A quaint and modern Japanese house at the eastern edge of Inaba, it is where the Yu stays for the year.

who also lives in house:
Ryotaro Dojima - A detective in Inaba. Yu's Uncle.
Nanako Dojima - A young preschooler. Ryotaro's daughter.

Dojima has short, grayish black hair, gray eyes, three-day stubble and broad shoulders. He is frequently seen wearing a dark gray shirt with pulled up sleeves, a loose, light red necktie and a brown belt with a metal buckle as well as a pair of dress pants along with dark brown shoes. On his left arm, he has a silver wristwatch. Despite carrying it around most of the time, Dojima is never seen wearing his black jacket.
Though Shigenori Soejima appear unfriendly as a means of conveying how distant he initially is to Nanako and the protagonist, he also focused on communicating both kindness and honesty.
Living alone with his daughter, Dojima is shown to be a hard-working detective, although he often becomes a workaholic. Adachi notes that he is a particularly harsh supervisor to him, but Dojima is a seasoned detective and takes his job seriously and is merely training Adachi for their line of work. While he loves his daughter, he has difficulty being a father to her, especially in wake of his wife's death, whom he states that Nanako resembles in both appearance and personality. His wife's death weighs on him heavily and he is obsessed with catching her killer, even at the expense of spending time with his daughter.
To the Yu, he acts as his guardian during his time in Inaba, yet states that he feels that the two share a bond more like brothers rather than uncle-nephew.
Dojima is the father of Nanako and the Yu's maternal uncle. Dojima works as a police detective in Yasoinaba, and is helped by his assistant Tohru Adachi. He lives at the Dojima Residence east of Inaba. Dojima met Yu in the past, but noted that he was still in diapers the last time he met him. Due to his older sister and her husband needing to work overseas for a year, he takes their son in for the time being and acts as his guardian during his time in Inaba.

A rural town in Japan and the central area in which the game takes place. It is where Yu moves to when his parents went to work overseas, leaving him in the care of his maternal uncle. Not long after settling into Inaba, strange murders began to happen that took the usually quiet town by storm.
Most of the town's younger population consider the town "boring" and in the "middle of nowhere", which is a theme of the game and a sentiment expressed by Yosuke Hanamura and Yukiko Amagi, although some are able to take pride in this aspect, finding it relaxing and peaceful. Inaba is surrounded by rolling hills, crops and riverbanks, and it tends to rain quite often.
This turns for the worst when the fog appears before December and persists for nearly a month, as it leaves them prone to even further exposure of rumors: in fact, one of it being poison convinces some they're sick, dividing people on their opinions on the matter, or even outright believing in flimsy opinions from the majority. They also lose touch with one-another as the fog blinds them from interacting on an even ground, especially surrounding the debate of whether the fog is truly poisonous or if it's just in people's heads. Lastly, people become comfortable with not being seen by others due to the fog, which makes them lax with being openly interested in rumors of the end of the world and people becoming monsters.

Okina City is the nearest big city to Inaba. It is connected to the town via Okina Station. Many students from Yasogami High School frequent the city due to shops and sights that aren't found back home.

The fog is a substance originating from the Midnight Channel. Like the normal fog found in the real world, the substance obscures vision of what it covers, making it hard to travel through the fog due to its thickness and tendency to cause fatigue. Only those wearing glasses are able to see through the fog and move normally.
The fog keeps the Shadows residing in the Midnight Channel from going berserk, unless a Persona User is nearby. Once a month, the fog lifts, causing the shadows to go berserk and try to kill any normal humans in the Midnight Channel.
The fog’s purpose is to blind people from the truth in order to let them live in blissful ignorance. Once Tohru Adachi is outed as the killer in December, the fog enters Inaba and remains there. People begin to embrace the fog and its remains, their behavior and beliefs shifting and becoming erratic. If nothing is done conderning Shadow Adachi in Magatsu Inaba, then the people of Inaba will become shadows near Christmas, killing the Investigation Team. Once Adachi is defeated, along with Ameno-sagiri, another being who spreads fog and utilizes it in order to cloud people’s judgement, the town returns to normal.

The Investigation Team is a group of Persona Users dedicated to investigating the phenomena of the Midnight Channel and stopping the murders in Yasoinaba in Persona 4. They work independently from the police due to believing that the police are inept and revealing the Midnight Channel to them could prevent the Investigation Team from entering the TV at Junes, potentially preventing them from ever catching the serial killer.

also sometimes stylized as Persona-user, is a being, usually human, who has the supernatural ability to summon their Persona. After they obtain their Personas their physical and mental abilities increase to superhuman levels. Some Persona users can summon multiple Personas with the Wild Card.
Yu and other Persona users crush their Tarot Cards to summon their Personas. When an ordinary Shadow gains an ego, it is able to become a Persona user.

