Chapter Text
The cafeteria at Blue Lock wasn’t known for peace. Laughter, insults, and the constant clatter of trays formed a soundtrack to every mealtime.
Isagi Yoichi sat near the corner, trying to focus on his curry before his next practice session. Bachira had wandered off somewhere with Chigiri, and for once, there was no one beside him filling the silence with chatter.
That silence didn’t last long.
“Isagi Yoichi,” a low voice said, deliberate and unhurried, as if tasting each syllable.
Isagi looked up. Across the table stood Himizu Aiki—the forward with a predator’s eyes and the unnerving smile that made even confident players shift uneasily.
“…Himizu,” Isagi said carefully.
“Sit with me,” Aiki said. Not a question. A statement. His tray clattered onto the table, directly across from Isagi’s, and he leaned forward with the casual arrogance of someone who didn’t believe in hesitation.
Isagi had seen Aiki play—his ruthless precision in the scrimmages, his uncanny ability to unnerve defenders. He wasn’t as loud as Barou or as flamboyant as Bachira, but there was a sharpness to him, a stillness before the strike that reminded Isagi of a coiled knife.
“Uh. Sure,” Isagi muttered.
They ate in silence for a moment, but Aiki’s gaze was fixed—not on his food, but directly on Isagi. It wasn’t subtle.
“…Do I have something on my face?” Isagi asked finally.
“No,” Aiki said. He smirked. “I’m just thinking. You look… ordinary. But you’re not. I can’t stop wondering why.”
Isagi stiffened. He knew the type. Ever since his plays during Team Z and beyond, people had been looking at him differently. Admiration, jealousy, curiosity—they all mixed together. But Aiki’s stare wasn’t admiration. It was something heavier.
“Ordinary doesn’t win games,” Isagi said simply, returning to his food.
“Exactly.” Aiki leaned closer, eyes glinting. “That’s why I want to know what’s inside you. How do you keep doing it? How do you make everyone else play your game?”
The obsession in Aiki’s tone made Isagi shift. He didn’t answer immediately. Instead, he finished his bite, wiped his mouth, and looked back.
“…If you’re asking me that,” Isagi said, “then you already lost. You’re trying to play my game instead of yours.”
For a moment, silence. Then Aiki’s grin widened, sharp and delighted.
“Good answer,” he murmured. “Better than I hoped.”
~✾~~⋇⋆✦⋆⋇~~✾~
That was how it started.
Not with a clash of goals. Not with a fiery rivalry. But with Aiki deciding—quietly, firmly—that Isagi Yoichi was someone he wanted to understand, maybe even possess in his own way.
And Isagi, despite himself, didn’t walk away.
~✾~~⋇⋆✦⋆⋇~~✾~
It was supposed to be a routine practice: movement drills, possession battles, short-field scrimmages. But Isagi noticed Aiki trailing him more than once, matching his runs, shadowing his cuts, testing how closely he could mimic his pace.
By the third time, Isagi spun on him.
“What are you doing?”
Aiki tilted his head, sweat slicking back his grey hair. “Studying.”
“Studying me?”
“Mm. If I learn your rhythm, maybe I can break it. Or maybe…” His smile edged into something unreadable. “Maybe I’ll learn how to move with you.”
Isagi scowled, but there was no real malice. He’d dealt with Barou’s ego, Rin’s cold precision, Kaiser’s suffocating aura. Aiki’s fixation felt different—not one of superiority, but of fascination.
“…Do what you want,” Isagi muttered. “But if you’re in my way during the scrimmage, I’ll crush you.”
Aiki chuckled, a low sound. “That’s what I like about you.”
~✾~~⋇⋆✦⋆⋇~~✾~
The scrimmage began. And just like that, Aiki wasn’t a shadow anymore. He was a mirror. Every time Isagi cut left, Aiki anticipated. When Isagi pivoted for space, Aiki slid into it seamlessly. It was disorienting—like playing against someone who had studied his replay tapes for hours.
But then Isagi adapted.
He shifted his timing, feinted one beat earlier, baited Aiki into overcommitting—and used him as a decoy to open the pass to Hiori.
Goal.
Aiki laughed, clapping his hands once, loudly. “Beautiful! You used me like I was part of your plan.”
“Because you were,” Isagi shot back, panting.
The grin Aiki gave him wasn’t disappointment. It was something more dangerous. Satisfaction.
“You really are dangerous, Isagi Yoichi.”
~✾~~⋇⋆✦⋆⋇~~✾~
That night, Isagi lay in bed staring at the ceiling. He should have been exhausted, but Aiki’s words lingered.
Dangerous.
Not just a rival, not just another ego. Aiki wanted to unravel him—to take him apart and see what made him tick.
And Isagi, against his better judgment, found himself wondering what it would be like to let him try.
~✾~~⋇⋆✦⋆⋇~~✾~
The training center emptied late at night. Most players crashed as soon as curfew passed, the exhaustion of drills and matches pulling them into dreamless sleep.
But Isagi couldn’t sleep. His mind replayed scenarios—the near misses, the perfect passes that could have been sharper, the way Kaiser had smirked that day when Isagi lost the ball for a fraction too long.
He slipped out of his room, ball tucked under his arm, and padded barefoot into the smaller auxiliary pitch. The fluorescent lights buzzed overhead. The space smelled faintly of rubber turf and detergent.
He wasn’t alone.
A figure was already there, sitting cross-legged on the ground, watching the goal as if it were a beast in a cage. The pale glow caught his profile. Himizu Aiki.
