A/N: A Chapter filled with Da Vinci-Chan only no lewds but some dirty language.

"The Research and Development Department." Da Vinci read out loud as looked at the doors to the building where all the mad science happened. The bad kind of course, not the good kind that led to funny inventions. But the ones that involved inhuman and unethical experiments on one's person.
And from what Takato had told her the guy in charge was a right bastard.
So she and Danzo had been tasked to take the place down, kill Mayuri and then take everything from the place.
"So what is the layout of the place?" Da Vinci asked the Assassin Class Servants as she appeared right next to her.
"The building is divided into various labs, separated by corridors to prevent a chain reaction in case of accidents. Mayuri Kurotsuchi is currently in the main lab, with his Homunculi Nemu." She told her. Yeah, the one he apparently abused on a daily basis. And he considered her the first true artificial being ever created. Despite being left in the dust, by ordinary humans by centuries. It just showed how out of touch the Soul Society was with the rest of this world's Moonlit World.
And now she was going to show Mayuri what a real scientist was if her name wasn't Leonardo Da Vinci.
Da Vinci summoned her gauntlet the black Mysti Code surrounded her arm and soon after her staff followed. "Open Sesame." She said as she punched the doors open with her hydraulic puncher and was met by the many eyes of the Shinigami that operated in R&D. "Hello, boys am I interrupting somebody?" She asked.
Which was responded by them drawing their swords, and yelling to sound the alarm that one of the intruders were here. "So predictable and I thought that you were smart?" She asked the pure air, as the guy that was on the way to hit the alarm was killed by Danzo from having her blade stapped thought his neck.
And so the massacre of the R&D Department commenced as Da Vinci and Danzo tore their way through the scientists. Danzo cutting them down to size, and Da Vinci just froze them to Sub-Zero and blasted them apart with small Ether lasers from her staff.
Honestly, she kept doing it because they kept attacking them despite the warnings she had been giving them to just surrender. But they hadn't.
Did, did Mayuri scare them more than the prospect of death. Okay, that was disturbing to think about if that was true.
Da Vinci and Danzo made their way deeper into building as they headed towards, the main lab as that would where the main source of information and data would be, or at least a way to find a way to it.
Da Vinci watched as one of the remaining Shinigami in the corridor that she was currently in made the smart decision and ran from her and Danzo. "Captain, Captain help us they are slaughtering us." Was all the guy managed to say before Da Vinci saw him simply explode in a puff of gore, that now coated the end of the corridor.
"Honestly so disrespectful interrupting my studies like that." The ghastly form of who Da Vinci perceived to be the Captain of the 12th Division Mayuri Kurotsuchi.
"There was no reason to kill him." Da Vinci said.
"Isn't that a bit hypocritical coming from you? You who have killed a great deal of my men." His raspy voice said as he pointed his long fingernails at Da Vinci.
"I gave them plenty of warning and telling to run, but seemed they rather wanted to die at my hand, than call for your help. And I have never killed a subordinate for requesting help from his superior officer." Da Vinci's voice was stern as she responded while making hand signs to Danzo to continue to look around the facility while she dealt with this mad clown.
"But he like you interrupted my fun time. And so I have to fulfill my duties as a Captain of the Gotei 13 and eliminate any invaders. At least I can have some fun with your body afterward, your certainly an interesting one with that arm and staff yours. I did not know humans were capable of using Kido even channeled through instruments." He said as he drew his sword.
"Ha, oh, you are truly ignorant aren't you." Da Vinci mocked him.
"I think you're the ignorant for actually thinking this invasion of the Seireitei was a good idea, and I am the most brilliant mind to have ever existed and have created wonders you could ever imagine." He boasted.
"Like that artificial being of yours, Nemu was it, please you're behind by centuries human alchemist have already surpassed you by miles. You still need to use drugs, to keep her from turning into a clump of tumors. How pathetic." She further mocked the scientist. She was so happy for the knowledge Takato had provided her about the man
"And now for you insults you shall die, I would never waste this one a low life like you, but you have earned my wrath." He scowled as he fully entered the wide and open corridor that connected the labs. For easier transport of materials, from what she could tell from the tracks embedded into the floor. "Bankai! Konjiki Ashisogi Jizō!" Mayuri announced as unleashed the full release of Zanpakuto. To teach that woman proper respect and not mock his genius. Living humans being able to create a being on par with his Nemu. Rediculus, sure she wasn't perfect, but nothing was as there was always room for improvement. He was going to enjoy dissecting her corpse. And afterward bring her back and test his drugs on her.
"In the name of the Lord, that thing is ugly." The woman said as she looked at the majesty that his Zanpakuto standing behind him as it unleashed its poison. Filling the room put the woman seemed to not be bothered by it. Well, she would succumb soon enough if Jizo's blades didn't kill her first.
"Then you're a blind fool that doesn't appreciate art now kill her," Mayuri stated.
"I don't know art. Listen here asshole I'm Leonardo Da Vinci the omnipotent genius, and your little insect is going to fall to me." She stated, and Mayuri could feel here Reiatsu start to increase where he could barely sense any before. She was about to attack as Mayuri watched as a great amount of spiritual energy began to gather in her gauntlet hand. It almost looked like a Hollow's Cero.
"Jizo attack her now," Mayuri ordered as the woman now named Leonardo announced her attack.
"Uomo Universale!" She fired her attack a ball of energy that collided with Jizo and then it just simply went straight through his Bankai like it was made of tissue paper.
A moment later it was in front of him.
SHIT! Was all Mayuri managed to think before the orb exploded in his face.
"Good riddance to rubbish." Da Vinci muttered as she crossed the crater she made were the so-called scientist had been standing. Though he was not dead as Da Vinci looked down on the badly injured Mayuri who only had his head, the top of his chest and singular arm left as her Noble Phantasm had taken the rest of his body.
