She actually look a helluva lot more intimidating than her Meta sister.

If Fusou META has double towers, Yamashiro META has entire fucking castle.

Nooo our cute lil albeit clumsy kitty has gone edgier!!

Oddly enough, her actual personality differs a bit from what her art suggests. Other META ships were driven to insanity, depression, or cynicism, and then there's Yamashiro... whose experience shaped her into a woman who never wants to be hurt again, so she tries to make others into better versions of themselves. Probably one of the most well-adjusted METAs by far.
