Sylphiette is Rudeus' first friend of the same age. Rudeus saves her from bullies due to the fact that she is a mix of elf, human, and beast.
Displacement Incident/Mana Calamity Aftermath
She is teleported in the sky above a royal palace in Asura. Attempting to break her fall, she uses magic and ends up only with her legs broken. Immediately afterward, she sees a boar attacking the second princess of Asura Kingdom, Princess Ariel Anemoi Asura, during which she uses her strongest spell, saving the Princess and collapses to exhaustion.
Using up a massive amount of mana in a short period of time, her hair turns white as a result.
Due to her silent spellcasting, Princess Ariel took a liking to her and corners Sylphy into becoming her guardian, but only under the conditions that she pardons her crime of entering the palace without permission, and to help find her friends and family.
She is Rudeus' first wife and gives birth to their daughter Lucy and son Sieghardt. She is one of the three goddesses Rudeus worships in his religion. A cloth stained with her virgin blood that serves as a relic for the Goddess of Love is enshrined in the basement.
