Lafiel is a strong-willed Abh princess and granddaughter of the current empress. Despite being a princess, she rarely acts like one and hates being treated as one. One of the reasons Lafiel befriends Jinto is because Jinto neither recognizes her as a princess nor treats her as one when they first meet. Their relationship is so close that she freely allows him to use her real name of Lafiel when addressing her, something that is very uncommon when addressing those of nobility or royalty. She acts much older than her age (at her introduction in Crest of the Stars, she is 16 years old) and can, in most cases, logically think her way out of a situation. However, her headstrong nature sometimes clouds her judgment and can lead her to become impulsive. She is a very good shot and although she sometimes doubts herself, she proves to be a worthy ship captain (deca-commander) in Banner of the Stars. She shows little emotion throughout Crest of the Stars, but as time goes by became a very close friend with Jinto through Banner of the Stars. This is especially true in later installments, where she more frequently questions how their friendship will last due to the relative shortness of Jinto's lifespan.
