Sachiko Yonezawa is a supporting character in the series Castle Town Dandelion. She is a newbie yet well-known idol who inspired Hikari to take the same path as her. Despite acting cold towards Hikari, Sachiko later opens up and came to respect Hikari.
- Later in the series, she becomes kinder towards Hikari but has trouble expressing her feelings towards her.
- Sachiko has also shown to care and worry about Hikari, as she once mentioned that if she could, she would take Hikari's struggles and put them on her own shoulders.
- After she worked together with Hikari a good amount of time, Sachiko possibly developed a romantic interest for Hikari. This is seen as she blushed and was curious when Angelica asked Hikari if she had felt a burning and hurting sensation every time she saw someone, and became disappointed when Hikari revealed that she got that sensation when she visited the dentist.
- Shyly, she blushed if Hikari hold her hand or hugged her, like when she did before their concert.
