The official website describes Karen as "An enthusiastic Stage Girl who was captivated by the revue "Starlight" she saw as a young child. Although she's always in a good mood, she's not so good at early morning lessons. She participates in mysterious revues with Hikari, whom she's been friends with since a young age."

Karen falls under the role of the game's protagonist, and like many other protagonists is kind, bubbly and has a sunny disposition. She also can tend to be a bit clumsy and ditzy as well, and she cares deeply about her classmates, especially Hikari. However, Karen is slightly different than the traditional protagonist in the manner in that she does not act ignorant, she understands the cruel and competitive nature of the world she is in and chooses to act bright despite it. Her motivation comes from her ability and insistence on moving forward and overcoming the unfair odds of the world she is in, and this plays quite a bit into how she acts during more emotional scenes. 

Since Karen is the main role, and will get a lot of lines, we are hoping to find someone for the role who can portray Karen's emotional range. Karen's voice is also high mid-tone like many other characters of her archetype.
