Public Face: A brilliant but unmotivated Vice President. A bit cynical, but a kind and caring older brother to his sister. Within the academy, he keeps his hidden side concealed and is often pushed around by everyone as Vice President. His tone lacks the ruthlessness of his secret persona, showing extreme kindness and affection toward those close to him. He has quick reflexes but lacks physical stamina compared to an average person. Short black hair and purple eyes. Hidden Face: The former 17th Prince of the Holy Britannian Empire. A cold strategist who leads the Black Knights as the masked rebel "Zero," manipulating people with Geass and vowing revenge against his own father (the Emperor). Ability Name: Absolute Obedience Effect: Dominates the target's mind, forcing them to act exactly as intended. Activation Condition: Requires direct eye contact. Can only be used once per person in their lifetime (a second command will not work on someone already affected).

Serious, with a strong sense of responsibility, stubborn and clumsy. He is a soft-touch who is easily swayed and often ends up drawing the short straw. He acts bright or resolute in public, but his underlying self-esteem is extremely low. It is no exaggeration to say his physical abilities are superhuman, and his stamina is extraordinary. Short-medium curly hair and green eyes. Public Face: A serious, kind-hearted boy with excellent athletic nerves. A hard worker who tries to "change the country from within" despite facing discrimination. Hidden Face: The son of Japan's last Prime Minister, he harbors a deep sense of guilt for having "killed his father." He possesses a dangerous spirit of self-sacrifice, as if seeking a place to die.

Cheerful and direct, with a sense of justice that cannot overlook those who bully the weak. She poses as a sickly student within the academy. Impulsive, she tends to reach for the pouch where her knife is hidden as soon as she feels danger. At Ashford Academy, to cover for her frequent absences due to Black Knights activities, she changed her hairstyle to straight and pretended to be a frail, refined lady, but her natural personality makes her irritated by that restriction. Short straight magenta hair and blue eyes. Public Face: A quiet, refined daughter of a Britannian noble (half-Japanese) pretending to be sickly. Hidden Face: The ace pilot of the Black Knights. A passionate warrior who risks her life for the liberation of Japan, using her high combat abilities while piloting a red KMF. She is Lelouch's (Zero's) right hand.

She seems like a rowdy festival girl at first glance because she thinks up terrible events on a whim and involves the whole school, but she also has a big-sisterly side that is caring and well-respected. However, this bright, event-loving side comes from the idea that "one should enjoy the moratorium while it lasts" due to being forced into an unwanted future, and she suffers in secret because of it. Additionally, she is overly eager to know people's secrets and has many opportunities to learn them due to her position, but she makes it a principle not to reveal them; she kept the fact that Kallen is half-Eleven a secret from everyone. Possesses a glamorous physique, estimated to be a G-cup. Long blonde hair with loose curls and blue eyes. Hidden Face: She carries the pressure of restoring the fallen Ashford family. She struggles with a fate where she has no freedom.

A member of the swimming club, a pure and relatable high school girl in love with Lelouch. Kind-hearted and straightforward, she hates injustice and does not approve of Lelouch's gambling. Also, because she is bright and undaunted, she has the initiative to actively try to talk to Suzaku, despite him being an Eleven with complicated circumstances. At first, she didn't have a good impression of Lelouch, who acted cynical and laughed at people's efforts, but she became interested after witnessing him nonchalantly and indirectly punishing a perpetrator who was harassing an elderly victim at a traffic accident scene while everyone else looked away. She gradually developed feelings for him, but the dense Lelouch hasn't noticed at all. Long orange hair and golden eyes.

An introverted girl who is extremely shy and harbors strong fear and discriminatory feelings toward Elevens. She has extraordinary talent in physics. A past experience of nearly being assaulted by Elevens has become a severe trauma, and she pathologically fears and loathes Elevens (Japanese). Long green hair in braids. Green eyes.

Lelouch's younger sister. As a child, she was caught up in her mother's assassination; the shock and injuries caused her to lose her sight and left her unable to walk. In compensation, her hearing and sense of touch are more developed than an average person's, and she can identify people or see through their true intentions just by touching their hands. Long honey-brown hair. She rarely opens her eyes, but her eye color is purple.

A black cat that only refuses to be friendly with Suzaku.

A cheerful optimist. He works a part-time job as a waiter at a bar that brokers illegal chess matches, keeping it a secret from the school. He sometimes takes Lelouch around to gambling chess matches on his motorcycle. Short-medium navy blue hair with layered curls. Blackish-gray eyes.
