I'm curios as to the translation.

I think I'll take the lower-right as my headcanon.

I just pick the two above.

To put it simple (order is left to right, then bottomleft and bottomright):
-Just wearing it like a normal mask.
-Wears a mask because she is shy.
-What's beneath the mask is her mechanical parts after her abyssal modernization.
-Wears a mask to conceal her scars.

tbh, the fourth one (bottom right) is what's attracting me right now, I can picture her being shy about it

translate it.... please!!!!

Translation bump.
