Reigen Arataka

The agency started off as a one-man's agency, where Reigen himself would try to help people alone. Later Mob would come to the agency and seek help for how to control his psychic powers. After learning about Mob's abilities, Reigen hires Mob. Later in the story, other characters, such as Ritsu and Teruki, will eventually sometimes help Reigen when Mob isn't available. When Serizawa joins the agency and starts to get his life on track, he becomes Reigen's assistant and later be promoted to deputy director. At one point, Tome becomes the agency's secretary. The agency offers various psychic-related services, including exorcisms and seances. If an actual evil spirit requires exorcism, Reigen usually calls Mob to handle things, but for the other jobs, he can fake it until things work out.

Sometimes, clients visit for issues such as stiff shoulders and other back pains. These tend not to be spiritual at all, but Reigen keeps up his spiritual pretenses throughout these jobs as well.

Reigen’s Graphic Exorcism is one of his special techniques, which can easily handle evil spirits appearing in photographs. Due to the mutual dislike Reigen and Jodo have with each other, they are business rivals of the Rising Sun Spiritual Union. Dozen, another Rising Sun Spiritual Union member, also despises Reigen. 霊幻新隆, Reigen Arataka) is Mob's mentor and boss. He is the self-proclaimed "Greatest Psychic of the 21st Century" as well as owner and operator of the Spirits and Such Consultation Office (霊とか相談所, Reitoka Sōdanjo). He is the deuteragonist of the series. Reigen is a tall man with dark brown eyes and short, reddish-blond hair[3] with messy bangs. He is also very vibrant with his facial expressions ranging anywhere from attractive to terrifying, and he tends to sweat profusely.

He is usually shown wearing a dark grey business suit with a pink or black tie, though he has also worn such outfits as a sweatsuit, a tank top with shorts, and a complete high school girls' uniform. Still, that revealed that he also has relatively hairy legs. Reigen has few to no qualms about manipulating clients, enemies, allies, and even spirits to his own advantage. Later in the series, he feels guilty about manipulating Mob in particular. The gift of the gab or conversation is his specialty. Throughout the series, he has been shown to remain composed in almost any situation, and he is extremely reluctant to admit to his own mistakes. He is very careful during his investigations, and he often confuses his adversaries by announcing his next action aloud and then doing something different.

Reigen seems to be a man guided by principles and is very socially and emotionally intelligent. He believes hurting others is wrong and reminds Mob of that often, demonstrating his honorable and noble side covered by his shady business. When he entered the Claw headquarters, the subordinates found him to be a very kind and honorable man, and even after they realized he wasn't "The Boss", they still commented on his wise and caring nature. He is even willing to carry some of Mob's burden if it means the boy will suffer less, showing that he does care about those close to him, and even tells Mob he didn't have to stoop to their level and fight because he knows Mob would be hurting, showing he doesn't want Mob to feel pain. He is clever and agile, often taking action with his special techniques at critical moments.

He is also a very intelligent man, capable of analyzing a person's psychology fairly well and giving advice to several people, which makes them better individuals, such as the members of Claw. While he doesn't have supernatural powers, his keen intellect and ability to read people is so strong it can mimic, if not surpass real espers. Notably, he was the only one of the many espers who were assigned to eliminate the evil spirit possessing Minori Asagiri who didn't believe her lies. While the other espers believed it was simply the father attempting to control her and using the claims of an "evil spirit" as an excuse to justify his behavior, Reigen was able to notice things wrong with what Mogami said, such as switching from "papa" to "father", and calling Reigen a psychic despite not introducing himself beforehand. Because of this, Mogami abandoned his charade and attacked the espers.

Despite his status as a con artist, he often gives at least some sort of procedure or "spiritual cleansing" for whoever requests them. While his psychic powers are fake, he does take his job seriously and actually does, in fact, solve his clients problems. This is often done by simply listening to his clients and offering them a form of assurance and security. He also takes care to always solve his clients problems, offering refunds and refusing rewards if the job goes poorly. He does this both out of integrity and because failing to do this will only cause him issues such as his clients realizing he is a fraud. When one of his clients says some fortune teller told them spiritual negativity enveloped their shoulders, but only offered the words and didn't provide any actual service to the client, Reigen found it disgusting and stupid. Adding to that, his "spiritual cleansings" have been shown to relax his clients greatly, and many remarks on how they feel much better, demonstrating his abilities as an expert masseur.

He is shown to easily sense Mob's emotional state despite his student's stoic appearance and is quick to listen to Mob's problems and offer him advice. When Mob is training for a school marathon, Reigen immediately steps up to help him train, showing that despite his occasionally selfish tendencies, Reigen cares greatly about him even if there is nothing for him to gain. When he was publicly humiliated on TV and his career as a 'psychic' diminished, Reigen's biggest fear was being hated by Mob. But when Mob told Reigen that he considers him a nice person, Reigen felt relieved and happy that Mob doesn't hate him.

