Due to an accident at CERN, Hermoine Granger is zapped through a wormhole and lands on our Earth, in GB. Oddly enough, she retains full use of her magical abilities, with no changes.
The problem?
She stumbles into a Manga store one morning and reads too much Baki(which she finishes up to the Sumo arc before dinner...) As if this is not traumatising enough, she trips, falls, and slams her head into a cover with Yujiro on it. Causing her brain to become corrupted, and her to become obsessed with STRENGTH! Hell. Her Patronus even turns into Retsu Kaioh!
After getting the sh!t kicked out of her by a servicewoman at Alconbury AFB, she decides that pulling a Yujiro and demanding to be flown to the US is not a very good idea. So instead, she decides to go back to her bread and butter: MAGIC!
So she gets a job, rents an apartment, gets herself a phone and in internet connection, and begins accumulating books. Unfortunately, she decides to google herself after getting the hang of the internet, which causes her to utterly lose her sh!t. Not from the fact that she's a fictional character in this world, but, from the *other* stuff she finds that's personally disparaging.
She decides that to clear her good name, the internet must die. And for the internet to die? So do WE!
12 months from now, Hermoine Granger will declare war on OUR world!
Can we stop her if we don't know she's coming?
*This is current adult Heromine, with all her knowledge, experience, and skills. Not to mention the fact that she's given birth twice, which puts her pain threshold way up there. Not the little Hermoine who's going to be easy to fool.
**She has a crap ton of her personal gear since she was moving office when she got pulled through, and she probably has the Time Turner in her possession somewhere.
