"Miss Sakura, Miss Fuyuka, there's something I'd like to ask of you."
"Tsubaki, we're family now. Just say it," Miyajima Sakura replied warmly.
Now that they were calling each other by their first names, the bond between the three girls had grown much closer.
"I want to learn kendo from both of you."
After undergoing her evolution and transformation, Rurikawa Tsubaki made this request later that same night at the hospital. Neither Tosaka Fuyuka nor Miyajima Sakura refused.
They both understood why she wanted to become stronger. That was why she had taken the initiative to learn kendo. Yet despite her already astonishing strength and physical abilities, she still wasn't satisfied.
Rurikawa Tsubaki wasn't dissatisfied because she thought she was still too weak. Her current superhuman body was already more than enough for revenge. The real reason she wanted to learn was to repay Kazuma.
Miss Maid's heart was overflowing with gratitude for the power her master had given her.
Even though it had been a transaction, after experiencing the transformation firsthand, Rurikawa Tsubaki understood just how extraordinary it was. Even if everyone in the hospital pooled their resources together, it still wouldn't have been enough to obtain something like this.
Could such power really belong to her?
The first and most obvious change was her physical recovery. The chronic fatigue and poor health caused by overwork, part-time jobs, and constant frugality had completely vanished. According to Sister Amamiya's examination, her strength, speed, and every other aspect of her physical condition had surpassed normal human limits.
Her five senses had also improved dramatically. To put it simply, her eyesight was now comparable to that of a hawk.
But what shocked Rurikawa Tsubaki the most was her brain. She discovered that her mind now operated with efficiency rivaling a supercomputer. Her information-processing speed was astonishing, and her memory had become nearly perfect—anything she saw once, she could remember.
I was pursuing strength, so why did my brain evolve too?
Using her newly enhanced cognitive abilities, Rurikawa Tsubaki quickly arrived at a conclusion.
"Is it because of this incredible learning ability?"
She had discussed it with Tosaka Fuyuka. Miss Fuyuka's brain had also evolved, granting her photographic memory, but even she couldn't compare to Rurikawa Tsubaki. The difference became clear very quickly.
"Are you kidding me?"
Miyajima Sakura checked the time on her phone. It was nearly eleven at night.
"In just one hour... one single hour, she achieved what took me six years in kendo—no, she's already surpassed it."
What kind of absurd story is this?!
"It's not just you," Tosaka Fuyuka said with a serious expression. "Her kendo has already surpassed mine as well."
In terms of raw physical strength, Rurikawa Tsubaki was still inferior to Tosaka Fuyuka. They had already tested that through arm wrestling, and Fuyuka's strength was truly monstrous. However, she didn't possess Tsubaki's overwhelming learning ability. It was as if Rurikawa Tsubaki had been born for the sword.
But that couldn't be true, because before today, she had known absolutely nothing about kendo.
With every swing of her sword, she used her extraordinary mind to analyze and correct her movements. Each strike became more refined than the last, and after only a dozen swings, no flaws could be found.
Within that single hour, she had completely absorbed the swordsmanship of both Miyajima Sakura and Tosaka Fuyuka. She could even analyze their techniques and devise counters to them. If Rurikawa Tsubaki had a proficiency system, she would have seen the numbers rising by thousands—perhaps even tens of thousands—every second.
New skill acquired: [Kendo]
Soon, Rurikawa Tsubaki was able to suppress her opponents during their kendo sparring matches. That flawless, impeccable performance left the two kendo girls deeply discouraged.
"It feels like facing a robot."
"What robot? That's called AI."
Impeccable movements, impeccable swordsmanship. Even Tosaka Fuyuka felt a little deflated. "Tsubaki, you're terrifying. How did you develop such monstrous learning ability?"
She was aware that her own learning ability had also improved, but it wasn't nearly as exaggerated as Rurikawa's.
"I'm not sure either..."
But it was definitely because of the evolution.
Late at night, Rurikawa Tsubaki wasn't resting. She was in her room, flipping through books she had found in the hospital. With her ability to read ten lines at a glance, it wasn't long before a thick pile of books had accumulated on the table like a small mountain.
Miss Maid seemed to have no desire to sleep at all. After finishing the books, she headed to the cafeteria to try cooking.
As a young lady, she naturally had never learned how to cook. Even after the Rurikawa family had fallen, she had lived on cheap bento boxes and instant noodles. Cooking for herself had been out of the question. But this time, without anyone's guidance, after spending two hours in the kitchen, she perfectly recreated the gourmet dishes from the book.
Acquired new skill: [Culinary Arts]
If cooking didn't require so much time, she might have mastered it even faster.
After learning cooking, Miss Maid began training in martial arts. The hospital library had books on that as well. Although she had no teacher, she could still feel her proficiency rising rapidly, no slower than her kendo.
Paired with her completely renewed body, it was like adding wings to a tiger.
What others considered precious epiphanies or flashes of inspiration had become normal for her. In the face of her super brain, there were no secrets; everything came naturally.
