Sakura felt as if her head was once again submerged in the bubble of water used to torture her when she first arrived at the Root hideout. The roaring in her ears would not quiet and her heart thumped wildly with adrenaline. With her lungs feeling like they were made of lead, she struggled to breathe as her eyes glued themselves to Sachie.

The mission was simple: get information, don't die. Sounds easy, right? Sakura laughed bitterly to herself at the thought as she expertly packed her weapons into a small, tan pouch. It had been two days since she reported her discoveries in Kusakagure to Kakashi—two days since she was assigned to infiltrate what remained of Root.

As if the mission wasn't intimidating enough, Kakashi gave her strict instructions to not share the details with anyone. But keeping secrets left a sour taste on her tongue, especially when those secrets also involved her investigating her own friends.

She was warned that this would happen—that this high level of treason met no one was safe from being a suspect, even the friends whom she trusted with her life. Kakashi echoed her thoughts but as Hokage, he couldn't play favorites like that. He was even a little taken aback when she reported that she had already told Naruto, but eventually agreed that it was for the best as he was already in training to be Hokage.

Scanning her room, she silently hoped that this mission would be over soon and that she could return home and finally live as a Konoha medic. No more traveling, no more fighting. Sakura yearned for that type of simple life. But she couldn't help but wonder if she would actually be happy if things were suddenly that simple. Or is there some masochistic part of her that enjoyed the chaos of life-threatening missions?

With one last look at her apartment, she locked the door and set out. Before heading to the Hokage's office to receive last minute instructions from Kakashi, she had one quick stop to make.

Her stroll to the hospital was refreshing, the familiar route giving her a sort of comfort. When she arrived at the front steps of the building, the feeling only strengthened. It was here that she discovered her true talents after years of mindlessly following her teammates around. It was here that she found real purpose.

Sakura found Tsunade sitting in her office, sitting with one elbow propped on the desk supporting her cheek. Her other hand was scribbling vigorous letters in her open notebook.

"Finally decide to pay this old lady a visit?" The head of the hospital asked without looking up from what she was writing.

"I'm sorry, Tsunade-shishou," Sakura bowed her head. "Things were just a little hectic."

"So I've heard." The blond Sannin closed her notebook with a soft thud before resting both elbows on the table and leaning her chin onto her fists. Her brown eyes that met Sakura's softened and a small smile played on her lips. When she gestured for the pinkette to sit at the chair across from her desk, she obeyed.

"Kakashi's already filled me in with most of the details. Are you heading over there now?" Tsunade asked once Sakura was settled in the chair.

"Yes, shishou. I plan to start the mission as soon as I go over the last details of the plan with Kakashi-sensei."

"Good." The blonde woman studied Sakura for several long seconds before adding "how are your chakra reserves?"

"There's plenty. I've been able to store a bit more than usual since I haven't had to do much healing in the other villages' hospitals." As she replied, Sakura absentmindedly grazed the violet diamond seal on her forehead with her fingertips.

In a rare display of affection, Tsunade reached across the desk and lifted Sakura's chin gently until their eyes met. Sakura had been avoiding her gaze, afraid that her master would see past her facade that hid the anxiety she felt about her upcoming mission. But the older woman was too smart to fool.

"You're nervous." Tsunade stated, allowing her hand to drop from where it held Sakura's chin.

"Yes." The pink-haired kunoichi swallowed uncomfortably.

"Good."

Sakura tilted her head slightly, puzzled. "It's good to be nervous?"

"Of course it is. I would be concerned if you weren't nervous about having to investigate your own comrades."

"Ah, that's right." Sakura nodded solemnly.

"Now tell me, why did you actually stop by here? I know it wasn't just to see me."

Sakura smiled sheepishly before pulling her pouch to her lap and digging into it. From it, she produced the small vial of poison that she had collected from the man she fought several days earlier.

Handing it to her master who eyed it curiously, Sakura explained, "I fought with some rogue ninja on the way here. One managed to escape but I was able to subdue one. The only thing is before I could even get any information, he swallowed a pill with this in it and within seconds he was dead. I've never seen anything like it."

"And you want me to analyze it, correct?"

"Yes, I think that if we can trace the origins of the poison, we might be able to learn more about who we're dealing with."

With a nod, Tsunade pocketed the vial before standing from her desk. Sakura followed suit.

"It will probably take some time to analyze it but I'll assemble a team right away."

"Thank you, Tsunade-shishou."

The older woman smiled and rounded her desk until she was standing right in front of her past student. With two fingers, Tsunade once again lifted Sakura's chin until their brown and green eyes met.

"Oh how you've grown," The blonde spoke softly as she clicked her tongue. Sakura smiled warmly in return. "Come back safe, okay?"

"Of course," Sakura reassured before adding, "Do you want to bet on it?"

Tsnuade let out a noise that sounded both like a scoff and a laugh.

