She also wears [[black_gloves|black]] [[elbow gloves]] that are [[fingerless_gloves|fingerless]] and [[black_thighhighs|black]] [[open_toe_shoes|toeless]] [[thigh boots]] that bear her name. She has [[long_hair|long]] [[light blue hair]] with long [[sidelocks]] that are tied at the back of her head, [[blue eyes]], and [[headgear]] that [[horned headwear|stick out on top of her head like horns]].

h4. Personality
Her goroawase (numerical wordplay) name is "Fuumii" (フーミィ).

h4. History
The historical submarine was commissioned on June 1, 1944 and was completed on May 29, 1945. She never participated in any major battle in World War II during her assignments to three submarine divisions. Instead, most of I-203's involvement was post-war, participating in sea trials with US Navy submarines and crews through 1946 and later joining a party to rescue and salvage USS [i]Current[/i], suffering engine trouble along the way. Soon after entering caretaker status on February 13, 1946 to be studied by the Americans, she was disposed off as a target off Pearl Harbor on May 21, 1946 to prevent the Soviets from getting their hands on the advanced Japanese submarine technologies.
