Haikyuu!! Cursed Gender Swap!? Ushiwaka Became a Girl!?
Hinata Shouyou wakes up expecting an ordinary morning of training camp—not to find a stranger staring back from the mirror. A girl with wild orange hair and his same stubborn eyes. One scream later, he discovers he's not alone: Kageyama, Sugawara, and the rest of Karasuno have all fallen victim to the same bizarre curse. And it doesn't stop there—phone calls flood in from Aoba Johsai, Shiratorizawa, Nekoma, Fukurodani, and beyond. Volleyball's fiercest rivals, from the cool-headed to the downrig
Haikyuu!! Cursed Gender Swap!? Ushiwaka Became a Girl!? - Ushiwaka accepts the curse.
When they arrived at the entrance to the mountain path, Hinata Shouyou couldn't believe his eyes.
In front of the weathered torii gate, familiar faces were lined up in a row. And every single one of them was a girl.
"Kenma! Bokuto-san! Wait, even the Miya twins!?"
When Hinata shouted, Kozume Kenma of Nekoma lazily lifted his head.
His long black hair swayed softly in the mountain breeze. The ends, which bounced up like bedhead, rested against the nape of his neck. His skin, already pale to begin with, looked even more translucent now that he'd been turned into a girl. Only his cat-like eyes remained as sleepy-looking as ever.
"……You're loud. Your voice is too big."
Beside Kozume, Bokuto Koutarou of Fukuroudani grinned, showing his white teeth.
His nearly-golden brown hair was tied up high in a single ponytail. Every time the ponytail bounced, it scattered the sunlight. He was still as tall as ever, and even in a girl's jersey, those shoulders were unmistakably those of an ace.
"Ohh! Hinata! You're still tiny even as a girl!"
"Bokuto-san, your voice is still huge even as a girl too!"
"Hahaha! Obviously! I'm still me!"
Bokuto grabbed Hinata's head with a firm grip. He'd always been aggressive about treating him like a kouhai. Even with a girl's hands now, the force was exactly the same as always.
From behind Hinata, Kageyama Tobio stepped forward, looking displeased.
"Bokuto-san. Let go of him."
"Huh? Why should I? Hinata's my kouhai."
"Even if he's your kouhai, right now, he's my partner."
"Hah!? Don't go deciding that on your own!"
"I didn't decide it on my own. He declared it himself in the clubroom yesterday."
"What the hell, I never heard about that!"
Caught between the two of them, Hinata waved his hands frantically.
"H-hey! It's still too early for this! Calm down!"
Beside them, Miya Atsumu and Miya Osamu of Inarizaki were fighting over a single hand mirror.
The feminized twins' appearances were terrifyingly complete. Both of them had model-like facial structures and sharp, narrow eyes. Atsumu's hair was a lighter brown, while Osamu's was a calmer dark brown. There was almost no height difference between them. Standing side by side, they looked like a pair of perfectly symmetrical dolls.
"Osamu, lend it to me for a second. I need to check my face."
"Idiot. I'm looking at your face for you, so it's fine. Mine's better-looking anyway."
"Hah? Where the hell are you looking? Say that again after looking in the mirror."
"I looked. That's why I'm saying it."
"Why you—"
Atsumu grabbed Osamu by the chest—no, by the collar of her girl's jersey.
"Now, now, you two. Stop it."
Oikawa swept in, her glossy curled hair swaying. The sight of her in Aoba Jousai's girls' uniform didn't feel out of place on a mountain path at all, which was terrifying. This person could make any place her own.
"You twins are still so close even as girls. Fighting over a mirror like that—it's adorable, just like high school girls."
"Who's a high school girl? I'm a guy."
"Saying that while looking like that has zero persuasive power."
"You're one to talk!"
"I had the talent to be a beauty from the start. I'm on a completely different level from you two."
Oikawa spun around once. The hem of her skirt spread out like a flower.
"Whoa……"
"Hey, Hinata-kun. You were just staring, weren't you. I can hear your inner thoughts, you know."
"Whoa! You heard that!?"
Hinata clapped his hand over his mouth. This was bad. This curse's range might be expanding.
Kozume let out a small sigh.
