One morning, Gash Bell wakes up to find he has become a girl. He runs around screaming. But it's not just him. Kiyomaro is also a girl, Tio and Umagon have become boys, and Folgore has transformed into a woman of breathtaking beauty.
Due to the battle to decide the king of the demon world, an ancient curse has been triggered. To break the curse, they must find the 'Heart of Truth' within one week. But what is the 'Heart of Truth'? Nobody knows.
Panic erupts. Yet Gash, who can't ignore people i
Zatch Bell!! ~The Cursed Great Reversal!?~ - Great Panic! When I Woke Up, Everyone Was a Girl?!
"Uwaaaaaah!"
Morning. A scream echoed from the second floor of the Takamine house in the Hanazono-dai district of Mochinoki City. The morning sun streaming through the window should have been making fluffy blond hair sparkle brilliantly.
"Wh-wh-what is this?!"
In front of the bathroom mirror. Gash Bell blinked rapidly. Round brown eyes stared back at their own reflection. But something was off. Their voice was a little higher. And their hair had grown down to their shoulders. Their precious blue outfit had also, before they knew it, become shorter in length, looking almost like a skirt.
"Kiyomaro! Kiyomaro, where are you?!"
They clattered down the stairs. Their small body felt less balanced than usual, and their legs tangled just three steps from the bottom.
"Whoa!"
Thud-thud-crash!
"Oww... why am I tripping so much today..."
Rubbing the small horn-like protrusion on their head, Gash burst into the living room.
"Kiyomaro! It's terrible! I... my body is weird!"
Standing there was an unfamiliar beautiful girl.
Long, glossy black hair flowed smoothly down to her waist. Intelligent, narrow brown eyes—but now they were wide open, frozen as she gripped a hand mirror. Her uniform... the Mochinoki First Middle School uniform had clearly transformed into a girl's design.
"............"
The two stared at each other.
"A-are you... Kiyomaro...?"
"...As you can see."
A low, calm voice. But their hand was trembling slightly.
"How did this happen?! Kiyomaro, you've turned into a girl!"
"Shut up! I don't know either!"
That's when it happened.
The sound of the front door clicking open.
"Gash, are you there?"
A husky, somewhat ikemen voice. When Gash and Kiyomaro looked toward the entrance simultaneously, an unbelievable sight unfolded before them.
A boy with short-cropped vivid purple hair and strong-willed amethyst eyes stood there. He was just a little taller than Gash. But his arms were strangely muscular, visible even through his clothes.
"Huh... Tio, is that you?!"
"Yes!... I mean, yes! Why am I so buff like this?!"
Tio stomped inside. Standing in front of the mirror, they pinched their own upper arm.
"Noooo! My delicate body!"
"You were using masculine speech just now, but suddenly switched back to feminine speech."
"Shut up! I'm confused here!"
The commotion continued.
"Buono giorno! Everyone, are you doing well?!"
From outside the window came an oddly alluring woman's voice. Yet the tone was completely Folgore.
Everyone looked outside.
Wavy platinum blonde hair reaching down to the waist. Deep, clear sapphire blue eyes that could captivate anyone. A peerless beauty was striking a pose in the Takamine family garden.
"How beautiful I am! Mirror, mirror, who is the fairest of them all? Why, it's me, of course!"
"Folgore! What are you doing, even you?!"
"Oh my, that tone... could it be you, Tio? Hmm, you've become quite handsome. Though you can't match my beauty!"
"Who's competing with you?! More importantly, why are you so calm?!"
"Calm? How could I not be? Having become this beautiful, I can only see it as destiny!"
Folgore dreamily swept up their own hair. Just that gesture was somehow incredibly sensual.
"Merumeru..."
Before anyone noticed, Umagon was yawning in the corner of the room. Their entire body was covered in fluffy silver-white fur. Their large, gentle, intelligent dark eyes were the same as always. Except there was a ribbon on top of their head.
"Umagon! You've got a ribbon on!"
"Meru."
Umagon tilted their head, seemingly unconcerned. Even looking like a mare, they were too laid-back.
"Umagon isn't panicking at all..."
"...Quiet down for a moment."
At Kiyomaro's single remark, everyone stopped dead.
"Let's sort out the situation. First, all of our genders have changed. This isn't a coincidence."
"Wh-what do you mean, Kiyomaro?"
