Crossover-Isekai 320

Chapter 320 Another Mission


Edited by: Kanaa-senpai


 Sometimes, a trip to the restroom isn’t really about needing the restroom.


 Aki chuckled, leaving the explanation hanging.


 To keep certain girls in his class happy, he visited not just the restrooms, but also the school rooftop and the infirmary.


 However, ever since Chisato Hasegawa took over as the school doctor, Aki rarely went to the infirmary.


 It wasn’t that he was worried about being seen; he just didn’t want to accidentally provoke her.


 Chisato Hasegawa had shown up at Kuoh Academy long before Basara Toujou, and it was very clear her goals were entirely different from the ones he remembered.


 Before he could be certain of her goals, Aki preferred to keep his distance unless he reached God-tier strength.


 A Super-Devil might seem powerful, but they were nearly helpless against a God-tier fighter.


 While a Super-Devil and a Demon King occupied the same general realm, the former possessed a strength that was far superior to the Demon King-class.


 A God-tier being, meanwhile, could cut a Demon King-class’s full-power attack in two with a single strike, splitting the seas, carving away beaches, and wiping out mountain ranges in the process.


 The mere ripples of their released energy could break mountains.


 Without holding back, they could destroy the world through pure violence.


 As for the even stronger Sub-Dragon God-level entities, the aftershocks of their battles were enough to destroy the world completely.


 Because of this, those living within the Three Realms (the realms of humans, Devils, and Gods) reached a ceiling at the God-tier; by controlling their output, they could still fight.


 Sub-Dragon God-level entities and those beyond lived in the endless, void-like universe outside the Three Realms, whether sleeping, training, exploring, or at war.


 Yuzuki Nonaka wasn’t a naive, sheltered girl, but she wasn’t quite at the level where she could instantly grasp the nuances of Aki’s intent.


 She tilted her little head, her wide eyes filled with confusion—unexpectedly cute.


 Although she didn’t fully understand, the Hero Schoolgirl said, “Whatever you’re doing, I’m coming with you.”


 ”Fine. Tag along if you must, just don’t say anything extra,” Aki replied dismissively.


 Aki didn’t mind being watched by a Schoolgirl, but he wasn’t sure he could hold his tongue if someone kept insulting him.


 If this had been Kurumi Nonaka, it would have likely caused a scene, but fortunately, the one assigned to close-surveillance duty was Yuzuki Nonaka—a cold beauty of few words.


 Perhaps it was exactly because Kurumi Nonaka lacked that calm temper that Yuzuki was tasked with watching Aki.


 And so, on the first day of the second semester, a cold Schoolgirl tag-along appeared behind Aki.


 Whether he was eating, sleeping, bathing, or in Dual Cultivation (a practice of sharing magical energy through intimacy), Yuzuki Nonaka was always by his side.


 At the very beginning, Yuzuki had been shy, turning her head away during certain scenes.


 But at some point, the cold Hero Schoolgirl stopped being shy and even began to ask Aki about it, especially concerning the mechanics of Dual Cultivation.


 In the sports warehouse, Reina Hamazaki braced herself against the wall, her back arched and hips thrusting, muffled groans escaping her lips.


 Behind her, Aki gripped her soft waist, his thick, Great Dragon buried deep within her moist, soft Flower Valley, every thrust drawing out splashes of clear fluid.


 ”Ugh… Aki… faster… faster… I’m about to…” Reina panted, her voice shaking.


 ”This one’s for you; that’s your share for the week,” Aki grunted, thrusting with renewed force.


 The sensitive head of his member pressed past layers of soft, yielding flesh, sending waves of pleasure racing up his spine to his brain.


 After dozens of thrusts, the large head pushed past the soft opening of the Flower Palace (Hanamiya), creating a clear bulge against Reina Hamazaki’s flat, snow-white lower stomach.


 Looking closer, it wasn’t just the head; the girl’s entire lower stomach was stretched by the width of the Great Dragon into a cylindrical shape.


 Aki freely ground the head of his member against the soft flesh of the walls, pushing for the final stretch.


 At this moment, Yuzuki Nonaka, who had been standing silently to the side, asked with real curiosity: “You sleep with several different girls during the day at School, and then go home to do it with Rias-senpai and the others at night. Can your body handle all of this?”


 Aki was at a critical point and didn’t want to answer.


 But, looking at her pair of sexy, long, smooth legs beneath her athletic shorts, his heart skipped a beat.


 ”Yuzuki… um… come a little closer…”


 Hearing Aki’s heavy, labored breathing, Yuzuki Nonaka understood he was about to climax; she had picked up on some of his habits through observation over the past few days.


 The sky-blue-haired Hero Schoolgirl hesitated for a moment before finally stepping forward.


 Her ivory legs were within reach. Aki quickly let go of Reina Hamazaki’s waist and wrapped his arms around Yuzuki Nonaka’s alluring form.


 Yuzuki’s body trembled, her fair face flushing bright red. Her smooth, rounded legs clamped together without thinking, and a trickle of clear fluid seeped from the gap in her athletic shorts, trailing down her soft inner thighs.


 Aki didn’t push his luck; he just held her like that, his body shuddering as his Great Dragon flooded the depths of Reina Hamazaki’s Flower Palace (Hanamiya).


 ”Ugh… so hot… so much…” Reina cried out.


 Reina Hamazaki’s eyes rolled back, her legs tensed sharply, and her Flower Valley rhythmically spasmed, milking the remnants of Life Essence from Little Aki (Aki’s member).


 After the pleasure faded, her sexy, soft body slowly slid down the wall, and the still-hard Great Dragon slowly withdrew from her body, bringing out a large amount of thick Essence.


 Reina Hamazaki lay on the mat, gasping for air.


