Saeko, following her familial samurai lineage, strictly follows what can be interpreted as Bushido code her character, behavioral patterns, and frequent sayings (e.g "it's a man's decision after all") provides evidence of her strict following of Bushido code. She is very calm and collected, to an almost frightening degree, almost never freaking out or losing her cool in combat. She falls in love with Takashi shortly after the Apocalypse, beginning to use his first name and asking him to use hers. As the second oldest of the group after Shizuka, she acts as something of a big sister to the group, often considering the feelings of other members of the group and ensuring their well being. Throughout the series, Saeko is shown to be a kind, caring, strong and very reliable girl, which is pointed out by other characters. After reaching the East Police Station, Saeko adds a gun holster with a loaded M9 Vertec strapped to her right leg. Later at Saya Takagi's house, Saeko wears a kimono. After leaving Rika's house, her clothing changes to female battle boots with heels, long lace purple stockings, purple gloves, her school uniform top, a skirt that shows the string of her thong and her entire right thigh, a purple lacey bra, and a special belt to hold her sword. At Shizuka Marikawa's friend's, Rika Minami, house she wears nothing but an apron and a thong, and she also puts her hair up into a single ponytail. Over the course of the series, Saeko mostly wears her school uniform however she has changed her attire more than once in the series.


One of Saeko's physical features which are often shown in the manga is her lips, which have a shiny pink appearance. Her relatively long limbs contribute leverage to her powerful sword swings. Saeko has long, straight and shiny purple hair along with a triangular fringe at the front that barely touches the ridge of her nose, and she is also shown to have blue eyes and sizable breasts.
