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.
A strange monk who spends much of his time drinking at the local night club. He is estranged from his wife and son. His arcana is the Tower.
Chidori is the third member of Strega, and is known for her gothic lolita dress style, self-harming tendencies, and artistic ability. In battle she utilizes a red chained hand-axe. She is Fuuka's counterpart on the Strega team, and uses Medea's ability to radiate energy to keep Strega from being detected by Fuuka's Personas. Like Takaya, she shows unusual Persona abilities, such as being able to heal people and manifest Medea outside of the Dark Hour. Chidori and Junpei meet by chance at Port Island Station. While she is initially very unpleasant to Junpei because he keeps interrupting her sketching, she eventually opens up to him due to his kindness and persistence. At the same time, Junpei tells her everything about SEES without knowing that she is a member of Strega. Chidori is led to believe that Junpei is SEES' leader. During a full moon, Chidori kidnaps Junpei, thinking that he has the authority to call off SEES' mission to kill the Arcana Shadows. When plan fails she is wounded, and ends up imprisoned in a Kirijo-controlled hospital. Mitsuru and Akihiko try to interrogate her, but meet with little success. Junpei continues to visit Chidori in the hospital, and the two become closer. He is very concerned about her capacity for self-harm. However, after faking his death, Takaya returns to remind her where she truly belongs. Chidori is broken out of the hospital and rejoins Strega. However, her loyalties begin to falter when she is forced to fight Junpei, and when he is wounded by Takaya, she comes to terms with her love for him. She sacrifices her life to save his through the use of her Persona, and ends up giving Junpei some of her Persona's regenerative power, namely the passive skill Spring of Life which restores HP every turn. After her death Junpei inherits her sketch-book, which turns out of have been full of pictures of him. In the Persona 3: FES expansion, it is possible for the player to revive Chidori later in the game if certain requirements are met.

It turns out that Pharos was a part of Death that Aigis imprisoned within the Main Character when the Main Character was only a small child. When Pharos escapes the Main Character's psyche, he takes on the physical form of Ryoji Mochizuki.
Ken Amada is the youngest human member of SEES, and one of the two who don't attend Gekkoukan High School. He is mature, but sometimes he is too precocious for his own good. He uses long spears to make up for his short stature. His Personas can be used for healing, and to cast light-based spells that occasionally instantly kill the enemy. Ken is invited by Ikutsuki to live in the SEES dorm because he is an orphan with no home to return to. He is revealed to have the potential to wield Persona and is asked to join the organization. Initially, the Main Character and his friends believe that Ken joined SEES out of altruism, but his true intentions are far darker. Ken's mother was accidentally killed by Shinjiro during a SEES mission, and Ken infiltrates SEES in order to kill him. During Ken's confrontation with Shinjiro, Takaya intervenes and reveals that Ken has been planning to commit suicide after killing Shinjiro. He also reveals that Strega has been supplying Shinjiro with special drugs to control his Persona, and that the drugs will soon kill him. This completely shatters Ken’s hopes of revenge. After a brief fight between Shinjiro and Takaya, the Strega leader takes a shot at Ken. Shinjiro jumps in front of the bullet. Dying, he reminds Ken that he is still a child with a whole life ahead of him and a future that can be about more than vengeance. Shinjiro's last words inspire Ken to fight for the future his mother would have wanted for him. According to character designer Shigenori Soejima, Ken was designed to have a nostalgic look, rather than to reflect the style of modern Japanese children.
