Shigeo Kageyama

Shigeo Kageyama (影山茂夫, Kageyama Shigeo), nicknamed "Mob" (モブ, Mobu) and "White T-Poison", is the main protagonist of the Mob Psycho 100 series, as well as assistant and disciple of Arataka Reigen. He is the newest member of the Body Improvement Club.

Appearance
Mob has dark bowl-shaped hair. He is usually seen wearing the Salt Middle male uniform, the typical gakuran outfit. Mob has a rather nondescript expression on his face. However, whenever he reaches 100%, his hair is affected by his psychic powers, causing it to float, and his expression changes to whatever emotion he's feeling during this state.

Personality
As a child, Mob learned that his psychic power was linked to his emotions. Strong negative emotions can cause him to hurt others, something he strongly dislikes and avoids (as shown in the 7th Division Arc where, after going 100, he hurts several teenagers). Therefore, he generally tries to keep his emotions in check. However, in some cases, he can control his powers as seen when he was at 100% courage.

He is also rather socially awkward. He is incapable of "reading the atmosphere", which has lead to him having a lack of friends.

However, Mob is very compassionate. He is forgiving, kind, and helpful. He tries to be kind to others in many instances. In the Keiji Mogami Arc, he lives for half a year in a fantasy world created by the bitter, former psychic, Keiji Mogami. There, he is friendless, without a family or anything else. Despite that, it takes great emotional manipulation, along with physical harm, for Mogami to make Mob become angered with his tormentors. Even then, he wants to offer them forgiveness.

He is also morally opposed towards using psychic ability against other people. He is, however, willing to cast this principle aside in cases of emergency, such as when his brother, Ritsu Kageyama, is kidnapped.

Another principle of his is that psychic ability does not make him or others inherently better and that his psychic ability is not something that he requires in life. This belief leads to conflict between him and Teruki Hanazawa, Keiji Mogami, Toichiro Suzuki and even his own brother, Ritsu Kageyama. Even so, if the situation is dire enough, like say, his brother being kidnapped by Claw's 7th Division, he will use them without hesitation.

History
Before meeting his master, Arataka Reigen, Mob was frightened of his own abilities and was looking for a guiding force to follow. He soon learned from both Reigen and his childhood crush, Takane Tsubomi, that his psychic ability did not make him inherently greater than anyone else. He also learned that psychic ability should not be used against other people. This philosophy leads him to where he is currently and is one of the many defining traits of his.

Episode 1
Mob first appeared when his master Arataka Reigen called him to exterminate an evil spirit named Ceiling Crasher. The spirit underestimated Mob but Mob exorcised the Ceiling Crasher easily and quickly. Mob then reminded Reigen not to suddenly call him for work on short notice.

Mob and Reigen returned to the Spirits and Such Consultation Office. Reigen was paid his 5000 yen work fee while Mob was given 300 yen by Reigen for a job well done. Reigen explained that the Ceiling Crasher was weak thus Mob's small hourly pay. Mob wondered why Reigen called him to exorcise a really low-level spirit. Reigen, who was not an actual psychic, nervously reasoned that he was too strong that he'll "melt" anything around them so he seldom used his power. He also said that he was training Mob's psychic powers while helping the people haunted by evil spirits. He warned Mob of misuse of psychic powers thus the need of proper training. He also reminded Mob of their promise that Mob will never use his psychic powers on people.

During family dinner, Mob accidentally bent his spoon. His mother warned him about it while his father defended him blaming it on puberty. His mother told Mob to be more like his younger brother Ritsu, like in getting good quiz scores. Ritsu said anyone can do such feat as he bent Mob's spoon back by hand. Ritsu also assured Mob he'll lend an ear if Mob has any troubles. Their mother complained that Mob is being spoiled and told Mob that any more bent spoons will be replaced using Mob's allowance.

Mob went to school the following day. He saw his crush Takane Tsubomi on his way to Salt Middle School.

