In the bathroom, Yuu Hoshimiya gazed at Mary with eyes full of smiles.
The vibe she gave off was incredibly similar to Ai Haibara, though she was much more voluptuous than her niece.
Especially that slight furrow in her brow—it was exactly the same as Ai's.
Genetic lineage is truly powerful.
I should find a time for them to meet after the contract is finalized.
Yuu thought to himself while continuing to drive into her with effort.
The first two conditions for the contract had actually been met, but just as he suspected, one of the long-cherished wishes in Mary's heart couldn't be fulfilled yet.
Mmm, that's right; there were two deeply rooted obsessions in her soul.
This was the first time Yuu had encountered such a situation, and while surprised, he accepted it quickly.
After all, there was no rule stating a person could only have one soul's desire.
It's just that for most people, there is only one desire deep enough to count.
But for Mary, reverting to her original body and dismantling the Black Organization were equally important and equally deep-seated.
The first was relatively simple; Yuu actually had a way.
The perfected version of APTX that could provide true eternal youth wasn't finished, but the antidote had already been successfully developed.
However, the second wish would still require some time.
But not too much longer.
While Yuu worked hard to improve his own strength, Angel's Wing and Noah were executing various missions according to his will.
The development of APTX nineteen years ago, the true identity of the Organization's Boss and his relationship with Vermouth...
The experimental data left by the Miyano parents and the truth behind their "accident"...
The investigations into Rumi Wakasa and Hyoue Kuroda, the infiltration into the FBI and MI6, the true identity of Rum, and the status of his base on the isolated island...
With the intelligence provided by Yuu as a roadmap and Noah's "dimensional-crushing" hack-investigations, the truth was slowly surfacing.
Just like the research on APTX, the progress was slow, but it was moving forward.
When the progress hit 100%, Yuu would move to end everything.
With his current magical level and inhuman physical stats, supplemented by Noah's assistance, no person or power could stop him if he chose to act.
As the peak of ecstasy subsided, Yuu pulled back his wandering thoughts and refocused on the person and the moment before him.
It was a pity he couldn't contract Mary yet, but that didn't stop him from enjoying himself to the fullest.
This was only the first round, and its main purpose had been to see if the contract could be completed on the spot.
Mary's petite, snow-white feet couldn't reach the floor, dangling and swinging in a way that looked incredibly playful and cute.
Yuu's large hand settled on her waist as he leaned in to capture her lips once more.
Mary responded uncontrollably, her emerald eyes overflowing with affection.
Then, Yuu lifted Mary up into a carry.
Mary's youthful, slender body was truly jarring in its lack of coordination compared to Yuu, who was now nearly 190cm tall.
She didn't weigh much, and combined with Yuu's monstrous stamina, carrying her around was effortless.
He even had ways to keep her "flying" in the air indefinitely.
Soon, however, he had Mary stand before the washbasin and the mirror.
Mary was too short, so she had to stand on a small stool, with Yuu standing behind her, holding her slender waist.
Looking at Mary in the mirror—her shy, aroused expression made Yuu's entire body tingle.
His large hands firmly gripped her waist, beginning a series of powerful, rhythmic thrusts.
By looking down, he could see the golden-haired, busty middle-school beauty's perky buttocks rippling with every impact from his hips.
"Mary, look at your expression. You look so slutty."
Mary looked at her own reflection and found the shame almost unbearable.
Her small hands pressed against the edge of the sink as she involuntarily lowered her head.
The smile on Yuu's face was wicked, as if he were recalling something amusing.
He cupped Mary's small face, tilted her head, and kissed her deeply.
In the living room, seeing that quite some time had passed, Masumi Sera planned to go see how her mother's "treatment" was progressing.
Walking to the bedroom door, she was about to knock when she suddenly smelled a strange scent.
It was an indescribable smell, but definitely not pleasant.
It was the residue from Mary's "marrow-cleansing"; those bedsheets were a lost cause.
Masumi Sera grew tense instantly, thinking something had happened to her mother.
She didn't knock, choosing instead to try and open the door directly.
Yuu hadn't locked it, which made things easier for her.
Entering the room, the girl saw no one, but just as she was panicking, she heard sounds coming from the ensuite bathroom.
She crept over and pressed her ear against the door.
In an instant, her expression changed completely.
