Name Etymology
Sachika's surname, Hirasaka (比良坂) uses the kanji 比 "hi" meaning "compare", 良 "ra" meaning "good", and 坂 "saka" meaning "hill". Noteably, the Kanji of her surname are the same used Yomotsu Hirasaka (黄泉比良坂), the slope that leads to the entrance of Yomotsu-kuni or Yomi, the underworld in Japanese mythology. Her first name Sachika (サチか) is written in katakana so the kanji reading of her name is unknown.
Sachika is a young adult who does not physically age, unlike the other clones. She has a more youthful appearance than the other clones, particularly as she is only around 4'5" (138cm) tall. She has a prosthetic right arm and prosthetic left leg, both made of mechanical parts. She has blonde hair in a chin-length bob, with a ponytail-type ahoge on the crown of her head. Her eyes are normally amber, but can change color when her mood changes. Her Cross-key is also different to the other clones, with a more metallic appearance rather than plastic.
Sachika wears a yellow-green thigh-length dress which has white pleats around the bust and hips. The dress has green ribbon straps with yellow piping, which connect on her back into a very large bow. It is fastened with pink buttons up the front. She wears a shoulder bag shaped like Mirai with a pink strap, and green sandles tied with a white ribbon. Underneath her clothing, she wears white and blue spotted underwear and a camisole.
