Well, yeah.
It hurts. It really hurts. Forcing chakra out of a tenketsu feels something like being stabbed with a hot knife, only from the inside out, and holding on to the chakra afterward is like a dull burning ache representing pulled muscles in your soul.
... With that said, the elders' fucking gentle-dissuasion jutsu that they've kept breaking out since your mother kicked it makes this feel like you just stubbed your toe. And you remember when you were really tiny, just the effort of breathing and walking around on your own hurt sort of like this.
You don't think you're supposed to remember that long ago, but you think that might have been the feeling of your chakra coils and tenketsu all settling into proper place, so you feel like you're on the right track here for something, even if it feels like crawling over hot coals sometimes.
The hell if you're going to stop just because someone tells you to.
"Make me." you snort, obstinately.
Both Hinatas in front of you look despondent at the rejection.
"You can't.." she stammers, working around the words.
If you were civilian kids, it would be a cute fluster of her not knowing the right words to say.
... Since you're both the children of clans famed for shinobi of great prowess and ocular jutsu, it's instead a visible display of her trying to work out how much to say to make her argument without letting on about clan secrets. She's visibly frustrated, and almost despairing.
"Don't bother." You say, interrupting and focusing hard, until all three Hinata merge into one. You pick your nose with a pinky and flick it away. "There's nothing I'm interested in hearing from you. Get lost already."
Hinata's bangs have fallen over her eyes.
"Shoo, shoo." you say, waving a hand. "I'm the glowing golden genius here, I know what I'm doing." More or less. Sort of.
"Shiny and yellow, anyway. Does she wash her clothes in glitter?" one of the onlookers gathering mutters.
"... You w-won't stop?" Hinata says. "Even though... you're just making it worse?"
You make a rude gesture in her general direction. You're pretty sure. Your vision is swimming a little at the moment. Someone gasps.
"Are you gonna take that from her, Hyuuga!?" Someone yells from elsewhere on the playground.
"..." Hinata says, something too low for you to pick out. Can't read her lips from this angle either. "... people that don't understand... anything but fists..."
"... Eh?" you say.
The words strike you as something you remember from recently... a lecture from the Taijutsu instructor? A couple of days ago, some of the other students had a bout of pacifism when a nose got broken and bloody, and there was a patriotic bout of assuring the new trainees that of course they weren't just learning to go out and hurt people for money, but that sometimes people really, really needed to be hit.
... Wallflower Hinata seems to be unexpectedly taking it to heart, though, as she moves into a stance.
"Fight, fight, fight!" someone cheerfully yells.
... Something about this, though. Er. The Hyuuga...
... Something about attacking the chakra network? You don't know much about the intricacies of their style beyond that, except that they can see the chakra system with their doujutsu and do stuff to it.
Ah, hang on. Hinata wants you to stop.
You throw yourself into an ungainly dodge, wobbling and flopping and rolling out of the way of poking fingers.
Not quite fast enough, as one clips near your wrist and slices away your grip on something like a solid hour's worth of gathered chakra to dissipate uselessly away.
"Hey! Do you know how hard it was to hang on to that!?" you snap, rolling up to your feet.
Hinata doesn't say anything because she didn't let up on the attack and is right in your face.
You reflexively try to escape, realize that you can't dodge everything at this face-to-face range, and then reflexively escape anyway.
It takes you one hearbeat to realize that you just used the Shunshin. You body-flickered away. For another heartbeat you brace yourself against passing out from chakra exhaustion.
Which... you don't feel.
You only moved a couple of feet, which is usually useless for a Shunshin, since the drain is the same up to somewhere near fifty meters away. In combat, especially when you don't throw up some sort of obscurement with it, it's worse than useless as a mobility technique because of how draining it is.
... Only, this time it wasn't.
What was different? You used a much smaller amount of chakra than you should have, less than a twentieth of the usual... and it was very close. So close, that you were still inside of...
Ah!?
The difference was that you moved within the area that your chakra was already clouding up, the zone of control where your chakra filled the air? In terms of the technique... you weren't moving your body somewhere far away. Your chakra system is a part of your body, and so the effect of having part of the chakra still... technically inside of your system, but outside of your body...
Your 'body' isn't constrained by the outer limits of your skin, as far as the technique is concerned?
Low cost, ultra short range combat Shunshin, instead as an emergency escape or non-combat travel technique? And people thought Shisui had something interesting, just because he obsessively trained with it and has a lot more chakra to blow on it than normal!
... Your thoughts race in an eyeblink's time, and that eyeblink of time is enough for Hinata, not caught up in BLINDING FLASHES OF GENIUS like you are, to start whirling around with both hands outstretched, her ruination fingertips at the ready.
Reduced specialty Shunshin costs or not, you don't have enough fuel in the tank to keep pulling that off right now.
So instead you try and spontaneously master the replacement technique, a much more typical close-range evasion jutsu.
Someone helpfully rings a bell as Hinata's fingers drive into a randomly selected bystander's body. He hurks loudly, spasming, and then flops to the ground, unconscious.
"... Na.... Naruto?" Hinata gasps, seeming genuinely shocked for a moment.
She looks at her hands.
Then she looks at you.
Then all expression melts off of her face, until you seem to be staring at a fragile doll posessed by an absolutely murderous ghost.

[ ] "Bye." Time to ditch class for the day. Also tomorrow, probably.
[ ] "Oops." Shrug apologetically. Maybe you can talk this out?
[ ] Pick up a student and throw them at another student. "Riot!"
