This was technically okay'd last season, but to make sure it's not too strong (unlikely) or too weak (likely) or just otherwise won't work, here's my upgrade attempt. 

Style:
[hider=Bronze]
Wind-Carved Glacier
Marrie gains a winter aesthetic and small pieces of armor that look made of ice on her cheeks.

GRADE: Bronze
PHYSICAL: E
ARCANE: D
CHAOS: C
SPECIAL: Masking. The "armor" on her cheeks can be targeted by spells for defensive purposes. Otherwise it's entirely cosmetic.

[hider=Silver]
STYLE: Arctic Storm
Marrie's sweatshirt now flows in the wind like a capote, allowing for melodies to be put on it for protection.

GRADE: Silver
PHYSICAL: E
ARCANE: C
CHAOS: B
SPECIAL: The "armor" on her cheeks can stop physical critical attacks from hitting her head. This special can activate twice per operation.
