E-2 Stage boss of Kantai Collection's Fall 2014 Event based on the Western New Guinea campaign.
Essentially Harusame (Kancolle) as an Abyssal Ship, referring to how she was the only major Navy casualty of the campaign. Because of being depicted as a dark counterpart to Harusame (Kancolle), she is nicknamed "Warusame".
Has long White Hair in a side ponytail, Purple Eyes, and wears a Midriff-baring two-piece black Serafuku and a spiked Hat. Wields a Cannon on her left wrist. Her rigging takes the form of two creatures with guns and torpedoes on them attached to her thighs.
Whether she has legs or not, she is most often drawn without them.
