Yuri Killian is a character from the Kaleido Star anime and is probably considered the main antagonist of the first season. Yuri is one of the best performers at Kaleido Stage and is partnered alongside Layla until Sora arrives on the scene. While he seems calm and suave on the outside, he harbors a secret hatred for his boss Kalos because of something happening in the past. Yuri, strangely enough, is one of the characters without being apart of or having a song sung with his voice actor. Yuri is voiced by Susumu Chibain in the Japanese version and by Illich Guardiola in the English version.