Because from inside came her mother's cries—sounds that seemed to be a mix of pain and pure joy.
Is Mom sick? Thinking this, Masumi grew anxious.
Just as she was about to knock and ask, she heard Yuu's voice, and for a moment, she was dazed.
What's going on? Is Teacher Hoshimiya treating Mom?
Then why are they in the bathroom?
And Mom's voice doesn't sound like she's being treated... Is she having SEX with Brother Yuu?
My god, no... what am I thinking? Mom looks like a child right now...
Teacher Hoshimiya wouldn't make a move on a child, would he?
Even if he did, Mom would fight back.
Recalling the foul smell on the bed, she thought maybe Brother Yuu was helping her mother bathe.
But why would Mom let him bathe her? Is it really like that?
Otherwise, who makes such erotic sounds while bathing?
How could Mom do this? Should I stop them?
What if I'm wrong? How would I face Mom or Teacher Hoshimiya then?
Caught in a dilemma, Masumi could only keep her ear pressed to the door, listening intently, trying to find evidence that would debunk her own deduction.
Hearing those seductive sounds, Masumi's breathing became ragged, her face flushing red.
She wanted to keep listening, but it sounded like her mother and Teacher Hoshimiya were about to come out.
Seeing this, Masumi hurried back to the living room.
Closing the door softly, she pressed herself against it to listen to the outside.
Ran was curious about her behavior and was about to ask what was wrong when she received a message from Yuu on her phone.
After reading the message, she let out a helpless sigh. She ignored Masumi peeking at the door and walked straight to Narumi Asai's room.
After reading the text, she knew she wouldn't be sleeping with Yuu tonight; she'd either sleep with Narumi or go back to her own long-vacant room next door.
After a moment's thought, Ran decisively chose to sleep with Narumi.
Back with Yuu, after telling Noah to message Ran, he picked Mary up and opened the bathroom door.
He thrust into the enticing beauty in his arms with every step, burying his length deeper and deeper.
Mary clung tightly to Yuu, staring at the bedroom door, her small hand covering her mouth for fear she would let out a scream that her daughter might hear.
Yuu looked at Mary's current state, then glanced toward the door, his lips curling into a smirk.
Then, he began to work even harder!
With the sound of a door closing, Masumi saw Ran go into Narumi's room. Though she didn't know why, she felt emboldened.
She looked at the closed bedroom door, pondered for a moment, and finally turned the handle slowly, opening the door a tiny crack.
This time, the sounds became crystal clear.
The scene of unlimited spring-time eroticism inside was fully captured by the girl through the finger-width gap.
As expected... those are moans of pleasure...
Mom really is having SEX with Teacher Hoshimiya.
Even though Mom has become so small, it's actually possible?
Staring at the erotic display in the room and hearing her youthful-looking mother's whimpers, Masumi couldn't help but clamp her legs together. Her face was bright red, her eyes misted over, and she began to pant slightly.
She saw a tall, handsome young man pinning down a 140cm-tall blonde, busty middle-schooler, performing primal movements.
That thick, long weapon kept driving into the petite foreign beauty's small cunt; it was a mystery how she could even contain it.
Mary whimpered non-stop while Yuu thrust his waist, his hands kneading her "jade rabbits" simultaneously.
Watching the white, soft flesh being molded into various shapes in his hands, Yuu became even more excited.
...
During the intermission, Mary—with her incredibly sharp observational skills—noticed Masumi peeping and masturbating outside.
However, mother and daughter shared a silent understanding; neither called the other out. They simply pursued their own pleasure across that narrow gap in the door.
When her second masturbatory climax ended, Masumi silently closed the door and dragged her aching body back to the 28th floor alone.
Once her daughter had left, Mary became even more uninhibited.
She had been empty for so many years, and now her body was completely healed by Yuu—in peak condition, her "combat power" was formidable.
That night, Mary's stamina was exceptional, only slightly inferior to Ran's.
This allowed Yuu to play to his heart's content, launching an all-out offensive that left the durable Mary utterly defeated.
Honey-juices sprayed everywhere, making Yuu's eyes glow with excitement.
That night, Mary was hammered by Yuu in every conceivable position until her eyes rolled back. Her petite, soft body was twisted into various shapes for his output.
An "enchanted" Yuu was even more ferocious, forcing Mary into continuous retreat as she climaxed over and over.
