She is a competent swordfighter, having learned the art of swordplay from her brother and later from Seth; however, she believes in looking for more diplomatic solutions before relying on strength. She has a very close friendship with both Princess Tana of Frelia and Prince Lyon of Grado. She wears the Lunar Brace, which is one of a pair of bracelets that together grant access to Renais's Sacred Stone.
