Feeling rather pleased with herself, Sakura left Naruto, Kakashi, and Yamato to their own devices and made her way to a quiet corner atop the earthen rampart. For the time being, Naruto was busy grappling with wind chakra for the first time, so he had no real need of her just yet.
"Shadow Clone Jutsu!"
Sakura glanced over the edge of the cliff.
A dozen metres below, under the watchful eyes of Kakashi and Yamato, Naruto had summoned hundreds of Shadow Clones and instructed each one to pluck a leaf from the tree she'd grown. Recalling the scene from the anime, she remembered that his aim was to slice them clean in half, through nothing but direct contact with his chakra.
"All right, enough wasting time," Sakura told herself. "Let's get started."
Sakura's modest goal for the rest of the afternoon was to reproduce the chakra nature change she'd used to destroy the Mōryō's body. She'd already done it once, so it shouldn't prove too difficult, right?
…
By definition, plasma was just ionised gas.
Simply put, when a gas is energised and/or heated enough, its electrons become excited and break free from their atoms' orbitals, creating a seething soup of freely moving, negatively charged electrons and positively charged particles— thus making plasma an excellent conductor of electricity.
"Plasma Style," Sakura said aloud, more to organise her thoughts than anything else. "Come to think of it, aren't fire and lightning already forms of plasma?"
Fire could technically be considered 'cold' plasma.
From previous experiments, Sakura had discovered that she could alter a flame's shape by manifesting an electric field, but that flames barely responded to magnetic fields, due to their low ionisation levels. While fire did contain a bit of plasma, it simply wasn't hot enough on its own.
Lightning, on the other hand, was true plasma.
When a sufficient difference in potential is built up, electricity can discharge and arc through the very air itself. It takes 30 000 volts to break down a centimetre's length of air, turning a normally excellent insulator into plasma, an excellent conductor of electricity.
…
That being said, the various chakra natures are only imitations of actual, scientific natural phenomena. Ninjutsu absorbing techniques can consume lightning and fire chakra, but they cannot swallow up real electricity or actual flames, after all.
"Wind in one hand," said Sakura, recalling Yamato's words when he had demonstrated Wood Style. "Lightning in the other…."
Hang on, she only had two hands.
"And fire in my third hand?" Sakura lampooned. "Who am I, Fiamma of the Right?"
She was once again wasting time, as making references to A Certain Magical Index wasn't very helpful to her case. She needed hard science, not imaginary magic— so, making references to A Certain Scientific Railgun or A Certain Scientific Accelerator would be much more helpful… not!
Sakura scratched her head.
How had she done it, again? She needed to recall the feeling of using Plasma Style, but back then she'd relied purely on instinct, in the heat of battle. If only she hadn't fainted straight afterwards— being unconscious wasn't exactly conducive to scientific reflection.
Unless your name were Isaac Newton, and there happened to be a very large apple above your head.
"System," Sakura called out. "Show me my stats."

Sakura let out a sort of strangled sound of disbelief.
"Just barely over 1 KK?" she spluttered, gaping at her stamina pool stat. "Just how useless is my base body!? I'm only slightly better than a mere Kakashi!?"
Starting at I-cup and onwards, Sakura received from the System half a KK for each cup size she attained, which already accounted for 3.5 KK shaved off the total.
Down below, Kakashi sneezed into his erotic novel.
"Achoo!" he sniffled, rubbing the underside of his nose with a finger. "…someone talking badly about me behind my back again…?"
Technically, things could have been much worse for Sakura.
While most of her stamina was stored in her chest, her entire body had benefited slightly from the bloodlines she'd assimilated, so she was far from a chakra pauper, unlike her original timeline self. If all those bloodline limits were stripped away, her base total at sixteen would hover around a pitiful 0.8 KK.
Not even a full Kakashi!
"At least the System recognises that I've unlocked Plasma Style," murmured Sakura as she scrolled down the translucent display. "And it even gave a name to the attack I used back then… Plasma Railgun…"
For a technique to be recorded in Sakura's panel, she had to have at least reached the introductory level of mastery. The Plasma Railgun Jutsu was a derivative of the Lorentz Gun Jutsu, except that it shot ionised gas the temperature of the sun instead of metal projectiles, so she was just barely eligible, apparently…

"Absolute Extreme Poles Electro-Plasma Thunderclap Railburst: Super Sakura-Flavoured Dango Caster Mk. IV," said Sakura without missing a beat. "With Gold Leaf Sprinkles on Top."
Sakura glanced at the blue translucid screen.

Huh.
The System really accepted it.
