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 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.
After the opening ceremonies, Ayato offered to buy drinks for everyone. On his way there he was stopped by Sylvia, causing him to mention that student council presidents had a hard schedule. She simply told him that it was work, noting that this time Xinglou herself came, telling him about the person she used as her substitute. Wondering why she was disguised, Ayato asked her about it, learning that Sylvia planned to investigate in the Entertainment District again after watching his match. He warned her about her frequent investigations, which she accepted. Sylvia told him about her theory that Ursula was being manipulated, both coming to the conclusion that it was probably the work of an Ogre Lux. Changing the topic, Sylvia gave Ayato a bento that she had promised him during the school festival. As he accepted it, she softly mentioned that she was nervous, but covered it up when he asked about what she said. She then mentioned that she needed to leave and left Ayato. Unbeknownst to them, Miluse and Tuulia had seen their meeting, high fiving each other on their find.
The day before his fifth match, Ayato called Sylvia to report his finding concerning the Eclipse arena. Additionally, he thanked her for the food while she told him she would be cheering both of them during tomorrow's match. She then canceled the call and headed to the place she was heading to, which was Petra Kivilehto's office. The door opened when she knocked and she was surprised to see that Rusalka were already there. Sylvia asked if she was lecturing them, to which she answered that it was half of their conversation, the other half was praise for advancing to the final eight. Sylvia noted their lecture to be because of their fight earlier. She thanked Rusalka for standing up for her but pointed out that as they had seen, Ayato wasn't someone that would try to trick her. When she warned them that Team Enfield would be strong, she caused them to get fired up. As they left, the members except for Rusalka declared they would win, while Mahulena apologized repeatedly for their behavior.
Once they left, Petra asked Sylvia not to fire them up as they were unstable due to Lyre-Poros' cost, though Sylvia believed that they were the same from before they received the Ogre Lux. Moving on, Petra asked her if she was serious about Ayato. Sylvia asked her what she would do if that was the case, prompting Petra to tell her that she would overlook her behavior to a certain degree. However, she warned Sylvia about her other matter, revealing the existence of an organization known as the Kinshihen Alliance. Despite knowing the name, Petra had no information on them, though did know that their name began to appear when Sylvia widened her search. Sylvia promised to tone down her searching to a degree and Petra agreed.