Finally, he only let her go once she pleaded for mercy.
The next morning, in a side room of the Suzuki Manor, Curacao finally woke up on the bed where she had been unconscious all night.
But Curacao didn't open her eyes immediately. Instead, she tried to sense if she was injured or restrained, listening intently to her surroundings.
She was staying still, waiting for an opportunity to strike and escape.
Suddenly, two fingers propped her eyelids open, forcing her eyes wide. Her pupils were a bit dazed from the sudden light.
Beside her, Kimie Shimabukuro couldn't help but speak up: "Yuu-kun, why are you poking her eyes for no reason? How rude!"
Yuu Hoshimiya chuckled and said, "Shiro-chan should be awake by now. I saw her little movements."
Hearing that familiar voice, Curacao immediately turned her head. She saw the smiling Yuu beside her and a girl dressed in a miko (shrine maiden) outfit.
Realizing she was in a room that was low-key yet luxurious, she was momentarily confused.
What's going on? why am I here?
Memories of last night began to flood back.
Right... the explosion!
The people from the Organization lured her into the Ferris wheel and then detonated a bomb to kill her!
"Shiro-chan, the Ferris wheel exploded last night. I barely managed to save you. How are you feeling now? Any discomfort?"
As Yuu spoke, he introduced the girl beside him.
"Shiro-chan, this is the person who brought you back to the Suzuki Manor last night. Her name is Kimie Shimabukuro."
"She is a real miko. She's the one who looked after you and used magic to treat you."
The "Witch Squad" with supernatural aptitude was currently still in Japan, helping Yuu handle Organization-assigned tasks and other matters.
After all, magic is very convenient and useful.
Kimie Shimabukuro was the one who had whisked Curacao away last night.
Kimie waved her hand shyly.
"It was nothing. I'm just an entry-level miko; my healing magic works only half the time. It was Yuu-kun who came by this morning and treated you again properly."
What the hell? Miko? Magical treatment?
What are these things?
Why are they talking about this with such casual tones?
Has the world changed that much, or have I been unconscious for too long?!
Curacao's brow twitched involuntarily.
Seeing her expression, Yuu feigned hesitation and asked, "Shiro-chan... you... did you get your memory back?"
At this, Curacao realized her shocked expression had made Yuu suspicious.
She instinctively played dumb: "I still can't remember anything. Kimie, hello!"
Curacao even sat up and shook Kimie's hand as if they were meeting for the first time.
Yuu acted as if he had let out a sigh of relief.
"Shiro-chan, this Suzuki Manor is also my territory. I originally planned to have you stay at my house, but since your memory isn't back, the constant coming and going of people there isn't good for recovery."
"So I decided to settle you in this quiet manor first. The environment is better, and with Kimie and the others here, it's very safe."
The highly-trained Curacao had incredible adaptability. Her superhuman brain worked rapidly, quickly analyzing the situation.
The bomb last night had been massive—a guaranteed death sentence—yet Yuu had saved her and she was unharmed. That was proof enough of his power.
In her current position—purged by the Organization and hunted by Public Security and the FBI—she was the center of a storm.
Resting here was an excellent choice.
But as for magic...
While Curacao was still hesitating, the words of Yuu and Kimie finally dispelled her doubts.
Yuu knew what Curacao was worried about. While playing the "amnesia game" was fun, if she decided to leave alone to avoid "burdening" him, it would be another huge headache.
So it was better to lay everything out now—including the truth about magic and his own situation—to completely remove her concerns.
Yuu's situation was complex, involving APTX and the Organization's core secrets. Combined with proving the existence of supernatural power, the explanation took a full hour.
"Shiro-chan—or rather, Curacao—take some time to process this. I have things to do at home. I'll be back tonight."
Yuu and Kimie left for now, leaving the room to the Nordic beauty, who was currently cycling through states of shock, confusion, and doubt.
The information dump was massive; even Curacao needed time to adapt and accept it.
Once she accepted it, she'd need more time to make a choice: whether to go or to stay.
Yuu felt Curacao would likely stay, but the words had to come from her own mouth.
At ten in the morning, Yuu returned to the tower apartment.
Mary was still sleeping peacefully, wearing one of Yuu's oversized T-shirts.
