Ryuji really wanted to complain.
Even if Rias didn't count as human, what about Rin Tohsaka, Mai Shiranui, and that tanned woman?
What—women don't qualify as human now?
He didn't remember NieR: Automata having any kind of gender-based discrimination.
And seriously, for artificial beings like her, did gender even matter?
But the real kicker was…
He wasn't even from the NieR world!
Sure, he only knew 2B from her 3D waifu fame, but he still remembered the basics of the lore.
Humans from that world weren't ordinary people—they had souls capable of adapting to "magic particles" or magic elements.
And he—just a regular guy from Earth—had no such compatibility, or at least, shouldn't.
There was no way his body could naturally handle the energy or magic from that world.
Ryuji chuckled lightly at the absurdity—but that question triggered a memory he had been conveniently ignoring until now.
How was he able to use magic from the Arad world in the first place?
Sure, magic there was a combination of mental and physical power, where mana was often seen as an extension of one's life force.
But he was Earth-born. No way his life force matched an Arad native.
And most importantly…
Did Earthlings even have the same kind of soul?
Testing the waters, he asked, "Uhh, aren't the others technically human too?"
2B shook her head firmly, her face remaining perfectly stoic and serious.
"They are not human. You, noble human, are the only one. The others are humanoid in appearance but biologically and spiritually different from our documented human. My ocular scans alone confirm their difference. And after analyzing your bodily fluids, the presence of compatible magic particles proves it—you are, without doubt, human."
Ryuji blinked.
What…?
He frowned. His instincts screamed that something was off here—deeply off—but when he opened his system interface, there was no explanation to be found.
A hidden benefit? A bug in the system? Pure coincidence?
Ryuji decided it was time to ask some actual experts.
Mai probably wouldn't know—she was a martial artist. But Rin and Rias? They might be able to detect something on a magical or spiritual level.
Still, he kept things polite and simple.
"Well, Miss 2B, I'm pretty sure I'm not from your world. There might be a misunderstanding here."
Even if her believing he was human gave him god-tier privileges—basically turning her into an obedient, loyal waifu who'd do anything for him—Ryuji didn't find that kind of manipulation fun. Too easy. Too hollow.
2B's brow twitched slightly, though Ryuji didn't catch it.
She was growing worried. What if this noble human was being manipulated—seduced—by those three pseudo-human females?
Humans often pursued beauty… and mating. And those three had desirable appearances by human standards.
She stood upright and saluted sharply.
"Please do not deny your humanity, noble one. If you are being threatened or deceived by those three female-type humanoids, I can neutralize them and protect you until YoRHa forces arrive. And if your needs involve beauty or reproduction—although I am merely artificial and far inferior to a true human—I offer myself freely for your use."
She was dead serious.
Androids like her revered humanity as divine. Serving humans was their core directive, their purpose. If Ryuji asked her to sleep with him, she would not hesitate. She would comply, assist, and even store his sperm material inside her. Upon returning to YoRHa, she would deliver it directly into the human gene archive.
Sworn by her core code, she would not waste a single drop.
That functionality? It absolutely existed.
In fact, their design prioritized realism to such a degree that they could even bear fertilized embryos and give birth.
But such a privilege—to carry a human's child—was considered the highest honor. Only androids who had performed heroic deeds or received divine favor from a human could ever qualify.
No one had ever earned it. Most androids never even dared dream of it.
Many would consider it a lifelong wish fulfilled just to see a human once—much less be chosen by one.
"Uhh…"
Ryuji couldn't help but glance at her thigh-high black boots, the glossy stockings, and that black dress with its peek of flawless skin between.
Say what you will about YoRHa—they had excellent taste when it came to sexy uniforms.
Even the male androids, like 9S, had that whole priest-meets-pretty-boy look going on.
Her legs were the perfect thickness. Her chest was full but not oversized. And that blindfold—God—that blindfold added a whole new layer of temptation.
He felt… urges.
But he restrained himself.
"I think you should double-check whether I'm really human. Like… with a genetic test or something. There could be a mistake, right?"
Ryuji had standards. If 2B wanted to have sex to return to her world, sure—he'd be more than happy to help.
But if it was based on a lie? That was too low.
It was a brush-off line, but 2B nodded earnestly.
"Understood! If that is the wish of a human, I shall obey. However, in the absence of external equipment, I can only perform genetic verification using my internal systems. Would you like to proceed with the genetic compatibility check now?"
"Huh?"
You can do that?
