Himeko Shirogane

Driven by intense jealousy toward her talented sister, Miko, this wealthy and snobby young girl constantly craves the spotlight. After exposure to Chemical Z, her overwhelming rage transforms her into the psychotic "Princess-sama" whenever her cat, Sapphire, screeches. While she possesses flight and superhuman strength, her most dangerous trait is pulling unpredictable weapons from thin air. Despite her villainous outbursts and attempts to expose the Powerpuff Girls Z, she retains no memory of her monstrous alter ego.
