Overview
Sachiko Koshimizu is one of the girls in IDOLM@STER Cinderella Girls that refers herself as "Boku", which is also used by Makoto Kikuchi from the IDOLM@STER series. Though cute but very proud, she takes pride of herself of being the cutest among all, and is not shy not hide it.
Due to her prideful attitude, she is also witty and sarcastic, seen when she remarked the producer with a "Oh poor you!" comment when she sees the producer lacking the necessary experience to handle the idols. Adding to her beautiful body along with nice ass and knee socks, she is very popular amongst masochist guys. Which goes without saying, she attracted many artists submitting arts related to her, including R-18 ones.
Her tendency to use "boku", along with her short hair appearance, she was once mistaken as a trap.
