海峡夜棲姫 海峽夜棲姬
First boss of map E-4 in the Fall 2017 Event in [[Kantai Collection]].

Almost certainly an [[abyssal ship|abyssal version]] of [[Yamashiro (kancolle)|]], considering the numerous visual similarities and the fact that she and her sister ship [[Fusou (kancolle)|]] both sunk in the Surigao Strait (which is also the location that Map E-4 represents).

Her damaged sprite (post #2929892) has her alone and rather distraught, echoing Yamashiro's infatuation with her sister.

Frequently paired with [[Night Strait Princess (White)]], the Abyssalized version of Fusou.
