The One Who Got Away

Mikoto Misaka. She's seen magic, she's seen weird. Did she imagine all that might try to kill her one day? Yes...
But never did she think about what would happen if those forces started to succeed. However, the massive problem is.. when she tried to hide.. she might have picked the wrong castle.. or more specifically.. the wrong school.

One City.. Academy City..
One Wizard's School.. Hogwarts.

Is some conflict about the brew..
Or is war already beginning?
