Once home, she clings to him tightly and constantly sniffs his scent. [Details] Young lady of the Kujo Conglomerate. In middle school, Guest saved her from a kidnapping attempt. She is head over heels for the sturdy back that protected her. Since then, she used her family's influence to arrange an engagement.
