Ann Takamaki is a playable character from Persona 5. She is a student at Shujin Academy who lives a double life as a Phantom Thief.
Ann is a second-year high schooler at Shujin Academy. Ann is the classmate of Akira in 2-D, and she and Ryuji Sakamoto were classmates in middle school. Due to her foreign blood and living abroad before the story, she does not have many friends there and is considered an outcast in Shujin. According to the artbook, her parents are away from home and she lives with "servants." Ann mentions she had a live-in caretaker, so these "servants" are likely caretakers. Both her parents are fashion designers who put on extragavant shows, and they jump from country to counry, so Ann does not see them that often. It is revealed that Ann also used to live in Finland.
Her only friend is Shiho Suzui. Ann met Shiho when she told Ann her painting sucked during art class. Despite this, as they were both outcasts, they became friends. Ann is being targeted by the volleyball coach Suguru Kamoshida who had a sexual interest towards her after he spotted her in a modeling magazine. Kamoshida constantly harasses her, threatening her that if Ann refuses to be with him, Shiho will be removed from the frontlines of his team.
Because of the coercion threats, she reluctantly makes appearances with Kamoshida in order to protect her friend, although she rejects any sexual advances Kamoshida makes. Vicious rumors then began to spread around the school that she was sleeping with him, further tarnishing her name around the school. Presumably because of her mistreatment at the school before Kamoshida became the volleyball coach of Shujin, worsened by Kamoshida's sexual harassment, Ann began to call Shujin a "sorry excuse of a school" and tried to convince herself that there was nothing wrong with her toxic coping regarding her predicament, as Shiho was her sole person of solace within the school.
Akira first meets Ann while both are waiting for the rain to stop before school. She is then picked up by Kamoshida, and reluctantly goes with him. Akira and Ryuji later talk to her to ask about Kamoshida, in attempt to expose his wrongdoings, but like other students, Ann is reluctant to talk out of fear that Kamoshida will kick Shiho out from being a regular in the volleyball team, but also because of bad rumors about Akira.
During the second infiltration in Kamoshida's Palace, a scantily-clad, cognitive copy of Ann, known as "Princess Ann," appears after the party defeats some Shadows with the help of Ryuji, who has awakened his Persona. Initially, Ryuji thought she was the real Ann, although Morgana, despite being seduced by her looks, points out she was a fake created from Kamoshida's cognition. The behavior of the cognitive copy is based on Kamoshida's distorted sexual desires towards her, not her actual self.
She later meets Akira again by coincidence, when Akira overhears her talking with Kamoshida on the phone. It was heavily implied that Kamoshida was asking Ann to go to bed with him, so she claims that she's not feeling well so she can't meet up with him which angered Kamoshida. After much persuasion, Ann finally reveals to Akira how Kamoshida is trying to force himself on her, as she finally expresses her frustration and disgust towards the teacher, refusing to do as he says. Feeling better, Ann's view of Akira changes, as she realizes how horrible rumors are when in reality it's not true, being the subject of them herself. Unbeknownst to her, Kamoshida sexually assaulted Shiho that day as revenge for Ann rejecting his advances.
The next day, Shiho attempts suicide by jumping off the school roof, although she survived the fall. Upon learning of it, Ann is shocked and saddened. Before she passed out, Shiho implies to Ann that Kamoshida has something to do with it. After an injured and comatose Shiho is hospitalized, Ann vows to seek the answers behind the reasons and get revenge for her friend. Overhearing that Akira and Ryuji want to expose Kamoshida's crimes, Ann asks to join them, but Ryuji harshly tells her not to get involved.
Not giving up, she secretly follows the two boys. As a result, she accidentally enters Kamoshida's Palace along with them. To keep Ann from danger, Akira, Ryuji and Morgana send her back to the real world. Unfortunately, the navigation app appears on her cellphone. Since she overheard Ryuji saying the necessary keywords to enter his Palace, she ends up returning soon after they sent her away. Kamoshida's knights find her, mistaking her for "the princess," and keep her in captivity inside the castle, which she believed to simply be a studio.