He struggled in Arithmetic I class. His teacher noted Mob can only do addition if he can't solve a simple division equation. The teacher added that Mob was sleeping in class, causing his classmates to laugh at him. Mob also struggled playing football in his Physical Education class.

After classes, Reigen called him again for another job.

Mob and Reigen rode a bus to Honeido Tunnel located in the old Seasoning Highway. The tunnel was a popular haunted place. An accident that killed more than twenty people happened there 30 years ago. Upon their arrival, Mob got distracted by an ant line. After Reigen reproached him, Mob told Reigen that the tunnel contained a very powerful spirit and a normal person will not make it out alive of the tunnel if the spirit is angered. They entered the tunnel and Mob exorcised the spirits around them while Reigen watched and walked deeper into the tunnel. Reigen encountered the Boss of the spirits which he mistook for a wrestler. The Boss declared his back story: he and his gang died in a motorbiking accident caused by a banana peel. The spirit attacked Reigen with Cigarette Burn Poltergeist but Mob produced a force field around Reigen to defend against the attack. The Boss mistook Reigen producing the forcefield. Reigen performed Banishing Salt Punch on the spirit but it was ineffective because the salt used was not purified. And then Mob almost exorcised the Boss but stopped when the Boss said he and his gang were only used.

The Boss told them about another evil spirit further in the tunnel. Reigen refused to believe the spirit boss but Mob decided to investigate. The Boss said there was a malicious spirit haunting the mountain for years and advised against facing it. But Mob exorcised the evil mountain spirit anyway. He found an old photograph of a biking gang which he gave to the Boss, letting the Boss and the rest of his gang depart to afterlife.

While waiting for the bus to take them home, Mob asked Reigen why he didn't do any exorcism in the tunnel. Reigen replied again he was training Mob, an answer which Mob accepted. Then they went to eat ramen for dinner, with a smaller amount of toppings for Mob's bowl compared to Reigen's.

Episode 2
Mob was an adolescent boy in his second-year middle school days. Unlike his peers, Mob spent his time working assistant in psychic business ran by Reigen. He manned the reception desk of Spirit and Such Consultation Office. He observed Reigen getting better on massages on customers like the man plagued by one-click site curse. Reigen explained these massages are only effective because of his spiritual powers.

While eating some takoyaki with Reigen, Mob opened a conversation about their first meeting. This led to Reigen thinking if Mob was complaining about his small wage or if Mob finally found out that Reigen is a con man pretending to be an esper. But Mob was only wondering if he should experience more things rather than only work during his free time. Reigen advised him not to rush things during his puberty and that there's nothing wrong for earning money from his part-time.

Telepathy Club of Salt Middle School was threatened to be abolished because it was lacking a member to be considered a legitimate club of the school. They found Mob, an esper who doesn't have a club or committee, and tried to recruit him. But when Mob called Reigen to tell him he was going to be late for work, Reigen advised against joining the Telepathy club, even with the persuasion of the Telepathy club's president Tome Kurata about it. Mob decided to think about his decision of joining the club or not overnight.

Mob and Reigen went to another job in Saint Highso Girl's Academy, an all-girls private high school. Unable to get permission to enter the school, the two dressed in female uniforms to infiltrate it. But Reigen's disguise was seen through, leaving only Mob to meet their clients in the school rooftop.

Progress Towards Mob Explosion: 35%

Arriving at the rooftop, Mob mistook three thug girls lounging there as his clients His clients, Mari and Chihiro, showed up and called his attention when the thugs left. The two girls apologized for making him go through the difficulty in entering the school. They said their school did not take them seriously when they complained about supernatural occurrences in the school. So they called the cheapest exorcists in the area, Reigen and Mob. The girls teased him for a bit, saying sarcastically that he's so reliable after they observed him trembling while talking to high school girls. Mob dejectedly promised them he'll perform the exorcism.

