Rai

In the game Code Geass: Lelouch of the Rebellion - Lost Colors, the player takes up the role of a mysterious young man who wandered in the Ashford Academy. Although this character can be christened at the player's discretion, the name Rai (ライ) is the default and canon option. The name seems to be derived on how the word "liar" is written in Japanese (ライアー).

Character Outline
Because his figure is rarely displayed, Rai's features remained a mystery for a long time. However, at several instances in the game he is described a quite handsome and possessing characteristic deep-blue eyes. On that note, accordingly to Rivalz, his good looks and the fact that he is never found no matter in which class people search for him earned him the moniker "Illusionary Adonis". It is also indicated that he has a slender build similar to Lelouch, albeit more athletic. Furthermore, a few CG pictures in the game reveal that he has a somewhat wild silver hair.

At a later point in time, support material for the game revealed Rai's design in its entirety.

Character History
Though there are differences in each scenario, Rai was once a prince born from the Britannian and Japanese royalty (the latter which is somewhat related to the Sumeragi house which Kaguya belongs to). But he, his mother and his younger sister were ill treated by the rest of the family due their status as "outsiders". So, in order to protect his mother and younger sister, he made a contract with a mysterious individual (hinted to be V.V.), acquired the power of Geass and used it to ascend to power after killing his father and half-brothers.

One day, Britannia was invaded by a neighbor country without warning. Outraged, Rai quickly ordered a full counteroffensive. Unfortunately, his Geass went out of control at that moment and caused all who heard him, including the civilians, to take up arms against the invaders. Although the enemy army was successfully repelled, there were massive casualties on Britannia's side, including Rai's mother and sister.

Overwhelmed by sadness, loneliness and guilt, Rai went as far as wish for his own death. However, the mysterious individual who gave him his Geass did not allowed that, saying that he still had to fulfill the contract they made. So he sealed Rai inside a Thought Elevator instead. At that occasion, Rai also used his own Geass on himself in order to forget everything that happened.

Decades later, Rai was found by General Bartley's team during their research in Kamine Island and then sent to the same Code-R facility where C.C. was. There, he was put through several kinds of experiments, including Knightmare training and artificial reinforcement of his body. He eventually managed to escape by using his Geass and shortly after found his way into the Ashford Academy.

When he was first discovered, Rai was in a weakened state and he had lost the memories of his past. This lead the President of the Student Council, Milly Ashford, to give him shelter. He was then allowed to spend his days on the academy as a provisionally enrolled student until his memories return.

Abilities
Rai possesses high situation-assessment abilities and commanding skills, along with physical abilities and Knightmare Frame piloting skills that go beyond that of normal individuals. In addition, he holds a mysterious power to manipulate others through hearing called Geass and changes the fate of many through its use.

Geass
Not much is certain about Rai's Geass. It is described as a "power of absolute obedience" just like Lelouch's, but that relies on sound propagation rather than visual information. It is visually represented in animated works as a expanding red globe, much like Rolo's Geass. For sure, only the three characteristics listed bellow are known:

 * It can affect all those who hear him, including himself. Of course, deaf people are immune;
 * Since this power is only conveyed by Rai's natural voice, it cannot be propagated through relays like speakers and tape recorders;
 * Effective range is limited to a distance in which Rai can be heard;

Knightmare Frame

 * Britannian Military Route: Lancelot Club
 * Order of the Black knight: Gekka Pre-Production Test Type
