The Six Eyes had seen the microscopic shifts in Ren's physiology the millisecond the chalk left Gojo's fingers.
Ren's breathing hadn't spiked. His heart rate hadn't fluttered. Instead, his center of gravity flawlessly and instantaneously dropped.
His weight shifted to the balls of his feet with absolute, perfect balance. He tilted his head exactly two inches to the right—not an inch more, not an inch less—allowing the chalk to harmlessly breeze past his ear.
It was a minimalist, hyper-efficient evasion. Zero wasted motion. Absolute perfection.
That's not raw strength, Gojo deduced, his brilliant blue eyes narrowing beneath the blindfold.
That is instinct.
And much better than that of maki's
That is muscle memory drilled into the bone over thousands of hours of life-or-death combat.
More specifically... that looked exactly like the Zen'in clan's close-quarters evasion footwork.
Gojo leaned his shoulder against the doorframe, letting out a low, genuinely bewildered hum.
The "intimacy transfer" theory he had spouted earlier was, of course, complete garbage. He had thrown it out purely to fluster Maki and confirm they were sleeping together. But even playing devil's advocate—even if he entertained the profoundly absurd idea that some freak biological exchange had triggered a latent mutation in Ren's DNA to match Maki's muscle density—it still left a glaring, impossible plot hole.
You cannot sexually transmit martial arts mastery and instinct.
"What exactly are you, Ren-kun?" Gojo whispered to the empty courtyard.
The mechanics of a Heavenly Restriction were absolute. It wasn't a cursed technique you could learn, nor was it a sickness you could catch.
It was an involuntary, binding vow placed upon a sorcerer's body at the exact moment of their birth. It was the universe enforcing an 'equivalent exchange' to maintain natural balance.
For Toji Fushiguro, and now Maki, the universe stripped away their cursed energy in exchange for a body that broke the laws of physics.
Ren was a normal teenager. He had a normal civilian life. He wasn't born with a restriction. The Six Eyes confirmed that Ren's cursed energy levels were currently sitting at that same near-zero, civilian-squashed threshold as Maki's.
So how in the world did his soul suddenly bypass the laws of equivalent exchange? What was the catalyst?
If Ren possessed some kind of hidden, reality-warping Cursed Technique that allowed him to copy abilities, the Six Eyes would see the spark of that technique carved into his brain. But there was nothing. No technique.
No foreign cursed energy. Just a flawlessly replicated Heavenly Restriction and the battle-hardened reflexes of a seasoned killer.
Gojo pushed off the doorframe, a slow smirk curling the corners of his mouth.
...
The winding, open-air corridors of Tokyo Jujutsu High were quiet, save for the rhythmic crunch of gravel beneath their boots.
Maki walked a half-step ahead of Ren, the rigid tension slowly returning to her shoulders as they approached the student dormitories.
Suddenly, she stopped, turning on her heel to face him.
"Listen to me," Maki said, her voice dropping into a fierce, commanding whisper. She grabbed him by the front of his denim jacket, pulling him in close so her voice wouldn't carry across the courtyard. "When we go in there, we are just acquaintances. You are a new transfer student. That is it."
Ren raised an eyebrow, a slow, teasing smirk pulling at the corner of his mouth. "You're breaking up with me already, boss? I haven't even seen my room yet."
"I am serious, Ren," she hissed, though a faint pink dusted her cheeks. She tightened her grip on his jacket. "You don't know my classmates. Panda has no concept of boundaries, Toge will just egg him on, and the first-years... Nobara is an absolute menace. If they find out we're dating—let alone how you supposedly got your strength—they will never, ever let me live it down. It's a nightmare."
Ren's smirk softened into a genuine, reassuring smile. He reached up, gently resting his hands over hers where they gripped his jacket.
"I get it," Ren murmured softly. "Cold, distant, and completely professional. I'm just the clueless new guy. Your secret is safe with me."
Maki let out a long, heavy exhale, her grip loosening. "Good. Don't do anything stupid."
She let go of him, cleared her throat to rebuild her tough, uncompromising exterior, and turned the corner into the main student common area.
Ren followed right behind her, stepping into the sunlit courtyard.
It wasn't empty.
Sitting on the wooden steps of the dorms were three very distinct figures. A tall, spiky-haired boy with a permanent scowl was tossing a cursed tool back and forth in his hands. Next to him sat a boy with his lower face completely hidden by a high collar.
And standing a few feet away, aggressively complaining about the lack of good vending machine options on campus, was a girl with short orange hair.
Megumi Fushiguro. Toge Inumaki. Nobara Kugisaki.
"Maki!" Nobara called out, her annoyance instantly vanishing as she spotted her upperclassman.
"Where have you been? Panda said you went to Shinjuku to fix your—"
Nobara stopped dead.
Her brown eyes locked onto the tall, dark-haired boy stepping out from behind Maki. The aggressive, confident posture she always carried completely went cold. Her jaw actually dropped.
Ren instantly recognized her. He kept his expression perfectly blank, slipping flawlessly into his customer-service persona, though internally, he was bracing for an absolute disaster.
Megumi stopped tossing his weapon, his dark eyes narrowing analytically as he took in Ren's relaxed, civilian-like posture. Toge tilted his head. "Kelp?"
"Everyone, shut up," Maki announced loudly, taking command of the space with her usual bossy authority. She gestured stiffly toward Ren. "This is Ren. He's... a special transfer student. He's going to be staying in the second-year dorms starting today."
Nobara's finger shot out, pointing directly at Ren's face. Her face flushed a brilliant, violent pink, caught halfway between sheer embarrassment and explosive outrage.
"You!" Nobara sputtered, her voice cracking an octave higher than normal. "You're the—the retail guy! From the boutique!"