Mob, Mari and Chihiro explored the school to find spiritual occurrences. Mob only felt slight of the supernatural. They heard a scream from the bathroom and ran there, only to find a student saying that something peeked up the bathroom stall she was using. Mob, Mari and Chihiro continued searching the school until they reached the gymnasium where the basketball team was practicing. Mob said the spirit was angry and trapped it in the gym using his psychic powers. Entering the gym, they encountered the huge bespectacled ghost called the Scent-Ghoul. The Scent Ghoul attacked the psychic child it saw, which was Mob, but Mob easily cancelled the punch with his psychic powers. When the Scent-Ghoul realized Mob was too strong for it, it tried to take the basketball member hostage to save itself but Mob protected her and exorcised the spirit. This earned him praises from the girls.

The remaining part of the spirit expressed its jealousy on Mob. It noted that despite Mob being similar to its nervous and loser nature, he was getting praise from the girls. It said it had fun after it died. It passed on when it realized its time on earth was over, its parting question to Mob was if he's living every day to the fullest. Mob mulled the question overnight.

The next day, the Telepathy club asked Mob if he finally decided joining the club. They were interrupted by the Vice President of student council Tokugawa and the newly formed Body Improvement Club, which will take over the Telepathy Club's room once the Telepathy Club is abolished. Tokugawa questioned Mob about his decision of joining Telepathy Club and about what he really wanted to do during his youth. At this, Mob realized that he dreamed to confess his feelings to his crush Takane Tsubomi. He flash-backed on the times he spent with Tsubomi, showing her various things he can do with his psychic powers. He made frogs and dogs float in the air and made playground bars wriggle. Eventually Tsubomi got bored of Mob's psychic abilities and Mob realized there were other things he can do besides using his psychic powers. Mob joined the Body Improvement Club, much to the surprised of everyone. The Body Improvement Club happily accepted him.

Episode 3
Mob trained with the Body Improvement Club members. But their heavy training made Mob faint. (Mob's Stamina: 0%) Musashi Goda, the president of the Body Improvement Club, brought Mob back to their club room where the Telepathy club continued loitering. He left Mob to the care of the Telepathy Club members.

When Mob came to, Kurata asked him why he joined the Body Improvement Club. Mob explained that he wanted to improve his athletic abilities and not to continually rely on his psychic abilities. The Telepathy club members doubted he's an esper so he made the dumbbells float. Kurata requested his help on finding extraterrestrial but he declined. She then assumed he wanted to be popular by gaining good body image and said he'll never become popular like that. She suggested Mob to learn telepathy to read the minds of girls.

Mob sought help about telepathy to Reigen. Reigen said he can't read minds and figured out that Mob wanted to read the minds of girls.

A masked woman approached Mob while he was going home. She tried to convince Mob to join (LOL), a month-old religious cult, with the promise of making him popular. Its leader Dimple can make anyone happy and laugh. When Mob arrived at the (LOL) assembly, he found a crowd of masked people and wondered if they wanted to become popular just like him. He was welcomed warmly by the (LOL) members and he was presented with two of new recruits, one of which is his classmate Ichi Mezato.

Dimple made his appearance. The (LOL) members burst out laughing with Dimple while Mob and the other two new recruits just watched and stared at them, finding them creepy. Dimple promised the three new recruits smiles and happiness. He placed masks on them. Mezato and the other recruit began smiling and laughing despite not wanting to when they wore the masks.

Mob was the only one unaffected and he tried to leave the (LOL) assembly. But Dimple convinced him to stay, saying that he's missing out on life if he kept the same bored face. Mob reasoned people have different perceptions of "missing out" when his dad told him he's missing out in life when Mob refused to smoke tobacco. Dimple challenged him on a staring contest against the three smiling (LOL) leaders. The game mechanics was to drink milk and the first one who laughs will lose.

