Foreshadowing, foreshadowing everytime!
A little bit short for butchering, but summed up basically record Minerva's appearance and I.S.A. viewpoint on it I see (rather logical though, Japanese government also has this view in the case M!ichika's arrival in the mirror verse. A sufficiently powerful unknown entity also a sufficiently powerful potential threat)
And of course, special interest on a certain student.
This is one (literally) dense draft.