Later, the three find her on a torture device, surrounded by Kamoshida’s knights. Kamoshida is also there with "Princess Ann." The real Ann is almost thrown into despair when Kamoshida tells her that not only did he sexually assault Shiho, but that Ann is to blame for repeatedly rejecting his advances, "forcing" him to take out his frustrations on her only friend. With the help of Akira's motivating words, she finds the inner strength and determination to avenge her friend and all other victims, and utterly destroy Kamoshida for his heinous crimes. In doing so, she breaks free from the device and awakens to her Persona, Carmen, "killing" her cognitive copy and helping the party fight a Guard Captain Shadow that manifests as Belphegor. Since then, she joins Akira, Morgana and Ryuji to expose Kamoshida.
Despite being generally disgusted by Kamoshida's shadow and how she (as well as Shiho in Royal) was portrayed in his Palace, she and the party manage to defeat Kamoshida and take his treasure. After his defeat, Kamoshida pleads with Ann to kill him, but Ann refuses to, despite her hesitation to do so, since if he died, he would be unable to confess his crimes. Later on, Ann reveals that the decision wasn't out of mercy, but she wanted him to suffer as much as he lived.
In the real world, on May 2nd, Kamoshida tearfully condemns his own self and confesses to his crimes, being subsequently arrested and charged shortly thereafter, much to Ann's satisfaction and relief. Following his confession, her classmate Yuuki Mishima apologizes for not saying anything, despite knowing what happened. The two girls who spread rumors about Ann also apologize to her for their actions.
If the group fails to complete Kamoshida's Palace in time, it is never explained what happens to Ann, Ryuji or Mishima afterwards, but Kamoshida files charges against Akira and he is arrested for violating his probation. The scenario is a false recollection during Akira's interrogation due to the drugs he was administered by the police. Sae Niijima leaves the interrogation room to give Akira time to recover, at which point Goro Akechi takes the opportunity to assassinate him.
Ann is relieved to see Shiho recovering in the hospital and decides to stay a Phantom Thief so that she can save others from cruel fates that she and Shiho once suffered. While thinking of their next target, she is approached by Yusuke Kitagawa, an art student whom she initially thought to be a stalker until he clears the misunderstanding, telling her he wants her to be his next model for his art. After receiving request to steal Yusuke's teacher, Ichiryusai Madarame's heart for plagiarizing his students' artworks, Ann uses this opportunity to find out more about Madarame so they can enter his Palace and reveals to Yusuke that Madarame is not an honorable man he seems to be. She manages to do so by entering Madarame's studio where Madarame makes and keeps copies of "Sayuri" paintings to gain money, exposing him as a fraud. Before Madarame can call the police, Ann escapes with Yusuke and Morgana, accidentally taking the former with her into Madarame's Palace.
After their success in stealing Madarame's corrupt heart, Ann and her friends are approached by Makoto Niijima, the school's student council president. Having heard rumors that Makoto knew Kamoshida's true nature but, like everyone else, opted to stay out of it since she doesn't truly care about the students at the school, Ann begins to deeply resent her and is openly hostile towards her. Makoto then blackmails the Phantom Thieves to change the heart of mafia scam and blackmail artist Junya Kaneshiro, demanding them to prove their justice, or else she will reveal their identities as the Phantom Thieves to the police. After several days pass by Makoto asks how the group is doing with her assignment. Since they were having no luck entering the palace, a frustrated Ann states that Makoto is useless which prompts the student council president to act impulsively in an attempt to expose Kaneshiro. This results in a series of events that leads to Makoto's Persona awakening.
Ann later has a heart-to-heart talk with Makoto, where she learns she not only was deeply concerned about Kamoshida's actions and wanted to take action, she lacked the means to do so and thus felt very saddened and powerless all the while. The girls exchange apologies and also start to call each other by their first names, becoming friends in the process.
