### Chapter 15: It's Only a Rivalry If Strengths Are Equal
"It's really lively here."
"Huh? Who's there!"
The sudden voice startled Vayer.
He narrowed his eyes like a cold snake flicking its tongue, quickly scanning the surroundings, searching for the owner of the voice.
Soon, he discovered the figure of a black-haired young man standing on the flat roof of a building by the roadside.
"A girl who can affect the structure of the Jujutsu world, and someone named Tengen..."
"Since things are so interesting, why not count me in?"
Ryota stood at the edge of the roof with his hands in his pockets, looking down at the group below with a condescending gaze, his expression tinged with interest.
Due to the angle of the morning sun in the sky, Ryota's figure cast a shadow.
It happened to cover the despairing Amanai Riko.
"You, it's you!"
Amanai Riko's eyes widened slightly, staring blankly at the black-haired young man she had seen in the restaurant earlier.
"Is he someone sent by that side to protect Young Lady?"
Clutching her injured right arm, Kuroi Misato looked up at Ryota standing on the roof with hands in his pockets, and couldn't help but ask.
"Someone from Jujutsu High?"
Noticing Amanai Riko and Kuroi Misato's reactions, Vayer stared vigilantly at Ryota, while quietly gathering Cursed Energy in his hands.
"Jujutsu High? I'm not with them."
"I don't belong to any faction, and no faction is qualified for me to join."
Ryota's mouth curled up in a disdainful arc.
As a transmigrator who awakened a System upon arriving in this world and unlocked the [Uchiha Madara · Rinnegan] template.
Combined with the will and arrogance of a powerhouse honed through experiencing that perspective.
It was destined that he could not submit to anyone or join any faction.
Even the most famous and orthodox Jujutsu High in the current world didn't have that qualification!
"So he's just a fledgling brat."
Hearing Ryota's words, Vayer sneered, actually lowering his guard.
Even as a group of Curse Users, they had to acknowledge the strength of Jujutsu High.
Especially since the [Six Eyes], which only appeared once every few hundred years, had also enrolled and joined them.
Even their Curse User group had to be wary of Jujutsu High.
In his eyes, the suddenly appearing Ryota had gone from an intruder with unknown motives and strength to a brat who only knew how to talk big.
"He's not from that side..."
Kuroi Misato's heart tightened.
Ryota wasn't angered by Vayer's attitude.
He didn't even show the slightest ripple of reaction to the other party's response.
With a flash of his figure, before anyone could react, he appeared right in front of Vayer.
Tilting his face up slightly, he looked down at the latter, revealing a wildly arrogant smile.
"Whether I'm a fledgling or not, do you want to test it with your life?"
"How is this possible?!"
Vayer's narrowed eyes widened into circles, his body taking a step back, his face full of disbelief.
Clearly just a brat who hadn't seen the world and was wet behind the ears.
How could he possess speed that blurred his vision and left him unable to react?!
Not far away, Kokun also looked shocked, because like Vayer, he hadn't noticed Ryota's movement either!
His gaze became grave as he rubbed his white-gloved hands.
"Who exactly are you, and are you here for the Star Plasma Vessel too?"
"Star Plasma Vessel, that's what you call this girl, right?"
Hearing this, Ryota glanced at Amanai Riko, who was sitting on the ground beside him, and then said casually:
"That's right, I do have some interest in her."
When he was facing Fushiguro Toji in the restaurant, he noticed Amanai Riko entering the door.
He sensed a trace of strangeness from the girl.
This also piqued his interest in Amanai Riko.
"Is Your Excellency also after the Star Plasma Vessel's life? If so, our goals are aligned, and there's no need for conflict."
Kokun was the more rational and cautious type.
Having witnessed Ryota's ghostly speed, he didn't want complications when they were about to kill the Star Plasma Vessel.
"Listening to what you just said, if this girl dies, it will affect that person named Tengen, and thus overturn the entire Jujutsu world."
"But unfortunately, what I'm interested in isn't overturning the Jujutsu world."
For Ryota, overturning the Jujutsu world was something he didn't need to achieve by killing a single person if he wanted to do it.
Ryota disdained such petty means.
Moreover, the target was an ordinary girl with no ability to resist.
From their conversation earlier, Ryota also roughly understood the power dynamics. The strangeness he sensed from Amanai Riko likely came from that Tengen.
"So, Your Excellency insists on opposing me?"
Kokun stared at Ryota.
Ryota had become mysterious in his eyes, but he was only somewhat wary, not afraid or retreating.
"Opposing? Hahahaha—"
Facing the serious Kokun, Ryota threw his head back and laughed loudly.
That unrestrained laughter, as if no person or thing could bind him, made Ryota filled with madness at this moment.
But seeing this scene, Vayer and Kokun both simultaneously felt a sense of being despised from the bottom of their hearts.
Just like how they hadn't put Kuroi Misato and Amanai Riko in their eyes earlier...
No! Even more than that level!
Anger instantly filled their chests.
Just as they decided to stop talking and attack directly to tear this fast brat to pieces.
The laughter echoing through the alley stopped abruptly.
Ryota's expression was indifferent, like a deep, distant pool.
He slowly opened his eyes.
Crimson pupils, with three clearly visible tomoe within them.
An aura of weirdness and ominousness instantly swept out from the pupils of these eyes that reflected the soul.
"It seems you've misunderstood one thing..."
A breeze blew Ryota's black hair.
As his bangs swayed in front of his forehead, those crimson Three-Tomoe Sharingan reflected the figures of Vayer and Kokun.
"It can only be called a 'rivalry' when the strength of both sides is equal."
