The [[submarine]] I-19 in [i][[Kantai Collection]][/i].

She wears nought but a [[school swimsuit]] with a [[name tag]] on it. Other equipment includes a cannon on her right thigh and several torpedoes around her. She has [[long hair|long]] [[blue hair]] in [[tri tails|triple-tails]], secured with white [[hair ribbon|ribbons]] and tiny ship parts. She also has [[red eyes]] with [[star-shaped pupils|star-like]] [[flower-shaped pupils]].

Her nickname is "Iku" (19 in goroawase, nothing to do with that other [[nagae iku|Iku]]).

She is very often seen holding her torpedos in a way that it goes between her [[large breasts|breasts]], which are sizable for her frame.

She also talks pretty lewdly; her nickname can literally mean [[cum|cumming]] and a few of her lines can easily be (mis)interpreted in a [[tag group:sex acts|sexual]] meaning, which leads to her being portrayed as a sex hungry girl in fanworks.

Her historical model is notable for being the submarine with the record for the most destructive torpedo salvo launched during World War 2. With a salvo of six torpedos, she sunk the USS Wasp (her intended target) while also accidentally hitting the USS North Carolina and the USS O'Brian, severely damaging the battleship and sinking the destroyer a month later from structural damage sustained from the attack.

Her seiyuu is [[misato (voice actor)|Misato]].
