Also known as: オキザリス(花騎士)
English Name: Lady's Sorrel
Artist: Kurot
She is Katabami's younger sister. A running joke between them is that Oxalis tends to call Katabami onii-chan (big brother) instead of onee-chan (big sister). Also, she dislikes being left behind, ironically since her name rhymes with okizari (left behind).
