Chapter 139 Winter Vacation Countdown


Edited by: Kanaa-senpai


 ”Be… uh… beautiful?… So… uh… Master Aki?… Sayuri… Sayuri is going to be killed by you… uh… you’re so… amazing… making me again… ah… oh… losing it again?… hmm… you… how could… how could you be this amazing… ah?… so good?… my whole body… is flying… really… really feels like heaven… uh… good Master… good brother… you… you reached my flower heart?… ah… it feels so good…” Sayuri moaned, trembling under Aki.


 The bedroom was filled with the colors of spring. Lying beneath him, Takamine Sayuri trembled delicately, her fragrant sweat flying like rain. Her moans were continuous, each word filled with sweet satisfaction.


 Aki remained still, holding the slender, wet waist of the purple-haired girl with one hand. He let her twist freely, the sweet scent of her body mingling with her sweat, filling the room.


 She had no idea how long she had been like this in Aki’s embrace. Her whole body felt numb, and deep within the Flower Palace (Hanamiya)¹, another wave of sweet tremor surged, releasing another stream of delightful Yin Essence².


 The unprecedented pleasure struck her entire body. It felt as if every inch of her flesh was filled with joy, leaving nothing else behind.


 Yet Aki, far from being overwhelmed, had unknowingly started transmitting faint suction from the tip, as if wanting to absorb all of her essence.


 The sensation made Takamine Sayuri even weaker, unable to resist.


 She could not help but moan coquettishly, as if her whole self had melted into the ecstasy.


 The purple-haired girl, at the peak of beauty, gave another coquettish, high-pitched cry, part sob, part joy. Her body stiffened, reaching a second climax.


 As the hot, thick life energy surged inside the sacred and tender Flower Palace (Hanamiya), a third unexpected climax arrived.


 Unparalleled pleasure and stimulation descended upon her pure, voluptuous body. The long-legged girl shivered all over, once again losing consciousness under Aki.


 Setting down the unconscious Takamine Sayuri, Aki turned to embrace the mostly recovered Takamine mother.


 A new round of Dual Cultivation³ began.


 The Takamine Family’s affectionate life continued for a week, until all pre-New Year ingredients were used. Only then did Aki allow the mother-daughter trio to fully transform into his shape.


 After this week of diligent Cultivation, Takamine mother’s Mana reached B-rank, fully catching up with the Takamine Sisters.


 Such rapid progress made the Takamine Sisters envious. After Aki explained, they understood that their magic Talent was inherited from Takamine mother.


 Though still slightly reluctant, they could barely recall the face of that deadbeat father, so complaints were impossible.


 Of course, the biggest contributor to Takamine mother’s rapid improvement was Aki.


 With his S-Rank peak Mana and Dual Cultivation with Takamine mother, her cultivation speed increased more than tenfold.


 During this week, besides Dual Cultivation, Takamine mother recounted the past six months’ experiences and learned from Aki about Stray Devils, Fallen Angels, Angels, Heroes, and other Inner World knowledge, effectively becoming a member of the extraordinary world.


 Thus, Aki proposed having her replace Miyajima Sakura.


 Even after understanding how many women Aki had, Takamine mother, though prepared, could not help but be surprised and slightly upset—not for herself, but for her daughter.


 However, seeing her beloved handsome adopted son tenderly loved by Aki, that small dissatisfaction vanished.


 Tokyo’s winter vacation was very short. Due to the three-semester system, the New Year holiday plus winter vacation lasted about half a month.


 The real winter vacation was from January 1 to 10, ten days in total.


 On January 9, with two days left, Takamine mother finally agreed to Aki’s proposal.


 She decided to resign from her job, dedicating all her energy to managing the organization.


 Many factors influenced her: the shock of extraordinary powers, the ill intentions of her superior, and Aki’s parents, missing for many years.


 At night, after finishing the meal, Aki licked his lips and praised, “Big Sis Yuri’s cooking keeps getting better.”


 After reaching A-rank, his appetite had returned to normal. He could skip meals, but enjoying food remained a major pleasure, just like Rias and others keeping afternoon tea habits.


 To satisfy Aki, Takamine Sayuri devoted herself more to cooking research.


 Rather than making large quantities of filling food, she preferred this style, enjoying it and showing visible progress.


 Aki suspected that, if she continued, the skill of cooking might naturally develop in her.


 At this moment, Takamine Ayame rubbed her stomach, smiling in satisfaction. “Yeah… I feel a bit fatter. Sayuri’s cooking is too good, and I accidentally ate too much,” she said.


 ”Sayuri’s skills have completely surpassed mine…” Takamine mother nodded, sighing.


 The praised purple-haired girl smiled shyly, starting to clear the table, looking every bit like a virtuous wife and good mother.


 Anyone seeing this could not imagine that Takamine Sayuri, in bed, was essentially a nymphomaniac, and the most sensitive of the mother-daughter trio, fainting from pleasure at the slightest provocation.


 The Takamine Sisters washed dishes together. Takamine mother pulled Aki onto the sofa, sharing her decision.


 ”Aki, I agree, but it will be next month. The company requires a month’s notice,” she said.


 Aki guessed she would not refuse, having witnessed the extraordinary world and not needing money. Yet, receiving the reply made him happy, especially knowing she would resign.


 Though her experience prevented other men from taking advantage, men dislike seeing their women constantly exposed.


 Especially someone like Takamine mother, a beautiful single mother, long subjected to outside suitors.


 Aki wrapped his arms around her waist, smelling her faint fragrance. “Kasumi-neesan, just resign directly. It’s only one month’s salary. We’re not lacking that now,” he said.


 Takamine mother rolled her eyes, speaking irritably. “It’s not about the money. After working so long, I must properly say goodbye to colleagues, allow time to hire new people, and hand over my work.”


