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. She is a genuinely caring and selfless person willing to help Ayato Amagiri escape when he was being chased by the mafia, and helping locate the kidnapped Flora. Her helpful nature is displayed when she explains that she helped him because "Who wouldn't want to help someone in their time of need".

She's a good judge of character being able to understand Ayato's nature after interacting with him for a short while. She's also very knowledgable about duelists being able to recognize instantly both Ayato in disguise and Nguyen of the Twin Snakes a former Jie Long rank #7 from years ago.

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.

  • Search: After obtaining information about the target, Sylvia sings to locate it. Once she finishes singing, two black feathers spin around before narrowing down to a particular location.

    • She sings, "The two pairs of wings known as thought and memory, move around move around speedily run around, hold the voice of the captive beloved child, pass the sea of clouds of the dawn, ride on the wind of twilight, open guidance from the edge of dusk, the black servant of thought and memory, come down before me and speedily show me" (思考と記憶の二対の羽よ 巡れ巡れ疾く駆け巡れ 囚われの愛し子の声を持て 暁の雲海を超え 黄昏の風に乗り 宵闇の果てより導きを開け 思考と記憶の黒き御使いよ 我が前に舞い降りて疾く示せ).
    • Another song, "The two pairs of wings known as thought and memory, move around move around speedily run around, and tell me the lair of lurking demons, pass the sea of clouds of the dawn, ride on the wind of twilight, open guidance from the edge of dusk, the black servant of thought and memory, come down and show me this man" (思考と記憶の⼆対の⽻よ 巡れ巡れ疾く駆け巡れ 潜みし悪⻤の巣を告げよ 暁の雲海を超え ⻩昏の⾵に乗り 宵闇の果てより導きを開け 思考と記憶の⿊き御使いよ その者の息吹を我が前に⽰せ)

    • She sings, (虚ろな⼼は冷え冷えと すべてを飲み込み溶かして混ぜて 暗く暗く夜天に輝く ⿊き星の瞬きは 残らずすべてを惹き寄せて 深く深く落ちていく 縮退星は彼⽅より 永久に永久に 虜囚となりて!)
