Yoshida Chizuru is another close friend of Sawako. She is the tomboy of the group, and she even admits this when Ryuu calls them brothers, where she argues about who is the older rather than that she is not a 'brother'.

In Kurumi's fake rumours it was passed around that she was a former Yankee. She is a close childhood friend with Ryuu Sanada, who is also the son of the owner of her favorite ramen shop. She went to Kazehaya's middle school as well. She has a crush on Ryuu's brother, Tooru. Chizuru is mostly only the slower side of things; she did not realize that Kazehaya liked Sawako (even though she and Ayane planned many events for them) until late in the series, after the 2nd year in their school has started.
