Sylvia Lyyneheym (シルヴィア・リューネハイム) is the student council president of Queenvail Girls' Academy and the world's most famous idol.


Sylvia has long purple hair and purple eyes. She is breathtakingly beautiful. Despite her appearance, she is very strong, having won second place in the previous Lindwurm losing only to Orphelia.

Sylvia can use the headphone shaped hair accessory she wears to change her hair color. While in disguise, Sylvia has brown hair which she ties together. She hides her headphone shaped hair accessory under a hat.


Sylvia is bright and popular as she is the most famous idol in the world. She is playful around Ayato but understands how important her public appearance is.


Sylvia had a master, Ursula Svento, who taught her all she knows. After she went missing, she came to Asterisk to find her, and is currently trying to track her and Valda-Vaoth down.


Strega (魔女): Sylvia can use her singing to manipulate mana and control her surroundings, which makes her abilities as a Strega versatile as she isn't bound to a particular image. However, she has to write the song herself, she can't use any healing abilities, is limited to one ability per song, and her prana usage varies depending on what ability she is using, with her mentioning that using a time control ability similar to Helga's would instantly drain all of her prana.
