Why do Miss Bellum not 表示する her face?

Either:

A) She is insecure about her face

B) She is ugly

C) SHE HAS NO FACE!

Those are some of the suggestions that may help...
SORRY!

i guess because they just made her that way

maybe they jut leave it like that

Maybe they just decided not to make one???

Well in the real PPG, Ms.Bellum didn't 表示する her face because:a) they didn't have room on the designing board または b) they didn't create a draft for Ms.Bellum.
