The morning sky was a clear blue, dotted with soft white clouds drifting lazily above. The sun shone brightly, bathing the world in a gentle golden warmth. Through the window of a modern bedroom, sunlight spilled inside as the curtains swayed softly in the breeze.
Yuuki Kaito, an eighteen-year-old high school boy, lay sprawled across a white bed, his body fully wrapped in the sheets.
Slowly, Yuuki opened his eyes.
The world felt blurred, distant—off somehow.
"Strange… I don't feel hardened today. Is something wrong…?" he thought, rubbing his eyes.
But the moment he moved, something didn't feel right. Felt too soft.
His fingers brushed against his hair, and his body stiffened.
"…Why does my hair feel this long?"
The strands spilled over his shoulders and chest. Confused, Yuuki shifted beneath the blanket and carefully pulled it down.
His chest felt unnaturally heavy.
Yuuki's eyes widened in horror.
With shaking hands, he slowly lowered one hand toward his waist, panic rising as he tried to confirm why nothing felt right anymore.
[Touching… touching—right on the spot]
"Aaahh~"
A soft moan escaped his lips. Yuuki froze as he blinked.
His cheeks burned crimson as his body trembled, shock ripping through him.
"W–Wait… what was that sound?"
"…Did that really come from me?"
Heart racing, Yuuki threw the sheets completely off his body. What he saw drained the color from his face.
His flat chest was gone—replaced by a pair of unmistakably feminine curves, feels heavy. His sleeping pajamas, made for a male body, clung tightly to places they never should have.
"…What the hell?!"
His voice cracked.
"Where is my—no way… ain't no way I got a hole?!"
His breath hitched.
"Am I… becoming a girl?!"
Yuuki screamed as he jumped off the bed and rushed toward the mirror attached to his almirah.
The reflection staring back at him made his legs nearly give out.
Standing there wasn't the boy he had known his whole life—but a girl.
Long, flowing black hair draped past his shoulders. His eyes looked softer, darker. His height was shorter than before, while his breasts and thighs strained against the too-tight pajamas.
Yuuki stared.
And stared.
His jaw dropped.
"Th–This is… me?"
"But… how?"
He slowly staggered backward, his mind spinning. Last night. His family in the living room, his father, smiling proudly as he demonstrated some ridiculous magic like it was harmless fun.
Yuuki clenched his fists, teeth grinding. Eyes narrowed.
"Tch… now I get it."
His soft eyes trembled with fury.
Without a second thought, Yuuki yanked open his door and stormed toward his father's room.
BAM!!
The door burst open violently.
Yuuki's father—short-haired, glasses slightly crooked, around forty-five and annoyingly handsome—sat calmly at his desk, wearing a blue-and-white shirt with black pants, reading a book.
The room shook. His glasses slipped down his nose.
"PAPAAAAA!!!"
Yuuki roared from the doorway.
"Eh?" His father blinked. "What happened, honey…? Your voice sounds strange-"
He turned around. His eyes widened as he stared at Yuuki's feminine body.
"…Wait. This isn't my wife. Who is she…?" he thought, sweat forming instantly.
Before he could react, Yuuki stomped forward, his chest bouncing under the pajamas with every step. Hands planted firmly on his hips, he glared up at his father with pure rage.
"I LOST IT AND GOT A HOLE!! Because of your stupid magic!!"
He pointed at himself furiously.
"I am your son, remember?!"
His father's eyes widened as he scanned Yuuki from head to toe.
"Huh?! Got a hole from my magic, son?" he said, standing up.
"What do you even mean, 'hole'? Hole… where?"
"HUH?!" Yuuki snapped.
"Hurry up and bring me back already!!"
"Son, I really don't understand—"
Yuuki's face burned red as he grabbed his father by the collar and pulled him closer.
"Look at me carefully!!" he shouted.
His father squinted, studying him carefully.
"…Yeah, son. You do seem… different."
"OF COURSE I AM!"
Yuuki yelled.
" I became a girl now!!"
His father adjusted his glasses slowly, the lenses catching the light as he stepped back toward the balcony door.
They glinted ominously.
"Oh, I see," he said calmly.
"Congratulations on becoming my daughter."
Yuuki's jaw dropped.
"What the—"
Footsteps echoed as the door creaked open.
Yuuki's mother, Hanae Kaito, stepped into the room.
She was a woman in her mid-thirties, with fair skin, shiny brown eyes, and long brown hair tied neatly into a ponytail. She wore a simple light shirt dress paired with a long white skirt, a yellow apron wrapped around her waist, a spoon still resting in her hand.
"What's going on this early in the morning? Darling, which girl were you talking wi—"
She stopped.
Completely.
Her eyes landed on her husband.
Then shifted.
And froze on the beautiful girl standing there in oversized sleeping pajamas.
