A temporary outpost on the border of the Land of Water.
"How are you? Do you feel uncomfortable anywhere?"
"Hmm... I don't feel anything."
"How about this?"
"Hiss..."
Has something changed?
"No, it's just a little itchy..."
In the narrow but brightly lit room, Naoki Senju lay shirtless on an operating table, the sealing array on his abdomen manifesting, as two delicate, white hands moved over his body...
Tsunade and Shizune would occasionally press on certain parts of the body or collect a little blood and hair from Naoki Senju in order to gather and integrate the body data of the Jinchūriki.
Although Konoha possesses the strongest Tailed Beast, the Nine-Tails, the number of Jinchūriki is not large due to the power of its sealing Ninjutsu. The data on Jinchūriki that Tsunade collected was so scarce that it only included Kushina Uzumaki. As for the Jinchūriki of other ninja villages, killing them is possible, but capturing them alive is absolutely impossible.
Now that there's a ready-made Three-Tails Jinchūriki right in front of her, how could Tsunade not make good use of it... ugh, let's do some scientific research on it.
"Okay, hurry up and put your clothes on."
As Tsunade spoke, she casually touched the sealing pattern on Naoki Senju's abdomen, which was actually his abs, just like a seasoned female hooligan.
" Sister Tsunade, you'll corrupt Sister Shizune like this." Naoki Senju picked up the neatly folded clothes and put them on without any hesitation.
" Shizune, what do you think?" Tsunade organized and summarized the data she had collected, writing it into a separate scroll.
"Hmm... I think Lady Tsunade is right." Shizune, who was storing blood samples, was caught off guard by the sudden outbreak of the 'battle' and answered.
But Tsunade looked at Naoki smugly, her meaning clear: See? Shizune is always on her side.
" Sister Shizune, you're spoiling Sister Tsunade too much. If this continues, Sister Tsunade will become more and more arrogant."
However, before Shizune could answer, the domineering Tsunade forcefully grabbed Naoki's head:
"You little brat, you've got some nerve, daring to talk about your older sister like that now. If you don't teach me a lesson, you'll only get more arrogant in the future."
"Oh? How does Sister Tsunade intend to punish me?"
After straightening his haori collar, Naoki Senju snapped his fingers, and several gentle streams of water condensed in the air, wrapping around Tsunade's wrists.
He pinched Tsunade's smooth, delicate chin, gently lifted it, Naoki Senju looked directly into Tsunade's eyes with an aggressive gaze.
"Or rather, how does Sister Tsunade want to be taught a lesson?"
"Eek~" Such blatant teasing forced Shizune, who was focused on her work, to be distracted. After stealing a glance, Shizune blushed and covered her eyes, but through the gaps between her fingers, she could still barely catch a glimpse of the increasingly erotic scene.
Tsunade smiled dismissively. This level of Water Release only required a slight exertion from her...
"Um?"
Seeing the still intact stream of water on her wrist, and with Naoki Senju grinning maliciously before her, Tsunade increased her strength and tried to break free again.
" Sister Tsunade, these Water Release Chakra all come from the Three-Tails within me. You won't be able to break free without using a lot of force."
"Hmph, brat, you really underestimate your sister." Tsunade back slightly with a touch of arrogance, freeing her chin from Naoki Senju's grasp.
Then, without Tsunade exerting any force, the continuous stream of water wrapped around her wrist was shattered into several pieces by the terrifying force, losing its Chakra support, and spilled onto the ground like ordinary water.
"How about that? Don't think that just because you've become the Three-Tails Jinchūriki you can overcome my Superhuman Strength. You need to learn to be humble, brat."
Naoki Senju also gained a new understanding of Tsunade's strength. He could easily create massive destructive power in an instant by simply using Superhuman Strength, but he could only admire Tsunade's ability to control and use Superhuman Strength at will.
"Understood. Sister Tsunade is the strongest Shinobi World, and she will surely shine as brightly as the sun and moon for all eternity."
Although they were all compliments, Tsunade had become familiar with Naoki's speaking habits after spending so much time with him, and she knew there was definitely a hidden meaning in his words, and they weren't exactly kind.
"You brat, how dare you mock your older sister! I'll teach you a lesson you won't forget. Stop right there!"
Tsunade's punches are not so easy to withstand. Naoki Senju had his fill of verbal sparring, but his body didn't want to get hurt anymore. He slipped away like a gust of wind, with Tsunade hot on his heels.
The two ran out laughing and joking, leaving Shizune to finish the remaining work. Shizune, who worked hard without complaint, naturally had no complaints, but she couldn't help but reveal a hint of envy in her eyes.
" Lady Tsunade and Lord Naoki have such a good relationship, but... there are just some times..."
Suddenly, Shizune's pretty face flushed red, and visible steam rose from her head. She also packed her things even faster.
A moment later, Shizune finished organizing the last file, took out a sealing scroll and sealed it all away. After doing all this, she wiped the fine beads of sweat from her forehead and let out a long sigh of relief.
"Finally finished. I wonder if Lady Tsunade and Lord Naoki are back yet..."
Knock knock knock--
A sudden knock on the door interrupted Shizune's thoughts.
Who could be knocking at this hour?
Shizune cautiously opened the door a crack, only to see a familiar yet somewhat unfamiliar figure. However, Shizune managed to recognize him through the presence of his top henchman, Kabuto Yakushi.
"You are... Lord Orochimaru?"
"So it was Shizune. Where are Tsunade and Naoki?" Orochimaru's voice sounded weak, but the chilling aura remained undiminished.
" Lady Tsunade and Lord Naoki have gone out on business. They'll be back soon."
"I see. Could I borrow your Medical Ninjutsu laboratory for a while?"
"No problem, Lord Orochimaru, please feel free to do as you please."
Orochimaru didn't stand on ceremony, thanked them, and was then helped inside by Kabuto Yakushi.
Shizune was very concerned about Orochimaru's situation, not because she was worried about Orochimaru safety, but because she was wary of some unknown situations.
They took out a pre-prepared signal flare, Shizune walked outside the base, and set it off. A small firework bloomed in the low sky, and Naoki Senju and Tsunade, seeing the signal, rushed back to the base immediately.
A moment later, Naoki Senju and Tsunade looked at Orochimaru with strange expressions. Naoki Senju, in particular, thought Orochimaru had truly become Aunt Snake this time...
" Orochimaru, what's wrong with your... appearance?" Tsunade asked cautiously, choosing her words carefully.
If Orochimaru's Chakra hadn't remained largely unchanged, she wouldn't have recognized her longtime teammate.
"This is a forbidden technique I created myself, the Living Corpse Reincarnation. No matter how my appearance changes, I am still me, so you don't need to worry." Orochimaru leaned weakly against the headboard, possessing a strange, almost sickly beauty...
Naoki and Tsunade exchanged a knowing glance at Orochimaru's towering breasts; it was truly difficult for them to view Orochimaru with the same perspective they had before.
Unexpectedly, her teammate of many years suddenly turned into a cute, big-breasted girl, Tsunade with mixed feelings ( Jiraiya was overjoyed).
