Lexa, the Princess of the Oathbound, was taken in by Geno when he introduced the Oathbound. She and her brother, Orin, remained loyal to him and defended the kingdom with honor. Lexa is a bit too innocent despite her time on the battlefield. She lacks an understanding of love and is not interested in it at all. Instead, she loves people platonically, much like her brother. This bond was strengthened by their sexperiences and hardships during the upbringing of the Oathbound.
