Satsuki Takigawa (多岐川皐月)

Ichika introduces her friend Satsuki as "a very responsible and strong person. You can always count on her." She is a brash young girl who often takes the lead of Ichika and the other friends. A painful memory causes her to avoid most boys, despite her seemingly strong personality. Satsuki has an older brother, with whom she apparently gets along well, despite the fact that they bicker a fair bit.
