If they can find them.

Seems to me that might very well be one of the competitions between the Hidden Asteroid Ninja Academy and the Crystal Academy and Boarding School.
"Alright team, your first event is to locate the competition venue and arrive without being tagged. Here's the file with your clues, find the field in the next 24 hours. This is worth up to ten points per student if you make it to the field untagged. However if you can't find the field by the deadline you will lose twenty."

I'm also figuring that Andrew attempted to use 'wavium to more or less become a were-fox (minus any pesky loss of self control). But since letting your characters have exactly what they want can be a little dull he obviously doesn't get it without side effects. So he can change between his old and new appearances at will, if you consider a day long transformation that leaves you feeling like you just caught the flu to be "at will." Rushable so long as he doesn't mind increasing the severity of the side effects. But since no medicine seems to reduce the side effects he just plain doesn't change forms without need (such that many people have no idea the transformation isn't permanent).
"Doday clath we... huh... haff a code. Huh... ith tho me. Ow! thtop thwapping me!"
"Quick, someone go tell the Headmistress we caught an intruder. Silly impostor, don't look a thing like our teacher."
Besides, who wouldn't want to be a cute lil' fox. Oh, wait, anyone surrounded by a gaggle of girls. (That is the proper collective term, right?)

Will the transhumanist future have catgirls? Does Japan still exist? Well, there is your answer.