"Who the hell are you." He managed to grunt out despite not having lungs to actually speak. These Shinigami were sturdy if nothing else.
"Like I said I'm Leonardo Da Vinci, look at my face you uncultured idiot, who the hell do you think I am?" She asked the dying Shinigami.
"Impossible, not possible." He said as he finally realized who she was. "Nemu." He grunted out as he finally died.
"Well, at least he actually cared somewhat." Da Vinci said to herself as she entered the ruined front entrance of the main lab. Leaving the annoying poison that the caterpillar had generated behind her, it was going to take some time before her Golden Rule(Body) was going to filter that out. The idiot at least had some talent to make a poison that could affect a Servant. However, limited it was, at least it was not Hydra venom or something like.
The room was massive, with what looked to be a massive computer over in the corner, and spread out was various chem areas, and what looked to be an operating table. And on it was a naked woman with a rather impressive bust on size with her own chest, her hair was black and tied up in a ponytail. So this was Nemu if Takato's description of the Humonculi was anywhere near accurate.
Though with her laid out like that she had to guess that either that Mayuri had been doing some experiments on her, or he was doing maintenance.
Well, one thing was for certain, she would definitely make an excellent member of Takato's Harem. And she could always use an apprentice in the ways of proper fun mad science and, learn the magic of this world.
Though now came the trouble of waking the girl, how should she go about it? Perhaps a quick jolt to the system? Yes, that could work.
Da Vinci walked over to the naked woman and placed her non-gauntleted hand on her bare stomach and for a moment quickly filled her being with her magical energy.
And that seemed to do the trick as Nemu quickly woke and sat up, Da Vinci enjoyed the sight of the woman's breasts bouncing with those hard nipples of hers.
She turned her head to face Da Vinci, her expression cold and blank as she asked. "Who are you, and what you doing in father's lab?"
"My name Leonardo Da Vinci and I just killed your father to gain entrance." She fully disclosed. Da Vinci wanted to see how she was going to react to that. If violently she was going to have Takato fuck some sense into her.
"I see." Was all she responded.
"Wait that's it? No declaration of anger to announce your vengeance on me, or crying for your loss?" Da Vinci asked.
"My father was not a good person. He did many unethical things to me and others. So I feel no sorrow for his passing. But he was still my father, so I obeyed and followed his orders. But now that he is dead I do not know what to do. I am artificial being so I can not take control over the 12th Division nor the Research and Development department." Nemu told her in that dull voice of hers.
"Well this might sound inappropriate since I killed your father, but if you have nowhere to go you could always come with me, and my Master we would love to have you." Da Vinci suggested.
"Your Master?"
"Yep, the one I belong to."
"Is he like father?"
"What? No, no, no. He is nothing like your father. Our Master, Takato is kind and will demand nothing from you. Though like us you will probably find yourself in his bed soon, and pregnant." Which Da Vinci knew that she was, she could feel the egg within her growing. And in another two weeks. They would all be showing, and then two months after that, the egg would pop out. And they would see if one had an embryo inside.
"I see, my womb is fully functional and capable of birthing if that is needed, capable of breeding with various species. After many tests." She answered.
Okay, did not need to know that. Da Vinci thought as she heard what Nemu said. "So, you will be going with us?" Deciding to ignore what the Homunculi had just said.
"It seems so."
"Great I always wanted a student. Now could you help with the computer and extract the data from it and put on some clothes." Da Vinci said.
"Of course Mistress," Nemu said as she went over to the side where she pulled out a Shuhakshou from a locker.
After that, she helped Da Vinci begin to transfer the computer's data over to a storage device. Though she did stumble upon a literal copy of Mayuri's brain which contained all of the man's memories.
It was a bit later that Danzo had returned having scoured the facility and having subdued the rest of the scientist. Some dead some unconscious.
Though the Assassin had discovered something interesting that Nemu was talking about. "Those two are off the book experiments, the first is Nozomi the first Mod-Soul and the second is Senna, the Shinenju. I shall bring up her file." Nemu said tapping a few keys bringing up her file and the attached Log.
"The Shinenju is a normal creation during the formation of the Valley of Screams, to hold the discarded memories of the Blanks. Though unlike normal the Shinenju did not cease to exists like it should do then the natural phenomenon ended. But somehow the being self-subbed Senna stayed around. Then she was located after the event ended we found her screaming about wanting to see a boy named Ichigo. She was quickly subdued and brought into my care to understand how she persisted beyond her natural state of being. Though officially she was executed to make sure nothing bad happened for staying around. Various plans are forming in my mind, for what to do with this non-existent entity that exists yet does not, this Nobody."
"Okay, that is concerning. Now what about Nozomi, can you tell me more about her? You said she was a Mod-Soul." Da Vinci asked.
"Yes, she was the first Mod-Soul to be created by Project-Spear head by Oko Yushima. It was discontinued by the Central 46, but Father continued it in secret along with Kageroza Inaba. I assume you killed him."
Danzo nodded, she had seen the green haired man in the lab and killed him with her new Ninjutsu techniques she had gained from being summoned into this world. The Rasengan was an excellent technique, but the man's spatial manipulation was more difficult to fight than needed but after figuring out how it functioned he had been easy to eliminate.
"I see, might I ask who you are?" Nemu asked.
"This is Kato Danzo, an artificial being like yourself." Da Vinci answered. The ninja did not really bother speaking to people she didn't know.
"How is that possible?"
"Nemu you have a lot to learn, though for now let's go and retrieve those two girls." Their return group was going to be a little bit larger than the arrival group wasn't it? Da Vinci thought to herself.
