I Took A Succubus's First Time-Chapter 122: The Love Link Container

Humans and demons had entirely different biology. Unlike humans, demons—and even angels—had natural parts in their bodies that let them manipulate mana freely. Humans, on the other hand, could only generate aura, and even then, only a handful of people were capable of doing so. Humans couldn't use mana at all, forcing them to rely on specialized weapons and equipment like the Holy Weapons to even harness its power.

With that in mind, a human and a demon conceiving a child simply through multiple rounds of sex wasn't something that happened easily. It was possible, sure, but not common. However, the existence of half-human, half-demon offspring had long been a reality. In fact, there were quite a few of them in the world now—one of the members of the Sarushima group was proof of that.

So while the chances were slim, there was still a possibility that Yuuna could become pregnant in the future. That was why she had asked if she would make a good mother.

Yuuna, personally, wasn't sure she would. Her mother certainly didn't fail in raising her, but whether she had been a good mother was another question entirely. Sure, she had nurtured her, but only through the vision she had for Yuuna, shaping her into the cold, emotionless woman she had become. A woman who could smile but felt little else. If Yuuna were to have a child, would she do the same? Would she mold them into something she wanted rather than letting them grow into who they wanted to be? That thought unsettled her.

"I think you're going to be a good mother, Yuuna-san," Kouhei said.

Yuuna blinked, caught off guard. "Really? I kind of doubt that. I mean, just judging from my personality alone, I don't exactly scream 'mother material.'"

"You think so? But, Yuuna-san, don't you think leading the Yuuna Faction already proves you'd be a great mother? I mean, you've taken care of them, right? You've been someone they can rely on. If that's not motherly, then I don't know what is."

From the moment Kouhei had arrived in this place, he had seen firsthand how much Yuuna cared for her faction. If he didn't know any better, he might have thought she really was their mother. She was far more motherly than she gave herself credit for. So if the time ever came where Yuuna got pregnant, Kouhei had no doubt she'd be an amazing mother.

"That's sweet of you to say," she murmured, a small smile tugging at her lips. "If you say so, then when the time comes, I'll be the mother of all your children, Kouhei-kun."

She snuggled closer, pressing her head against his chest, listening to the steady rhythm of his heartbeat.

At some point, exhaustion finally caught up to her, and she drifted off to sleep. It wasn't surprising—she had been tired. Kouhei watched her for a moment before leaning in to press a soft kiss to her forehead. Then, with the warmth of her body nestled against his, he allowed sleep to take him too.

After that day, all the members of Yuuna's faction returned to their usual lives. Technically, they were in a faction war with Souichiro's group, but that didn't mean they had to abandon their daily routines. Yuuna had made it clear—war didn't erase the fact that they still had lives to live.

Misuzu continued with her modeling gigs after school, while the first-years returned home to handle their responsibilities as heads of their respective houses. Yumi did the same. Almost everyone in Yuuna's faction resumed their daily routines.

But that didn't mean they were turning a blind eye to the war. They weren't foolish enough to think peace would last. Every movement, every routine—everything—was carried out with a heightened sense of awareness. Even though they appeared relaxed, they were watching, waiting, calculating. No one was wasting time. No one had given up.

At this moment, Yuuna, Hina, Nagisa, and Kouhei stood before the entrance of the Matsui household, a place that had its own peculiar presence. The moment they stepped inside, the air changed—a faint scent of metal and burnt oil mixed with the musty warmth of aged wood and machinery. It wasn't the smell of rot or decay but of something alive, a place where creation and destruction went hand in hand.

Matsui Shizue stood in the middle of the cluttered room, her small frame barely visible amidst scattered tools, blueprints, and half-finished contraptions. She looked like a girl lost in time—short, delicate, but carrying an aura that made it impossible to underestimate her. A massive, crudely welded metal hat sat atop her head, almost as if it had been thrown together from discarded scraps. The size made it slip slightly over her forehead, barely held in place by a pair of tinted goggles. Strands of her hair, matted with grease and dust, stuck to her temples. There were dark streaks of oil smeared across her cheekbones, and her leather apron bore deep burn marks and tiny tears, proof of countless hours spent in labor.

