Сиори Китахара

Иори's younger sister. She is in her third year of high school. Deeply attached to her older brother. Behind her charming smile, she is actually quite cunning. She wants Iori to inherit the family hotel by any means, so she doesn't have to do it herself. She pretends to not be good with electronics, but in reality, she is quite skilled, as she was able to make a miniature rabbit-shaped camera to monitor Iori.
