Lucy Watsuki - Ultimate Leader

I am primarily looking for someone with a mid-high vocal range who is also able to capture that self-conscious yet determined attitude she has. Someone who can put her foot down but doesn't like doing it. While I'm not looking for a direct impersonation, I did take heavy inspiration from Kaede Akamatsu and Erika Harlacher's portrayal of the character for reference. Here is her student profile for those interested:

Lucy Watsuki is a kind, supportive, trusting, and slightly dorky young woman, and she is the protagonist of the story. She is a studious girl, keeping her grades high while she helps around her town, and taking notes on her classmates at Mandela Academy. She never viewed her leadership skills as more than a common trait other girls her age have, so she struggles with finding the confidence in wholeheartedly admitting that she is the Ultimate Leader and is deserving of that title. She doesn't like upsetting others, and she can be very stubborn when she's trying to right a wrong she believes to have done. Her ability to push forward despite their circumstances has made quite a few of her classmates look up to her.
