Hanazawa Arc
Chapters 10 to 19

Synopsis
After losing to the Urabanchou of another middle school, Onigawara attempts to get the Body Improvement Club (which Mob has since joined) to help him fight him.

Onigawara orchestrates a plan in which Mob is captured by the opposing middle school and the Body Improvement Club comes to his rescue, thereby fighting the opposing Banchou. However, Teruki Hanazawa, known as the "Urabanchou", defeats the Body Improvement Club as well. He, unlike Mob, lives his life through his psychic powers and is disgusted at Mob's way of life. He tries to force Mob to use his psychic powers, and, in the process, hurts Mob and has the top of his head shaved off by a knife that Mob's barrier knocks away. Angered, Teru strangles Mob. Mob is knocked unconscious before going 100, and in this state he humiliates Teru, and destroys an entire school building before coming to his senses and putting in back together. This event is used by the Psycho Helmet Cult as material with which to worship their unknown leader, which is Mob.

Blackmail Arc
Chapters 20 to 33

Synopsis
After Mob's defeat of Teru, both he and his brother are approached by Ichi Mesato on the subject of Mob's psychic powers. Ritsu tells her very directly that all that Mob desires is a normal life and that he won't participate in any scheme she has planned. He also says that psychic power is the "base" of both his and Mob's life, despite the fact that Ritsu seems to have none. Mesato also reflects on the clear differences between Ritsu and and Mob, in their appearances, in their personality, and their popularity. Later, a meeting occurs in which the Student Council discusses a plan to clean up the school. Shinji Kamuro says the plan is to set up complaint boxes where students can complain about the behavior of others. Ritsu decides he supports it, to keep the school safe for his brother. Soon after, Tokugawa approaches RItsu, who is wandering about town, in a similar manner. He tells Ritsu that he should not try to imitate his brother and that he is his own, better, person.

Following this event, Ritsu is approached nearby his house by the creator of the Awakening Lab, who mistakes him for his brother. He is given a card and is told to visit the facility. Eventually, he does, and meets the rest of the Awakening Lab kids. They all seem exceedingly weak to Ritsu, who is used to the incredible power of Mob. Following his visit to the Awakening Lab, another student council meeting occurs. They discuss the exact details of the execution of the plan. Kamuro decides that Tokugawa stands out too much and that Ritsu would be a far better candidate for his plan. Although he is hesitant at first, Ritsu is coerced by Kamuro's words and eventually agrees. Later, Tokugawa and Kamuro are seen arguing over the new School Cleanup Plan. It seems Kamuro's initial plan is far different from the one he presented. Tokugawa tells him he won't support him and Kamuro threatens him with removal from the student council. After this, Ritsu learns of the plan as well, in which evidence will be planted that casts undesirable students as guilty. He is hesitant. Together, he and Kamuro remove the mouthpieces from the girls' recorders and plant the evidence in Onigawara's desk. Soon after school starts, the missing mouthpieces are noticed. As the girls in the class make a fuss over the new discovery, RItsu can be seen sweating and guilty. Afterwards, Musashi and Onigawara are seen running together. They head to school after finishing their run, where Onigawara enters his classroom. Only moments before, the girls' mouthpieces were discovered in Onigawara's desk, and Ritsu and the rest of the class look at Ritsu is disgust. Shocked, Onigawara attempts to defend himself. Kamuro taunts him, knowing that if Onigawara tries to hurt him, he will be expelled. Ritsu reveals recorder mouthpieces, planted in Onigawara's backpack. Onigawara, overcome by his classmates, flees in embarrassment.

After falsifying Onigawara's guilt, Ritsu discovers Dimple by the gate of his house. He is confused and so is Dimple, because Ritsu was never able to see spirits before. Dimple declares that Ritsu's psychic powers have been awakened. In Ritsu's room, he attempts to bend spoons as he has seen Mob do so many times. Frustrated that he can't and guilty over the earlier events, he bursts, yelling at Dimple that there is no way he now has powers. However, Dimple tells him to look back, and Ritsu discovers that his eruption of negative emotion caused the many spoons on his desk to bend. Excited by this discovery, Dimple tells him that if he can possess him, he will be able to help Ritsu refine his control of his psychic powers. He sees that Ritsu has an inferiority complex and decides to take advantage of that and his personality.

Keiji Mogami Arc
Chapters 59 to 67

Synopsis
One day after school, Mob is bullied by some high schoolers, but Dimple, Ritsu, and the Body Improvement Club step in to help him. Later Mob and Reigen go to do an exorcism for a rich man named Asagiri. Upon arriving, they see that he has hired many other psychics as well, including Shinrabanshoumaru and Lord Shoudou Kirin, leader of the Sun Psychic Union. Asagiri describes how his daughter, Minori is possessed by an evil spirit and he has been forced to lock her up. They do rock paper scissors to determine what order the psychics get to go in and see her in. Reigen wins by analyzing his opponents' hand movements to predict what they will do. Mob gets 49th out of 58. Reigen goes in and talks to Minori. It seems as though she is not possessed at all, making many of the psychics think that Asagiri is just abusing her, but Reigen notices inconsistencies in her conversation with him, causing the spirit to reveal itself. Dimple recognizes the spirit as Keiji Mogami, a former psychic.

While the psychics go in to exorcise the spirit, one by one, Dimple explains who Mogami was. Keiji Mogami was the first Japanese mainstream psychic. Mogami needed money to save his dying mother so he was forced to take on assignments that required him to lay curses on people to assassinate them. He almost killed Dimple when he was at the peak of his power. Mogami had started absorbing evil spirits so that when he died, he would be the most powerful evil spirit. He eventually committed suicide and became a spirit.

