"No," he flat-out answers him. "Not a clue."
"You're trying my patience, boy," the large demon growls angrily. "Have you not done anything new recently, during the day, or at night, which felt decidedly… enjoyable?"
"...Something that felt enjoyable?" he mutters, then the image of Kurenai-sensei and Ino-chan pop in his mind. "Oh! You mean sex! That's what I was doing a few nights ago, and again in the morning. You felt that?"
After an awkward clearing of his throat, the great and somewhat shy Bijū answers, "I sensed it," to which Naruto mumbles, 'perv.' "I sensed it with my previous wardens as well, but their filthy arrogance would not allow them to speak with me as I do you. You will tell me more."
"Really," Naruto asks, slightly skeptical a divine chakra beast would want to know about sex. "What do you want to know?"
"Everything," Kurama says leaning forward and resting his large head on his front paws.
Happy to talk to someone about his experiences, Naruto tells Kurama everything he learned and a lot of what Kurenai taught him. The the Bijū simply listens. Despite the topic, Naruto felt a sort of ease to the conversation and wondered if this was the peace Naru-nii was talking about. By the end, Kurama can't help but say, "as the container of the strongest Tailed-Beasts, I order you to amass more mates."
"What?" Naruto gasps. "I don't even know how it happened to begin with!"
"Learn," is all the beast says before falling to slumber.
SAKURA
'It's ridiculous. He's ridiculous! Who the fuck trains so hard?'
It only takes Sakura three days to realize Naruto is a training fiend, and somehow, more capable than he lets on. His training regiment was as shocking as when she discovered his personal relationship to Hokage-sama. Suffering under the intensity of his training, she learned Naruto can already walk, run and fight on water just as well as on land. Even with her perfect chakra control, it took her all day to walk comfortably on water, and unlike the blond ball of energy, she can't stay on water for longer than twenty minutes.
Sakura also thought creating corporal clones of himself was impressive enough on its own—after all she recalls how he failed the final exam in the Academy—until he revealed the secret to how Kage Bunshin helps him train. Despite, the fact that it would kill a normal shinobi, regardless of rank, clone-learning came across as the biggest cheat she's ever heard of. It explained why she had to continuously adjust her strategy when she and his clones would attack Naruto, which only annoyed her more.
He still wouldn't tell her why he was playing with a balloon just yet, but after watching the way it pops with a massive swirl of wind, she's fairly sure he's working on some form of chakra manipulation. 'That isn't normal,' her stunned brain reasons. Ninja don't learn chakra manipulation at all if they can help it, and when they do, it isn't for years and years in the future. 'How is that idiot doing that when we've only JUST graduated!?'
Sakura learns fast that she can't even keep up with him. Not only does she take more breaks than he does, but his breaks are much shorter. It's little wonder why Sasuke-kun is usually tired by the end of their spars, 'not that Naruto-baka could actually match Sasuke-kun.' But it's apparent that the blond is able to simply outlast him.
'This is ridiculous! For that Baka to train like this, how does no one know!'
It's just so easy to ignore or hate him, Sakura wonders who would believe her if she even told anyone. 'No one,' her mind answers.
KURENAI
It would appear that Kurenai needs more than a week to forget about her monumental mistake. It would be an easier thing to do if Hinata-chan didn't ask every night to train with 'genjutsu-Naruto.'
"Did-did I do something wrong?" she asks on the fifth night. "Is that why you don't want to train me with genjutsu?"
For the fifth time this week, Kurenai was tempted to simply create a genjutsu of Naruto, but as close and knowledgeable to the boy as she's become, she didn't truly understand him and didn't want to risk Hinata possibly recognizing a difference, lest the young Hyūga feels betrayed and all their progress comes undone.
"No, of course not," Kurenai softly starts. "Why would you think that?"
Hinata looks Kurenai in the eyes with a great strength she wasn't capable of weeks ago. "You- ...We haven't trained with genjutsu-Naruto-kun at all this week, and all you'll say is that we need to take a break. I just thought I must've-"
"No, you didn't," Kurenai cuts her off. Despite the immoral lengths the raven-haired Jōnin had to go through for her young ward to reach this level of confidence, she's thrilled about the progress the girl's making, however, now that she's finding her voice, perhaps the beautiful princess needs more of an explanation. "Hinata-chan, how long have you been here?"
"Mnn, a little over a month and a half,"
"And wouldn't you agree we've grown comfortable with each other?"
"Yes," she blushes.
"I know the training we've been performing has certainly helped, but it's all been in a controlled environment, hasn't it?" Kurenai gives the indigo-haired girl a moment to try and grasp what she's saying, so hopefully, Kurenai never has to ask Uzumaki-kun for help again… or even see him if she's being honest with herself. "When you're comfortable, like you feel here with the genjutsu version of Uzumaki-kun, it's far too ideal than what you can expect out in public. Which is why I think you need to attempt befriending the real Uzumaki-kun-"
"Eeeep!" Hinata yips. "I-I-I-I-I c-c-c-c-ouldn't," she stutters, completely bumming the beautiful Jōnin to see.
"Hinata-chan, I stopped because I believe in you. I know you can do this," Kurenai conveys with genuine heart. "Start with whatever makes you comfortable; a simple hello, or ask him how he's doing; however you feel most at ease. I did a fairly good job representing him, so I don't think he'll embarrass you in any way."
"Y-y-y-you..." she takes a calming breath. "D-do you really think so?"
"I know so," Kurenai smiles at her young ward and for the first time that day, she's happy. Happy for what her charming pupil is courageous enough to do as well as for the blond genin Kurenai is all too happy to avoid.
