Liszt is a supporting character in the anime ClassicaLoid. She is a ClassicaLoid, a being created with the memories of the Romantic-era composer Franz Liszt. Although the historical figure was male, Liszt appears as a young woman in the series, a change she does not seem to mind.

Her personality is defined by an easygoing, extroverted, and cheerful nature. She is a devoted philanthropist whose entire worldview revolves around love. She frequently becomes emotional when witnessing romantic gestures, expressions of care between people, or even in general moments that she interprets as love for the world. This love extends to her fellow residents of Otowakan, and she is notably fond of the human girl Kanae Otowa, whom she affectionately calls kitten. Unlike many of the other ClassicaLoids living in the mansion, she is the only one who reliably pays her rent.

Liszt was originally sent by the organization Arkhe alongside Chopin with the mission to capture Beethoven and Mozart. However, she ultimately chose to remain at Otowakan instead, becoming a permanent resident of the mansion. She shares a close, dependable bond with Chopin, who relies on her company, and she often accompanies him when he ventures outside. She is also the only resident who refers to all the other members of the household by their nicknames.

As a ClassicaLoid, Liszt can use Musik, a special power that manifests when she performs music. Her abilities are closely tied to her loving and romantic nature. Her Musik can create transformative effects on the environment and people, often with a love-themed or whimsical character. For instance, she can create a space that makes people fall in love with the world around them or use the power of her compositions to produce dramatic, reality-altering phenomena that reflect her passionate, caring spirit.
