AN: So yeah, got this thing in my head, I just had to get it out here. After playing Nier Automata, and Utawarerumono, my imagination was literally going wild on what could have happened if this happened, and after polishing my thoughts a little, this happened.

So I present to you, this crossover between NieR Automata and Utawarerumono (Mask of Truth). Note that this fanfiction is mostly Utawarerumono centered, so please don't expect the lore to be up to spec with Nier's.

"Nekone!" Haku pushed the young girl away from Vurai's attack.

"Haku!" Oshutoru cried out as the attack vaporized Haku's form, save his tessen. "Vurai, YOU!"

"Now the insects are silenced." Vurai, in his akuruka form, bellows to the sky as he turns around to meet Oshutoru. "We can finally fight!"

Oshutoru, with the moments of his best friend dying to save his little sister flashing in his eyes, draws power from his Akuruka Mask.

With Oshutoru's emotions mingling with the Akuruka's functions, he was able to surprise Vurai with newfound strength, and with it, push Vurai to fall off a cliff to his supposed demise.

-Project YoRHa stage 3 initializing-

-Welcome Engineer Mashiro !DATA CORRUPTED-

-Congratulations. Due to absence of other personnel, you have been promoted to Director-

-Please report to the Human Resources Office to adjust your payroll and other benefits-

-cough-cough-

'Where am I? I am Haku? No, I am Mashiro, but I—' Haku/Mashiro sits up from a bed and then groans in pain as a flood of memories rushes in his mind.

"Director Mashiro! Please relax. Breathe in. Breathe out." Haku feels a warm hand on his forehead. "Temperature is 38 degrees, normal for current body parameters, current situation must be brain cells activating from cryogenic stasis."

"Forgive me doc, I know I'm a slouch, but saying my brain's been in… Wait, what did you say?"

"Director Mashiro, I am Medic 1-M, android assigned to watch over human-android bodies on activation."

'Impossible! It actually worked Our very farfectched plan to implant our heads with some nano technology to upload our brain's content to some server in space actually worked.'

Haku then examined his surroundings and took a deep breath as he looked towards the android.

"So, I'm the director?"

"Yes, other personnel have been deemed to be deceased on the outbreak of the Tatari phenomenon." 1M then produces a list of Project YoRHa's human team members. "As the remaining human of Project YoRHa, you have been designated as the director."

'So everyone's dead, just like you big bro...'

Haku scanned the list of his team.

'To think our crazy plan to extend our lives worked. The ability to send a full copy of our brains to an artificial one is possible after all.'

"Would the director like to change their current facial or body structure?" The android asked upon noticing her director's pensive look.

'Now that I look closely, the androids we created are damn fine, hiring those models to visit our headquarters for artistic and more human inputs was genius. Henry, Takahashi, Johnson, and the rest of the project team, I'll fulfill our dreams for us!'

"Director Mashiro?"

"Ah!" Haku/Mashiro, shook his head in surprise. "No thank you, I have taken a very permanent liking to my original face and body structure."

"Understood Director Mashiro"

'Kinda weird to be called director by a very beautiful onee-san, but I must endure. Everyone! I will endure!'

"Everyone…"

Flashes of memories suddenly rush to Haku/Mashiro, as he collapses from a sudden dizzy spell.

"Everyone… I must…"

"Director!" 1M screams in panic as her mechanical reflexes kicked in and caught the unconscious human. "Director, please rest."

-yaawn-

Haku/Mashiro opens his eyes towards an unfamiliar ceiling.

'Oh yeah, Project YoRHa. But still, I can't sleep soundly knowing what's happening to everyone. Kuon, Rurutieh, Oshutoru, Nosuri, Ougi, Uruuru, Saraana, Nekone, Atuy, Jachdwaldt, Kiwru, and of course, Maroro'

"Good Morning Director Mashiro" A stern commanding voice breaks Haku/Mashiro from his thoughts.

'I think it would be too much trouble to have them change my name here to Haku, I guess I'll stick with Mashiro for these androids'

As Mashiro turned his head towards the android, he noted how this android wore white elegant clothes.

Said android then nodded towards Mashiro with a polite smile. "I am Commander White, Project YoRHa's android officer in charge, it is my pleasure to welcome you to our headquarters."

"Thank you commander. I apologize if we haven't been in contact for hundreds of years, but we were kinda… Almost wiped out." Haku bowed towards the android who then looked around a as though she saw something unexpected.

"No, we have you humans to thank for our existence and purpose, we observed what happened during the tatari phenomenon, but we were powerless to stop it." A holo-screen instantly appeared in front of the commander, showing androids trying to save humans from tatari. There were also images of humans suddenly turning to said tatari as they were carried by the androids to safety. "We thought we lost our creators, doomed to await destruction out here in Earth's orbit, following our last orders, but your appearance a few months ago changed that."

The commander then stood up and placed her hand towards a wall, prompting numerous holo screens to appear on said wall.

"We detected a signal from one of Project YoRHa's human team, and it was yours Director Mashiro. We observed, and we apologize for being unable to save you 1 month ago." The Commander then presented a screen showing a bird-eye view video of his heroic act of saving Nekone from Vurai's attack. "We were unable to send help due to the last order we received from one of the project team."

Commander White then closed all the holo screens, and opened a new one that was labeled: AUDIO ONLY.