“…Of course,” Isagi muttered.
Aiki turned, that same wolfish half-smile curling at his lips. “I thought you might come.”
“You were waiting?”
“Call it instinct.” He stood, dusting off his shorts. “Couldn’t sleep. You?”
“Same.”
They didn’t speak after that. Instead, they set the ball down and began passing. Short touches at first, then longer drives. Aiki’s control was sharper than Isagi expected—his first touches clean, his returns precise.
“Why do you play like that?” Aiki asked suddenly, trapping the ball under his sole.
“Like what?”
“Like you’re willing to vanish. You make other players the star of the moment, just to win. Most forwards want the spotlight.”
Isagi met his eyes. “The spotlight doesn’t matter. Only the goal does.”
Aiki tilted his head, fascinated. “That’s why I can’t stop watching you.”
The words landed heavier than Isagi liked. He cleared his throat and gestured toward the net. “Less talking. More shooting.”
They took turns. Isagi’s strikes were angled for precision corners; Aiki’s were sharp, violent, and designed to break through keepers by sheer brutality. Different styles, but each shot rang through the empty hall with the same echoing thunk.
When they finally collapsed onto the turf, sweat-soaked and breathless, silence stretched again.
“Yoichi,” Aiki said quietly, as if testing the weight of the name. “If I learn to see the field like you… If I learn to think like you… Would I become you?”
Isagi turned his head. In the pale gym light, Aiki’s eyes glimmered with something unnervingly intense.
“…No,” Isagi said firmly. “You’d just be you. Playing my game won’t make you me. It’ll just make you late to your own goal.”
Aiki laughed softly, closing his eyes. “That’s what makes you terrifying.”
~✾~~⋇⋆✦⋆⋇~~✾~
Blue Lock was merciless about mixing teams for scrimmages. That morning, Ego announced a new rotation: Isagi and Aiki were placed on opposite sides of the field.
The instant the whistle blew, Aiki was on him.
Not like Rin’s suffocating pressure or Barou’s bulldozing force. Aiki’s defense felt like a hunter toying with prey—cutting angles, letting Isagi think he had space, then shutting it down a beat too soon.
But Isagi adjusted. He always adjusted.
Midway through the first half, Isagi baited Aiki into a lunge, drew him out of position, and slid a pass to Kurona that split the defense.
Goal.
The field roared. Isagi’s teammates cheered. But Aiki’s grin only widened.
“You set me up,” he called across the pitch.
“That’s the point,” Isagi shot back.
Aiki’s laugh was sharp, almost delighted. “Good. Do it again.”
From then on, their battle wasn’t about goals. It was about control. Each time Isagi tried to dictate the field, Aiki disrupted it, forcing him to think faster. Each time Aiki shadowed too closely, Isagi used him as leverage.
By the end, neither cared which team had won. What lingered was the exhilaration of sharpening themselves against the other—obsession mirrored in different directions.
~✾~~⋇⋆✦⋆⋇~~✾~
That evening, Bachira cornered Isagi in the hallway.
“Yoichi~,” he sang. “You’ve been hanging around Himizu a lot.”
“So?”
Bachira leaned in close, eyes gleaming with mischief. “Careful. That guy looks at you the way Rin looks at a puzzle he wants to solve. Creepy but kinda fun, right?”
Isagi groaned. “Not this again. First Rin, then Barou, then Kaiser—now Himizu too?”
Bachira laughed, ruffling Isagi’s hair. “Face it, Yoichi. You’re addictive.”
Isagi shoved him off, but he couldn’t shake the words. Addictive. He thought of Aiki’s eyes on him in the empty training hall. The way Aiki mirrored his movements as if carving them into memory.
It wasn’t rivalry alone. It was something else. A strange new friendship, sharp-edged and uneasy, but real.
~✾~~⋇⋆✦⋆⋇~~✾~
Days later, another late-night practice brought them side by side once again. They didn’t speak much. Words weren’t needed. The ball carried everything—the weight of obsession, challenge, and reluctant camaraderie.
Finally, after a long volley, Aiki stopped the ball under his foot.
“…Yoichi. When I watch you play, I feel like I’m disappearing.”
Isagi blinked. “Disappearing?”
“You take the air out of the field. You make everyone else’s vision smaller. But instead of hating it, I…” His voice dipped. “I want to see more. To get closer. Even if it burns me.”
Isagi didn’t answer right away. He looked at Aiki—really looked. Saw the hunger, the fixation, but also the loneliness hiding under it.
“…Then don’t disappear,” Isagi said softly. “Use me to find your own vision. Not mine.”
Aiki exhaled, a sound between a laugh and a sigh. “You always ruin my lines.”
They both laughed then—low, tired, but genuine.
And in that laugh, their rivalry tilted. Not enemies. Not yet full friends. Something more complicated. Something fragile.
Something that might matter, behind the goals and egos of Blue Lock.
~✾~~⋇⋆✦⋆⋇~~✾~
No one else saw those late-night practices. No one else heard the conversations in half-lit gyms. To the others, Isagi and Aiki were just rivals who sharpened each other in scrimmages.
But beneath that, a quiet bond had taken root.
Aiki's obsession didn't fade; it deepened, like a shadow that constantly followed Isagi. Despite himself, Isagi didn't try to push it away.
In Aiki's fixation, Isagi recognized a reflection of his own hunger: the need to chase, to understand, and to reach the "next level" at any cost.
And maybe, in the strange crucible of Blue Lock, that was the closest thing to friendship they’d ever get.
