[WHAT'S A SCHOOL ID........



Okuni masks her own ignorance with a imperious sort of nod as if to say 'yes, i totally want to see your school ID']

If you really did receive that letter, then you should have a magic power as well.

[another IMPERIOUS LOOK, but this time expectant]

The best truth is the kind one can see with their own eyes, don't you think?

[jk now she just wants to see keiichi do something cool with his POWER. maybe it's a power that can light things on fire, that would be great]
