Maki and Mai's daily life was simple and clear.
Go home after school.
Eat after returning home, then head to Toji's dojo.
There, Maki trained.
Mai watched her while doing things like homework.
She also talked with Megumi, who was around the same age.
And she watched the training.
—Who's coming?
—Yeah. Her name is Tsumiki. She moved into our house a while ago. Her mom ran away.
Along the way, she also learned simple self-defense.
Sometimes, she would even cross hands and practice with Maki.
"Welcome back."
When they returned home, the boy who owned the house welcomed them.
The Servants also offered their greetings.
Dependable people on their side.
It was something unimaginable back when they stayed with the Zenin clan.
Doubt vanished, and trust took its place.
As trust grew, so did their affection.
Their affection for the boy they called Oppa was especially strong.
He was kind, and exceptionally good-looking.
He was like someone straight out of an unrealistic drama.
Parent-teacher classes. School trips.
He spared no support for events that required parents.
Normally, people would make appropriate excuses claiming they were busy...
But there was absolutely no need for that.
Especially sports days.
Events that had to be done with family weren't scary either.
A relationship thicker than blood.
The affection built from that grew deeper as time went on.
—What's wrong?
—No. It's nothing. Just felt like someone was watching.
Sometimes they felt like someone was watching them, but...
They just brushed it off and moved on.
The gazes of countless people.
It was because they had gotten used to living in a barrage of all sorts of emotions.
—Necklaces are banned at school, right? Then make sure you carry it in your pocket.
It might have been because of the necklace he gave them, telling them to make sure they carried it around...
They weren't exactly sure.
Anyway.
Maki and Mai grew up amidst affection and worry, consideration and strictness.
About two months into their training with Toji, Raiko intervened.
She taught them even more excellent techniques.
Her sensory training wasn't as good as Toji's, but her techniques were different.
She was far superior to Toji.
Because of that, Toji unintentionally had to suffer.
Because Raiko pushed forward aggressively.
Still, thanks to that, word of mouth slowly began to spread.
It was the result of unintentional advertising.
When people were drawn in, they found the training unique.
It had a sharp edge to it, and the training results were quite good.
Due to the resulting virtuous cycle, the number of beginners increased.
The evaluations were good, too.
People aspiring to be dangerous bodyguards.
People majoring in martial arts. Pragmatists like these came knocking on their door.
Thanks to this, Maki's punching bags also increased.
She built up interpersonal combat experience through fierce sparring.
—No, why is an elementary schooler this strong?
Physical abilities stemming from Heavenly Restriction.
The people who challenged her without knowing that and got torn apart were all shocked.
Every time that happened, Maki laughed, and Mai sighed.
It was thanks to her timid personality slowly changing.
—If you've practiced for 6 years, it's about time you try hunting Cursed Spirits, right?
With humans.
And sometimes by crossing hands with Megumi, she finally entered actual combat.
Two months after they had just entered middle school.
It was around the time the weather was slowly getting hotter.
Maki's aspiration was to be a Jujutsu Sorcerer.
The more exorcism experience she built up, the more helpful it was.
—I'll cheer for you. Tell me anytime if it gets tough.
The boy gave a gift to Maki, who couldn't see Cursed Spirits.
It was a pair of glasses that allowed her to see them.
And he gifted a gun to Mai.
Koyanskaya made both of them, but it was the boy who placed the order.
The sisters received the gifts gratefully.
Mai tilted her head in confusion for a moment, but was soon delighted.
The boy's caring heart.
That heart made her chest flutter.
The supervisor was Toji.
They proceeded with exorcisms slowly, starting from the lowest level, Grade 4.
Sometimes alongside a Jujutsu Sorcerer affiliated with Jujutsu High.
Sometimes they encountered difficulties when running into Grade 1 Cursed Spirits.
Daily life during the day.
Exorcisms at night.
Spending time in these two contrasting lives made the time fly by.
Their school grades were average.
They didn't dwell on grades in the first place.
Because their goal was to be Jujutsu Sorcerers.
Mai didn't like the idea of becoming a Jujutsu Sorcerer, but...
She walked that path because of Maki.
This was a completely different path from the original Mai.
Because it was a choice, not coercion.
—How can they grow that big?
—Oh my?
As the sisters grew, they also began showing interest in their bodies.
The period of awakening to the opposite sex.
It was natural to harbor strong feelings of affection for the boy by their side.
Both Maki and Mai.
Because they wanted to grow to fit the aesthetic standards the boy desired.
The Servants welcomed this.
Surprisingly, even the two Koyanskayas stepped up quite proactively.
Eventually.
The sisters grew significantly, and the body of a certain boy also finally became an adult.
It was summer.
Ah, I'm sleepy.
Zenin Maki briefly took off her glasses and rubbed her eyes.
The afternoon sunlight coming in through the window.
The quiet air was warm and boring.
"Maki. Mop over there."
Mai muttered as she swept with a broom.
The sisters, Maki and Mai, were on cleaning duty this week.
"Yeah. Got it."
Maki put her glasses back on and wiped the floor with a mop.
Sweat trickled down the sisters' napes.
