Seraph Squad Gender-Bender Panic! ~The Day My Girlfriend Became My Boyfriend~
One morning, Cadet Karen wakes up to find the world has turned upside down.
She looks in the mirror and screams. The face staring back is sharper, with a faint stubble on the chin. In a panic, she checks under her shirt—her chest is flat. And there's something extra down below. "Wait, does this mean... I'm a guy?!"
Out in the hallway, the entire military dormitory is in chaos. The cool female instructor Yui has become a muscle-bound man, and the gentle senior Ryo is now a cute girl. Boys are g
Seraph Squad Gender-Bender Panic! ~The Day My Girlfriend Became My Boyfriend~ - I Woke Up as Me!? A Morning of Total Panic
"……Huh? Wha—?"
My voice is weird.
Rubbing my sleepy eyes, Karen sat up in bed. Monday morning. Outside the window, the sound of wind through the Evergreen Forest, and in the distance, the pounding footsteps of cadets on their morning run. Fort Mirage mornings are always like this.
But today, something's off.
First, my pajama sleeves are too short. And also, my chest area feels kind of… drafty?
"Huh? What the—"
I looked at my hands.
Big. Knobby. Not my usual hands.
"No way."
I jumped out of bed. The impact of landing felt way heavier than I expected.
I rushed into the bathroom and looked in the mirror.
"—GYAAAAAAAHHH!!"
I locked eyes with the man in the mirror.
Cropped short black hair. A sharp jawline. A faint shadow of stubble. Broad, solid shoulders, and a thick neck. The look in his eyes is a bit sharper, but if you look closely, those eyes are round and brown.
"Wait… is this… me?"
My voice is so deep. Every time I speak, my throat vibrates, and it feels seriously gross.
Hesitantly, I lifted the hem of my pajama top.
Gone.
My chest is gone.
"Hold on, hold on, hold on— then what about down below—"
Rustling around and peeking inside my pants, Karen nearly screamed again.
It's there. Something weird is attached.
"Wh-What is this?! I'm a girl, you know?! I'm eighteen, you know?!"
Panicking, Karen grabbed a uniform and bolted out of the room. The size is all wrong—the jacket sleeves end awkwardly just above the wrists. The cargo pants are too short too, leaving my ankles exposed.
The hallway was already in chaos.
"Uwaaah! My thing is gone!"
"Kyaaah! Who's this hottie?! Wait, that's me?!"
"Calm down, you guys! I mean, what the hell is this, me too!"
Screams and shouts flew back and forth everywhere. Everyone's body is completely different from yesterday.
Amidst the uproar, Karen spotted a figure standing at the end of the hallway and held her breath.
There stood a girl I didn't recognize.
Petite, delicate, with glossy black hair swaying down to her waist. Her large black eyes glistened, wet and shining, her features smooth, her skin looking so soft. The slender legs extending from her uniform skirt were somehow, really…
Thump.
Karen's heart made a strange sound.
"Huh… Ryou?"
My voice cracked.
My face is hot.
Yeah. That serious-looking face. The narrow but gentle eyes. The tiny star earring glinting on the left ear. It's definitely my best friend, Ryou.
But Ryou was supposed to be a guy. Way taller than me, with a deep voice.
And yet now, I'm the taller one. Looking down at the top of Ryou's head, it somehow makes me feel incredibly… protective.
"…Is that you, Karen?"
Ryou hesitantly spoke. That voice was high, like the chiming of a bell.
"Yeah… probably, I'm… I mean, I'm Karen."
"I see. It seems I've ended up in a body like this too."
Saying that, Ryou looked down at their own body.
And then, hung their head.
Ears bright red.
Thump, thump.
My heart is so loud.
Why? Ryou is my best friend. Being by my side was always just natural. I've never once felt this way before.
"Uh, hey, Ryou—"
"Wh-What?"
Our eyes meet.
Ryou's big eyes are wavering, full of unease.
Cute.
The moment I thought that, Karen felt her face get even hotter.
