Mid-June. During the humid and depressing rainy season, Cursed Spirits and Curse Users alike welled up like maggots.
In the midst of this, Naoya, having negotiated with Masamichi Yaga to undertake a Grade 2 Cursed Spirit subjugation mission, was currently visiting an abandoned building somewhere in Tokyo, accompanied by his disciple Mai Zen'in and her older sister, Maki.
"Ugh..."
"Mai-chan, I know it's embarrassing. But your Cursed Technique is based on a Binding Vow. You can't fight unless you steel yourself and transform."
"Mai! Do your best! I'll fight with you!"
"But you don't transform, Big Sister...!"
"We have matching dresses, don't we!?"
As their exchange suggested, the precocious twins were reaching the age where playing magical girl was starting to feel embarrassing. At roughly four and a half years old, entering a slightly early rebellious phase, they had realized, 'Wait, isn't this a hobby for little kids...?' and were feeling fidgety about wearing the dresses.
However, Naoya's words were also a fact. In exchange for tremendous Cursed Energy output during transformation, Mai was forbidden from using Cursed Energy and her Cursed Technique normally. The trigger for this was set to be the transformation dance and the transformation catchphrase.
"Just transform quick, exorcise it snap-snap, and it'll be a breeze."
"But, but... Naoya will hate me..."
"What's that about? I won't hate you. What's wrong?"
While gripping the Cursed Spirit's head with one hand and keeping it 'Frozen', Naoya listened to the whimpering Mai. Apparently, her worry was that 'Naoya likes adult women with big breasts, so he'll hate me for being childish.'
Inwardly, Naoya thought, 'Why does Mai-chan like me so much? Have her eyeballs rotted out and the poison reached her brain? Or rather, don't worry about it; no matter what you do, you're a piss-smelling brat, so you're out of the question anyway. I thought this from the bottom of my heart when Utahime-chan clung to me the other day, but I don't even want to date anyone under an H-cup. Well, being waited on by cute girls feels good, though. I'm picky about my wife.'
Despite these thoughts, they never left his mouth. Instead, what came out was a gentle tone.
"Mai-chan, you don't need to worry about that. Where would you find a master who doesn't cherish a disciple working hard to become a sorcerer?"
Told this, Mai finally steeled her resolve.
"Turning everyone's feelings into power! Magical Mai-chan, Make-uuup!"
Roaring with an intensity that made one think it was the series finale, she began fighting the Grade 2 Cursed Spirit Naoya had released, alongside Maki. Although there was some struggle, they achieved victory without any real danger using the sisters' combination attack, 'Twin Magical Mai-chan Vanish'.

A while after returning from the Cursed Spirit extermination training.
Naoya quickly returned to his own dorm room, while the twins were enjoying a secret conversation in one of the rooms in the faculty dorms rented by Toji.
"Ah, today was scary too..."
"Really? You blew it away perfectly, didn't you, Mai? The Cursed Spirit's movements were slow too."
"That was just for you, Big Sister! My eyes are normal!"
"Is that how it works?"
"It is! ...But, at this rate, Naoya will definitely be taken by you, Big Sister... I have to work hard."
"No, why? We'll just be the two of us together normally. The old man said so too. Besides, I feel like Naoya is just 'Big Bro'. I like him, though."
"Books say that kind of girl is the most dangerous one! Ughhh...!"
"Don't growl, are you a dog...? What books?"
"The ones I got at the school store! This!"
What Mai held up as she claimed this was a three-piece set of girls' and women's manga magazines: 'Chorus', 'Ribon', and 'Margaret'.
As to why the rather adult-oriented 'Chorus' was there, one could only say it was for the female students who used the school store normally. If anything, 'Ribon' was the lineup added starting this fiscal year specifically for Maki, Mai, and Tsumiki.
Armed with these somewhat unreliable bibles, Mai seemed fired up about monopolizing Naoya... but Maki, who was supposed to be a fiancé as well, didn't seem to be thinking too deeply about it.
"Well, it'll be fine. Mom has big boobs. Ours will probably be big too. Naoya likes boobs, right?"
"That's true but... but they probably have to be as big as Mei-chan or Yuki-chan or it's no good..."
"Hmm, I don't know any way to make them bigger... Should we ask an adult?"
"An adult woman..."
---
"So that's why you came to ask me. I see. Well, generally speaking, once you hit puberty, maybe wear a night bra, avoid unreasonable diets, and make sure to take in enough fat?"
Giving this answer amidst the steam was the only female student among this year's Jujutsu High students, Shoko Ieiri.
Due to the locking up of the women's bath, she often bathed together with the twins and Tsumiki, settling into a bit of an older sister position.
Asking her was, in a sense, the correct move. Although lately she had gained the image of a gunner who blasted away recklessly, her main profession was that of a healer. She was quite strong when it came to questions like this.
Then, she suddenly voiced an idea as if it had just occurred to her.
"Hmm, what else? I don't have proof, but... maybe using Reverse Cursed Technique to gather 'positive' energy in the parts you want to grow during puberty? Look, Gojo, Geto, Naoya, and even Nanami are all huge. And Special Grade Tsukumo-san and Grade 1 Mei-san have amazing figures too. I think that's probably the influence of body reinforcement via Cursed Energy, but if you did that with Reverse Cursed Technique, wouldn't it probably be amazing? I don't know for sure, though."
"Reverse... Cursed Technique..."
"Yeah. You go hyuun and then pop. You multiply Cursed Energy with Cursed Energy to convert it into positive energy. It might be worth a try? I won't do it since having a chest would just make my shoulders stiff, though."
The casual remark Shoko made while laughing would go on to plant an insatiable obsession with Reverse Cursed Technique in the heart of the girl aiming to be a Jujutsu Sorcerer. But for now, no one other than the person in question realized that fact.
