Sayoko Shiki

Sayoko Shiki is the Operator of Nasu Unit.

Appearance
Shiki is a light-skinned, thin girl. She has chest-length, straight black hair with two locks that fall over her ears and an uneven fringe that covers her right eye. Two green hairclips prevent her left eye from being obscured too. The rest of her hair is gathered behind her headphones. She has large, brown eyes which she keeps perpetually half-open. She has a tendency to slouch. She normally wears casual, comfortable clothes such as a zipped sweater over a light-colored shirt. In her trion body she wears the standard Operator uniform.

Personality
Shiki is a hikikomori. In the past she lived on the scant provisions sent to her by her family, but after joining Border she began to shop online by herself. Her condition seems to have improved since, as even though she does not show up to strategy meetings at Nasu's house in person, she leaves her own home for rank battles and Border duty. She is not good at dealing with the opposite sex, especially older men, to the extent that it affects her life. On the other hand, with her teammates she comes across as a smart girl who speaks confidently and occasionally playfully in spite of her usual reclusiveness.

Trivia

 * Shiki likes games, water, reading, and online shopping.
 * Her voice actress, Ryō Hirohashi, also voices Yukari Obishima.
 * Her voice actress was not revealed together with her teammates', but only when Shiki appeared in the anime.
