who is the brown-haired girl to the left of Shikinami?
Isn't that just Ayanami?
...Wait. This base has two Akagis!?
Ah, wait. That could be the Admiral. I don't remember anyone wearing Hakama alongside earrings and a hairclip. Mind you, Suzuya wears a hairclip like that, but her hair is more greenish than brown.
