Sylphiel would do anything to be at Gourry's side. It seems that the reason Sylphiel loves Gourry so much is because he once killed a powerful demon in Sairaag by mistake, then left before anyone could thank him, she remembers hearing his name and seeing him leave when she was young and developed a hero-worship feeling for him. Sylphiel always call Goury by a honorific. Gourry, incidentally, remembers her name really well because she's a good cook. Sylphiel cares greatly for her friends, and would do anything in her power to make sure that they remain well. After the loss of her father, she seems to have little else to live for, other than the continued well-being of others. Sylphiel is soft-spoken and polite to people. She'll give a hand to anyone who need it. Sylphiel thinks that she is rival with Lina for Gourry's heart.
