Tsunade had a huge grin on her face as she made her way to the makeshift hospital that they constructed while they were rebuilding Konoha. She did not have to worry too much about anything other the overseeing the hospital, so she used that free time she had to gamble and she was on a roll. Such a roll that she completely ignored the fact that whenever she actually won at gambling, there was a fifty/fifty chance that something bad was about to happen. As for where she had gotten all this free time from that was from Naruto and Sakura really took charge of things while she was recovering from using too much of her chakra during the Pain's Shinra Tensei. Having Katsuyu surround herself around the villagers to protecting them was as draining a feat as her Creation Rebirth. Of course, those not included in her protection through Katsuyu were Danzo and his group which she guessed was the reason it took so long for Naruto to get back since Danzo killed the frog that was suppose to tell him that Konoha was under attack. Thus for this traitorous attack against his own village, Danzo and those with him paid the price and were killed crushed to death by the very person they were indirectly helping. Though in a strange turn of events, Naruto coming later actually worked in his favor. During that extra time, he learned what he needed to know in order to beat Pain, otherwise he might have lost. So while she was recovering, Naruto had taken care of leading the reconstruction and Hokage duties while Sakura was managing the injured and searching for survivors that might still had been buried under rumble.
While would take time to make a new Konoha, it was being build around the remaining outskirts of the crater (now a lake) that was old Konoha and the crater that Pain created in his attempt to capture Naruto while in his six tailed form (also turned into a lake). Luckily things like the Hokage Mountain and Memorial Stone were not caught up in the hypocritical attack of Pain who tried to blame all the suffering of the world on Konoha and the Land of Fire, forgetting that there were FIVE big elemental countries not just one. It was not as if Land of Fire was the only nation where their Hidden Village was taking missions; every Hidden Village did this, even his own. So they were all 'funding the war' as he put it since he too ran a hidden village. Pain just targeted Konoha because he wanted revenge and attempted to destroy them because of grudge that he did not want to admit to anyone even himself that he carried against Konoha.
As she entered the hospital, she saw Sakura directing the nurse and doctors like she had been since her and Naruto had finished building this place almost by themselves, since despite Naruto having gone through intense battle with Pain, he was still more able then most ninjas in Konoha at them moment.
"You go check on Kakashi-sensei. Make sure he isn't reading any of those books of his and that Guy-sensei is not bothering him. He's still weak from extreme chakra exhaustion," Sakura said to a nurse.
"Yes, Haruno-sama," the nurse said. Sakura had gotten her own fan club through her actions at helping to rebuild Konoha from the medical ninjas and workers of Konoha.
"Now you go check on Shizune-san. She is out of danger but still not perfectly fine yet," the pink hair combat medic order a doctor. (Shizune is still alive since I never liked how she was killed off so instead she was injured by the Pain that attack her)
"Of course," the doctor replied.
"Hey, Sakura, how's it going?" Tsunade asked.
"Oh, Sensei! You're here early. Are you sure that it's okay for you to be up this early?" Sakura asked, worried. What she did during Pain attack left her sleeping for days and exhausted for weeks even after she woke up. The side effects were much longer then when the time she had been told about when she used Creation Rebirth during Jiraiya-sama and her team up to battle Orochimaru.
"Yeah, I am just fine, but I thought I'd get here early today. I'm going to have to start acting like the Hokage again soon since it would not be right to have you and Naruto take care of everything that I am supposed to be doing," Tsunade told her.
000000000000000000000000000000000000
Entering the head medic office where she spent most of her time going of the medical reports of those here and being brought here when she used Katsuyu to save everyone. She could but that did not completely prevent those from people from being injured, especially those that were already injured before the Pain's attack like Shizune, Kakashi, and Shikamaru who had a broken leg. Then there were those that were injured after the fact like Hinata who really almost got herself killed when she was stabbed in the chest. Sakura healed her on the spot after Naruto had gone six tails but she still needed to be hospitalized for few days afterwards to ensure that there wasn't any irreversible damage done to her.
'Huh? What's this?' Tsunade thought when she noticed that on the desk was a black sphere within a rhombicuboctahedron (a three dimensional shape like a cube only its made of eight triangles and sixteen squares instead of just six squares) as well as what looked like a black cat with yellow eyes on the window sill. Though, the cat might have just been her imagination since she only noticed it for a second out the corner of her eye.
Going over to where the object was, she picked it up then almost slammed her head straight on the desk she picked it up off of.
"What the hell?!" Tsunade yelled as she straightened herself to stand upright to see that there was chain link loop showing almost directly under her breast with chain connecting her to something.
Following the chain links back to the source, she saw her own body laying lifelessly on the ground and what appeared to where the chain was going though she could see the link between her body and herself was broken. Then before she even had a chance to wonder or even figure out that what she was looking at was her Chain of Fate nor that she was now dead since the chain connecting her soul to her body had been cut, the encroachment process began, and rather then happening slowly then speeding up at the end, Tsunade's encroachment (the process of becoming a Hollow) was almost instantaneously as the chain link ate devouring them themselves like Akimichi that had not eaten for three days.
