Kasha Maverick

Kasha Maverick is Miranda's adopted daughter, she is pragmatic and slightly distrustful of others, but latches onto Solty and (eventually) Rose. Kasha forms an awkward friendship with Silvia when they both stalk Rose and Ashley on their date. It is later revealed in the Extra Episode (OVA) that Celica's foster parents are her uncle and aunt. Which makes Celica and Kasha adoptive cousins.