The shine in Hanae's eyes vanished in an instant. Her body stiffened like she had turned into stone, color draining from her face.
"D–Darling…" she muttered softly.
"What… is this…?"
The room fell silent.
Yuuki and his father, Ryuji Kaito, both turned toward her.
Without the slightest bit of hesitation—or guilt—Ryuji casually lifted his hand and pointed straight at Yuuki.
"Yo, honey. Look," he said calmly.
"Our son's a daughter now. Looks like yesterday's magic worked a little too well."
Yuuki shot him an absolutely murderous glare.
Before Yuuki could even open his mouth to explain—
"KYAAAAA!!!"
Hanae suddenly screamed.
The color rushed back into her face as her eyes sparkled like shining stars. She clasped her hands together, staring at Yuuki in disbelief.
"A daughter?!"
"Darling, are you really telling the truth?!"
Her expression lit up.
"I'm so happy! I always wanted a daughter!"
"WAIT—"
But it was too late as Hanae dashed forward and wrapped Yuuki in a tight embrace, rubbing her cheeks affectionately against him.
"Aagh—mom, stop it!!" Yuuki shouted, struggling.
"This is NOT happy news!!"
Hanae only held him tighter.
Behind Yuuki, Ryuji placed a proud hand on his shoulder. His glasses gleamed as he raised his thumb confidently.
"Yuuki… this truly is wonderful news for our family."
Yuuki snapped his head back.
"STOP BEING SO PROUD ABOUT IT!!"
"This is literally all your fault!!!"
Yuuki's screams echoed through the entire house.
[And just like that, an ordinary morning turned into a blessing—for this family, in stupid way.]
By 8:00 AM, the dining table was neatly set.
Hanae hummed cheerfully as she placed plates of bread and eggs onto the table.
Yuuki sat stiffly in his chair, his face burning red.
He was dressed in his mother's purple skater dress paired with a half-white skirt—an outfit forced upon him without resistance being accepted. Meanwhile, his father Ryuji sat comfortably across from him, legs crossed as he read the morning newspaper like nothing had happened.
"Why are they acting so normal…?" Yuuki thought bitterly.
"This feels insanely stupid…"
Just then—
"Yawwwn…"
Yuuki's younger brother, Einosuke Kaito, shuffled into the dining room.
Sixteen years old, a high school student with messy deep-brown hair and shiny brown eyes, he wore cyan-colored sleeping pajamas as he lazily rubbed his eyes.
Then—
Einosuke's eyes gazed at Yuuki.
A sparkling, beautiful girl sitting quietly at the dining table. The long shiny hair, the adorable face.
Einosuke's eyes widened fully.
"Huh…?"
"Who is that girl…? A guest? She's so beautiful and cute!"
He stared at the Yuuki, he froze.
Yuuki noticed Einosuke but deliberately pretended like he didn't saw Einosuke.
Curiously Einosuke stepped closer to Hanae.
"Mom," he asked softly, "who's that cute girl? Is she our relative?"
Hanae giggled and glanced at Yuuki.
"Of course not," she said warmly.
"She's your cute big sister, sweetie."
"…Huh?"
Einosuke froze.
"Big… sister? What do you even mean, mom?!"
His eyes slowly shifted back to Yuuki.
Yuuki clenched his fists.
"Damn it…"
"This is way too much for me."
"Yuuki," Hanae said gently, "tell your little brother about yourself. Talk with your big sister while mom prepares your bag."
Yuuki slammed both hands on the table and stood up, his eyes blazing red.
"Mom!" he shouted.
"STOP calling me 'sister,' okay?! I'm still me! My body just changed—that's all!"
Ryuji lowered his newspaper slightly, his expression caught between guilt and amusement.
Einosuke blinked rapidly to Yuuki
"W–Wait… that means you're my big brother, Yuuki?!"
"Of course I am!!"
Yuuki plopped back into his chair and puffed his cheeks in irritation.
Einosuke slowly sat down beside him. Einosuke was silent.
[STARE~ STARE~]
"…Why the hell is this idiot staring at me like that?" Yuuki thought, turning his head.
"Ahem," Yuuki snapped.
"Do you want to ask something? Stop staring like this, okay?"
Einosuke finally looked away, scratching his head awkwardly.
"S–So, sister. How did you become a girl like this?"
As Einosuke finished his words, Yuuki grabbed Einosuke by the collar and yanked him close, teeth clenched in rage.
"DON'T call me sister, idiot," Yuuki growled.
"Say it one more time, and I won't forgive you."
His soft black eyes burned red.
Einosuke started coughing, sweat pouring down his face as fear overtook him.
"S–SORRRYYY, BIG BROOO!!!"
Yuuki released him with a shove.
[And thus, the new life of Yuuki Kaito had officially begun as a girl.]