"…Never mind! A-Anyway, let's go check on everyone else!"
"R-Right. Yeah…"
Awkwardly averting their gazes, the two of them hurriedly started walking down the hallway.
Distance: fifty centimeters.
Normally we'd throw an arm around each other's shoulders or slap each other on the back, but right now, I just couldn't bring myself to touch Ryou. If I did, it felt like something bad would happen.
At the end of the hallway. In the dormitory entrance hall, more than ten cadets had already gathered.
As far as the eye could see, everyone was panicking over each other's transformed appearances.
"I was a girl until yesterday, you know?! Why am I all ripped like this?!"
"Does anyone know how to change back?!"
"Hey, you! Who were you originally? I can't tell at all!"
Total chaos.
This base is AVO—Allied Vanguard Organization, 7th Sector. A front-line base for fighting the enemy that comes through dimensional rifts called the Veil: the Seraphs. It's one of fourteen sectors worldwide, and nearly four hundred people are stationed here at Fort Mirage. Cadets like Karen are young people aged fourteen to twenty, chosen as future warrior candidates.
The training here is tough, but Karen loved this place. There were comrades, the instructors were strict but kind. The food in the mess hall is good, and going out to Tachibana City on weekends is fun.
But right now, that's the last thing on my mind.
"You lottttttt!!"
A low voice, like it was crawling along the ground, echoed through the hall.
Everyone's movements stopped dead.
Standing there was a giant of a man, easily 180 centimeters tall.
Rugged black hair cropped short. Sharp eyes full of strong will. Bulging muscles strained against a training tank top. Veins stood out on his thick arms, and his clenched fists were like boulders.
But the Instructor badge glinting on his left chest—that, I recognized.
"I-Instructor Yui…?"
"Shut it! That form of address is fine for now!"
Instructor Yui—full name Yui Sakamoto. Twenty-eight years old. Training supervisor for the 2nd Platoon, nicknamed "Demon Yui" for their strictness.
She was originally a stunningly beautiful instructor, proud of her glossy black hair tied back in a single ponytail. While feared by cadets like Karen, many girls admired her strength and beauty.
But.
Right now, Instructor Yui is, no matter how you look at it, a muscle-bound man.
"H-Hey, Instructor Yui… um, are you okay?"
"How could I possibly be okay?! I'm— this— this—!"
Instructor Yui started to say that, then suddenly caught sight of herself in a mirror hanging on the wall.
For a moment, her face twitched.
Then, her fists trembling violently,
"Aaaaaaaah! My face! My body! I took such good care of them until yesterdayyyyy!!"
That scream was almost a shriek.
The image of the demon instructor crumbled audibly.
"Um… Instructor, please calm down—"
"How can I calm down?! I've lived twenty-eight years as a woman, with a certain amount of pride—"
"Instructor! Everyone's watching!"
Ryou looked around as if suddenly realizing it.
The cadets were staring at the instructor, mouths agape.
Instructor Yui cleared her throat with a cough and forced her expression back to normal.
"…A-Anyway! We're assessing the current situation! Everyone, assemble in the Mess Hall! Anyone not there in five minutes gets double the usual training, and I'll give you plenty of personal attention!"
At that command, everyone finally started moving.
The cafeteria—officially the Mess Hall—was in an uproar.
A place that should normally be filled with the good smell of breakfast was now a crucible of anxiety and confusion. At the tables seating two hundred, familiar faces and unfamiliar faces sat in equal measure. More precisely, everyone is a familiar comrade, but only their faces and bodies are those of strangers.
"Alright, alright, everyone settle down, settle down!"
Amidst it all, an especially bright voice flew out from behind the counter.
The owner of the voice was a middle-aged man with thinning, naturally curly hair bouncing around.
But that apron-clad figure is familiar.
"Miki-san?!"
"Hm? Oh, Karen, is it! My, what an adorable boy you've turned into!"
Hasegawa Miki. Forty-five years old. The head chef in charge of this base's stomachs.
