Dr. K-Ko

Tentang

A semi-regular character who serves as the primary antagonist of the series. She is a busty scientist and an expert on the Netherworld that is constantly trying to get the "scientific community" to see how bad the four princesses are....for her own status gain. Super Doctor K-Ko wants proof of the supernatural to gain admittance into the scientific elite and what better than one or all of the princesses either captured in her traps or exposed on TV... if her plans didn't have a tendency to go awry.
