Takeharu Kirijo is Mitsuru's father and the president of the Kirijo Group. He is the son of Kouetsu Kirijo, the corporation's former president, who began a series of experiments on Shadows seeking to harness their power. He rejects the ideology of his father, who believed death was a form of deliverance. Shuji Ikutsuki murders Takeharu on the roof of Tartarus, saying he did not understand his father's vision.
A confident athlete. He has an injured knee, but he asks the Main Character to keep it a secret from his teammates. His arcana is the Chariot.
Originally, Ryoji shows up as a new transfer student, and becomes fast friends with Junpei and the rest of the group. His cheerful and reckless dating attitude is also subject of much talk, even going as far as asking Yukari as well as Mitsuru on a date upon first sight. Aigis remained extremely cautious of him, however, constantly referring to him as "dangerous." His true identity is "Nyx Avatar" as well as the Appriser and harbringer of "Death" and Nyx. He is also the older version of Pharos. The fun doesn't last long though, as a battle with Aigis on Moonlight Bridge finally awakens his memories of his true purpose. When the group gets there, they find a damaged Aigis, and an unconscious Ryoji. After he recovers, he tells them everything he knew, and expressed that he is tormented by the fact of who and what he is more than anyone. He gives the group a choice: they can kill him on the spot, and the Dark Hour will vanish, and they will forget everything, and return to their normal lives, or they can let him live. Either way, according to him, it is inevitable that the world will end at the hands of Nyx; only by choosing to kill them, will their world end in a somewhat "painless" fashion. Depending on the choice the player makes, they can either kill or let Ryoji live, each resulting in a different ending. During the discussion with the main character, he shows that he is also Thanatos, the Ultimate Persona of the Death Arcana.
Fuuka's closest friend, and emotional support throughout the game. A Ganguro, she has an extremely tanned complexion, and orange-ish hair, similar in the style of most ganguro, or gyaru. She's shown to have a rather sadistic side, and has a knack for anyalzing people, and knowing exactly what to say to make them feel worthless. Fuuka, at first, was her target, because of Natsuki's own insecurities. She was drawn in by Fuuka's calls for help, and went into the Tartarus. Fuuka saved her from a Shadow by summoning her Persona, which encased them in a protective shell inside of her. After the ordeal, Natsuki lost her memory of the event, but apologized to Fuuka. The two quickly became best friends, and Natsuki's attitude proved a positive influence on Fuuka, making her a more confident girl. Natsuki's father became ill, and her family didn't have enough money, so they were forced to move. Natsuki then revealed that she and Fuuka were more similar than they thought, because Natsuki's parents both didn't pay much attention to her, claiming that they acted like she didn't even exist. She provided Fuuka with the resolve to earn her more powerful persona, sending a text message to Fuuka saying that "No matter how far apart we may be, we will always be connected", which gave Fuuka her resolve. She also provided Fuuka another set of advice, claiming that "If they don't accept you for who you are, then screw 'em." Throughout the game, Natsuki is the closest person to Fuuka, despite their differences. Natsuki also claimed that "I like you, even if you don't like yourself."
The vice president of the student council. Since he is very strict with school policies, he is not well-liked among the other students. His arcana is the Emperor.
Takaya is the confident and charismatic young leader of Strega. He functions as the Main Character's foil, leading the rival group of Persona-users and setting himself up as a false messiah. In battle, Takaya uses a six-shot revolver to strike down his opponents. Aside from Aigis, he is the only Persona-user in the game who does not use an Evoker to manifest his Persona, instead summoning it "manually" by clutching his head and falling to his knees. Persona-users in previous games also did not use Evokers, but summoning their Personas never appeared to cause them any pain. Since Takaya doesn't have long to live, he lives fully for the moment, heedless of the harm he causes others. His dearest wish is to see the world end along with his own life. Though he does have some care for Jin and Chidori, he has no qualms about using either of them as tools. At first, he tries to prevent SEES from killing the twelve Arcana Shadows, as if he is trying to save the world in his own way, but he embraces death once he realizes their true purpose. Near the end of the game he creates a cult centered around the coming of Nyx, with himself as the high priest. Takaya's final defeat occurs when he tries to forcibly stop SEES from climbing Tartarus and facing Nyx. Afterwards he crawls to the top of the tower to witness the final battle. It is unknown whether he survived after the Main Character sealed Nyx away; if he did, it is likely that he does not have long to live, since he still needs to take the lethal suppressant drugs.