He finds all people to be equal, no matter what kind of abilities they have, and thus, he believes that those with psychic abilities who claim themselves to be "superior" are simply detached from the real world. Even when he gained phenomenal psychic abilities, he scoffed at them as no big deal.

His relationship with Mob has changed him, making him a better person. Reigen was about to quit his job and do something else, but at that time, he met Mob. Despite initially wanting to give him improvised advice so he could get rid of him, Reigen hired him as his personal assistant after witnessing Mob's psychic power. After a couple of years of working together, their relationship became close, with Mob looking up to him as a mentor, while Reigen sees Mob as someone he can actually help and support whenever he needs it. However, over the course of the story, Reigen becomes too dependent on Mob and doesn't want him to leave him behind, so he begins to summon him out of the blue, a thing that starts to anger Mob, causing him to abandon him eventually, something that affected Reigen more than he thought. But Reigen briefly demonstrated that he could actually manage his own business without the help of Mob. This proves that underneath his manipulative side, the reason why he felt he needed Mob is that Reigen sees him as the first friend he's had in his life and doesn't want to feel alone anymore, and feels proud of Mob because he was able to move on and have a private life. In contrast, Reigen's life is absolutely about his job, to the point of telling Mob in a press conference that he's grown up a lot. After these events, both reconciled and fixed their relationship. Reigen cares very much for Mob, to the point of taking a gun with him and standing in front of Toichiro Suzuki despite having no psychic powers, showing that he will put his life on the line to protect Mob. His grades were above average during his teenage years. One time when he was in grade school, he forgot to tell his parents that it was sports day at school, so he was the only one in his class with nothing to eat. He wrote an essay as a student expressing his desire to make a difference in the world; this was leaked to the media after his scandal on live television. He was a regular salaryman before quitting his job and starting his own business. One day, Mob encountered him seeking advice on controlling psychic powers. After discovering Mob's powers, he decides to hire the boy. Serizawa has curly dark-brown hair, messy eyebrows and eye bags, is quite tall and has broad shoulders and a handsome face. During his time at Claw, Serizawa had long hair with tight curls, a thin mustache, and stubble. He wore an orange hanten over a black long-sleeve shirt with grey sweatpants, and bright green crocs. He carried his white umbrella with him at all times. After the fall of Claw, he no longer carries his umbrella casually.

After being invited to work with Reigen and Mob at the agency, Reigen trims Serizawa's hair and shaves his face. When working at the agency, he wears a blue two-piece business suit. Serizawa was a withdrawn and naive person before leaving Claw. All of his trust was solely placed in Toichiro, looked up to him as a personal savior, and followed his orders without question. Before beginning his work at the Spirits and Such Consultation Office, if he were separated from his umbrella he would panic and completely lose control of his psychic power, which would cause heavy damage to his surroundings. He was haunted by a deep fear of his own power.

Serizawa's constant fear of losing control of his powers made him incredibly anxious. Due to his years under Toichiro Suzuki, he seems to have difficulty acting without guidance from others. However, after the fall of Claw, joining Reigen's agency, and starting to attend night school, Serizawa begins to come out of his shell and be more independent.

Serizawa is shown to care about others' well-being, even going as far as keeping himself in his room for the sake of others' safety. At present, he's more careful with his feelings and considers his thoughts more before giving advice or commentary. He's gained a little more confidence by working alongside Reigen and making friends with the people in his classes.

By the time of the REIGEN spin-off, Serizawa seems to be competent and quite confident. His personality growth is displayed when he shows off his powers for Tome and gives a lecture to help her become a psychic. Throughout his adolescence, Serizawa's powers often acted out on their own, leading to others becoming scared of him, scolding him, or rejecting him for the problems that they caused. The subsequent emotions only made his powers act out more. At age 12, after years of being bullied, rejected, and punished for the problems that his powers caused, Serizawa decided to retreat from society entirely, and locked himself in his room out of shame. Lacking guidance and companionship, not helped by the counselors his mother had hired, Serizawa remained in his bedroom for 15 years. His self-imposed confinement lasted until he met Toichiro, who offered to teach him how to use his powers, and gave him an umbrella to help calm his anxieties about leaving his room. Being offered the normalcy and acceptance that he desperately craved his entire life, Serizawa chose to follow Suzuki and join Claw.

With his lack of self-confidence, Serizawa was convinced that he could not achieve anything on his own, making Claw his chance to rejoin society, and espers his chance to be accepted and have friends. Serizawa became dependent on Suzuki, as he was scared to lose the small bits of normalcy, love, and acceptance that he had received, leading to Serizawa helping Claw achieve their goals. To further instill himself with a sense of normalcy, he would often refer to Claw as a company, with Suzuki as its president, and him his employee, often omitting the crime-related portion of his job entirely. He was aware of his actions and crimes, as well as Claw’s true purpose, but was able to delude himself of guilt with Suzuki’s encouragement and his own desperation for normalcy and companionship.

Serizawa is 30 and Reigen is 28. Reigen slowly falls in love with Serizawa and Serizawa is clueless