Ryuji blinked in surprise but nodded. He needed her to drop this topic.
"Yeah, go ahead. Might as well. I'm definitely not from your universe, though."
Like hell NieR: Automata would exist inside the NieR universe itself…
He grumbled internally.
"Understood! Shall we perform the test here?"
"Huh? Uh, sure. Here's fine."
"Understood. Glory to mankind. Forgive my offense—I shall safeguard your genetic information with utmost care."
Then she did it.
She slammed a fist lightly against her chest and gave him a firm nod. And as Ryuji stared, dumbfounded, she began to undress.
She undid the buttons of her black dress, revealing a deep-V, backless bodysuit underneath.
Her movements weren't shy or embarrassed—they were calm. Like this was completely normal.
And in the NieR world… it was.
Androids serving humanity in such ways was written into their foundational code.
As she bent down, preparing to slip out of the bodysuit with a sultry but oddly clinical pose, Ryuji quickly stopped her.
"Whoa whoa—wait. Hang on. What exactly do you mean by 'genetic compatibility check'?"
Only now did it click—something about this seemed... off.
2B replied without hesitation:
"I will use my internal sperm preservation unit for verification. It has a specialized filter system. If your genetic material can successfully enter the storage chamber, you are, without doubt, a true human. That would conclusively confirm your identity."
"Wait—what!? where this device is located!?"
"Around my lower abdomen," 2B answered Ryuji's question with complete seriousness, her tone unwavering.
"But there are also transmission devices in my oral cavity and the simulated passageway that can transfer samples into a preservation unit."
"…"
Ryuji covered his face, completely speechless.
These people from the NieR world... What the actual hell are they thinking?
Sure, he could tell they were "advanced," but this level of detail? It was just too much, even for him.
Why the hell would a combat model like 2B be equipped with stuff like that?
Couldn't they just design these androids to not look like humans at all?!
He wanted to rant, loudly and thoroughly, but then a detail about 2B's backstory came to mind—Android bodies were originally designed to help humanity survive. While the YoRHa units like 2B were a bit different, the design philosophy was still the same at the core.
Just as he was about to stop 2B from continuing what she considered a completely normal procedure, three figures descended from the cliff above.
And when the lead girl—Rin Tohsaka—saw Ryuji and the partially undressed 2B, she gave him a look and said, with a sigh of disbelief:
"Hey. What the hell are you doing? Or wait, are you that so-called 'real human' she kept talking about?"
Rin was clearly fed up.
After hearing Rias's explanation, 2B had suddenly snapped, declaring none of them were human, and then leapt straight down the cliff like a lunatic, scanning everything in sight.
Especially Rin—she was personally offended at having her "human status revoked" for no apparent reason.
"Uh… 2B said I was a human from her world and wanted to verify my genetic data. That's why things look a little awkward right now," Ryuji explained. "But I'm certain I'm not from her world. Rias, Miss Rin, could I ask you both to help me with an experiment?"
"Hm?" Rin raised an eyebrow, confused.
Rias looked puzzled too. "What kind of experiment?"
Ryuji's expression turned serious.
This wasn't just idle curiosity—it had everything to do with his powers and his future plans.
"I want to test whether I qualify as a human in your worlds," he said. "And whether you qualify as humans in each other's worlds."
"…Huh?"
Rin clearly didn't get it.
But Rias, watching 2B—the rare technological creation with a sense of self—seemed to catch on. She nodded.
"Of course. We'll help."
——————————————
"Unbelievable!"
Rin stared down at the blood sample before her, then back up at Ryuji with wide eyes.
"You really are human! I mean—not just any human, but my world's human?! And you can draw out mana without magic circuits?!"
She grabbed her twintails in frustration, like her brain was about to explode.
With Rias's help, Ryuji had his blood tested against four different people. And the results were...
In every case—Rias's world, Rin's world, the dark-skinned girl wearing a cowboy hat named Kiki, and even Mai Shiranui—Ryuji was confirmed as an authentic human being native to their respective worlds.
But when they tested each other?None of them registered as humans in each other's worlds.
Their results varied entirely. It was clear—they weren't the same species.
Hell, you could even argue they weren't the same type of being.
Their body structures were similar, sure. But it was like comparing smartphones from different brands—same general shape, same functions, same charger—but fundamentally, different devices.
Even their magic systems didn't cross over.
Rin couldn't use Rias's magic at all, and vice versa. What looked like powerful spells in one girl's hands turned into childish nonsense in the other's.
