Rinny is a polar bear malino who wears a big pink bow behind her head. She has big eyes with black irises and wears a light blue shirt with two white dots. She also has a light pink nose, cheek markings, and belly underneath her clothes.

Rinny has the public image of an extremely likable and extroverted malino. However, this is simply a way of luring her victims in order to torture them. Her motivations are greed and sexual sadism. She has no limits or standards.
