南雲 圭子

Nagumo Keiko is a twenty-eight year old woman promoted to admiral by the new Navy Minister Tougou Tsuyoshi. Keiko's husband also serves in the Imperial Japanese Navy and has more seniority than his wife; however Tsuyoshi nominated Keiko instead her husband due to skill. Keiko's husband serves as a part of her unit.

Keiko is aware of Tougou Tsuyoshi's habits with women and does not hate him for it. Keiko flirts casually with Tsuyoshi but informs him that she belongs to her husband and that the playful actions couldn't become anything else.