"This is Dr. Isabel Travis, to all YoRHa androids, all humanity is probably dead, a slime monster, or iced. I do not know how long I have before I too become a slime monster or consumed by one. Proceed to stage 2, with contingency B in place, preserve humanity's echo. Continue our legacy. In place of humanity, develop and become better! For the glory of mankind!"

The female voice's last words echoed throughout the room, as Commander White made a solemn salute.

'Isabel. So you didn't make it. However, it was good hearing your voice again.'

"As per Dr. Isabel's last orders, we have been developing ourselves and have created our own spacecraft that we have catalogued as a ship-mech hybrid: we call it the Flight Unit" Commander White then presents several images of a mecha with varying colors, each with the labels 'Flight Unit 01' and so on.

"We have also been observing Earth since that order, but with your psychology and personal preferences with us, we decided not to introduce ourselves early on. "This time, birds-eye images of Haku on a snowy path, being carried by Kuon were shown."

"Your death triggered the nanomachines in your brain, and those machines uploaded your memories to the artificial body prepared for Engineer Mashiro." The medic Android, 1M, enters the room and explains the process of my body transfer.

'So it was my profile preferences. I was wondering why no androids were appearing and dismissed this project as having failed at some point.'

"Director Mashiro, in addition to the original artificial bodies that were created, we at YoRHa added some improvements as covered by Dr. Isabel's last order." 1M explained as several new screens appeared on the wall.

'So there are improvements. I don't remember the team having enough budget to add nerves to the skin, but it's as if I am in my original human body. I can't complain about that, it's all doing well for me after all.'

"To simulate nerve endings, we applied new neurological paths that are used by all androids to determine damaged areas of their body." 1M stated, as an android was showing peeling her skin to show several lined circuitry underneath.

'Ouch. Are these androids masochists? Henry, it was you wasn't it? No. You were a masochist so how-'

"We were also able to develop artificial skin acts like real human skin." 1M grins, as she continues with a very in-depth report of research and applications that androids have made regarding this new feature.

'So that explains this.'

"Due to our research on human culture, to preserve humanity itself, we also made developments in biology, and were able to apply functioning reproductive organs to the artificial bodies, using the built-in DNA structures in said bodies." 1M now smug, waits for my reaction.

"Woah! You guys are really thorough!" Mashiro exclaimed in surprise, discreetly feeling for his 'package'.

"Project YoRHa has indeed exceeded my, no humanity's expectations. You have all fulfilled Dr. Isabel's orders." Mashiro bows in full respect towards 1M and Commander White who smiled in return.

"Our research on our creator's placed importance on sexuality is indeed true. I guess it was the correct decision to stick with the assigned rooms for scanners and the rest of the androids." The two androids the nodded to each other.

'I guess I am about to experience what the female member project members wanted to experience too. I apologize, but I simply cannot, I will instead admire the scanner models from afar!'

With those thoughts Mashiro walked towards the two androids and hugged them.

'SOFT! This is incredible!'

"I thank all of you. I guess it won't be too crazy to say you all added some form of metal to the artificial body's skeletal structure for increased strength, right?" Mashiro jokingly said, as he let go of the two androids who were smiling in satisfaction of a job well-done.

"As expected of the director, we have indeed applied several physical upgrades to the artificial body, thus putting you at par with one of Assault Models."

"Director, the Scanner model's live-reports are about to go online in 5… 4… 3… 2… 1…" Commander White announces, as the director, Mashiro, enters the room by an elevator.

'It seems like the added upgrades to the command center, for it to be able to accommodate this many operator models, from the original 10… Amazing.'

"This is 2S, the country called Yamato is currently under a Civil War with two sides fighting for dominance, based on my observation logs, it's a battle between the General of the Right Oshutoru and the Eight Pillar General Raikou."

"This is 6S, the target named Oshutoru is currently in the province of Ennakamuy, and targets designated: Nekone, Atuy, Kiwru, Jachdwaldt, Rurutieh, Nosuri, Ougi, and Kiwru have been spotted. Targets: Kuon, Uruuru, and Sara- Hwa-" The scanner android in the video screen was about to scream in surprise but two familiar hands covered his mouth.

'I can already feel a headache'

"Master."

"We knew you were alive."

"We can sense your soul in the sky. A soul whose colors draw from the source of all life."

"Without your input, we decided to present Lord Oshutoru with your order on what to do if you were gone." The twins then looked at each other. "Curse Ukon if something happens to me, I haven't been given hazard pay after all."

'I don't remember saying that. But if I was drunk then it all makes sense.'

"No skin."

"Yes, our skin is only for you master."

'A headache is coming'

"Who is the one beside you?"

'Yes. Indeed a headache. Nevermind how they can see my soul, but these two. Ugh.'

"Of course master"

"We will do everything for you. We follow your commands."

"We thank you for allowing us this avenue of contacting you master."

With those words, the pod accompanying the scanner unit, 6S stopped the communication channel. 6S, who had the time to compose himself, gave the twins a two small rectangular devices.

"These devices will blink when we need to contact you, simply bring it to your ear to hear us." The android explained as, the said device started to blink. "Speaking of which, try them out now."

"..."

"Oh, master."

"…"

"We understand, we follow your orders for that is our pleasure."

"…"

"There is no need for words, please shower us physically with your thanks."

"..."

With that last reply, the devices stopped blinking.

AN: I hope you all enjoyed this story that just wouldn't leave my mind on the what if Haku in his past life did some other secret projects connected with his specialty