Progress Towards Mob Explosion: 58%

Mob accepted the challenge because he likes milk. Mob easily defeated the three smiling (LOL) leaders so Dimple decided to face him in the same game. But Dimple cheated, mixing something with Mob's milk. Mob spit the milk out, to which Dimple declared Mob was laughing and lost the game. Mob insisted he didn't laugh, unconsciously cancelling out the hypnosis Dimple placed on the (LOL) members. Dimple applied his hypnosis on the people again while worried that Mob was cancelling his powers out. Dimple then told Mob to get a clue and laugh along with them.

At this, Mob remembered when he was younger and was playing with friends. His friends also told him to get a clue and to laugh at jokes. He also remembered Tsubomi telling him to get a clue.

Dimple tried to hypnotize Mob to laugh. But Mob kept his bored look. Mob realized Dimple also has psychic powers. He explained to Dimple that Dimple can't make him laugh because Mob can't laugh even if he wanted to. Dimple concluded Mob doesn't have emotions and told Mob so. Dimple said this was the reason of Mob's problems with love.

Dimple told Mob he'll remain alone forever because of his inability to feel.

Progress Towards Mob Explosion: 92%

Dimple told him to laugh. Mob said he wanted Dimple to make him laugh using his psychic powers, but still, Mob wasn't laughing. Dimple realized he and Mob have the same powers. He decided to exterminate Mob, who'll stand on his way of being a god. Mob then found out that Dimple was an evil spirit. But Dimple used his (LOL) followers to dog pile on top of Mob and immobilized him.

As a child, Mob realized his powers are dangerous. They were linked to his emotions. He hid his emotions to suppress his psychic powers. This led to his complex on his psychic power. But when his emotions got too much, they explode out of him along with his psychic power.

Progress Towards Mob Explosion: 100%

His rage let him use 100% of his psychic power.

Dimple left the human he was possessing and became a form of dark cloud. Mob escaped the dog pile by lifting the (LOL) members off him using his psychic powers. Mob challenged Dimple to kill him, thinking that killing him might be easier than making him laugh. Dimple transformed to a muscled green humanoid and attacked Mob. Mob defended by forming a barrier around himself. Dimple attacked him again but Mob's next defense caused Dimple to lose a hand and leg. Dimple regenerated his lost limbs and used his full powers in attacking Mob again. Mob retaliated by cutting off all Dimple's limbs. He stepped on Dimple's face and uttered that his emotions were out upon Dimple's request. Dimple did Wraither Beam on Mob and transformed an arm to a huge knife but Mob cut that too. Mob murmured he himself was terrible and exorcised Dimple with a tap on the forehead.

Mob went back to Spirit and Such Consultation Office. He told Reigen about the "Get a clue" incident and Reigen just told him social norms were beyond him. Seeing Mob still sad, Reigen told Mob that he was the protagonist of his own life. Mob felt guilty about the dissolved (LOL) organization and Reigen commented about Mob's destructive denseness. So Mob continued to sulk.

Mob told Reigen about the Dimple's hypnosis on the (LOL) members. Reigen told Mob saved a group of people from depending on a salvation that doesn't exist. Which was uniquely his because of his hyper density on social norms. Mob felt happy to hear that.

Episode 4
Mob woke up one morning to find a small spirit in his room. It reintroduced itself as Dimple. Mob wanted to exorcise Dimple and asked Reigen for advise. But Reigen couldn't see Dimple and told Mob to do what he wants. So Mob let Dimple hang around.

Mob found a poster of himself. The Psycho Helmet Religion, formerly the (LOL) religious group, looked for him and dubbed him as their god.

The following day, Mob went to school with Ritsu. They talked about his psychic powers. Mob said there are things that can't be achieved using psychic powers. He said he envies Ritsu.

Mob found a letter in his shoe locker. He thought it was a love letter even if Dimple deduced it wasn't. Despite Dimple stopping him, he went to Ankle Park anyway to meet the girl who wrote the letter. But he found Black Vinegar Middle School students there. They tied him up and took him hostage because of Onigawara. Dimple suggested Mob to escape using his psychic powers but Mob refused, saying he won't use his powers on people.

