E-4 Stage boss of [[Kantai Collection]]'s Fall 2014 Event based on the Western New Guinea campaign.

She has [[very long hair|very long]] [[white hair]] and [[orange eyes]]. She wears a [[short dress|short]] [[ribbed_dress|ribbed]] [[black dress|black]] [[sailor dress]] with long [[detached sleeves]], black gloves, and [[black thighhighs]]. Her most prominent feature is her giant black [[armored boots|armored]] [[knee boots]].

Speculated to be [[shoukaku (kancolle)|Shoukaku]] as an [[abyssal ship]]. Shoukaku was sunk during the "Battle of the Philippine Sea":http://en.wikipedia.org/wiki/Battle_of_the_Philippine_Sea, which is what E-4 represents. Aircraft Carrier Water Oni also resembles Shoukaku visually (Similar facial structure and hair style, bulky footwear, hair ornaments across her head exactly where Shoukaku's hairband is). Though her high armor would make her a closer fit with [[taihou (kancolle)|Taihou]] who also sank in the same battle.
