Kawai Sasami

Japanese name:	河合 砂沙美
Nickname:	Pretty Sammy

An ordinary young girl, Sasami was granted magical powers by Tsunami, who is in line to become queen of a magical realm (planet in the TV version) called Juraihelm.

The OVA and TV versions of Pretty Sammy have a completely re-worked Sasami. In the OAV she is the daughter of a failed singer turned record-store owner named Chihiro Kawai and sister to Tenchi Kawai; in the TV version her parents are Ginji & Honoka Kawai, also record-store owners and she has no siblings.