Normally a kind, motherly person with casually tied-up brown bun hair, now they're a cheerful-looking ossan with narrow, smiling eyes.
"My, my, I woke up, looked in the mirror, and this! What a rare experience!"
Miki-san slapped their own belly and laughed heartily.
Drawn by that voice, a few cadets started giggling.
"Miki-san, aren't you panicked?"
"No point in panicking, is there. When in doubt, eat! Today's a little fancier than usual—it's the salmon chanchan-yaki set meal!"
On the tray thrust forward, the savory aroma of butter indeed wafted up.
Unconsciously, Karen accepted the tray.
"Miki-san is the same as ever."
"Of course I am! My body might've changed, but my skills haven't! Now, eat up and calm down!"
Miki-san's sheer boldness lightened the atmosphere in the room a little.
As expected of the base's mother figure. As long as this person is here, things will surely work out.
Seeing that everyone had taken their seats, Instructor Yui spoke again.
In their hand was a fifteen-centimeter cube made of a material like obsidian.
"Listen up. This is the cause."
The mess hall fell dead silent.
"It was recovered from the North Gate警戒区域 by one of the platoons during last night's exercise. A cursed box left behind by a Seraph—an Anchor type."
A cursed box.
The Seraphs are invaders from another dimension that suddenly appeared fifteen years ago. Their forms vary wildly, and they're said to feed on human emotional energy. Among them, the large ones called Anchor types leave behind nasty traps like this after being defeated.
"Someone, in the middle of the night, carelessly opened this."
Instructor Yui's gaze slowly swept over the cadets with a glare.
Several of them flinched, their shoulders trembling.
Karen felt like she might or might not have some idea about it.
"Upon opening, a black, mist-like Flux was released from the box. Its effective radius was approximately two hundred meters. Nearly every human within the base received the curse of 'gender reversal' while they slept."
Flux. Supernatural energy that leaks from the Veil. Humans with aptitude take it into their bodies and use it to fight. Cadets like Karen and the Vanguards all undergo training to handle this Flux.
But the Flux that came out of the cursed box was apparently pitch black and extremely malicious.
"H-How do we change back?"
Someone asked in a trembling voice.
Instructor Yui showed everyone the inside of the cube they were holding. Dense ancient script, like squirming earthworms, was carved all over it.
"The key to breaking the curse lies in these characters. However, at this stage, we haven't deciphered them yet. Therefore—"
The instructor took a deep breath.
"We will investigate documents stored in the old research facility in the base's underground sector. The accompanying personnel will be Karen and Ryou from the 2nd Platoon. That is all."
"Eh?"
"Us?"
The two of them raised their voices simultaneously, and then simultaneously ended up meeting each other's eyes.
Thump.
There it is again. My chest tightens.
"Is there a problem? You two demonstrated good coordination even in exercises. Furthermore, Ryou's calm judgment and Karen's ability to take action are precisely what's needed in times like this."
When put that way, there's no arguing.
Karen glanced at Ryou's profile standing next to her. Ryou was looking down with a complicated expression.
That's when it happened.
Bump.
Ryou's slender, white fingers touched the back of Karen's hand, just barely.
"…It's okay. I'll protect you."
That small voice seeped warmly into the depths of Karen's ears.
Thump, thump, thump.
My chest is so loud, it feels like everyone's going to hear it.
Protect me, they said.
"I-It's not like I need you to protect me or anything! I'm fine on my own!"
"…Oh. I see."
Another awkward silence.
It's strange. Just until yesterday, this kind of atmosphere had never flowed between us.
Is it because of the curse?
Or was it actually there all along, and I just never noticed?
Karen looked at the back of her own hand. The spot where Ryou's fingers touched is still hot.
What is this feeling?
"Alright! We'll figure something out! We're definitely changing back!"
Karen deliberately raised her voice brightly, shaking off the atmosphere.
Ryou also smiled, looking a little troubled.
And so, a new day at Fort Mirage began amidst unprecedented chaos.
The true nature of the curse, and the new feelings awakening dee