 Around her, Yukina Sasaki, Ruri Kurumizaka, and Yuki Shinomura lay in a similar state of dreamy exhaustion.


 Aki looked at the worn-out Gyaru quartet (a group of trendy girls), then turned his gaze toward the flushed Yuzuki Nonaka in his arms.


 ”Yuzuki, whether my body can handle it or not… you can experience it for yourself,” Aki whispered.


 The hot Great Dragon, carrying the scent of musk and sweetness, pressed against Yuzuki Nonaka’s smooth, fair legs. The burning, slick sensation made the Hero Schoolgirl’s heart race.


 Her already aroused Flower Valley began secreting a warm nectar once more.


 Seeing Aki throw parties every single day, anyone would find it difficult to resist, as long as their body could handle it.


 Especially since she had witnessed the girls moaning under Aki, reaching pure bliss—it only fueled her curiosity.


 Her Flower Valley felt empty and itching. Yuzuki Nonaka’s face was bright red, and the Great Dragon forced its way between her tightly clamped legs.


 Through her athletic shorts, Aki began to play.


 Every bit of friction brought the Hero Schoolgirl—who had never even tried touching herself—a jolt of electric pleasure, but she still didn’t voice her consent.


 ”Yuzuki, since you want to find out the secret to Dual Cultivation, why don’t you try Dual Cultivating with me yourself?”


 The girl’s body trembled out of control. While enjoying the sensation of her smooth, supple legs, Aki added, “I imagine your personal experience would be far more convincing than my words.”


 Enduring the cravings of her own body and the unfamiliar pleasure, Yuzuki Nonaka stammered, “When… when did… you… notice…”


 ”From the first time you started asking me questions,” Aki replied.


 Aki had only been suspicious at first, but after living together for a few days—especially after Yuzuki had suddenly become proactive—he was certain.


 The Hero Clan had investigated him; it was impossible for them to have missed the Dual Cultivation Ability.


 Just like when he was first noticed by the Underworld Devils, every Peerage (a Devil’s group of servants) of Devils had wanted a piece of his Dual Cultivation Ability, constantly sending girls his way.


 He had rejected everyone except Ravel.


 Later, the Gremory household, the Phoenix clan, and the Sitri family had spoken up at the same time, and the Devils’ Peerages had ceased their efforts.


 Clearly, the Hero Clan had been harboring similar ideas.


 There was no shortage of women among the Heroes, and if Aki’s Dual Cultivation Ability were as powerful as the rumors suggested, they might even try to steal him away.


 From the perspective of the Hero Clan, Aki had been human originally, so he should naturally have an liking for them.


 Coupled with the fact that the Toujou father and son were on good terms with Aki, the idea seemed even more solid.


 And so, beyond their surveillance mission, Kurumi and Yuzuki Nonaka had been tasked with measuring the extent of Aki’s Dual Cultivation Ability.


 The mission had explicitly stated they were expected to make sacrifices to bring back the most accurate information.


 The Nonaka sisters were innocent, but they weren’t stupid; the elders’ intentions were clear enough.


 In the end, Yuzuki Nonaka decided she would be the one to carry out the task.


 First, to protect her younger sister, Kurumi.


 Second, because she feared Kurumi might fail the mission and end up losing more than she gained.


 Before they had even met Aki, they had been highly resistant to this mission.


 The sisters had even staged a tearful drama before leaving over who would be the one to make the sacrifice.

 Summary:

 Aki continues his complex web of relationships and power accumulation while under the surveillance of the Hero Clan’s Nonaka sisters. Yuzuki Nonaka, initially assigned to watch him, finds herself drawn into his practices after he exposes the Hero Clan’s true intent behind their monitoring. The scene ends with Yuzuki’s internal resistance crumbling as she confronts the reality of her mission’s requirements.

Notes:


• Aki – A tall, handsome Kuoh Academy strategist and King-status devil with a powerful, dragon-like physique and scumbag-like charisma, he wields Dual Cultivation and soul contracts to heal, empower, and psychologically condition his growing harem of schoolgirl knights and supernatural companions.

Her hidden divinity and arrival lead Aki to suspect the onset of specific plot events as he uncovers the truth behind her human facade.

• Basara – A handsome, spiky-haired Kuoh Academy student and magic novice, this pragmatic tactical thinker survived the Hero Village incident. Wielder of the holy sword Brynhildr and the Banishing Shift, Jin Toujou’s son and Aki’s ally is alienated by the Hero Clan. Driven to rescue his mother from the God-faction, he hosts his allies’ planning base to investigate enemies of the Gremory household.

• Toujou – Toujou is the family name carried by Basara and his father, Jin, connecting them to the Hero Clan and an ongoing conflict. Associated with Basara—a powerful individual whose existence is known to Aki—the surname is recognized for representing high combat potential and formidable strength.

• Reina Hamazaki – Reina Hamazaki, red‑haired with emerald eyes, is a top‑20 student at Kuoh Academy. Known for her proximity to Aki and awareness of his status, she leads a four‑girl squad as their Big Sister/Boss.

• Sasaki – Yukina Sasaki carries her family name as a statuesque Kuoh Academy freshman with peach-pink hair, purple eyes, a large chest, and fair legs in white ankle socks. A warrior-class prodigy with highest Mana and rapid recovery, she uses Physical Activation to boost her long-term partner Aki’s strength. Strongest of Reina’s trio, she feeds intel on Yuki and urges honesty in Hamazaki’s group.

• Yukina – A battle-hungry member of the Gyaru quartet, she shares a close bond with Aki and is always eager for combat, famously rolling up her sleeves in anticipation. She channels pale pink mana that flares into a brilliant blood-red hue when she pushes her physical reinforcement to its absolute limits.
