I re-named the au when I realized "Ironicy" wasn't even a real word. MY LIFE IS A LIE. Anyways here's a poorly-written backstory:

Once upon a time, there was a school, a nice-looking private school, to be specific.
A pair of twins entered the school, and bonded with their classmates.
One of them gained control over time, and saved her classmates once.

More children started attending the school, but things started to get reckless. Students were getting hurt and injured all the time. One kid got amnesia from brain damage
All this blame was put on the staff, either for poor class management or bad school design. However, they did nothing about it.
There was only one option: to sue the school.
The money from the sue was too much: the school couldn't keep afloat, & the principal announced bankruptcy.
Thankfully, there was a bunker under the school, so they continued to make whatever profit they could there...