"Without comparison, I don't know exactly how strong I am now," Rurikawa Tsubaki said, looking at her fair, delicate fist after punching a crack into the wall, deep in thought. "Probably... not weak, right?"
It was as if she had been equipped with a supercomputer chip. Those techniques and movements were impossible to forget even if she tried. Usually, even when the brain learns something, the body doesn't necessarily keep up. But Rurikawa's physical abilities perfectly matched her brain, like hardware designed for a top-tier processor.
The Evolution Ray obviously wouldn't leave behind such flaws.
"I've completely mastered it..."
Acquired new skill: [Martial Arts]
Young Lady Rurikawa seemed to have found a fascinating new toy. This rapid learning ability made her eager to experience more new things and master more skills.
The girl wasted no time, taking the elevator down to the underground warehouse. She took out the firearms stored there.
Although there was no manual, there were plenty of videos online.
However, she didn't look for tutorials. Instead, she figured it out herself. After assembling and disassembling the weapon a few times, her terrifying brain quickly grasped its structure and functions. After a brief pause, she attached a suppressor and began practicing in the basement.
Bang—
Bang! Bang! Bang!
Just starting out, her first shot didn't even hit the target. For a girl with hawk-like vision, that could only be considered embarrassing. But from the second bullet onward, her movements quickly adjusted, and her body became increasingly coordinated. That terrifying, top-of-the-line CPU was already at work.
Bang! Bang! Bang! Bang! Bang!
The points of impact began to cluster together, then gradually tightened around the bullseye. By the time Rurikawa Tsubaki had fired five hundred rounds, there was only a single, deepening hole in the center of the target.
They say sharpshooters are made one bullet at a time, but Rurikawa Tsubaki clearly shattered that notion. From complete novice to mastering a Beretta and scoring one hundred bullseyes at fifty meters, it had taken only ten minutes and five hundred rounds.
Could this be any more unbelievable? Was she a monster?
Was this the terror of an evolved brain?
Acquired new skill: [Firearms]
"Is it morning already?"
Rurikawa Tsubaki emerged from the basement and suddenly froze. The sunlight made her squint, and she raised a hand to shield her eyes. Without realizing it, she had spent the entire night learning.
Culinary arts, housework, kendo, martial arts, firearms—in just one night, she had reached the pinnacle of mastery in all of them.
"Now, I should finally be qualified to be a maid..."
If maids around the world heard that, they might just cry from shame.
"Young Lady, you didn't rest?" Nurse Kurokawa, who had just woken up, saw Rurikawa Tsubaki stepping out of the elevator and was immediately shocked. "You stayed up all night?"
"Mm, I did a bit of studying," Rurikawa Tsubaki replied, clearly in a good mood. Her tone was light and cheerful. "After all, I'm a maid now. I can't be too lazy. It's fine—I still feel great."
This was perhaps another change brought about by evolution.
Nurse Kurokawa had no idea what incredible achievements her young lady had accomplished overnight. She grinned mischievously. "Why work so hard, Young Lady? To be a good maid, you only need to do one thing well."
"What?"
"Of course, it's s-e-x. As long as you can satisfy the master in that aspect, that's enough," she made a lewd gesture, giggling. "Only a maid who can satisfy the master with her body is a truly good maid."
"..."
Rurikawa Tsubaki paused, then looked a little embarrassed. How could she have forgotten? Of course, she didn't regret anything. After all, her master had said he didn't need a mere pretty face. Learning more skills would allow her to be more useful to him.
But what Kurokawa said was also right. If she could make him comfortable and satisfied physically, it would be even better.
Besides, there was still their agreement.
Miss Maid lowered her head and looked at her flawless, perfect body. Originally, she hadn't cared much about the enhancement to her beauty and charm. But now... compared to the evolution of her mind, she felt that charm was equally important.
The master would probably like that more, right?
Rurikawa's perspective had clearly changed. If before it had only been about fulfilling their agreement, now she genuinely wanted to repay him.
"He hasn't even taken my body yet, hasn't taken my purity..." This made Rurikawa increasingly worried and uneasy. "Maybe I should learn about those things first?"
"Kurokawa, do you have those... those lewd websites?"
"Young Lady, why look at those? If you want to learn, firsthand experience is better," Kurokawa whispered close to her ear. "Our boss hasn't woken up yet, Young Lady. Why not go try?"
"Okay!"
Kazuma was sleeping in the hospital.
Rurikawa Tsubaki came to a room on the top floor and saw Kazuma sleeping soundly inside, as comfortable as if he were at home. She slowed her steps and carefully walked in.
Full of energy so early in the morning.
The beautiful maid stood gracefully by the bedside, gazing at the towering, massive object. Her cheeks flushed, and her heart pounded like a startled deer. "Helping the master relieve stress is also part of a maid's work... it's my duty."
The former Rurikawa Tsubaki was a blank sheet of paper. And now, this sheet of paper was about to be dyed with Kazuma's colors.
"Master..."
