Story

Persona: Trinity Soul takes place in 2020, approximately ten years after the end of Persona 3. It is set in Ayanagi City, a city located near the Sea of Japan, where the police force is investigating several "Reverse" cases, wherein the victims are turned inside-out. Ten years ago, Ayanagi City had been subjected to a sudden outbreak of Apathy Syndrome, which the city has since recovered from.

In the midst of the crisis, two brothers named Shin and Jun Kanzato move back to Ayanagi to see their elder brother Ryō, who is now the Superintendent of the Ayanagi City Police. It has been ten years since the three siblings last met with each other.

It was said that the mysterious incidents in Ayanagi City were linked to covert testing conducted under Keisuke Komatsubura's watch, which tried to locate all known Persona users and find the strongest by weeding them out via Persona experiments before it was disbanded.

Characters

Kanzato family

Age: 17

The seventeen-year-old protagonist. He is a second-year student at Naginomori Gakuen High School on the beginning of the anime, becomes a third year student during it. After his parents and little sister died, he and his brothers were under the care of their relatives in Tokyo, and ten years later they returned to their home town Ayanagi. Shin also has an interest in art, making clay models and is frequently seen sketching. Strangely, his art pieces resemble Personas and in one case, Igor. His birthday is January 19. His persona has the power to eliminate (cleanse) other personas with its sword. When he was seven years old his persona cleansed both his parents personas before they were completely extracted by Ayane, who almost caused both a reverse case and a fusion of both parents. Shin was deeply traumatized until he got hypnotized by Komatsubara to forget about that incident. [Persona]: Abel(アベル)

Age: 28

Shin and Jun's brother, eldest of the three at twenty-eight. His personality is stoic to the point of being cold, even towards his younger brothers. He entered the police in order to investigate the strange incidents, becoming the youngest superintendent in history. He keeps all important details on the recent 'Reverse' cases to himself, restricting them from others in the police force. His birthday is December 18. [Persona]: Cain(カイン)

Age: 14

The youngest of the Kanzato brothers. A second-year student at Naginomori Gakuen Middle School on the beginning of the anime, becomes a third-year student as the story progress. He began to lose the will to live after an incident that happened at the time their parents disappeared ten years before the series began. He had a twin sister, Yuki, whose dress he keeps. Oddly, Ryō overheard Jun seemingly speaking to a girl, presumably Yuki. This might indicate a spiritual body sharing, or multiple-personality disorder. He also has a certain level of perception ability and can hear the inner voices of people around him. He carries a pendant in the shape of a feather, which is a reminder of Yuki. During his visit to the beach, the water's reflection showed his twin sister summoning her Persona but not Jun. His fringe hides a scar on his forehead that came from the surgery involving him and Yuki. His birthday is February 4. It is told later that after the accident ten years ago, part of his brain was replaced with Yuki's, in an effort to prevent them both from dying (the decision was made by Ryō). His Persona is an accidental fusion of his and Yuki's. [Persona]: Seth(セト)

Age: deceased (would be 14)

The female twin of Jun. She died with her parents in a major accident ten years ago. She shares her Persona with Jun due to the fact that part of her brain was being used to replace his before her death. She sometimes takes control of Jun's body and had once been the sole inhabitant of their body after Jun's encounter with Ayane.

Mother of the Kanzato brothers. An artbook artist, she gave Yuki a 'Whale's Feather' as an amulet of happiness. She died in the Ayanagi City disaster when Ayane's Persona grabbed and nearly extracted her and Shigeru's personas, killing them.

Father of the Kanzato brothers. Like his wife, he was an artbook artist. He died alongside his wife Haruka when Ayane's Persona grabbed and nearly extracted his persona, killing him. It is revealed that they were involved in the same Persona research as Komatsubara.

Naginomori Gakuen

Age: 17

A classmate of Shin's who he becomes acquainted with him on the first day he attends school. He is an easy-going individual and sports a distinct afro. Surprisingly, he has a Persona, which awakens when Shin tries to do Shadow Extraction on him. Unfortunately, he showed very little ability in being able to control it, as it often flew off at random rather than fight when summoned (which became a recurring gag of sorts). Nonetheless, he does manage to master it by the end of the series. He also had a dream with Igor in it much like Shin did. He has a crush on Megumi. Takuro's father had disappeared during the Apathy Crisis in Ayanagi City, due to unknown reasons. Takuro stated that his father shoulder his friend's debts alone. He came back in a woman's body, although Takuro was unable to accept the possibility when meeting for the first time. [Persona]: Spartacus

Age: 17

A classmate of Shin's, though he actually saw her at a restaurant arguing with someone the night before he started school. She is a member of the Street Dance club and has a frank and straightforward character. She has a dislike for Shadow Extraction, and frequently scolds her friends for partaking in it. Megumi had her Persona awakened when she was still young during an accident after which her stepbrother died. Since then, she harbored a distrust towards it, believing it had chosen not to save her brother because of her inherent jealousy rather than not being fast enough. However, the growing crisis concerning Marebito eventually makes her recognize it as a protector, and she uses it for the rest of the series for the sake of her friends. [Persona]: Diana