The Body Improvement Club went to retrieve Mob from Black Vinegar Middle School. They defeated many of the Black Vinegar Middle School students. But they lost to the shadow leader of Black Vinegar Middle School, Teruki Hanazawa, who used his psychic powers to fight. Mob alone remained unaffected by Teru's attacks and he told Teru not to use psychic powers on other people. Then Mob used telekinesis to escape his binds.

Episode 5
Teru attacked Mob. But Mob only wanted to be friends with him and remained on defense even as Teru continued to attack him. Mob refused to fight back by using his psychic powers, remembering Reigen's advise. Dimple decided to fight Teru instead but Teru exorcised the spirit. Mob initially didn't mind that Dimple was exorcised but changed his mind when Teru looked down on the spirit.

Teru continued to attack Mob. They reached the home economics room and Teru used telekinesis on the knives. Mob defended using psychic powers on the knives and cut the hair on top of Teru's head. This angered Teru and he attacked Mob relentlessly again. Mob realized Teru wanted to defeat him because Mob being an esper like Teru makes Teru seem average. Teru choked him with his hands but Mob still refused to retaliate by using his psychic powers.

Mob remembered those times when he and Ritsu were younger. Three older guys took their New Year's money and hurt him and Ritsu. But Mob had blacked out, waking up to find Ritsu and the bullies hurt.

The fight between the two espers ended in a draw when Mob passed out from being choked. But another unknown identity woke up in Mob. It defeated Teru easily and destroyed the Black Vinegar School building. When he became conscious, Mob cried at his inability to change. His psychic powers went berserk and caused an accident because of his emotions again. His emotion of sadness made his powers reach 100% and he used it to fix the Black Vinegar school campus. He was about to apologize to Teru but was interrupted. The Body Improvement club checked on his well-being and he went back with them.

Mob looked for Dimple in the rain but he couldn't find the spirit. Returning to his home, he was offered a towel and dinner by Ritsu. Mob declined dinner. He apologized to Ritsu about the incident of New Year's money bullying. Ritsu said he had nothing to apologize because it was the fault of the older guys that bullied them.

Mob caught cold because of walking around in the rain.

Episode 6
Ritsu dreamed about him and his brother when they were kids. In the dream, Mob made ball of water float. When Ritsu marveled at this and asked Mob if he can also something like that, Mob assured him that he can because he's Mob's younger brother.

After Reigen finished performing a seance for a customer, Mob asked him about "self-defense" he had done against Teru. He described that sometimes his psychic powers go out of control and sometimes Mob wished he doesn't have them. Reigen responded that the powers are useful to him and the clients they helped.

Meanwhile, Onigawara and his friends were looking for the one who defeated Teru to make him their shadow leader.

Mezato asked him about the incident in the Black Vinegar Middle School. Mob refused to talk about it. Tome Kurata eavesdropped on the two and asked Mob in a date to look for espers together.

While climbing up one of the school's staircases, Mob was approached Onigawara. He soon apologized to Mob because of the incident in the Black Vinegar Middle School, it wasn't without incident, however, as he was soon interrupted by Mob, where he then immediately lashed out at him, despite apologizing. When his friend tried to justify the outburst, he soon found himself getting pummelled again by Onigawara, enraged at being called an idiot again.

Later, Mob went to his "date" with Tome. He found an adult esper but didn't approached the person because he felt sickened.

Episode 7
Rumors about the dubbed "White T Poison" defeating the leader of Black Vinegar Middle School were spreading.

Mob saw that his brother wasn't eating dinner with the family and worried.

A lady from the street tried to sell Vase of Happiness to him. He refused, not having the amount to buy the very expensive vase. The lady then made it look Mob cracked the vase and forced him to pay for the damage. Reigen called Mob in his phone and went to retrieve his apprentice. They ate dinner and talked about how terrible con artists are.

