What makes Rada different from the other sisters? For one, she isn't a natural but decay-type and the fact that being around her is a health hazard since that's why she's down most of the time. You would be too if you're a Noble gas-wolf made of pure Radon gas. Don't worry though. As long she wears that containment collar, she can safely be around others.
