The mountain air surrounding the Tokyo Metropolitan Curse Technical College was thin, carrying the scent of ancient cedar and damp earth.
For most, this was a place of oppressive history and the smell of death, but as Kaito Sora walked alongside Gojo Satoru toward the student dormitories, he saw it differently. To him, the campus was a grid of structural vulnerabilities and ancient, layering barriers that pulsed like a slow, rhythmic heart.
Gojo remarked that he was making that "creepy face" again—the one where he looked like he was dissecting the bones of the world—but Kaito didn't look away from the horizon. He told the teacher that it was hard to ignore the flaws when the geometry was this messy.
Gojo simply chuckled, his blindfold tilting as he joked about Tengen being heartbroken, before warning Kaito not to knock down any walls on his first day because of the paperwork.
They arrived at the dormitory wing, a stark, functional building that housed the few teenagers tasked with the world's most dangerous burden. As they entered the common area, the atmosphere shifted. The air was thick with the scent of cheap ramen and the low hum of a television.
Gojo's voice boomed, shattering the quiet as he called for Megumi and Yuji to meet their new roommate. A door down the hall slid open, and two figures emerged. Yuji Itadori, with his pinkish hair and wide, energetic eyes, looked like a golden retriever in human form.
Beside him, Megumi Fushiguro stood with his dark hair spiked and his expression hooded with a permanent layer of guarded stoicism. Both of them froze the moment they saw the man standing next to Gojo.
Kaito Sora was a physical impossibility. At 193 centimeters, he loomed over everyone in the room, his 6'4 frame nearly brushing the top of the doorframe. His blonde hair caught the dim light of the hallway like spun gold, and his storm-grey eyes possessed a depth that made it feel as though he were looking through them rather than at them.
He wore a simple, high-collared black shirt that stretched across his broad shoulders, radiating a sense of absolute, polished perfection. Yuji's jaw literally dropped, asking if Gojo had recruited a movie star, while Megumi remained silent, his hand instinctively twitching. His Shikigami instincts were screaming; to Megumi's eyes, Kaito was a void, but the physical pressure he exerted felt like standing at the foot of a mountain.
Kaito stepped forward, his movement so fluid it didn't seem to displace the air. He introduced himself, his baritone voice grounding the room, and noted he was looking forward to seeing how they handled the mess of the world.
Yuji bounced forward, seemingly immune to the intimidation, and immediately began firing off questions about Kaito's height and workout routine. Kaito offered an almost imperceptible smirk, stating he mostly just focused on balance.
In that moment, a System notification flared in his mind, acknowledging the convergence of the trio and prompting a Sign-In. Upon his mental command, Kaito felt his Observation Haki evolve into an advanced stage. The world suddenly expanded; he could hear the "breath" of the wooden floorboards, the rhythmic thrum of the refrigerator, and the jagged, nervous heartbeat of Megumi Fushiguro.
Gojo interrupted the introductions by clapping his hands, announcing that they had one more stop in Harajuku to pick up their third teammate. Harajuku was a sensory overload of neon and noise, and as the group walked through the crowded streets, the "Kaito Effect" was in full swing. Passersby—mostly young women—were stopping mid-stride, phones coming out instantly.
The sight of Gojo and Kaito walking together was a lethal combination of aesthetics that the streets of Tokyo weren't prepared for. They found Nobara Kugisaki standing by a locker station, looking intensely judgmental. She started to snap at Gojo for being late, but her voice died in her throat as her eyes traveled up the massive frame of Kaito Sora.
For the first time in her life, the girl who feared nothing felt her heart do a violent somersault. Kaito looked like the very essence of the Tokyo dream she had moved here to find, only more sophisticated and powerful.
She quickly tried to hide her flush, pointing a finger at Kaito and asking if he was an escort hired to make the group look better. Kaito looked down at her, his gaze feeling like a high-resolution laser, and remarked that she was the one who thought hammers were a solution for structural problems. Nobara's eye twitched with irritation, but before a fight could break out, Gojo led them toward an abandoned building in Roppongi for their first mission.
The building was a skeletal ruin shrouded in a heavy "Curtain" that turned the afternoon sun into a sickly purple. Gojo instructed Yuji and Nobara to head inside while he stayed back with Megumi and Kaito. Kaito didn't enter immediately; he closed his eyes and used his Haki to feel the building. He told Gojo that the students were walking into a trap, noting that the building's core was compromised and the curse was waiting in the ventilation shafts. When Nobara's scream echoed from within, Kaito didn't wait. He moved into the building with a predatory grace, reaching the second floor just as a Grade 3 curse lunged from the ceiling.
Kaito didn't break his stride. Activating his Structural Integrity technique, he saw the curse as a cluster of vibrating lines and a single red glowing anchor. He didn't punch; he simply tapped the air an inch in front of the curse's core. The sound was like glass shattering.
The curse unraveled, its energy dissipating as if it had never existed. He found Nobara in a narrow hallway, cornered by a bloated curse using a young boy as a shield. Her hands were shaking, unable to strike without hitting the child. Kaito's voice rang out, cold and commanding, telling her to move three inches to the left. The sheer authority in his tone forced her to obey.
Kaito flicked a small stone he had picked up, calculating the vector lines perfectly. The stone whistled past the boy's ear and struck the curse's joint, turning its arm to dust instantly. In the flash of a second, Kaito was there, plucking the child from the monster's grasp and placing a single palm against the curse's chest.
He murmured that its construction was flawed and channeled a pulse of Zero-Point force. The curse collapsed into a singular point of nothingness before vanishing entirely.
The building fell silent. Kaito stood there holding the shivering child with surprising gentleness, his clothes perfectly clean and his blonde hair undisturbed.
He stepped toward Nobara and flicked a stray piece of dust off her shoulder, complimenting her positioning. Nobara felt her face explode into heat and turned away with a huff, claiming she had it under control, but she found herself walking much closer to him as they exited. Outside, Gojo was smiling, his Six Eyes having watched the entire process of mathematical destruction.
Kaito looked up at the rising moon, receiving a notification that he had unlocked the Flash Step technique from the world of Bleach.
The world was messy, but Kaito Sora had just started the long process of redesigning it.