"……Hah. It's too noisy. I'm getting a headache."
"Are you okay? Kenma, you don't look so good."
Sugawara softly stepped up beside Kozume. Her silver hair caught the sunlight filtering through the trees, glowing white.
"Sugawara-san. It's been a while."
"It has. So you've become a girl too, Kenma. But somehow, your whole vibe is exactly the same."
"……Is that a compliment?"
"Yes. You're calm, and it's very you."
Kozume's mouth relaxed just a little. For some reason, talking to this person put him at ease.
At that moment, Bokuto suddenly raised his voice.
"Alright! Everyone's here! Let's go! Mountain climbing, start!"
"Wait. Not everyone's here yet."
"Huh? Who's missing?"
"Shiratorizawa isn't here yet."
The moment that name came up, the air grew slightly heavier.
Nekoma, Fukuroudani, Inarizaki, Karasuno, Aoba Jousai. This many national-level powerhouses had gathered. The only one missing was that man—the strongest in Miyagi.
"Ushijima Wakatoshi……"
Kozume murmured quietly.
"Is he really coming? I heard through the contact chain that he got turned into a girl by the curse."
"Of course he'll come. There's no way that man would turn down an invitation. He might not care about investigating the curse, but if all his rivals are gathering, he'll definitely show his face."
Oikawa's voice was laughing, but there was an edge to it somewhere.
"Oikawa-san, you really understand Ushiwaka, huh."
"It's not that I want to understand him. The way that rock of a man thinks is mostly simple."
At that moment, from the mountain path behind them, footsteps echoed—tap, tap.
A steady rhythm. An unwavering, straight way of walking.
He knew before he even turned around.
Ushijima Wakatoshi was standing there.
Even as a girl, that pressure hadn't changed at all.
Her jet-black short hair was perfectly neat, even without any wind. Her deep, dark-brown eyes stared straight at them. Her height was still outstandingly tall. The white and purple Shiratorizawa jersey stood out against the green of the mountain path with an almost eerie vividness.
"……Ushijima."
Kageyama called the name in a low voice.
Ushijima silently surveyed the group. Slowly, as if appraising each person one by one.
Then, she raised both hands, opening and closing them.
"……Light. There's less fat."
Ushijima's voice was a low female voice. Even so, the intimidation factor had, if anything, increased.
"This body has less fat that's unnecessary for volleyball. It moves faster, and there's no weight to hinder my jumps. ——This is evolution."
For a moment, the entire mountain fell silent.
Even the birdsong seemed to vanish.
"……Huh? What are you talking about?"
Miya Atsumu's mouth hung open.
"Exactly what I said. This body is suited for volleyball. There's no need to break the curse. I will test how high I can jump with this body."
"Hey, are you serious!?"
Hinata's voice cracked.
"I am serious."
"If we don't break the curse, then everyone else can't go back to normal either, you know!?"
"If you all want to go back, then go back. I'll do as I please."
At that moment, a cackling laugh echoed through the mountains.
Oikawa was doubled over, laughing hysterically.
"Ahahahaha! Ushiwaka, you really are an idiot, aren't you!"
Oikawa kept laughing, tears welling up in her eyes.
"Evolution!? A girl's body!? Have you actually looked in a mirror and seen what you look like right now!?"
"I looked. There's no particular problem."
"No problem, she says! Just try imagining yourself spiking with that chest! Everyone's eyes will be glued to your boobs!"
"People's gazes have nothing to do with play."
"They absolutely do! What are you even looking at in volleyball!? Every time you jump, am I supposed to be the one radiating sex appeal!?"
"……Oikawa, you already radiate more than enough sex appeal."
Oikawa's laughter stopped dead.
"Hah? Was that a dig at me just now?"
"It wasn't a dig. It's a fact."
"Ushiwaka, you—!"
Oikawa stepped forward. Iwaizumi Hajime grabbed her shoulder from behind, hard.
"Oikawa, calm down. Don't step into his arena."
Iwaizumi was Aoba Jousai's ace and Oikawa's childhood friend. Even as a girl, that solid build, the close-cropped hair, and the sharp eyes hadn't changed at all. If anything, just standing there silently made her look dependable.