"Don't start with me, Sakura," The former Hokage playfully scolded as she waved her hand lazily in the air. "Now go on, you have a job to do."

"I'll see you soon, Tsunade-shishou." With a bow, Sakura exited her office but before she was past the door frame, the voice of her master stopped her in her tracks.

"And Sakura?" Tsunade called after her.

"Yes?" The pink-haired woman poked her head back in to study the older woman's face whose features were now softened yet serious.

"I'm very proud of you."

For several beats, Sakura stood deathly still before finally remembering to breathe. She had only heard her master praise her this way twice. Once immediately after the war and another time when Sakura challenged a stranger to a bet and won.

"Thank you, shishou." After a brief moment of hesitation, Sakura ran back into the office and threw her arms around Tsunade.

"Thank you," Sakura repeated in a whisper as the master-student duo embraced.

Once the shock of her student's arms gripping her form with much more strength than necessary was over, Tsunade tightly returned the younger woman's hug. Her chest filled with a maternal affection she always forgot she was capable of.

"If you're really thankful, you'll come back unharmed. I don't want to waste chakra healing you, got it?"

Giggling lightly, Sakura replied, "got it."

With a final wave of her hand, Sakura strolled away from her master's office, out of the hospital, and towards the Hokage's office.

When she reached Kakashi's office, she was greeted with the sight of him and Tenten speaking in urgent, hushed tones as they huddled over the large desk. Peering closer, she saw that their focus was on an assortment of weapons, lined neatly in a row.

"Is everything okay?" She questioned after several seconds passed with neither noticing her presence.

Tenten jumped at the sound of Sakura's voice whereas Kakashi simply waved for her to come closer, eyes still trained on the objects before him. As she approached the pair, she gave Tenten a quick side hug, which the weapons unit coordinator returned eagerly. However, their expressions grimmed immediately as their attention refocused on the weapons.

"These are the konoha advanced weapons," Sakura observed as her eyes trailed across the objects.

"Yes, we've been comparing them to the paper bomb sample you provided," Kakashi's eyes raised to meet hers, a solemn look darkening his expression. "You won't like what we found."

Her blood ran cold at the tone in Kakashi's voice but she nodded to signal him to continue.

But it was Tenten who began to speak next. "The paper bomb you brought isn't actually from Konoha."

"Isn't that good news?" Sakura's shoulders sagged in noticeable disappointment when she saw Tenten shake her head.

"You see, it may not have been from Konoha but it was a near-perfect replica of our line of advanced weaponry. So whoever you're dealing with not only was able to access our weapons but they're also knowledgeable enough to recreate them."

Tenten's words hung in the silent air for what felt like several long minutes, before the quiet was interrupted by the Hokage's exasperated sigh.

"Sakura," Kakashi's voice came out measured and cautious as the pinkette's eyes fell on him. "There's more."

Tenten took that as her signal to speak. "When we tested the substances used on their paper bomb, we found traces of another element. This is something we've been working on for a long time, long enough that even Neji knew about it and helped with its development."

At the mention of their fallen comrade's name, Sakura and Tenten exchanged sympathetic glances. Prior to the war, neither of them had been particularly close. However, the grief brought them closer over the years as they mourned the tremendous loss suffered by the village.

At Sakura's encouraging nod, the weapons expert continued, "For years, Neji thought it would be a good idea to create a special type of weapon that's strong enough to counter visual dojutsu. He was afraid that enemies using stolen eyes would be able to overpower us. We weren't able to make any progress when he was still here but over the last year, we were able to develop this."

From the row of weapons on Kakashi's desk, Tenten carefully picked up a small, round ball and held it up for Sakura to see.

"You're saying that could counter dojutsu?" she asked as she eyed the object in disbelief. It looked so tiny and unthreatening.

Tenten nodded solemnly. "It's a mineral bomb that releases a thick smoke when activated—smoke thick enough to essentially blind almost all eye techniques and render them useless."

Sakura's gaze on the bomb widened. "What about the Sharingan?"

"Yes, including the Sharingan." Kakashi spoke up now and both kunoichi turned to watch him.

"But these people are after Sasuke! What if they use it on him? What if we're too late and they've already used it on him?" Sakura was rambling now as unthinkable scenarios shuffled through her mind. The image of Sasuke's battered body after his battle with Naruto stuck to the forefront of her brain.

"Calm down, Sakura." The Hokage held up his hands to signal her to halt her rapid speech. "Sasuke's one of the strongest shinobi, he won't go down that easily."

"But you know that he relies on his visual prowess too much sometimes."

The sensei-student duo met their gaze, likely flashing back to the same day. It was several months before Sasuke left and like most days, Team 7 was sparring on the familiar training grounds with Kakashi nonchalantly reading his book under the shade of a nearby tree. As the trio battled, the Hokage finally piped up and suggested that Sasuke try taijutsu without the use of his Sharingan.

"You never know when you might have to fight without it," Kakashi had said.

