(A/N) This is the end.
They end up messing with Umbridge more, both collectively, and separately. Emma took great joy in leaving assorted corpses everywhere, mostly small vicious creatures that had attempted to attack her first.
Kakashi tended towards transfiguring assorted things into dogs, mostly replicas of his ninken. He had taken quite a shine to transfiguration.
Fred and George did the less annoying and traumatic stuff, the standard itching powder on clothing, puking pastilles in food, other annoying and embarrassing stuff.
Dumbledore allowed it quietly, pretending to scold them anytime Umbridge tried to get them in trouble, letting them walk out with impish grins and a lemon drop.
When Harry's Occlumency lessons take a trip to tartarus, Emma picked them up herself, effectively building up his, and the rest of the Golden Trio plus Kakashi and the twins, mental shields. They were cautious about doing it at first, but after a demonstration from Dumbledore, where he was unable to penetrate her mind, they jumped on board. It was her or Snape, after all.
With the odd nightmares officially quelled, in part because Emma was interrupting the connection between Harry's and Voldemort's minds, most of the school year went smoothly.
When it seemed all was well, Emma declined the Hogsmeade trip, sending a smirk to Kakashi that had him hurrying the Golden trio out of the castle.
With no one around to witness it, Emma disappeared, teleporting right to the place that had been in all of those dreams she'd intercepted. She quickly checked around the larger area for telepathic signatures, finding that this was the ministry of magic. Some sort of mystery department or something.
Emma stalked cautiously through the area, pausing only for a moment at the arch. A veil, probably leading straight to death. She glared at it a moment, pausing as she sensed as she sensed a bunch of people. An ambush then, she could work with that.
She checked her cuff. She had a few hours before she needed to be back in the castle so as to not arouse suspicion, so she had plenty of time.
"You aren't Harry Potter!?" A rather irritated voice snapped behind her.
Emma smirked, turning around. "Oh no, whatever shall you do?" She kept her close proximity to the arch in mind as she stared the woman down.
"Kill you," Lucius Malfoy, she'd seen him in Draco's mind plenty of times, mostly accidental when he broadcasted an image of his father whenever he said 'my father will hear about this!'
Emma made a dismissive noise, tapping her lip. "Will you?"
"Crucio!" The woman snapped, pointing her wand at Emma, who easily dodged the spell.
"Is that all you have?" Emma asked, taunting her.
She snarled, lunging at Emma, casting spell after spell. Emma neatly dodged them all, and when the woman was close enough, dodged around her, tapped her back, and set her through the arch.
"Bye bye!" Emma chirped cheerfully. "Now, who else wants to die?"
The resulting battle was swift and very very painful for those who weren't Emma. They had enough sense to not cast spells in her direction when someone else was behind her, so that didn't even remotely stop her from stabbing them with a conjured sword.
Emma brushed a few blood flecks off her armor, letting the sword disappear.
"Avada Kedavra!" Was heard from behind her, and Emma assumed it was Voldemort. The spell hit her back, not doing a thing against her armor.
Emma hummed. "Well, that worked well."
She turned around to see Voldemort's astonished face. "Y-you didn't die," he said, narrowing his eyes. "Do you have the same protection as Potter?"
Emma smirked. "Maybe I do, maybe I don't." She had no idea why Harry might have similar protection to her, but she could always get answers later. "So, why're you here?"
"None of your business," Voldemort sniffed.
Emma smirked, getting it from his mind. "You won't get the prophecy. You know why?"
Voldemort narrowed his eyes, but took the bait. "Why."
"Your death eaters are dead," Emma said, gesturing to the corpses around her. "And I can be in two places at once." She created a clone, and it ran off into the shelves, searching for the errant prophecy.
Voldemort growled at her, and sent a few more hexes and curses at her.
Emma dodged them all, barely moving. "Too slow~!" Emma sang, her clone coming out and handing her the prophecy. "You wanted this?" She asked, dangling it from her fingers.
Voldemort growled again, moving closer.
Emma smirked. "Too bad." She dropped it, and it shattered against the ground. A neatly thrown kunai, and Voldemort fell into her trap, falling into the veil. She snorted, checking her cuff. She had time to clean up this mess, but why would she? It'd be funny to see them scrubbing blood off of their floors.
She teleported away, her mind alerting her of other Voldemort telepathic signatures. She went through, destroying them one by one, black energy flickering around her visibly.
Finished, Voldemort well and truly dead, Emma teleported back into the castle, uncaring of the blood spotting her clothing. It'd come out. Maybe. She was wearing red anyway, it wouldn't really matter.
She marched up to Dumbledore, bowing slightly before reporting. "Dumbledore, Voldemort is dead, his soul fragments destroyed. Over half of his Death Eaters are dead, all of the fanatically loyal ones are, at least. I request permission to hunt down the rest."
Umbridge chose that moment to make an appearance. "You can make no such claims, girl." She sneered.
Emma smirked, projecting the last half hour into her mind. "Yes, I can."
Umbridge well and truly silenced while she tried to reorder her mind, Emma turned back to Dumbledore, waiting patiently.
He looked torn. "Fine. Discreetly and quickly, if you can."
Emma grinned. "Thank you. I will be back before the Hogsmeade trip returns." She bowed once, striding off behind a corner before she teleported away to finish her bloody job.
She finished in plenty of time to have a shower and change clothes, so people(mainly Kakashi) wouldn't get suspicious about the blood on her. She knew she still smelled like blood, but it couldn't be helped.
Kakashi was indeed suspicious, but didn't mention it. No one else noticed a thing.
Three days later, it was all announced, Voldemort was dead, for good this time, and his death eaters had all been killed.
Kakashi traded a glance with Emma, who just smirked. He rolled his eyes, going back to finishing his breakfast.
They finished the school year with little trouble, and while whenever she saw a member of the order, they glared at her, probably for her slaughter of the Death Eaters, she had long stopped caring about them. Kakashi regarded her with an almost slight respect, which Emma was pleased about.
Upon returning to Konoha, they were greeted by a 'well done' from Hiruzen, and Emma had a proud smile as she handed over a scroll with promises for better communication. Perhaps it was time for the Shinobi Nations to open up a little.
(A/N) So, that's it. If you actually care what I was planning to do with Emma and Kakashi afterwards, DM me, I'll happily talk about it. I'll put up a poll about what you lot wanna do with this update day, have another update of a different story, or a new story. It will go up on my profile soon after this is posted. BYE!
