|Anime Debut||Crime and Punishment|
Femio was a ballet student at Gold Crown Academy, but he was supposed to be on probation. Despite this, Femio had an irrationally high opinion of himself and claimed to be qualified to be a true prince who loved and was loved by everyone. He seemed to have been especially interested with Duck and Rue.
This caught Rue's attention, and she later tried to steal his heart as Princess Kraehe, only to be stopped by Princess Tutu. Femio assumed the two girls were competing for his affection and, ironically, it was this arrogance that saved him from having his heart stolen.
