Pardonne and Yanuna have a long history. Pardonne used to be a scientist who made Yanuna. One day, Yanuna broke free from his containment and got revenge on the scientist, transforming him into The female Pardonne we have today.
Pardonne is female and endlessly optimistic. She talks in the third person and always wants to make others happy.
Yanuna is male and endlessly grumpy on the other hand.
Pardonne and Yanuna live with a scientist named Felicia, who cares for them.
Lost memories.
