Petrarca Anne Erdrant III

Petralka Anne Erdant 3rd (ペトラルカ・アン・エルダント三世?) is the empress of the Holy Empire of Erdant.

Petralka is 16 years old with a doll like face and a childish personality. She hates being called a "Young Girl", and even attempted to kill Shinichi for yelling that at their first meeting. Her chest is small and she cares too much about it. She is one of the first in the Holy Empire of Erdant to master the Japanese language.

From the start she has shown an interest in Otaku Culture, but didn't have a full understanding of it. As a result, she would visit Shinichi to read manga together. Because Myucel started learning Japanese, she also started learning it herself. She learned the language fairly quickly, and is capable of having conversations in Japanese without the magic ring. She is shown to have a quite amount of strength as seen in her punches.
