bones. Although they didn't cause fatal wounds, they did slow him down.
His chainsaw was only a hair's breadth from Otsutsuki Kaguya's neck, but after being caught by the stone spikes, it could no longer advance even half a point.
Otsutsuki Kaguya took this opportunity to break free from Makoto's grasp. The spatial crack behind her reopened, and her entire body leaned back, vanishing into the black crack.
Makoto looked up at the surrounding terrain.
This land had completely changed.
Originally a barren wasteland from the previous battles, it was now covered with stone spikes, as dense as a needle mountain.
'Nature Integration?'
Makoto, with his god's-eye view, of course knew this was one of Otsutsuki Kaguya's abilities.
Assimilating her own Chakra with the earth, controlling the terrain at will.
It was similar to the Inorganic Reincarnation used by Sage Mode Kabuto in the original work, but the power and scale were on a completely different level.
Black Chainsaw Man's whole body shuddered.
The hundreds of stone spikes stuck in his body were simultaneously shattered into pieces.