Age: 17

A somewhat timid girl who is acquainted with Shin, Megumi, and Takurō. She is very interested in Shadow Extraction, and she asked Takurō to do a Shadow Extraction on her, which seems to be a forced invoking of a Persona to create a euphoria similar to taking a drug. She suffers from occasional memory loss where she sometimes cannot remember why she is at a place or even where she is at. In the past, she and Mayuri lived in a nursing facility. She becomes addicted to Shadow Extraction and this may have caused multiple personalities due to her sudden change in attitude and manner when talking to people, as well as suddenly saying things about what a Persona is without remembering what she said. She also demonstrates a romantic interest in Shin which is later confirmed by Yuki. She is eventually revealed to be a machine, much in the same nature as Aigis from Persona 3. Unfortunately, because of her artificial nature, her working lifespan is much shorter than a human's lifespan. After severing ties with Marebito, she peacefully dies in the company of Shin. Kanaru is unique in that she has the ability to invoke two Persona rather than the conventional one. However, the first one seen (Ashtoreth, in episode 20) proves to be the Persona of her "other personality" that is loyal to Marebito. She later invokes her own (Astarte) during a fierce fight between the Marebito and her friends, which briefly pacifies the battlefield in a stunning display of power. While most of the Persona in the series are humanoid, Kanaru's looks much simpler and resembles a jellyfish. Megumi comments that it is because Kanaru's is just a "baby Persona". Despite the death of its "master", her friends somehow manage to invoke this Persona one last time during the final battle. [Persona]: Ashtoreth/Astarte

Megumi's senior in the Street Dance club. She was under police protection during the period of the 'Reverse' incidents. During that time she was attacked by the Outsiders and almost had her Persona forcefully extracted. She was rescued, but suffered Post-traumatic stress disorder and was hospitalized. Her Persona is damaged from the extraction attempt.

Caretaker of the student dormitory. He keeps an old dog although pets are prohibited in the dorms. He had taken footage of Personas in action with his camera. He also knows a great deal about persona users saying that there were a lot of them around him many years ago. He also carries a gun in his jacket which he never uses. He might be Ken Amada from Persona 3 under an "alias".

A mysterious transfer student and a friend of Kanaru. She lived with Kanaru in a nursing facility in the past. Strange things started to happen after she transferred to Naginomori Gakuen High School. Her true identity is Saki Tachibana, a member of the Outsiders. Her favorite food seems to be beef bowls and she can quickly finish a big bowl in seconds; the feat contradicts her composed beauty image and greatly surprised Jun and Ryō.

Ayanagi Police

A medical examiner from the North Japan Medical Examiner's Office. Currently at the Ayanagi Police Station. She is also a longtime family friend of the Kanzato siblings. In the third episode, she visited Jun at Ryō's house and went to pick up Shin at the Ayanagi City hospital. Shin has a childhood crush on her even when she admits that she loves Ryō. She is currently investigating the case of the mysterious disappearances that occurred at Toyama Bay.

A sergeant and chief of the Ayanagi Criminal Affairs Department. He suspects Ryō to be hiding something about the recent "Reversed" cases before he decides to help investigate the true nature of the Apathy Syndrome crisis.

An investigator of the Ayanagi Criminal Affairs Department. He is a tall person nearing two metres. He works with Itō and is keeping watch on Ryō's actions before being sent to monitor Jun and the others from Naginomori Gakuen.

The vice chief of the Ayanagi Police Station.

Outsiders A group of Persona-users (possibly a non-natural type, medically induced) who seem to use their special abilities to steal other people's Personas. The group is called "Marebito" in Japanese and carries the meaning of a "foreign stranger" and "outsider."Illness and Culture in Contemporary Japan: An Anthropological View, By Emiko, Page 39. Retrieved on February 11, 2008.

A member of the Outsiders, he acts as the leader of the group. Tōma seems to be a cool and collected individual, but in the third episode he shows aggressive tendencies. He was killed in battle by Ryō, and afterwards an unknown chemical is discovered in his body. His death is kept in secret and was not publicised. However, there's some within his organization who claim that they have seen him walk about. [Persona]: Nebuzaradan

A member of the Outsiders, one of the executors of the Reverse incident. His Persona has the special ability to extract others' Personae, this ability is the cause of the 'Reverse' incidents. After being defeated by Shin's Persona, Yūji lost his Persona. He seems to be the most mentally unbalanced of the Outsiders and is often shown taking some kind of drug. He had a part-time job giving out balloons in a bear costume. Yūji is executed by Mariya after he went renegade by escaping from their compound. [Persona]: Utnapishtim