The sweat passed their napes and went beneath their large breasts that seemed ready to burst through their school uniforms.
It seeped into the deep, deep cleavage.
Zenin Maki.
And Zenin Mai.
The sisters, who were beautiful even in their faces, naturally drew attention.
Men, and even women.
There were many cases where they received confessions regardless of gender.
There were some unsavory incidents during that process, but...
They solved them with wisdom and military force (physical strength).
"Maki, are you going to the gym again today?"
Mai asked while putting the broom away.
At some point, she naturally started calling her by her name instead of Unni (older sister).
Her timid personality had also changed.
She was insidious yet cynical, and proactively submissive to a certain someone.
"No. I said I'm taking a break today, so I'm going home."
On the other hand, Maki wasn't much different from when she was young.
She was refreshing and bold.
Even if someone stared openly at her chest and butt.
Even if they took out their misplaced anger on her, claiming they broke up with their boyfriend because of her, she embraced them.
The woman who took her anger out on her was even the school nurse, but...
She had repented after experiencing Maki's paternal love combined with maternal love.
"That's good. Miss Koyanskaya told me to go grocery shopping, so I thought there'd be a lot to carry."
"Which one?"
"Of Light. She said she's cooking Russian food, so we're stopping by a big supermarket."
"Russian? Is it borscht or something?"
"Who knows? We'll find out when we buy the ingredients. Anyway, carry some bags for me. I'm delicate."
Mai, having finished cleaning, stuck closely behind Maki.
Her large breasts squished softly against her.
Maki nodded as she looked at Mai clinging to her.
That much was nothing.
"But, if we were going grocery shopping, why didn't you just say so? What would you have done if I just went to the gym?"
"What's the point of taking you when your mind is distracted by training? I was going to do it alone."
"Go alone and curse me out?"
"Oh my. How did you know? I was planning to whine to Oppa that Maki didn't help me."
"I just figured you would. Anyway, let's go. Cleaning's done."
"Yeah."
The sisters finished tidying up and left the classroom.
The beautiful sunlight was dazzling.
'It's so peaceful.'
Mai blinked as she looked at the sunset.
A nightmare she had a while ago kept flickering in her mind.
A future where she was forced to become a Jujutsu Sorcerer.
After all sorts of incidents, the situation got tangled, and her biological father tried to kill her.
The end of it.
Even the future where she threw away her life for Maki, who was locked up alongside her in a punishment room swarming with Cursed Spirits.
It was too vivid to be a mere delusion.
And too bitter to be called a prophetic dream showing the future.
"What are you thinking about?"
Maki, who was walking beside her, asked.
Just by looking at Mai's face, she knew exactly what emotion she was feeling.
It might be hard for others to tell, but Maki was different.
Because she was her older sister.
'Honestly, she notices things like this like a ghost...'
Mai pouted her lips for a moment.
Her stomach twisted at her sister's still cool and beautiful appearance.
She liked it, but also found it aggravating.
As they grew, their emotions became richer and more complex.
"Nothing. Just thinking about the nightmare I had a while ago."
"Ah. That? Isn't it just a nonsense dream?"
Coincidentally, Maki had the exact same dream.
The self in the dream lacked her current volume and was covered in burn scars.
Just like a rag.
However, that kind of thing wasn't the issue.
Mai's death.
The terrible sense of loss caused by it was too unpleasant and sticky.
So she paid a little more attention to Mai.
She had no choice but to.
"That's true, but it was strangely realistic. So I just... can't forget it."
"Keep trying and forget it. It's just unpleasant."
Family dying.
For Maki, it was something she had never imagined.
She wasn't particularly afraid of dying herself.
But just imagining Mai dying was thoroughly unpleasant.
"Let's stop talking about that. We have something important coming up."
"Something important?"
Mai blatantly changed the subject.
It was exactly what Maki wanted, too.
So when she showed interest, Mai's eyes widened.
"Don't tell me, you forgot? It's Oppa's birthday soon. And it's the day he properly becomes an adult this year?"
"Ah, right. I didn't forget."
Maki hurriedly shook her head.
She just didn't know what the 'important thing' was.
"As long as you didn't forget."
Mai let out a long sigh.
Fortunately, there was no sign she was lying, so she felt relieved.
"Anyway. It's a special day, so we should give him a gift. Don't you have any good ideas?"
"Uh... something like panties?"
Maki hesitated for a moment before asking.
Because she lacked the sense to choose gifts, her ideas were poor.
"...You're such a pervert."
Mai said with blushing cheeks.
Even though she thought it was vulgar, she felt a strong pull toward the idea.
Did he wear the underwear I gave him today?
This thought naturally popped into her head.
"Hey. You're way more of a pervert than I am. Even just yesterday..."
"Stop. Right there."
"Ahem. Got it."
When Mai frowned, Maki hurriedly shut her mouth as well.
A heavy and awkward atmosphere flowed for a moment.
"Haa—. Anyway, think carefully about a gift. Actual panties seem a bit off."
"I know. I was just joking too."
Maki sighed and nodded.
She had survived for now.
Having narrowly escaped death, her mind felt at ease.
Her intensely spinning head slowly cooled down.