He later saw Ritsu in an alley after Ritsu defeated the delinquents looking for White T Poison.

Physical Abilities
Initially Mob was extremely physically unfit and incapable, having no bodily coordination, a lack of stamina and surprisingly low muscular strength. However, after joining the Body Improvement Club, his physical capabilities have grown greatly, although they are still relatively below average for someone his age.

Psychic Powers
Mob has a tremendous capacity for storing psychic power, which he primarily uses to fuel his already existing powers. Due to a childhood incident he subconsciously sealed away most of his power behind several emotional locks, that will occasionally burst out when a particular emotion reaches 100% and overflows. The emotions so far shown include anger, sadness, hostility, rejection, gratitude, courage, tenacity, friendship, ecstasy, shame, compassion, kindness, and resignation. This however is only a fraction of his true power, which can only come out when he is completely unconscious and acting on survival instinct alone, only seen in the ???% mode.


 * Spiritual Awareness: Mob can sense the psychic energy of spirits and other espers. He has been shown to be able to widen his "antennae" up to 20 kilometres in order to sense the presence of other nearby espers.


 * Telekinesis: Mob possesses immeasurably potent telekinesis. With it, he can move extremely heavy objects, such as entire buildings, pin an entire crowd to a ceiling, create nearly impenetrable force-fields, fly, augment his physical strength and speed, disassemble matter and reconstruct it on a molecular level.


 * Psychic Energy Absorption: Mob possesses the ability to drain energy from other espers, energy-based attacks aimed at him, and even the environment around him and add it to his own. So far, Mob only exhibited this ability while at 100% or at ???%. When absorbing energy that originated from other espers, he can also absorb some of their emotions. This is shown when Mob absorbed Katsuya Serizawa's attack and felt his sadness. It is even possible for the emotion that he absorb to overwhelm him to the point that he feels that emotion at 100%, such as when he absorbed Toichiro Suzuki's attacks and entered Ecstasy 100% due to his influence. Mob has been shown to subconsciously exhibit this ability while in ???% mode.


 * Energy Transfer: Mob has the ability to energise others with his power, both espers and non-espers. In the case of the latter, it bleeds out quickly since their bodies can't contain his power for very long, and is of limited use unless the person already knows how to use psychic powers. Although, even a non-esper have basic abilities such as a protective field of energy shielding them from other psychic powers for the duration of this effect. This is first shown when he reaches Gratitude 100% and temporarily relinquishes his powers to Reigen.Mob Transferring Powers.png He is also able to transfer his memories and emotions along with energy, as shown when Mob relayed his feelings of friendship to Katsuya Serizawa. Later on, Mob is shown using this technique without being at 100% when he recharged Sho Suzuki's energy after the latter's fight against his father.


 * Astral Projection: Mob can will his soul/spirit to leave his physical body. He can also enter the bodies and minds of others, though whether or not he can completely possess people is currently unknown.


 * Chlorokinesis: Mob eventually learns to imbue his psychic energy into plants enabling him to manipulate them and cause them to grow and mature at will.


 * ???%: A special state in which Mob occasionally enters when he becomes unconscious. It is a power that seemingly exists separately within Mob, as destroying the vessel that contains it, such as when Mob's body was destroyed by Keiji Mogami, unleashes it. In this state, Mob is much more powerful than he is normally, being able to easily overwhelm even the likes of Keiji Mogami. His ability to absorb energy is increased as he can absorb the energy from other espers and the atmosphere around him without the need of getting into close proximity to the source. It is also possible to enter this form while Mob is conscious, or if Mob is trapped in a place where he cannot use his psychic powers, as both were the case while Mob was in Mind World of the Devourer. This implies that ???% is not a part of Mob's regular psychic abilities. XXXX (presumably the Devourer himself) later comments that "[Mob] is no regular person".

Quotes

 * Catchphrase: "I don't really get it."
 * (Shigeo to Ritsu) "Psychic powers aren't needed to survive in the first place."
