So, it’s not like we’re likely to ever see her again but hey, we could have said the same thing for the Saddle Arabians.

The combination of upswept hair and stark white coat suggest Japanese formality to me. The fan headdress is also a fairly rare style, as far as I can tell.

Her color scheme is white with light blue accents (her irises and her outfit’s main jewels). The headdress itself is quite shiny.

I propose Ice Mirror, as a translation of her native Neighponese name, Kagami no Kori. There’s a mild pun in that: Amaterasu’s Mirror is kept in the shrine at Ise.