But Ryuji? He could use both.
Sure, his magical aptitude was terrible, but he could still activate their spells—with full effect, no delay, no degradation.
But that wasn't the part that really shattered Rin's brain.
If Ryuji truly was a human from her world… then how the hell was he generating mana without magic circuits?
In her world, mages required those circuits to cast or even gather mana. No circuits, no spells.
So if he didn't have any… then the only explanation was—
He was at least a human from the Age of Gods—or worse, a phantasmic species.
Is this some kind of joke?!
If he really was a god-age human or a phantasmal being, there was no way his blood would test as "ordinary human."
Rin was spiraling.
"It seems Ryuji is quite… extraordinary," Rias said with a growing smile, her fingers thoughtfully touching her chin as her gaze lingered on him.
The longer she looked, the more intrigued she became.
It was the instinct of a devil—to hunt, to collect rare treasures. And Ryuji was the rarest of them all.
If he agreed to become her servant, and showed the potential to become a Maou-level being, she wouldn't hesitate to reward him—with even her own body, if necessary.
"Don't give me that suggestive look," Ryuji muttered, arms forming an "X" in front of him. "Yeah, you're gorgeous, but becoming your servant? Not happening."
Then he turned to 2B—who had remained silent, standing vigil behind him ever since the tests.
"Now do you understand, Miss 2B? I'm not a human from your world. I'm just… very unique.
"So if you're not planning to leave, there's no need for those 'weird procedures' anymore. And even if you do leave—just use your mouth, that's enough."
But...
2B stared at Ryuji as he tried his best to explain things to her. From her perspective, it seemed clear—humans were easily swayed.
She didn't quite understand the magical techniques those two women used, or why they would lead Ryuji to develop trust in them. But the conclusion she'd reached was undeniable:
Ryuji was a human.Their human.
No matter how many scans she ran, no matter the saliva samples she'd analyzed during that kiss—it all pointed to the same result.
Without a doubt, human.
Still, as she looked at the serious expression on Ryuji's face, she paused. She didn't voice her disagreement out loud. Humans needed her confirmation—so she gave it.
But in her mind, nothing had changed. Ryuji was human.
"Understood," she said calmly.
"That's a relief," Ryuji exhaled, visibly relaxing.
"However," 2B continued, "if what you say is true, then I must return to the YoRHa command as soon as possible. I don't know if your claims are accurate, but I must attempt to confirm them."
She placed a hand over her chest, her voice steady. If Ryuji refused to acknowledge that he was one of their humans, then she had no choice but to proceed with a full genetic verification.
This wasn't just about her personal orders or trust. It was protocol. She had to confirm whether Ryuji was a true human—and protect him accordingly.
Rin's lips twitched in disbelief. "This is getting out of hand..."
She sighed.
"Well, it's good news for us, I guess. I mean, we still don't know how he's planning to send us back, but 2B, I'm telling you—he really isn't from your world."
Under normal circumstances, 2B would've already eliminated any suspicious, non-human females possibly influencing her subject. But Ryuji was too vulnerable in this world, too fragile. So she held back. Instead, she explained the urgency behind her decision.
"I'm a unit of the YoRHa squad. When I arrived here, I was in the middle of a mission. If I fail to report back in time, I'll be flagged as a deserter. I must resume my operation as soon as possible.
As androids, we don't possess emotions or shame. Actions like these have no intrinsic meaning to us. Any damage incurred can be repaired with replacement parts. So, there is no problem."
Her voice remained detached and clinical. Rin scratched her cheek awkwardly, realizing again that she was talking to a machine.
One that looked… almost indistinguishably human.
"Right… I guess that makes sense."
She turned her face away, unsure of how to respond.
Meanwhile, 2B turned and bowed deeply to Ryuji. Her voice was solemn, polite, and disturbingly straightforward.
"Please make use of my body. While not quite the same as a real human body, I can replicate the experience to a high degree of accuracy, and I hold a certified purity rating. I don't have high-tier programs specifically tailored for human pleasure, but every android comes pre-installed with modules that can enhance the sexual experience."
She meant every word.
Ryuji, now acutely aware of the other women watching this exchange, let out a mortified cough.
"Honestly, just using your mouth would've been enough…" he muttered.
But 2B shook her head with mechanical precision.
"I am pursuing maximum stability. Please use the primary passage. It's closer to the sampling unit and ensures more accurate data preservation."
Ryuji stared at her in stunned silence.
This whole situation… was getting way too surreal.
