Well, in canon I'm pretty sure Sakura hated Naruto, and going by her hitting him repeatedly throughout the early episodes, she likely did that too in the Academy at some point, possibly even tried to beat him up with chakra enhanced blows or whatever. Yes, he was basically harassing her, but clearly no one in the entire Academy thought to tell him that (or even considered it wrong apparently).
So having Mariko and Daisuke together despite their clear animosity doesn't seem too out there, all things considered. I'm sure the QM would have mentioned if she did anything particular malicious or noteworthy to Daisuke in the past 7 years, so we can reasonably conclude that she hasn't done anything like that. Yes, she hates him, and he dislikes her, but that's pretty much Team 7's initial feelings towards each other, minus the love triangle and condensed into 2 people instead of 3.
Freaking out over this is natural, plenty of others do, but treating this an actual, serious life-threatening thing is an overreaction, I think. They're kids. They do stupid things. I'm sure someone in the academy has tried to put stuff in their classmate's drink that turned out to be mildly poisonous as a prank; heck, there are real life stories of "jokes" turned deadly. If nothing else, it's entirely possible to be promoted quickly and leave the team.
This. So much this.
Compared to canon Team 7, Daisuke is obviously in the Sasuke position as the attractive and skilled RotY, Mariko is Naruto the underdog who's jealous of that skill and popularity, and Kiba's the Sakura who's there to provide a third perspective and keep the hot-head from blowing everything up.
...Sadly, this comparison creates some unfortunate implications in the long-run... Though Kairi might not mind revising her OTP, I imagine.
Huh, maybe Daisuke can gift Ino a scroll for his Mastered Endless Sword technique? That way she'll have one of his Original Jutsu to help offset any worries of their friendship drifting away.
We've been over this though: giving away Jutsu, especially self-created ones, to your friends is not acceptable in Shinobi culture. These are techniques meant for yourself, your blood, and your direct pupils. You don't pass on techniques to your friends because that devalues those techniques and makes yourself less unique.
Check out Katsuragi's omake "
Great Teacher Daisuke" for this
exact scenario, and why this kind of thing is
not done. Cripes, I bet the reason why GTD wasn't made canon was
because it ends with Ino being made to keep the Scroll - it likely would have canonically ended with Daisuke burning the damned thing because that's what he's
supposed to do. It's
his technique,
his creation, and a major part of
his combat style. Passing that to
anyone is
not how Shinobi operate.
She's a friend. She's not our disciple, nor is she blood-related. Handing her one of our Original Jutsu - one we're likely going to make
extensive use of - is a terrible idea.
It's just not done.
Hell, it might even be a slap in the face - like we're insinuating that since we can't be there with Ino, we think she needs one of
our jutsu that
we created in our stead. Like she wasn't strong enough on her own, and needed something of us to make it as a ninja.
And yet the Hyuuga specifically train to be able to use all tenketsu. They only need accuracy when they're aiming for the tenketsu. When you just want to kill someone or don't care about tenketsu, you really don't need the same accuracy to hit an important organ.
Plus, you forget that the foot is apparently the hardest place to utilize the tenketsu, yet people do it for Tree/Water/Sand/etc... walking and shit. Utilizing other tenketsu isn't that hard in comparison.
Really, this is the last I'll say on this, because we clearly have differences of opinion.
I believe it's more that using the hands is easier because
all ninja use their hands to mold chakra. Therefore, emitting chakra from the hands is made
ridiculously easy because it's what they teach literal children.
And their control has to be impeccable because they need to expel chakra without wasting it. It's a limited resource in battle, after all. So they try to be economical and as efficient as possible because it's a resource to be managed. And the strength to be wasteful with their chakra only comes from years and years of growth and practice as they hone their bodies and spirits to provide the necessary reserves.
So, they train to be ultra fast and precise from the start. Because while they're learning, they need to conserve their chakra and refine their control. To make it as tight and lethal as possible for what little they use while they're young and learning.
And where is it easiest to control just emissions?
The hands and fingers - the very instruments the human body uses to point and direct with.
The style is birthed in the fundamentals they need to be able to train for those emissions. They learn with the hands first because it's easier to develop precision, control and efficiency. Then as the Gentle Fist practitioner gets stronger and more skilled, they are able to emit from other tenketsu, and target opponents in alternative ways than short bursts.
I mean, it's bound to be easier to introduce chakra into a foreign body (with it's own chakra system!) and shred it once you actually know how to be hit the precise targets upon an opponent's body to inject your chakra to set off the cascade necessary to force an opponents organs to shred themselves... right?
The Gentle Fist just builds up to it - a progression as the practitioner gets more familiar with the concepts and methodology of controlling chakra as it's expelled from the body and using it for a variety of purposes in combat. They're dedication to being subtle only accompanies their profession as shinobi - as assassins.
And as to the foot thing - I don't think that the feet are the hardest part to utilize tenketsu in general: just that the precision and control inherent to Gentle Fist are really hard when using the imprecise and awkward foot.. I mean, if you've gotten used to using your hands to do really delicate work, could you easily master doing the same tasks with your feet?
Imagine asking a surgeon to operate on a patient
using their feet. No hands allowed.
Compared to that, Tree/Water/Sand/etc Walking must be ridiculously simple - you're using your entire foot, and you don't need to do anything precise or truly complicated.