The Matsui house was small—just three members. It had been established seven years ago, a relatively new addition, considering the long histories of other noble demon families.

There were no historical records of a Matsui house among the demons because Shizue had chosen to take her mother's maiden name, a human name, instead of using her father's demon surname.

She was half-human, half-demon. Her mother was human, and her father was a demon.

"Welcome to the Matsui House, President," Shizue greeted, her voice steady but her posture slack, as if exhaustion had sunk into her very bones. Her bow was slow, almost lazy, like the weight of her own body was too much trouble to carry. "And to the rest of you as well."

From behind her, two more figures emerged—a boy and a girl. Their outfits mirrored Shizue's, minus the oversized hunk of metal she called a hat, but their bodies were just as smeared with oil and soot. The faint hum of machinery still clung to them, as if they had only just stepped away from their work to acknowledge the new arrivals.

"It looks like you were in the middle of something. Are we interrupting?" Yuuna asked, her sharp eyes scanning the surroundings, taking in every detail.

"It's fine," Shizue replied with a shrug. "Actually, your timing's perfect. I just finished what I was working on."

"Already?" Yuuna's brows lifted slightly. "That was fast. I thought it'd take months, but you're telling me you've finished in less than one? That's impressive."

Shizue smirked, tapping a finger against her temple, leaving behind a faint streak of oil. "You forget, President," she said, her voice light with amusement. "I'm Shizue. I can make whatever you need in a flash."

Her grin widened, eyes gleaming with a confidence that came from knowing exactly how capable she was. Yuuna met her gaze, and for a brief moment, Kouhei caught something in her expression—pride.

"Alright then, let's see it," Yuuna said, her voice carrying an unmistakable excitement.

Ever since Souichiro declared a faction war against her, she had given Shizue a special task—something that would turn the tide in their favor. Something that would change the game.

"I'll lead the way," Shizue said, turning on her heel as she guided them toward what appeared to be a basement.

The stairs stretched downward far longer than expected. For a house as small as the Matsui household—especially when compared to the grand Saonji Mansion—this descent felt almost surreal. It made sense, though; only three people lived here, so the house itself wasn't anything extravagant.

But when they finally reached the bottom, Kouhei froze in place, his breath catching in his throat.

This wasn't a basement.

The walls gleamed in pristine white, reflecting the cold, sterile glow of overhead lights. The space stretched so far and wide that he had to blink—several times—to make sure his eyes weren't messing with him. But no matter how many times he tried to readjust his vision, the truth remained the same.

This place was massive.

It looked less like an underground room and more like a secret hangar—the kind straight out of some sci-fi movie or a superhero's hidden base.

Scattered across the space were all kinds of futuristic-looking devices, half-assembled machines, and mechanical contraptions that didn't belong in this world. Some things looked like weapons, some like vehicles, and some were just… unidentifiable. Among them, a particular piece caught his attention—a giant gun, its barrel gleaming under the artificial light.

"Surprised, Kouhei?" Hina teased, standing beside him with an amused smirk.

"I-I mean, yeah. Surprised is understating it," Kouhei stammered, his mind struggling to process what he was looking at. "I don't think I could've ever imagined seeing something like this in my entire life. If I had never come here, I probably would've gone my whole existence blind to things like these. Like, does a normal human even begin to process this?"

"Fufufu… Shizue's been up to a lot of things," Nagisa chimed in, her voice carrying a hint of mischief. "Some of the stuff here is actually insane. You should try riding that, Kou-kun."

She pointed toward something that resembled a sleek, futuristic motorbike—except it didn't just look like a motorbike. The design was sharp, almost predatory, with faint glowing lines running along its frame.

Kouhei swallowed hard. "That looks… dangerous for me."

As they walked deeper, taking in the sheer absurdity of the underground facility, Shizue finally came to a stop.

Before them stood an object, completely hidden beneath a massive cloth.

She turned to them, eyes glinting with excitement.

"Behold," Shizue declared, gripping the cloth in her hands before yanking it off in one swift motion.

"The Love Link Container!"