 ”Hehe, Kasumi-neesan really has professional integrity, even though you complained about your boss before.”


 ”That old man isn’t a good person, but the rest are fine, and the president treated me well,” she said.


 She sighed slowly. “Back then, the president wanted to foster his son with me. I refused, thinking I’d lose my job, but the other party didn’t hold a grudge and continued to take care of me.”


 Takamine mother became a single mother in her early twenties, inexperienced, balancing work and household.


 In Neon, women were generally disadvantaged at work. In her situation, most companies wouldn’t have chosen her.


 ”So Kasumi-neesan’s company president was that familiar person?” Aki asked, surprised.


 She nodded. “Yeah, that president was friends with Ayame’s father…”


 She sighed slightly, not continuing, and said, “I refused him not only because your parents gave more money, but also to avoid gossip. Unexpectedly, I ended up falling for you.”


 As she spoke, the now younger-looking widow lightly punched Aki. She recalled her actions that day as incredible.


 Influenced by Aki’s Charm Talent, Bitter Parent Template, and the Takamine Sisters’ help, Takamine mother, having suppressed herself for over ten years and now at peak desire, succumbing so quickly was normal.

Notes:


• Sayuri – Younger Takamine sister: long light‑purple ponytail, slender provocative figure in a tidy school uniform. Polite and submissive to her mother, she handles chores and cooks for Aki, showing masochistic devotion and urging her mother into an intimate circle. B‑Rank, she stays in touch with other girls Aki helped, stands obediently behind her mother in confrontations, and is part of the ‘Sister Flowers’ duo. In Dual Cultivation she trembles, is emotionally expressive, extremely sensitive, and faints from pleasure.

• Aki – Known as “Natural,” this S-Rank transcendent and Gremory secret weapon is the Takamine family’s adopted son. A tall, muscular youth with bat wings, a barbed tail, and crimson eyes, he masks his cold, predatory, and strategic “scumbag” nature behind a harmless student facade. He wields Dual Cultivation and Instant Illusion, mentoring Kasumi, Ayame, Mittelt, and Kalawarner through complex, intimate bonds.

• Takamine Sayuri – Aki’s reserved, non-blood-related younger sister with short brown hair and gentle eyes, always dressed in a neat school uniform; excels at chores and possesses a ‘Flexibility’ talent, displaying submissive, masochistic devotion centered entirely on Aki, with maternal instincts and an unwavering desire to remain by his side, appearing in Takamine-ke no Nirinka – The Animation.

• Takamine – Kasumi Takamine, a widowed matriarch, shares her surname with daughters Ayame and Sayuri — tall, curvaceous, voluptuous Transcendents who, under Aki’s guidance, have become corporate partners of the Gremory family. Aki, their adopted brother, now leads an organization, reshaping the household into a liberal, emotionally charged sanctuary where magic and intimacy intertwine.

• Y – The first initial/part of the name Y Ddraig Goch.

• Takamine Sisters – Two sisters living with Aki who have recently begun Mana extraction.

• Miyajima Sakura – Upperclassman Miyajima Sakura, a striking kendo prodigy with “Sword Heart,” studies at Aisu Academy and now at Aie Academy. Living with Aki—whom she views as a younger brother despite his predatory nature—she is brave, romantically sensitive, a former Kuoh student, a club beauty targeted by Tanaka Hajime, and unaware of the supernatural.

• Miyajima – Family name of Sosuke, Tsubaki and Sakura.

• Sakura – Miyajima Sakura, a third-year Aisu Academy student and kendo prodigy with the Sword Heart talent, wears a navy blazer and red hakama; daughter of Sousuke, she surpassed him in strength and now lives with Aki, whom she treats as a younger brother despite his predatory nature. She manages his organization and practices Dual Cultivation with him, though he considers replacing her with the more socially adept Kasumi due to her superior talent and experience.

• Rias – Rias Gremory, 17, tall curvaceous pure‑blood devil with long crimson hair, crystal‑like crimson eyes, snow‑white skin and jade‑smooth back; her stray‑devil wings flare when summoned. As Kuoh Town administrator and Occult Research Club president, she mentors Aki like a big‑sister professor, leads his peerage, wields the Power of Destruction as Crimson Ruin Princess, and commands reincarnation via Evil Pieces.

• Takamine Ayame – Eldest Takamine sister, tall and confident with long pink hair, slender waist, large breasts and an athletic build. Bold, open‑minded, a flexible swimmer and Aki’s host‑family older sister in Garden: Takamine‑ke no Nirinka. Playful yet resistant to her sister Sayuri, ultimately submissive. One of Aki’s non‑blood sisters, energetic, curvaceous and eager to learn magic.

• Ayame – The eldest Takamine sister is a tall, athletic, pink-haired fire mage and popular swimmer at Aisu Academy. Playful and extroverted, she balances a mischievous, teasing nature toward her sister Sayuri with submissive devotion to Aki, whom she calls “Master.” Though she can be quiet and observant, she openly encourages Aki’s advances toward her mother. A B-Rank fighter, she is empathetic toward Aki’s allies.

• Kasumi – Kasumi Takamine, a tall early-forties widow with snow-white porcelain skin, light-brown wavy hair twisted back, and a voluptuous, curvaceous figure, is the resilient matriarch of the Takamine household and mother to Ayame and Little Yuri. A mid-level manager turned entrepreneur, she often wears an office lady uniform and possesses B-rank magical strength. Once employed by a company president, she resigned to found her own business while balancing domestic duties and cultivation training. Shy and reserved, she conceals deep guilt and forbidden desire for Aki—her long-time guardian and the man whose presence awakens her Mana Affinity—protecting him fiercely even as intimate encounters unfold under her daughters’ silent watch.