Persona is a manifestation of a Persona user's personality in the Persona series, referred to as a "mask" for an individual to use to face hardship. Rather, the term "persona" is Latin for "mask."

A Persona is similar to a Shadow. Shadows are malevolent manifestations of one's inner thoughts, while a Persona is a manifestation of the same feelings but tamed and trained.

While the summoning sequence of a Persona differs from one installment to the next, a tradition that later adaptations follow is that blue-ish fire is always released when a Persona is invoked.

A fight using Personas weighs on the user's mind and spirit. Continuous use of a Persona will eventually drain the user's strength and stamina.
When one enters the Midnight Channel, one's innermost secrets that they actively try to suppress materialize and become a Shadow Self, which then attempts to force its host to accept it. If one cannot accept the Shadow Self, or if they refuse to acknowledge what they want to keep hidden most, the Shadow becomes enraged, attracting all nearby lesser Shadows to itself and transforming into a monster which attempts to kill the person it spawned from. If one can face oneself and admit to what the Shadow Self says, then the Shadow transforms into a Persona loyal to its user. During battle, one summons their Persona by manifesting their tarot card and breaking it, causing the Persona to emerge.

Yosuke Hanamura — Knives, Kunai user, Persona user. Yosuke has slightly unkempt fawn colored dyed hair parted in the middle and brown eyes. Yosuke is a clumsy transfer-student, who arrived six months before the At first Yosuke would be extremely considerate and cheery, but that would be a facade in his fear of being alone. Following his confrontation with his Shadow, Yosuke would become more honest with himself as to protect his friends: rather, he would normally come across as insensitive or an outright jerk and unintentionally insulting someone. One of his more common traits is poking fun.

Teddie — fights using claws, Persona user. After developing an ego, Teddie becomes a teenage boy with blond hair pulled to his left side, bright blue eyes and fair skin. He is shown wearing a white blouse-like shirt with various adornments like a red rose and a flamboyantly designed collar.Teddie is usually bubbly and cute and is known to lighten the mood when investigating the case, much like Chie. Possibly due to being a Shadow unfamiliar with the human world, or perhaps due to being a cartoon bear, Teddie has a lot of childish naivety, innocence and is pure of heart. He does not know a lot of human customs, does not know what "scoring a hot stud" means or what a "manwhore" is.

Naoto Shirogane — fights using Handgun, Persona user. Naoto is the shortest member of the Investigation Team. She is androgynous in appearance with short blue hair and gray eyes. Having lost both her parents in a car accident when she was very young, Naoto is an orphan who acts very mature in spite of her age.

Chie Satonaka tells the protagonist and Yosuke Hanamura about the popular urban legend of the Midnight Channel while they were eating at the Junes Food Court. Earlier, she also pointed out that she heard a student had seen the Midnight Channel, claiming that his soulmate was Yamano, the TV announcer. Knowing that it would rain pretty soon, they agreed to try it out and see if the legend is indeed true.
The protagonist stays up and stares at the TV in his room when the clock struck twelve. Without warning, blurred images of a female student appeared. When he touched the screen, his hand was sucked into it. Luckily, the TV he had was too small, and his body could not fit. He managed to pull his hand away, but accidentally fell and hit his head on the table in the process, and soon went to bed.
The Midnight Channel looks like a television studio, with large floodlights spread all over the place. The party discovers that Teddie is a resident in this world, along with innumerable Shadows. According to Teddie, the place a person is pushed into the TV World from the real world determines where they land in the Midnight Channel.
Victims who fall into the Midnight Channel do not attract Shadows unless the fog clears. When the fog clears, the shadows go berserk and will kill any humans trapped. Due to this, it is possible to kill victims by pushing them into the TV, but they can also be saved if they are rescued before the fog disappears. Victims who are killed in the Midnight Channel are expelled from the TV World and their corpse is found hanging from a telephone line with no physical indications of their death. If the person is too young or innocent to have a Shadow Self, its oppressive climate will instead put them into danger; even if they are saved, they will still fall critically ill due to the side effects caused by its climate.
When people appear on the Midnight Channel, it's because their recent mentions on television put them in the public interest.
