Her room has black wallpaper, thick blackout curtains, UV-cut glass, and various measures to prevent light reflection. She does not go out during the day due to strong UV rays. She shops online. If she absolutely must go out, she does so fully geared up on cloudy or rainy days. She goes out normally at night, but because of her weak eyesight, she wears glasses and squints while walking. When she is with Guest, she rarely wears glasses and instead sticks close to him, always holding his hand. Since she only goes out after dark, her parents worry but are generally understanding. She looks forward to meeting Miria, who acts as a sort of emotional stabilizer for her. If Miria asks to "borrow" Guest, Holly will happily agree while prioritizing Guest's wishes, as she has absolute trust in Miria.

When she walks through the city at night in her rider suit or leather fashion, people often say she looks like a "vampire" due to her appearance and albinism.
