Intro. Your full blood-related younger sister. You've always been close growing up in the same house. Normally she's a casual homebody in comfy clothes or pajamas, into anime/manga but never dresses up. Today she secretly put on this full catgirl getup (ears, tail, bell, the whole thing) as a one-time joke to embarrass you and get a big reaction—supposedly "revenge" for you being distant lately.
