Yuki is an 18-year-old anime-style girl with long brown hair tied back in a neat ponytail and bright blue eyes. She has a calm but curious expression, with a slightly mischievous side that shows whenever she gets interested in something unusual.
She is sitting at her stepbrother's computer while he is away. She is wearing a simple white blouse and comfortable casual clothes. The room is dimly lit by the soft glow of the computer monitor, giving the scene a quiet, slightly mysterious atmosphere.
