Main protagonists

Lafiel is a strong-willed Abh princess. She is from the Clyuve Royal Family, in itself a member of the Abriel Imperial Family. As a granddaughter of the current Abh Empress Ramaj, she is in the line of succession to the throne. 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.

List of Seikai characters

Born Jinto Lin on planet Martine of the Hyde Star System, he is the son of Rock Lin, a politician who became president of the Hyde Star System. His mother was a mining engineer, who died in a mine accident soon after his birth. Because his father was busy with political activities, Jinto was brought up by his father's secretary, Teal Clint. When the Abh Empire invaded Hyde stellar system, his father surrendered the system in exchange for several concessions including selecting the territorial lord from amongst the people of Martine. As a result, Jinto rose to the ranks of Abh nobility along with his father. Growing up in a planet where he was considered the son of a traitor has not been easy for him. Even as he grew older, he would flinch at unfamiliar gestures. Jinto is eventually sent to the Planet Delktou to learn Baronh and Abh culture from Imperial citizens. Approximately seven years later, he leaves Delktou for a military college in Lakfakalle, the capital of the Abh Empire, to continue his education. It is in the spaceport of Delktou that he meets Lafiel who served as his escort and shuttle pilot from the spaceport to the patrolship Gosroth. The novels, and the anime, are a chronicle of the evolving personalities of the two, and their changing relationship with each other. He signs his name "Jint Linn".

Abh

Rock Lin

Jinto's father. His formal name in Baronh was Linn ssynec Rocr Dreuc Haïder Roch. He was the head of government of the Hyde stellar system (Haïdec in Baronh) during the invasion of the Abh Empire. Believing his own ideas more valuable than the rights of the people of Martine, Rock Lin decides to surrender the stellar system but stipulated that the territorial lord of Hyde should be chosen from amongst the people of Martine. The leader of the invading forces agreed to this however this meant that an election could not be held making Rock, as the current leader of Martine, the natural choice to become its territorial lord. Because of the size of his domain, he is accepted into the Abh aristocracy as a great lord and conferred with the princely rank of Dreuc, equivalent to Count. His actions were interpreted by the people of Martine as treason. After the Four Nations Alliance took the planet from the Abh Empire, he was executed by the Hyde parliament despite the best efforts of his old friend Teal Clint, the new President.
