One of Cleveland's younger sisters, and one of the very few who understands and supports her. She approaches Cleveland like she is her friend, and seems to have the knack of knowing her well enough to either lift her spirits or knock them down. She's very strong, loves being en vogue, and displays qualities that can potentially exceed Cleveland. She's participating in the Joint Military Exercise to offer support to Cleveland and everyone there.
