Su Li sat calmly on a bench with an easy, almost playful smile tugging at his lips, while across the deserted street, Shihouin Yoruichi stood in absolute stillness, her golden eyes sharp with scrutiny, her entire bearing radiating quiet menace as she sized him up with the precision of a predator who'd seen far too many battles to be surprised by anything—until now. Their gazes locked through the silence, a quiet tension vibrating in the air between them, electric and coiled, neither side willing to blink first.

A sudden twitch of her ear broke that stillness; two Shinigami were approaching from behind, their Reiatsu faint and insignificant in strength—harmless on their own—but they weren't the problem, not by a long stretch. The real danger stood casually before her, cloaked not in violence but potential, with chaos simmering just beneath the surface of every subtle ripple of his spiritual pressure—dangerous, unpredictable, and entirely unlike anything she'd prepared for.

Yoruichi understood immediately that lingering any longer risked drawing attention they couldn't afford, especially if Soul Society sensed the anomaly standing before her, because the moment they did, everything Urahara had built, everything they'd hidden, would begin to collapse like wet paper. Kisuke's instructions had been clear—test the boy, feel him out, and then leave. That much was done, and now, with her curiosity bordering on unease, it was time to disappear before the situation spiraled.

She rose with the practiced grace of a panther, prepared to vanish as smoothly as she'd arrived, but not without a final parting shot—sharp, barbed, and laced with disdain—because walking away without reminding him of the distance between them would have felt like conceding ground.

"Hmph. Spineless brat. You call that leadership? You're not even fit to lead the Second Division. Resign while you still can," she said in a clipped, icy voice, turning her back on him without waiting for a reply, disappearing with a whisper of displaced air as she launched into a flash step, landing effortlessly on a nearby rooftop with the same elegance that had made her name legendary.

"Miss Yoruichi! Aren't you forgetting something?" Su Li's voice rang out behind her, sharp, light, and unmistakably amused as he raised the kunai she had left behind, twirling it between two fingers like a toy. "At least take these back!"

"Hmph. Keep them!" she shouted back without turning, her pace never slowing, though she felt her heart jolt—just once, just enough—because what startled her wasn't the words but the angle they'd come from; he wasn't behind her on the street anymore.

He was above her.

That realization sparked instant reflex as her eyes snapped upward, and sure enough, seated with almost bored nonchalance on the edge of the rooftop was Su Li, spinning her kunai idly between his fingers with a smile that didn't belong on a face so young, a smile that made something cold tighten in her spine. Her eyes widened instinctively as her mind struggled to trace the moment he'd moved—but there had been no moment.

Without hesitation, she launched away again, forcing her breath to steady as she landed on another rooftop deeper into the city, the world around her now a blur of tiled roofs and neon glow, her instincts screaming not fear but alarm as she glanced over her shoulder, fully expecting the impossible—yet still hoping not to see it.

But there was nothing.

"Miss Yoruichi, you really should take them. I'm not one for keeping debts," came the voice again, closer this time, too close, so close that her head whipped to the side before logic could catch up to instinct.

And there he was.

Already there. Already seated. Already smiling.

Not arriving. Not chasing. Waiting.

As if he had been one step ahead the entire time.

Her blood ran cold as understanding hit her like a slap—he wasn't keeping up with her movements; he was outpacing them. He had arrived before she had even chosen the next destination.

She clenched her fists tight, eyes narrowing with a surge of reluctant respect wrapped in competitive fury, and muttered through gritted teeth, "Hmph. So you really are fast. No wonder you beat Sui-Feng."

Then, with a heat that flared beneath her words, she growled low, "But if you think you can keep up with me—then try."

Her knees bent, one palm skimming the rooftop tiles for balance, every muscle in her body coiling like a spring before her voice, filled with smoldering pride, cut through the night, "Let me show you what real speed is. I'm the Flash Goddess for a reason."

A heartbeat later, she vanished in a thundercrack of compressed air, her afterimage barely forming before it dispersed like vapor in her wake.

Su Li's smile didn't flicker.

"Flash Goddess, huh…" he murmured to himself, more thoughtful than impressed.

And then he disappeared too.

Yoruichi hurtled through the night like a meteor, chaining together Shunpo after Shunpo so quickly the world beneath her became a smear of rooftops, wind, and moonlight, her movements honed to the edge of instinct, each step a defiance of space itself. Within seconds she had cleared miles, confident that she had finally shaken him, a smug smirk curling at her lips as the wind roared past—until the voice returned, soft and maddeningly close.

"Miss Yoruichi, I'm not really a fan of chasing women. I prefer being chased. So… here."

It came from beside her.

Not behind. Not below.

Beside.

She turned mid-air with the stiffness of disbelief, her wide eyes confirming what her mind refused to accept—Su Li was still there, gliding effortlessly in midair with the kunai in his hand and an expression that suggested mild amusement, not effort.

He wasn't winded.

He wasn't even trying.

Her lungs faltered, her breathing skipping a beat, because he wasn't just matching her—he was doing so with the same ease most people walked to market.

With a casual gesture, he raised the kunai and offered it to her, his voice light with teasing mockery, "Should I just put these in your pocket?"

Fury surged. She slapped his hand away in a flash of motion and vanished once more, this time unleashing everything—no restraints, no clever probing.

Instant Coax—full release.

All her spiritual energy flooded into speed, raw and blinding, the kind that fractured air itself, her body vanishing and reappearing faster than human senses could follow, her velocity now reaching a point that only the Captain Commander, or perhaps someone from the Zero Squad, could dream of matching—if even they could.

And yet… he followed.

Beneath the wide arc of the full moon, two shadows sliced across the sky like twin blades, racing above the slumbering city in silence so perfect it bordered on surreal. It might have been beautiful, elegant, something worthy of poetry or legend—but to Yoruichi, it was terrifying in a way she had never quite known.

She glanced back again, hoping this time to see distance.

But there he was.

Still there.

And worse—he was snacking.

A bag of chips in one hand, a bottle of soda in the other, Su Li drifted along beside her, biting into the chips with a satisfying crunch before sipping casually, then letting out a long, deeply pleased sigh. "Ahhh… this hits the spot."

All while keeping up.

Yoruichi's jaw clenched until it trembled, her pride cracking like glass under pressure, because the boy who had no business being here was not only matching her legendary speed but doing so with a picnic in hand.

She—Shihouin Yoruichi, the Flash Goddess of Soul Society—was being chased by a boy too lazy to even use both hands.

And for the first time in years, she felt the weight of her title waver, her identity shaken as the truth settled like a storm cloud over her head.

Who was this kid?

And more pressingly, who was the real Flash Goddess now?
