Sapphire

Sapphire is a well-groomed cat who made her official debut in episode 6 alongside her owner, Himeko. As Himeko's favorite pet, she was struck by the black light together with her master. Since that incident, Sapphire can trigger Himeko's transformation by screeching whenever Himeko accidentally hurts Sapphire's tail (much like how Peach triggers the girls' transformations). After being captured, Sapphire was fitted with special collars designed to alter her voice pitch in an effort to neutralize her "trigger" effect on Himeko. However, "speaking" while wearing those collars not only failed to stop Himeko's transformation, but also caused Princess's hair and abilities to change depending on which collar Sapphire was wearing at the time. Seemingly as vain as her master, Sapphire gets angry and scratches anyone who touches her too much, with Himeko being the sole exception. She also spent a romantic night with Peach after he fell in love with her, though she later admitted she only did it to alleviate her boredom. She is represented by Green Gemstones.