At this, Sasuke seethed with anger. "I know that. I'm prepared for it," he had replied through gritted teeth.

"How can you be sure when you've used the Sharingan during every training session so far?" The ex-sensei didn't bother to look up or even flinch when Sasuke's kunai went flying towards his head. With a simple movement in his neck, he dodged the weapon and allowed it to lodge into the bark of the tree behind him.

The training session ended an hour later after Sasuke, Sakura, and Naruto continued their taijutsu spar, none of them mentioning what Kakashi had said earlier. But Sakura continued to notice the red flashes of Sasuke's Sharingan.

In the present, Kakashi and Sakura continued to exchange their worried glances before Kakashi's eyes upturned in a smile.

"Sasuke has always been prepared for anything in a battle. It takes a lot to take his focus off a fight, remember that." he reassured.

Sakura swallowed and nodded to acknowledge his statement. Kakashi was right, she needed to have more faith in Sasuke.

At the silence that followed, Tenten began to gather the weapons before sealing them into a scroll that she produced from where it lay beside her feet.

"I know I can't know the details of whatever mission you both are discussing so I'll head out now." As the black-haired ninja passed Sakura, she gave the woman's shoulder a soft squeeze. "Good luck and stay safe. I'll see you back home soon, yeah?"

"Yes, thank you." With a final smile and hug between the two women, Tenten was gone, leaving the office and closing the door with a soft thud.

"What do I need to do for this mission then?" the pinkette finally asked as she turned to look at her former teacher once again.

"We need to start with getting more information," Kakashi said as he rested his elbows on the desk and clasped his hands in front of his mask-covered mouth. "We don't know anything about who we're dealing with so we'll need to get you on the inside somehow. I'm sure you've already devised a plan these past couple days?"

Sakura nodded at this. "Yes, I was planning on setting a trap and then using this," she raised her hand to point to the violet byakugou seal on her forehead. When Kakashi cocked his head to the side curiously, she explained further, "First, I'm going to use myself as bait and lure some of the ninja to attack me. I'll capture one of them, get information, then use my chakra reserves to change my appearance. From there, I'll infiltrate them disguised as one of their own."

"Okay," Kakashi said with a slight shrug.

"Okay?"

"Yes, it sounds like you have this all thought out and I don't see an issue with it. You have the training and experience to successfully subdue the attackers and I know that Lady Tsunade has taught you well. I think we can go ahead with the plan."

Sakura drew in a sharp breath, shocked that Kakashi so readily agreed with her. Sure, she has grown a lot and was easily regarded as one of the strongest kunoichi in the village, but standing in front of her former teacher made her feel almost as if she was twelve again, immediately freezing at the sight of danger and crying to be saved.

As if sensing her thoughts, Kakashi's eyes softened and his lips drew into a smile that wrinkled the fabric of his mask. "Believe in yourself, kiddo. You're stronger and smarter than you give yourself credit for."

Her face brightened at the compliment as she soaked in the warmth that spread across her cheeks.

"Thank you, sensei."

As the Hokage's smile widened, she couldn't help but notice the slight creases that formed at the corners of his eyes. It seemed as if running a village was starting to age him. The thought left a bittersweet taste on her tongue.

"Alright," he sighed as he stood from his seat and rounded the desk. "I'm going to have Pakkun come with you until you're able to capture one of the ninja. He'll be able to bring them back to me while you continue with the mission."

With a quick prick of his finger that drew tiny drops of blood, Kakashi began to expertly weave hand signs before crouching to place his palm against the ground. Immediately, black markings sprouted from his hand and etched into the floor below. The summoning jutsu produced a puff of smoke that cleared swiftly to reveal Kakashi's ninken, a small dog wearing a Konoha headband.

"Sakura," Pakkun greeted, shaking his wrinkled snout as he sniffed his surroundings. "Smells like we still use the same shampoo."

"I told you not to mention that anymore!" Sakura shouted back, pointing a threatening finger at the ninja hound before her. Her other hand curled into a fist at her chest.

"Now, now. Settle down, you two," Kakashi stepped between them with raised palms. "We have a mission to attend to, remember?"

Sakura glared at Pakkun but kept quiet. After flashing her a smile so small that the only indication it happened was the slight upturn of his eyes, Kakashi turned to Pakkun to explain the details of the mission.

The ninken was to follow Sakura at a distance until she is able to restrain one of the enemy ninja. He'll wait until she gathers enough information to assume their identity. Once her transformation is complete, Pakkun was to bring the captive nin back to the village and report immediately to the Hokage's office. From there, Sakura would be on her own.

"It's too risky to have you communicate with me while you're on the inside but hopefully it won't be too long before you can get the information we need and get out," Kakashi explained to her after he finished briefing the ninja hound. "Remember, our main goal is just to gather intel. I don't want you trying to fight them without backup."

"Got it," Sakura assured with a nod, her expression sober.