Her fair, short legs peeked out from beneath the shirt, looking adorable.
Under her golden curls was an exquisite, serene face, like a porcelain doll.
Yuu climbed onto the bed, leaned down to kiss Mary's porcelain skin, and spoke softly, "Mary, time to wake up. The sun is hitting your butt."
Mary's long lashes fluttered as she slowly woke from her dream, but her body felt exhausted, and she didn't want to wake up just yet.
She hadn't slept this soundly in a very long time.
Previously in hotels, she and Masumi always slept very lightly.
The moment someone knocked, they would hear it and wake up instantly.
Sometimes it was just room service; other times it was actual assassins from the Organization, requiring them to flee without a moment's notice.
She could never sleep as soundly as she had today, without a single worry, not even feeling a hint of danger with someone so close to her.
Yuu leaned down again and kissed her once more.
This time, on her pink lips.
"Mary, if you don't get up, breakfast is going to get cold."
Mary finally forced her eyes open, her gaze full of daze like a tiny kitten.
Seeing it was Yuu waking her with a gentle voice, her lips couldn't help but curl upward.
She then wrapped her two short arms around Yuu's neck.
Yuu reached out and lifted the lazy loli into his arms.
Feeling Mary's softness pressing against him, Yuu grinned wickedly. "Does Big Brother need to 'treat' Mary again like last night before you'll get up?"
"Dame! Absolutely not!"
Mary was instantly wide awake. She knew exactly how powerful Yuu was—a full four hours—another round would be the end of her.
She shot Yuu a glamorous look with her emerald eyes; that look was truly similar to Ai's.
Yuu carried Mary toward the dining table.
Mary wasn't used to being looked after like a child; her body twisted and struggled as she tried to get down.
After Yuu gave her a few firm slaps on the butt, she finally settled down with a red face.
In the end, Mary resigned herself to fate, sitting on Yuu's lap with a flushed face while he fed her breakfast, occasionally enduring the wandering of his large hands.
Yuu's hands slid into the sleeves of her T-shirt, holding her body.
He then spoke in the tone used to trick children.
"Mary, everything Big Brother did to you last night was to treat your body. It's a special form of therapy—Big Brother's unique secret technique. It can't be known by others, so you have to help keep the secret, okay?"
Hearing this, Mary couldn't help but roll her eyes, turning to look at Yuu with disdain.
What kind of 'unique secret technique'?! Do I look stupid? Do you really think you can trick me like a child?
Why does this feel exactly like a principal tricking an elementary student into 'looking at goldfish'?
Then Yuu wore a look of distress.
"But Mary, you need to explain things to your 'sister.' She was eavesdropping for so long last night; she might misunderstand."
"Just tell her this time was special, which is why the treatment took so long. Tell her not to think too much about it."
Hearing this, Mary finally remembered her daughter peeping at the door last night.
She had been too immersed in the pleasure to care or try to hide it.
Now that she recalled it, she panicked instantly.
How will Masumi look at me from now on?
The fake blonde middle-schooler had no energy left to complain about Yuu's attempts to "trick a child"; she looked utterly despondent.
Her mind worked at top speed, wondering how she would face her daughter.
Yuu looked perfectly calm, not thinking it was a big deal at all.
He had no intention of letting that cute "snaggletooth girl" Masumi go; it would be even better to have mother and daughter together later.
Seeing Mary in deep thought, he returned to feeding her breakfast.
Mary's "combat power" was only a notch below his "Little Angel," which had made last night's battle exceptionally satisfying.
It made sense; before her body shrank, she was a top-tier agent.
"The Sister from Outside the Domain." Domain is "territory" (ter), and "Sister" is "sister." Removing "ter" from "sister" leaves "SIS."
The UK's MI6 (Military Intelligence Section 6), also known as the Secret Intelligence Service (SIS).
In other words, Mary was an MI6 agent, from the same place as Stout.
Her physical stats had been immense; before shrinking, she could fight Shuichi Akai to a standstill.
Added to the fact that she had undergone "Marrow-Cleansing" via Yuu's electrical magic last night, her body was fully restored and even more powerful.
But no matter how powerful she was, she still had to plead for mercy from Yuu in the end.
Holding the golden-haired, busty middle-schooler, Yuu finished feeding her breakfast, gave her butt a light pat, and sent her off to wash up.
