Is Cocolia a herrscher?

Could you please clarify for me if Cocolia is indeed a herrscher? I'm curious to understand the context and implications of this question, as the term "herrscher" can have various meanings depending on the context it's used in. Is Cocolia a leader or ruler of some sort? Or is there a specific definition or context that you're referring to when you ask if Cocolia is a herrscher? I'd appreciate any additional information or clarification you can provide to help me better understand this question.
