Kamen Rider Biichu (Peach), Kamen Rider Sazana (Cherry) and Kamen Rider Kenza (Lemon).
Genesis Driver & Sonic Arrow
Kamen Rider Sanzana has Cherry Lock Seed and the female Kamen Rider Biichu transforms using the E.L.S. 03 Peach Lock Seed with the Genesis Driver. She is pink because pink and peach is synonymous in Japan. The upside down heart symbol also goes with Peach as Peaches are thought to look like butts and heart symbols were derived from the shape of a butt. But I could be wrong. Kamen Rider Biichu is the first Pink Rider ever.
