Aozaki Aoko Case File

The reason Aoko Aozaki can wield such outrageous Magic, which she has named Incineration Mode: Blue, lies in her use of the Fifth Magic to temporarily unify all versions of herself across different timelines.

This technique is distinct from Zelretch's Second Magic. Aoko's method is more akin to Goetia's. By burning a small portion of the universe's lifespan, she forcibly pulls otherwise unrelated parallel world timelines together, centering them on Aoko Alter.

As a result, Aoko doesn't need to worry about her alternate selves affecting her personality. After all, she's essentially treating her other versions as temporary ammunition—and bullets don't possess the shooter, right?

With one light cannon shot, she burned a hole clean through a mountain. At that moment, Aoko felt ecstatic, like she was on cloud nine. No wonder so many people in this world are obsessed with light cannons.

That said, Aoko believes the Fifth Magic shouldn't be used too frequently. Each large-scale usage seems to attract strange beings claiming to uphold justice, who then fight her to the death—a recurring nuisance that gives her no end of headaches.

In comparison, the power she currently derives from the Woven Fragment might be far weaker than that of a true magic user, but it's a safer, cumulative system with no side effects.

As long as her archmage level remains high enough, paired with regular magecraft, she feels confident she can handle most opponents.

When Aoko fought Touko, it might have seemed like an effortless victory, but in truth, Aoko was extremely cautious about managing the output of her Fifth Magic. She had no intention of killing her sister. Even the light cannon she unleashed at the end was aimed away from Touko—more for intimidation and to make her suffer just a little.

In the original timeline, Touko Aozaki had been completely twisted—trained by that old man to the point where she had no morals or familial bonds. Her occasional fits of madness had been terrifying.

However, in this timeline, thanks to Aoko's efforts, Touko is no longer the cold and ruthless Scarred Red. Though still far from normal, she had become much more adorable—and far more tolerable as a sister.

Even so, Aoko wasn't entirely satisfied with her correction results. So this time, she decided to employ some special methods.

...

Pushing open the door of a nearby building at the battle site, Aoko activated the Mirror Slumber and instantly returned to the Kuonji Mansion's living room.

She tossed the cocoon-shaped bundle she'd been carrying over her shoulder onto the sofa before collapsing next to it like a worn-out office worker.

"Did you win?"

Alice Kuonji, descending the stairs, immediately asked upon seeing Aoko's return.

"That's just Touko. It was a piece of cake!"

Aoko boasted, flashing a triumphant "V" sign.

"And this?"

Alice asked, gesturing toward the bundle on the sofa.

"That's Touko," Aoko replied nonchalantly. She pulled back one end of the cocoon, revealing a cute, unconscious face inside.

"...What happened to her?"

Alice asked curiously, leaning in to pinch Touko's tender cheek.

"I gave her some of my exclusive membership mysterious drink!"

Aoko announced proudly, grinning as if she'd just executed a brilliant plan.

Aoko's noisy declaration eventually woke the unconscious Touko. Letting out an adorable "Ngh," she groggily opened her eyes—only to find Aoko and Alice staring at her with amusement. Their schadenfreude-filled gazes jolted her into full alertness.

She tried to jump up but quickly realized she was tightly bound in cloth. The animated ropes restraining her wriggled like snakes.

"Aoko!"

Touko shouted in a high-pitched, childish voice.

"What is going on?!"

"Ahaha," Aoko teased, looking down at her sister.

"We're going to have some fun."

"But first," she added, her grin widening, "you need to address me properly. From now on, you'll call me Big Sister Aoko."

"Huh?"

Touko's expression screamed, What is this girl even talking about?!

Aoko didn't bother explaining. With a snap of her fingers, the ropes binding Touko unraveled themselves and coiled neatly to the side.

Finally free, Touko scrambled out of the cloth wrapping her—only to realize she was completely naked.

Her face flushed crimson as she quickly crossed her arms over her chest, glaring at Aoko with a mix of shame and anger. But to her surprise, neither Aoko nor Alice reacted with any embarrassment.

Instead...

Touko hesitated, then lowered her arms and looked down at her chest.

It was flat. Completely flat.

While Touko's figure was never as curvaceous as Aoko's, she was by no means small. Yet now, she found herself utterly flat-chested.

Standing on the carpet, she realized she had to crane her neck to meet Aoko and Alice's eyes.

Touko raised a hand to examine her tiny, tender fingers, and her short limbs. Panic set in as she grasped the horrifying truth—she had reverted to her childlike form.

"What did you make me drink?!" the miniature Touko demanded, grabbing the discarded cloth to wrap herself again. Naked or not, some dignity had to be preserved.

"This is your punishment, Touko," Aoko said, holding up the suspicious glass bottle, its contents now half-drained.

"This was the old man's precious collection. So, how do you like it?"

Touko's face darkened as she mentally pieced together what had happened. She recalled a substance from her extensive knowledge of myths and legends. Could this be the legendary elixir of youth from Mesopotamian mythology?! How did that old geezer even get his hands on something like this?!

"Why would you do this?"

Touko asked, her tiny, delicate face striving for seriousness despite the absurdity of her situation.

Aoko smirked as Alice giggled. Who would've thought Touko could be this adorable?

"Because I think you grew up wrong," Aoko declared with mock solemnity. "It's my fault for not teaching you properly."

She sighed theatrically.

"So, I've decided to become the older sister and re-educate you. I'll help you become a better person!"

This sibling relationship is completely deranged.

Sipping her tea calmly on the sidelines, Alice Kuonji thought to herself, pretending none of this concerned her.

PS: Loli Touko!
