The de facto commander of the Imperial Japanese Navy cruiser 'Unebi' and lead character of the series, Kuki is a conscientious and proper young naval officer who is competent and capable - except when it comes to matters romantic or sexual. The center of an unwanted harem of admirers, as well as the more respectful admiration of her crew, Kuki denies that love between women is possible, but her denials don't quite ring true, especially given how flustered she gets when the women pursuing her make advances upon her.
