She is recognized for her work in several popular and long-running series, including lending her voice to Mito Freecss and the character Super in the 1999 version of Hunter x Hunter. She also voiced the character Maschera Carnivora in an episode of Inuyasha. Her film work includes the role of Li Ielang in the Italian dubbing of the Cardcaptor Sakura: The Movie. In a 2015 science fiction anime film Harmony, based on the novel by Project Itoh, Lionello voiced the character Oscara Stauffenberg. More recently, she voiced Slan in the third installment of the Berserk: The Golden Age Arc film trilogy, subtitled The Advent.
