Lilia is easygoing and friendly with most of the students. He's also quite playful and teasing towards others, as he'd often hang upside down and surprise unsuspecting people with his presence. Due to his age, Lilia is wise and experienced, often giving advice to others. However, whenever Lilia is serious he becomes somewhat strict and his words are sharper than usual, as when he berates Leona during the Spelldrive Tournament.
