abyssal crane princess

Final Boss of the Winter 2018 Event in Kantai Collection.

Essentially the abyssal counterpart of Zuikaku, obviously shown by her name (containing the kanji 鶴 "crane" for Zuikaku) and her appearance in the operation that alludes to her historical final battle. Her hair is upwards referencing her crew as they salute as the flag is lowered during her sinking. Also seemingly amalgamated into her being are elements from Musashi (sunk in Sibuyan Sea, 10-24-1944) and Zuihou (sunk off Cape Engano, 10-25-1944), evident in the turret on her back and the hakama skirt that she wears.

Given that the event (and the preceding one) tackles the battle of Leyte Gulf including the encounter off Cape Engano where Zuikaku was sunk, the reference should not come as a surprise.
