Satsuki Takigawa (多岐川 皐月 Takigawa Satsuki) is a friend of Ichika Tachibana.
Ichika Tachibana describes 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 where 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.
