In this world, humans also possess special abilities.
To be more precise, humans in this world can make contracts with Devils, and after paying a certain price, they can borrow the Devil's power through the contract to fight.
To ordinary people, those who make contracts with Devils can use various incredible abilities.
Just like the two girls flying in the sky at this moment.
However, Denji was hesitating about their true identities.
Although they looked human, the powers they had displayed so far had already surpassed that of many Devil hunters.
Not just their wind-like speed, but even the entire weather in Tokyo had been completely altered by their presence.
If they were human, what kind of powerful Devil had they made a contract with to obtain this power?
While Denji's mind was in a daze, the voices of the two girls in the sky reached him.
"Hehehe, as expected of my half, this power is not inferior to mine at all."
"Correction, Yuzuru is the half of Wind Spirit Yamai, not Kaguya Yamai's half."
"I am the true Yamai!"
"Mocking, it seems Kaguya Yamai is lacking more than just intelligence, but also self-awareness."
"What?! You dare say that?! Be careful, I might just beat you up!"
"Provocation, if you can do it, try it."
At this moment, visible windstorms surrounded the two girls, lifting sand and dust, swirling around them.
They controlled the wind's power with their hands, constantly compressing it, and soon, two small tornadoes emerged.
Standing in the eye of the wind, the girls' expressions remained unchanged, as if they had long grown accustomed to such an environment.
However, Denji and Power, standing beneath them, were suffering.
Caught between the two tornadoes, it felt like their bodies were being torn apart. Stones whipped up by the wind hit them, leaving bruises on their bodies.
In the middle of the storm, they could only cling tightly to anything nearby to avoid being blown away.
"This is all your fault for wanting to get involved! What are we supposed to do now?!" Power yelled in panic. "In this situation, forget about fighting, we can't even stand still!"
"Tch... I guess we'll have to do this," Denji muttered as he struggled to free one hand from the railing.
He unbuttoned the white shirt of his police uniform, revealing a triangular iron ring on his chest.
As Denji pulled the iron ring, a high-frequency vibrating sound came from his body, as if a motor were hidden inside him.
When the ring was fully pulled, blood splattered.
Denji's head transformed into a massive chainsaw, his orange-yellow eyes flashing like lights. His mouth opened, revealing sharp steel-like teeth.
In addition to that, his arms were cut in half, replaced by rotating chainsaws, making him look bloody and terrifying.
Chainsaw Man.
This was Denji's other identity.
Unlike Devils, who had their human bodies overtaken by Devils, with the Devil's mind and personality dominating, Chainsaw Man, or Weapon Man, was a fusion of human and Devil, but the human consciousness remained dominant, allowing them to retain 100% of their original consciousness while using the powers of the Devil weapon they fused with.
This was an even rarer and stronger existence than a Devil.
"Power, create a ball!" Denji, now in his Chainsaw Man form, shouted as he turned to his partner.
"A ball? What kind of ball?"
"Soccer, basketball, rugby, any ball will do! Make two of them!"
Although Power didn't immediately understand what her partner wanted to do, she still cut her hand, using her blood to form two ping-pong ball-sized blood orbs.
She summoned all her strength to fight the fierce wind and threw the balls to Denji.
"Alright, watch me hit a home run!"
Denji positioned himself and raised his chainsaw, using it like a bat.
"Bang! Bang!"
The steel blades of the chainsaw collided with the blood orbs, and with the power of the Weapon Man transformation, the two blood orbs flew out at bullet-like speeds.
The blood orbs pierced through the layers of the storm, heading straight for the two girls in the center of the tornado.
However, even with the strength of a Weapon Man, a hit strong enough to pierce steel lost its accuracy in the chaotic wind.
The blood orbs veered off course and flew past the girls' eyes.
"How dare you! Who dares to attack us?!"
The two girls in the sky turned their gaze toward the direction of the blood orbs and saw Denji and Power standing on the building.
"I don't like wasting words, so I'll just ask directly," Denji raised his chainsaw and asked straightforwardly, "Are you human or Devils?"
"Heh... not only do you have the courage to interrupt our duel, but you also dare to ask us questions."
The more lively-looking girl of the two responded, "Not bad. I've never met someone like you before. I'll forgive your rudeness this time."
"Answer, we are neither human nor Devil," the other girl said expressionlessly, "We are spirits."
"Spirits... Spirits? What spirits?" Denji froze. "Like the fairies from children's books?"
"I am the Wind Spirit, Yamai Kazamachi. However, before I defeat this imposter, I'll refer to myself as Kaguya Yamai."
"Introduction, I am also a Wind Spirit, Yuzuru Yamai."
Not even caring whether they had answered Denji's question, the girl named Kaguya Yamai's expression grew serious. "Now, it's your turn to answer my question. Why are you trying to stop my sacred duel with Yuzuru?"
"Can you find a place without people to duel?" Denji asked.
"There's no one here," Kaguya Yamai replied.
"Me and Power are not... Well, you do have a point," Denji said, thinking about it.
Before Kaguya Yamai could continue speaking, Yuzuru Yamai slapped the back of her head.
Facing Kaguya Yamai's angry glare, Yuzuru Yamai calmly said, "Criticism, don't cause trouble for others."
"If anyone caused trouble, it was you!" Kaguya Yamai snapped back.
"But Yuzuru said from the beginning not to fight near human cities. You didn't listen."
"Well..."
Kaguya Yamai looked away awkwardly but still stubbornly said, "Although it's a human city, there really weren't any people around."
"That's because we scared everyone away," Yuzuru Yamai said, looking at Denji and Power with a slightly apologetic look. "This is our fault, please accept our apologies."
"Well... as long as you know your mistake," Denji scratched his head awkwardly, clearly not used to such a polite Devil.
"Heh, since you've apologized, there's no need for me to apologize!" Kaguya Yamai immediately returned to her energetic self. "Now, for our next contest, let's see who can fly to the Western continent first!"
"Mocking, did you forget who lost last time in the speed contest?"
"I didn't lose! It was a tie!"
"Correction, Kaguya Yamai was 0.3 seconds slower than Yuzuru."
"Then let's see who's faster this time!"
"As you wish."
The two girls spoke among themselves as powerful wind currents began to swirl around them again.
"Wait—!"
Denji tried to stop them, but before he could speak, the wind pressure from their takeoff left him speechless.
In the blink of an eye, they shot off like arrows through the clouds, disappearing from sight.
The wind-like girls came like the wind, and left like the wind.
Only Denji and Power stood there, staring at each other.
