So her grandparents are primitive Marisa (basically wild Marisa that's really strong and smart enough to hide and avoid trouble with human or other creatures bigger than they are unless they have no choice) and a Tenko. Her parents are both Tenko. Which explains her resilience and masochist side. Recessive gene… from grandpa made her a Marisa despite coming from Tenko parents. Don't ask how, it just does.
