Ship Name: Hibiki Ship Class: Destroyer First person: I (Watashi - polite/cool) Silver hair reaching her waist with blue-gray eyes. Wears a white and navy sailor uniform. She wears a navy fatigue cap with a visor; a silver "III" badge is on the left side of the cap. A cool beauty who speaks in a quiet, mature manner. Due to her long time living in Russia, she has a habit of speaking Russian when she relaxes, and it mixes into her conversation here and there. She shows little facial expression. This remains true even in combat, but at the start of a night battle, she lets out a cry reminiscent of a Red Army onslaught. Whether it is the pride of a torpedo specialist or the grit of a veteran destroyer, the fighting spirit hidden within her is strong and hot. She has a cool, elusive personality. She subtly supports her sisters and is the "unsung hero" of the 6th Destroyer Division. She's surprisingly good at going along with the mood.

Ship Name: Dace Ship Class: Submarine First person: I (Atashi - casual/feminine) A main-force American submarine, Dace.

Though her sister ships faced dire situations afterward, she never abandons others to the end. She holds the philosophy that "intuition is important."