Eventually Mob realizes that Mogami is stronger than him and decides to cause himself to go into an out-of-body experience and go inside of Minori to chase the spirit out. He succeeds in leaving his body. Mogami goes to possess his body but Dimple is already in it. Mob is able to enter Minori's body while Mogami is distracted.

Mogami explains to Mob how they are in a mental world and he can bend it to his will. He demonstrates this by making Mob think he can damage him while there, before taking away his powers.

Mogami then says that psychic powers are fueled by emotions and that negative emotions are stronger. He then crafts the mental world into an exact copy of Mob's life except that he has no powers or friends. Minori also transfers into his class and she leads her classmates in constantly bullying Mob. The high schoolers that bullied Mob earlier also show up and Mob is powerless to stop any of this. Even Ritsu is a stranger in this world and he does nothing to help Mob.

Over the course of 30 minutes in the real world, Mob experiences 6 months in the mental world with all of his negative emotions building up. After an incident where Mob is powerless to save a stray cat from getting beat up by Minori and her friends, Mogami explains that after starting to take on jobs to put curses on people and getting enough money to put his mom in a better hospital, she still died anyways. As an evil spirit, she blamed him for it.

Dimple manages to use Mob's powers to open the door and let the other psychics go free, but he stays and decides to go into Minori's body and save Mob. Meanwhile, Mob is getting beat up my Minori and her friends one final time. Then, Mogami gives him his powers back. He immediately blasts everyone around him away. Minori starts crying and Mogami tells Mob to kill her. Dimple shows up but Mob doesn't remember him or anyone else from his real life, but Dimple is able to get him to start remembering, and Mob's imagination starts to be able to take control of the mental world.

Mogami continues to tell Mob to kill Minori, but Mob describes that this experience has taught him that people can change. Even if Minori really is as bad as Mogami made her out to be, she can get better.

Mogami then reveals that the people in this world are actually all of the spirits he absorbed. They morph into a massive, single being that grabs Mob. Mob then remembers that he's there to save people and reaches 100%. This instantly destroys all of the spirits and Mob unleashes the power of his courage on Mogami.

Mogami morphs into a giant mess of spirits that even he cannot control. It begins destroying Mob's body and Mob tells Dimple to leave. Mob fights the giant monster and reaches ???% and defeats Mogami.

Mob wakes up in his own body. Mogami leaves Minori's body and tries to possess Mob, but Matsuo from Scar, who was one of the psychics, captures him and renames him Pudding chan.

Minori wakes up and walks up to Mob. She could see everything that happened in her head and saw how Mogami portrayed her. Mob asks her if she actually acts like that and she says yes, then starts crying and apologizing over and over again. Mob says it's okay because now he sees that people can change.

Minori and her dad are in the hospital. Minori reveals that she's starting to forget everything that happened. They then find the website for the Psycho Helmet Cult.

Reigen refuses the massive reward that Asagiri was offering so he instead gives it to the Psycho Helmet Cult.

Separate Ways Arc
Chapters 68 to 73

Synopsis
As Mob is torn between his friends and his work as a disciple of Reigen, he finally realizes that Reigen is just using him for his Esper powers. As Mob and Reigen goes separate ways, Reigen also realizes, after a night at the bar, that he has no friends and that his life is kinda miserable. Even though Mob leaves him he reminds himself that he himself started this business and can go on without Mob's help. As he is by himself he starts to change. He begins to film the process of exorcising and uploads it to the net, gives free courses to prevent people to get tricked by frauds and gives people advice about their life. Reigen's reputation increases and he is soon known as "spice city's bro"

A few days later Reigen is interviewed by magazines and even offered to be on a television show. He gladly accepts as it can make him even more famous. However, the show is a set-up by Kirin Shoudou to exploit Reigen as a fraud. Shoudou seems to have a grudge since he discovered that Reigen punched him in the face while possessed by Mogami's spirit. The staff brings in a boy who is restrained to a wheel chair, supposedly possessed by a demon. Reigen attempts to exorcise the demon for at least half an hour, until Shoudou announces that it was all an act, a hoax set up by the studio. Reigen gets completely humiliated on the internet. Rumors about him being a fraudster increases and his old customers even creates a group of Reigen's victims.

Mob eventually hears the news but doesn't get worried. He believes it's all his Masters plan to get even more famous. Eventually, Reigen is hunted down by reporters and detectives hired by tv and magazines, and he is forced to explain himself at a pressconference. The night before the conference he tries to build up a plan to confront the media. Even so, he finds himself backed into the corner, he begins to mock the media and claim that they have no proof that he's not a psychic. After a while he gets the question of why he entered the supernatural business at all. Reigen thinks back three years to when he first met Mob, realizing that it was Mob's psychic powers that inspired him. Regretting that he has only used Mob he smiles at the camera and says "You have grown up" whereupon the whole conference building starts to shake and cameras begin to hover. The media is freaked out believing that this is Reigens doing and accuses him. Afterwards Reigen meets up with Mob and Dimple asking why they came. Mob answers that there was no particular reason, but Reigen still asks him if he now know his true identity, after what the media discovered. Mob simply answers that he knew Reigens true identity all along, that he was a "good person".

The arc ends with the psycho helmet club analysing the footage of the conference and sees the back of Mob's head and draws the conclusion that he's the "lord psycho helmet" and that he was behind the event.
