That cat like creature is Kastina's guardian. After an iccident when she was II she was stuck in a cave that was block by blouders. Her guardian, Jian, decided to break them away and take her as her own. Kastina calls her "mom". (She doesn't know who her real mother was at the time) Jian's actually a danlin, but she can shapeshift into a cat-like creature. #JianL #ITDU