"Wait here. I'll look into it."
Kiyomaro ran up to their room on the second floor. The room was piled with ancient demon world texts they had collected as reference material for the battle to become king. The once-in-a-millennium battle where demon children and human partners fought together. In preparation for it, Kiyomaro had been reading through every document imaginable to be able to handle anything that might happen.
"...Found it."
A bundle of old parchment. Titled "Dimna Zora Artifact Catalog," it listed dangerous curse devices built by an ancient sage collective of the demon world.
"Volca Medira... sealed 200 meters underground in the Grave Basin of the southern demon world. Automatically activates when the magical energy waves of battle exceed critical levels... initiates a gender-swap curse..."
Kiyomaro's fingers trembled.
"The curse progresses in stages over seven days. Days 1-2: only physical changes. From days 3-4: begins affecting emotions and thoughts. From day 5 onward... memory alteration begins. If it exceeds the seventh day—you completely forget your original self."
A gulping sound. Before anyone knew it, Gash and the others were standing at the room's entrance.
"Forget... our original selves...?"
"That's right. If this continues, all of us will become different people in these bodies."
"What! That's wonderful! Then I shall remain in this beauty forever! Bravo!"
"Ask about how to break the curse! You narcissist!"
Kiyomaro opened the last page.
"The condition for breaking it is... 'The Heart of Truth.' It says only those who do not deceive themselves can shatter the mirror."
"Heart of Truth? What's that? Is it food?"
"I don't know. But if we don't find it, we're all finished in a week."
"Then! It must be words of love! I shall whisper love to gentlemen all over the world—"
"All you ever talk about is your own beauty!"
The two started grappling. The sight of a handsome guy and a beautiful woman tussling was becoming something else entirely.
"Merumeru..."
Umagon yawned again.
Gash watched everyone making a racket intently.
(Kiyomaro is making a scary face...)
Kiyomaro, who could usually do anything, had been reading the ancient text with a trembling voice. That pricked at Gash's chest.
"...I'm definitely going back to normal!"
At the sudden loud voice, everyone stopped moving.
"Because Kiyomaro is in trouble. Tio hates this too. How can I ignore it when my friends are in trouble?! I'll definitely break this curse!"
Clenching their small fist tightly, Gash smiled. It was a straightforward smile, like the sun.
Seeing that, Kiyomaro felt a tight warmth deep in their chest.
(What... is this...)
Gash, who had become a girl. Blond hair touching their shoulders. A slightly higher voice. But that sense of justice hadn't changed at all.
(...Cute.)
No, that's not it. That's not right. This is because of the curse. Kiyomaro shook their head.
"...Alright. Tomorrow, let's go to the Mochinoki City Library. It's a fifteen-minute walk from Hanazono-dai. There might be more detailed materials there."
"Yeah! Leave it to me, Kiyomaro!"
"Hmph, the library, huh. Well, fine. I'll go too. Now that I've got a man's body, I've gotta protect Gash."
"I shall use my beauty to gather information around town! After all, I'm so beautiful everyone will turn their heads!"
"...No one's expecting anything from you."
Evening.
Kiyomaro stood alone by the window of their room. Outside the window, the residential area of Hanazono-dai spread out. The sunset dyed the town orange, and crows cawed in the distance.
"...Gash."
They murmured quietly.
They remembered that smile from earlier. Their chest ached with a prickling sensation.
"What is this feeling..."
It's because of the curse. It has to be. But that ancient text said emotional changes wouldn't start until the third day. It was still only the first day.
(Then, this pounding heart is...)
Kiyomaro scratched their head furiously.
"Dammit, this makes no sense!"
Just then, there was a noise behind them.
"Kiyomaro? What's wrong? Does your stomach hurt?"
Turning around, Gash was standing there before they knew it. Their blue outfit, now like a skirt, sparkled in the sunset.
"...No, it's nothing. More importantly, tomorrow's an early morning. Go to bed early."
"Yeah! Goodnight, Kiyomaro!"
A small back pattered away.
Kiyomaro looked outside the window again.
"...A week, huh."
If the curse isn't broken, everyone will become different people. That was scary too.
But, more than that.
"If this feeling isn't because of the curse... then I..."
They couldn't finish the sentence.
Just that something deep in their chest had definitely begun to stir.
