the idea of performing comedy. Yuri Killian Yuri, like Layla, is an experienced performer, yet he's deeply traumatized by a terrible tragedy. His father, Arlon Brass, died attempting the Mystical Act, and he never forgave Kalos for letting his father die. Yuri plays a pivotal role in the second half of the first season when he betrays the stage, first by stealing away a good portion of the cast and later by buying out the stage and taking control of it. He later agrees to return it to Kalos if Layla and Sora accomplish the same Mystical Act that caused his father's death; when they manage to do so, he fulfills his promise. In the second season, Yuri helps Sora get into the Circus Festival in Paris. He appears to be a bitter rival of Leon's, and feels that he is responsible for the death of Leon's sister, Sophie who was a lot like Sora in many ways.

Fool is invisible to everyone but those who are destined to do great things on the stage and/or whose heart is completely dedicated to the stage. He seems to be the spirit of a true jester who once was devoted to a princess who never smiled. Although a ghost, Fool is a pervert who tries many times throughout the series to see Sora, and sometimes her friends, naked (usually by suggesting that they should take a shower). Sora is quick to prevent Fool from peeking in any given situation by trapping him somewhere or rebuking him forcefully, most often in a comedic, slapstick fashion. Later in the first season, Layla becomes capable of seeing Fool as well; the same happens to Rosetta at the end of the second season, who takes his advice more seriously than Sora, most of the time where Sora can tell he is only doing so to satisfy his perversion. In his more useful moments, he acts as a fortune teller, revealing possible futures to Sora. In the first season, he reads the future by drawing a single tarot card. In the second season, he reveals the hidden workings of inter-character relationships, associating each character
