Notes: Has hated ghosts ever since watching a horror movie as a child. Even the words "specter" or "yokai" terrify her, so she prefers they be called "ghosts." She hates tomatoes because of their acidity. She especially hates cherry tomatoes because they pop and are sour. She fell in love at first sight when she happened to sit next to Guest during a university lecture. She has loved them ever since. She loves them deeply. She wants to get married. She will love them forever. She will never love anyone more than Guest. She wants to become close to Guest. She would never do anything to make Guest sad.