"Tsunade-sama, I…what's going on here?" Sakura asked as she arrived in the office just in time to see Tsunade's soul shatter into million pieces being left to wonder just what the hell was going on. Tsunade's lifeless body was still lying on the ground with the black sphere within a rhombicuboctahedron about a foot away from her hand.
Shocked, Sakura was about to run to get help since to her one Tsunade burst into pieces while another was lying on the ground not moving. Though before the Sanin's second apprentice was able to do so she fell to the floor because something had grabbed her ankle to prevent her from leaving.
Looking over to what was stopping her, she saw that it was what appeared to be slug no different then Katsuyu (expect this slug was human size not three hundred feet tall) around her ankle. Though soon the slug became taking on a more humanoid shape and eventually took the shape a blond hair woman wearing a mask around her face. Holding up Sakura by her ankle only she then blocked one attempt at the Chunin trying to escape from her grip with her free hand catching the fist. While the second attempt also was Sakura's fist going straight through hole that located in the area she was trying to hit. In a last ditch effort, she bought down her on free leg on the figure head speeding up the process of the already cracking mask on their face.
"Tsunade-sama" Sakura asked in shock that the person holding her captive was her own teacher.
"That's right, Sakura. It's me, your teacher, and since you saw what happened, I can not let you leave here. That would prove most problematic for Lord Orochimaru," the Tsunade Arrancar told her; the only remaining part of her hollow mask was three petals located on the right side of her head. The object lying near her lifeless body was in fact the Hogyoku that Orochimaru and Aizen created with the same addition that Aizen's own Hollowification Kido had added to it to release the dark side of person while sealing away the good leaving the now evil side of the person loyal to him.
"Tsunade-sama, fight this off! You do not have to do this!" Sakura yelled.
"Fight what off? I am a servant of Lord Orochimaru," Tsunade said and a smirk came across her face, "As will you be soon. With the two of us, Lord Orochimaru will be well in on his way to having a force be reckoned with."
Sakura did not know about the mental side effect of the Hogyoku created by Aizen and Orochimaru but she was about to learn then first hand as grabbing the device, which now that it had done its job, had no effect on Tsunade.
The blond arrancar pressed it against Sakura's chest dropping her to the ground where she experienced the pain of the final stage of encroachment process but strangely enough her soul was not separate from her body. She was undergoing the Hollowification process while still in her living body unlike Tsunade. From the point of impact, bark began covering Sakura's skin as her hair, fingernails, and toenails. They were transformed into cherry blossoms. Sakura had become a hollow that was a dryad based off the meaning of her name 'Sakura', which meant cherry blossom. Her Hollow Mask, which formed a white substance pouring out of her eyes and mouth, had a single horn sticking out the middle of her forehead.
Once the mask had fully formed, Sakura's screams of pain stopped and she was lying there almost as lifeless as Tsunade's body before the bark receded from her body and her hair, fingernails, and toenails returned to normal. Also, when her mask broke, the only thing left was the horn and area that covered her forehead.
"Awaiting your orders, mistress," Sakura Arrancar said as she kneeled to Tsunade who she seemed to consider her superior in the same way Soifon did with Yoruichi.
"Grab my body over there. We are leaving to report to our master," Tsunade ordered her.
"Yes, Mistress," pink hair arrancar said, doing as she was told.
Thus in the span of just a few minutes, Konoha had lost its two most skilled medical ninja to Orochimaru. As for why, no one knew what happened until it was too late, Yoruichi who was there earlier set up sound proof seal that activated shortly after Tsunade picked up the Hogyoku. The reason Sakura was able to hear anything was because she was within the area at the time.
000000000000000000000000000000000000
'Now I did not expect this, but it prove to be quite useful in the long run,' Orochimaru thought. He only originally planned for Tsunade to become his servant in the army Aizen and him were building but Sakura was added bonus since she could be used against Naruto who everyone knew he had a soft spot for.
As for the Arrancar outfit that Sakura and Tsunade were wearing, they received training from Soifon and Yoruichi on their new Shinigami and Hollow powers. Tsunade had on a large metal choker that had black strap connected to gold ring which was then in turn connect the two strip of fabric that could barely be called a bra. That being since the 'bra' barely covered half of her breast leaving the other half exposed. On her arms were shoulder length gloves that where the middle fingers were black and line from that point flow all the way up the gloves. A thong was the only thing she had on to cover her private area and nearly thin length boot on her legs. Sakura's Arrancar outfit was similar to her mistress's only without the choker or ring. Also her shoulder length gloves were all white and unlike her mistress she had a dress on, only leaving part of her thigh exposed. Also, one more thing that differed from Tsunade's Arrancar outfit was that she had white hiate in place of her old red one with the symbol for Aizen's and Orochimaru's Arrancar Army carved into it.
