Of all the armor sets available in Skyrim, the Steel Plate Armor is my definite favourite in terms of appearance, next to the Ebony Armor set and the Dawnguard Armor sets.

I generally like Heavy Armor over Light Armor by their appearance. I don't mind light armor, it's just that almost none of them really have that knightly image to it, with the Glass Armor set as the closest thing to it, (which by the way looks best with male characters, especially Argonians and maybe Khajiits as well IMO) and the Dawnguard set, to a looser extent.

Anyways, the girl being patted by the steel plate man is a destroyer named Ikazuchi, from Kantai Collection. And the steel plate man is considered an Admiral.

Both series belonged to their respective owners.