"Iwa-chan! But he—!"
"I know. That's why I'll talk."
Iwaizumi stepped forward, in front of Ushijima.
"Ushijima. Your way of thinking is your own business. But right now, if we don't all cooperate, we might not be able to break this curse. Even so, you're going to go it alone?"
"That's right. I walk my own path. You all should do the same."
"This is getting us nowhere……"
Iwaizumi's temple twitched.
At that moment, Hinata pressed his feet firmly into the dirt beneath him.
(This guy is serious. He's seriously trying to accept this curse and play volleyball.)
It was frustrating.
I want to go back to my original body. I want to take the number one spot again with Kageyama on that winter court.
But this guy says with a straight face that he can still fight in this body.
That strength—it was frustrating.
"……You're still a king, even like this."
Hinata's voice was trembling.
Ushijima's eyes turned toward Hinata.
"……What?"
"You can fight alone and win alone, so that's fine for you! But I'm different! I can't win without Kageyama's tosses!"
Hinata's voice bounced off the mountain slope again and again.
Kageyama stared intently at Hinata.
That's when it happened.
——Ushijima's inner voice could be heard.
(Oikawa's laughing face is beautiful.)
It was a quiet, clear voice.
The atmosphere froze in an instant.
Oikawa turned to stone.
"……Huh? What did you just say?"
"I didn't say anything."
"I heard it! Everyone heard it, right!? That inner voice just now! 'Oikawa's laughing face is beautiful'!"
"I heard it!"
"I heard it. Clearly."
"Ushiwaka, when you say 'laughing face,' do you mean my face when I'm laughing hysterically!? That's beautiful to you!? Are your eyes just holes in your head!?"
Oikawa turned bright red and launched into a tirade.
But at that moment, another voice leaked out.
This time, it was Oikawa's inner voice.
(Ushijima's chest…… you can tell even through that jersey. It looks really soft.)
Thud.
Iwaizumi's fist slammed into the back of Oikawa's head.
"You idiot! What the hell are you thinking right now!"
Oikawa collapsed to the ground.
"I-Iwa-chan…… that just now, it wasn't—it was involuntary—"
"Shut up! Have some shame!"
Iwaizumi was red up to her ears. The fact that her own inner voice was audible to herself was the greatest humiliation.
As if following that chaos, the inner voices around them began to chain-react.
First, Kageyama.
"Hit my tosses, Hinata."
It wasn't spoken aloud. It was his true feelings, overflowing from deep within.
(Hinata said he'd pair up with me. Then trust my tosses. Fly at my tosses with everything you've got. Don't give my tosses to anyone else.)
His possessiveness was completely exposed.
"……K-Kageyama!?"
Next, Sugawara.
(Ah, jeez. If Daichi were here in this situation, what would he say? I'd kind of like to know what Daichi's thinking.)
"……Eh!? Did I just say Daichi's name out loud!?"
Sugawara covered her mouth. Her white cheeks turned redder by the second.
"Sugawara-san, you were thinking about Sawamura-san, weren't you."
"N-no! That's not it! It's just, the situation—!"
And then, Kozume.
(If I paired up with Hinata, it might be fun. Hinata is, somehow, never boring.)
"……Ah."
Kozume realized his inner voice had been heard, and turned red all the way down his neck.
"Oh! Kenma, you're after Hinata too! But listen, Hinata's my kouhai! Hinata and me, we're the ultimate duo!!"
Bokuto's inner voice had zero intention of hiding anything from the start.
(Hinata's jumps are fun to watch. That small body flying to its absolute limit. I want to jump higher too. I want to compete with Hinata.)
It was a voice mixing expectations for a kouhai with the instincts of an ace.
"Hey, Hinata! Pair up with me! It'll definitely be fun!"
"E-eh!? Bokuto-san too!?"
Miya Atsumu grinned.
"Heh. That little shrimp is pretty popular, huh. Well, that little shrimp's jumping power—as a setter, I'd love to get my hands on it. I want to see what kind of toss can draw out that speed."
"Atsumu's greed is as deep as ever."
"Shut up. You're happy about becoming a girl too, aren't you."
"I'm not happy at
