Forte (Model Name NBC PC2198 AZ Forte) belongs to the same series of biocomputers like Mimi, but represents a newer generation. She has her master up completely and lives only to make him happy. Forte takes its task of protecting the system of government very seriously and considers this area as their territory, that they defended proudly and unyielding. Forte feels superior to Mimi because she is an AX system, while Forte is of the newer, more advanced AZ series. Even though they suffer may suffer in the beginning, she feels something like envy and also sympathy for her when she sees the self-sacrifice, that Akira and Mimi spend for each other, so that they can have what they finally want.
Supposedly born on Naboo, reliable records of Palpatine's past were hard to come by, but he somehow managed to become Naboo's representative in the Galactic Senate. His real identity was that of Darth Sidious, having been trained in the ways of the Sith by the Sith Lord Darth Plagueis. As he slowly rose through the ranks of intergalactic politics, Palpatine orchestrated the war between the CIS and the Republic, using various Sith apprentices as pawns, such as Darth Maul and Darth Tyranus. His master plan concluded with the scourge of the Jedi Order and proclaiming himself Emperor, and turning Anakin Skywalker into the Sith Lord Darth Vader.

Yuri, like Layla, is an experienced performer, yet he's deeply traumatized by a terrible tragedy. During a flashback, it is revealed that his father died attempting the Mystical Act, and he never forgave Kalos for letting his father try. 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. (wikipedia)
A smuggler owning the freighter Millenium Falcon, Han had dumped his cargo to escape from an Imperial cruiser during a smuggling run for Jabba the Hutt, causing Jabba to eventually put a bounty on his head. He agreed to help Luke and Obi Wan to rescue Leia Organa, and ended up working regularly for the Rebellion.
Fool is the mysterious spirit of the stage. He is about the size of an action figure, and appears as a type of jester or clown. He appears to Sora shortly before she appears on the Kaleido Stage for the first time. 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 from tarot cards, in the second season he reads and reveals the hidden workings of intercharacter relationships via astrology). He is also the one who explains the inner mechanics of the Mystical Act to Layla and Sora in episode 25, An Amazing Bond.
