Kato Megumi was completely stunned by Izumi's sudden declaration.
Mahou shoujo? What kind of nonsense was that?
Her gaze shifted toward the outfit in Izumi's hands.
After staring for a few seconds, her expression turned very, very odd.
"…You mean that?"
"You're sure it's not just… cosplay?"
Izumi nodded with confidence.
"Nope. This is the transformation device I made."
"It can turn someone into a real magical girl. They can actually use magic."
"Though the one I'm holding isn't suitable for you. If you want one, I can make a set for you later."
While he said that, Izumi gave Megumi a mischievous grin.
Megumi didn't believe a word of it. Looking at the outfit, it still looked like cosplay no matter the angle.
But Izumi didn't bother explaining. There was no need to rush.
After all, this one wasn't made for Megumi.
Once she saw Le Fay use it, she would understand perfectly well how terrifying this thing was.
With that thought, Izumi turned toward Ophis.
"Ophis, can you give me a bit of your power crystallization?"
"I still need your energy as the core."
Ophis lifted her head and looked at him, then at the clothing in his hand, and—without refusal—gathered her power.
A small crystal formed in her palm, and she casually tossed it to Izumi.
Izumi caught it and examined it closely—and was immediately shocked.
This tiny stone alone contained Demon King–level magic.
As expected of Ophis.
He prepared to begin the final stage of crafting, embedding the crystal into the materials…
but then paused.
If Ophis' power worked, then—
Wouldn't his blood also work?
His blood contained stellar particles. In theory, it could serve as part of the core as well.
Thinking this, Izumi looked at the crystal in his hand and decisively forced out a few drops of his own blood, merging them into the crystal.
The moment he did so—
Avrora's head snapped in his direction.
Drool nearly leaked from her lips.
Her expression screamed: I want that. I want to drink that SO MUCH.
Izumi ignored her and focused on merging his blood with Ophis' power.
The crystal instantly grew stronger—
even gaining properties from Izumi's Third Perpetual Motion Engine.
It could generate magic endlessly, albeit slowly.
Combined with Ophis' infinite energy, the crystal would constantly accumulate and store magic whenever it wasn't being used.
Izumi's eyes lit up.
"Good stuff! My blood can do this too?"
This was the first time he'd discovered such an ability, and it was honestly insane.
Without hesitation, he embedded the crystal into the materials.
Alchemy activated, and the materials, outfit fragments, and crystal all merged, forming a swirling mass of multicolored liquid.
Seeing the liquid, Izumi wasted no time and shaped it into the form of Dark Magician Girl's staff.
When he finished, the transformation device was complete.
The wand looked like a cute toy, but Izumi couldn't stop grinning.
Megumi was stunned.
So this really was a magical-girl transformation device?
Meaning everything Izumi had said… was true?
Her heart started beating faster.
If that was the case—she could actually become a mage someday.
After playing with the device for a moment, Izumi handed it to Le Fay.
"Le Fay, it's time."
"Transform for me."
Le Fay's eyes sparkled like gemstones.
"Yes, Izumi-sama!!"
"I'll try it right now!"
She excitedly took the wand.
Izumi walked her through the activation chant.
"Alright, repeat after me—"
"Henshin!!!"
Le Fay took a deep breath.
"Henshin!!"
The moment her voice rang out, the wand burst into radiant light.
A magic circle appeared above her head—
another beneath her feet.
The moment both circles activated, beams swept across her entire body.
A flash of white light—
And Le Fay's outfit changed entirely.
She had transformed into a perfect replica of Dark Magician Girl.
Golden hair, the iconic outfit, the unusual staff—an absolute 1:1 copy.
Izumi's excitement spiked.
He'd really done it.
A magical girl—he had actually created one!
Beautiful. Gorgeous. Amazing!
Le Fay's power surged instantly to Demon King level.
The magic flowing from her was overwhelming.
This transformation device was only Izumi's first prototype, designed purely for massive magic output.
With Ophis' crystal and Izumi's stellar-powered blood merged inside—
Le Fay now possessed nearly infinite magical energy.
A walking artillery turret.
If he could acquire time-attribute or space-attribute cores in the future…
He could even make transformation devices infused with those properties.
Le Fay felt the magic pouring through her and grinned with satisfaction.
"Hehehe, Izumi-sama! I'm super strong now!"
"I'm not even scared of fighting Avrora!"
Izumi instantly rolled his eyes.
"Don't bother. Avrora is useless in combat."
"She only knows how to eat. She's better off as a mascot."
He had never expected Avrora to fight.
With her adorable dumb-cute personality, she'd probably cry if someone hit her.
She wasn't the original ancestor.
This Avrora had zero combat instinct.
Being looked down on so thoroughly, Avrora puffed her cheeks angrily.
She was the Fourth Primogenitor!
How dare he disrespect her!?
She wanted to punch him!
Izumi ignored her and continued examining the device with Le Fay, asking whether anything felt off or needed improvement.
Since this was his first attempt, he was worried about defects.
But after Le Fay carefully sensed her own magic flow, she found nothing that needed fixing.
This device was simply too perfect for her.
Her weakness had always been insufficient magic.
Now, with the device, she could turn her vast magical knowledge into real, destructive power.
For her, it was flawless.
Hearing this, Izumi nodded proudly.
Looks like he really was that good.
With no apparent issues, the only thing left was to test it in actual combat.
