Other Espers
Joseph
Voiced by: Tasuku Hatanaka (Japanese), Ted Sroka (English) Foreign VAs
An Esper Mercenary hired by Claw during their push for world domination, actually a government-employed Esper hired to assassinate Touichirou. His specialty is White Noise, allowing him to control smoke.
- Big Good: He works for the government who's hired to track down and stop dangerous espers from wreaking havoc, such as Touichirou or ???%.
- Double Agent: He's introduced working for Claw as they prepare to take over the world, only to reveal that he works for the government and is plotting to stop the False King.
- Oh, Crap!: When Serizawa breaks through the solidified smoke barrier, Joseph (who had been progressively losing his cool as the Super 5 wiped out the mercenaries attacking Claw) goes wide-eyed in shock and freezes up.
- Super Smoke: His White Noise ability allows him to control smoke, to the point that he can make it as hard as steel to suffocate his enemies.
Fukuda
One of Shou's crew. An esper with the ability to heal wounds, and an overprotective attitude.
- Unwanted Assistance: Shou gets injured so rarely that Fukuda is afraid he might be seen as useless. To compensate, he follows Shou around and tries to heal extremely minor injuries like paper cuts and mosquito bites. The only thing he succeeds in doing, however, is pissing Shou off.
Ootsuki
One of Shou's crew. An esper who can control wind through inanimate objects. Currently uses a paper fan.
- Improbable Weapon User: While a paper fan seems to resonate with his powers the most, he also tried using a slipper, a newspaper, and a toy hammer before Shou saved him from making a fool of himself.
Evil Spirits
Ceiling Crasher
Voiced by: Takashi Onozuka (Japanese), Bill Rogers (English) Foreign VAs
A man who got scared by a roach and died from hitting his head on a ceiling. He became a ghost who haunts people's nightmares.
- Eek, a Mouse!!: Got so scared by a cockroach that he hit the ceiling and died.
- No-Sell: Absolutely immune to Reigen's vicious Splash Salt secret technique. Justified, as Reigen used regular old table salt instead of special purified salt designed for exorcisms.
- Starter Villain: The first villain/evil spirit to be introduced in the series.
- Underestimating Badassery: Is extremely incredulous that a middle-schooler like Mob would try to exorcise him. He regretted it pretty quickly.
- We Hardly Knew Ye: He doesn't get to do much before Mob exorcises him with a wave of his hand.
Boss
"Curse ya"
A biker who slipped on a banana and caught his entire gang into a deadly motorcycle accident. He and his biker stooges now haunt the Bone Well Tunnel.
- Bald of Evil: He has no hair and terrorizes everyone without a care.
- Banana Peel: The cause of his entire gang's deaths.
- Disc-One Final Boss: In the anime. He's the boss of the biker ghosts in Bone Well, but he's taking orders from a larger, much more dangerous spirit who's lived in the tunnel for ages.
- Playing with Fire: Has pyrokinetic attacks, symbolized with the motorcycle engine on his back.
- Sympathy for the Devil: In the anime. He was responsible for plenty of problems in Bone Well Tunnel, but Mob helps him and his gang move on peacefully after he ensures the memory of their days as human bikers will never die.
Kuchisake-Onna/The Dragger
"Are you thirsty?"
An entity born from collective belief in the urban legend of the same name, she manifests as a woman with a mouth sliced open along her whole jaw, who asks her victims if she's pretty before slicing them up with her scissors.
In the anime, she is changed to a woman who walks around, dragging several broken dolls on a string. Upon encountering someone, she asks them if they're thirsty before drowning them in the swamp. Her origin, however, remains the same.
- Absurdly Sharp Claws: In the anime, since she is changed to a different urban legend, she has no scissors but has extremely long, deadly sharp claws instead.
- Adaptation Deviation: She is changed to a completely different character in the anime, though her function (an entity born of collective belief, which can only be exorcised by someone who has no fear in her) remains the same.
- Blade Below the Shoulder: In the anime, the Dragger is able to shatter the dolls she drags around to enhance one of her arms and form a razor-sharp blade.
- Clap Your Hands If You Believe: The collective belief in her urban legend gave form to her.
- Creepy Doll: In the anime, she drags several large, partially shattered dolls on a string behind her.
- Emotion Eater: Because she is born from the belief of others, she adopts the characteristics attributed to her. Thus, being afraid of her makes her become more and more deserving of that fear, and thus more powerful. Anyone who sees her as an unstoppable threat cannot destroy her by any means, but Mob — who feels no fear in her presence — is able to obliterate her with little effort.
- One-Winged Angel: In the anime, she fuses with the entire swampland she haunts as her final stand, turning into a massive, monstrous water and mud elemental.
- Our Ghosts Are Different: Subverted. She is not a ghost or any sort of traditional evil spirit, but instead more of a collective tulpa.
- Shear Menace: In the manga, in keeping with the overall myth of the Kuchisake-Onna.
- Slasher Smile: Like the original myth.
- Stringy-Haired Ghost Girl: Appears as traditional onryō with either a mutilated (manga) or rotting (anime) face.
- Tulpa: She is effectively an unwillingly and collectively created thoughtform.
- Youkai: In the manga, she's inspired by the real-life myth of the Kuchisake-Onna. In the anime, her origins are different and she doesn't seem to be based on any particular youkai.
- Your Mind Makes It Real: She was born by the belief in her, and fearing her makes her even stronger. Mob being unaware of her legend allows him to exorcise her without incident.
Odor Sniffer
- The Peeping Tom: His modus operandi.
- Power Perversion Potential: Uses his techniques as an evil spirit to peep on girls in the bathroom and steal their personal items. He only reveals himself truly when Mob traps him in the school's gymnasium.
- Small Role, Big Impact: He's basically a spirit of the week, but his regrets of not living his youth to the fullest is what motivate Mob to join the Body Improvement Club over the Telepathy Club.
Wiggly Figure
- Dem Bones: Its main body is a skull buried in the soil of the farm.
- Green Thumb: Can control plants and roots.
- Henohenomoheji: The face on its scarecrow decoy.
- Small Role, Big Impact: A mere, one-time antagonist who helps Mob develop his own Green Thumb power.
Keiji Mogami (Spoilers)
Voiced by: Akira Ishida (Japanese), Sean Chiplock (English) Foreign VAs
A historically famous and extremely powerful Esper who became the strongest evil spirit upon committing suicide. He is encountered possessing a rich girl named Minori Asagiri.
- Affably Evil: Very soft-spoken and calm. He's genuinely like this and at most expresses mild surprise when something unexpected happens. Even in the face of utter defeat he simply delivers an analytical comment about it and escapes.
- Ambiguous Situation: It's not entirely clear what happens to him after he gets free in the World Domination Arc. However, he is most likely lurking out there somewhere considering that an Evil Spirit has to be at peace to pass on, something he certainly wasn't.
- Arc Villain: Of the aptly named Mogami Arc. Notable for having the longest personal screentime of any individual villain, even more than Suzuki, since The World Domination arc attention is diluted between the massive amount of characters present on it.
- Assassin Outclassin': After he stopped working as a hitman, he mentions many were sent to kill him. Keiji doesn't really expand on this... but he is shown walking away from a mountain of corpses.
- The Corrupter: Comes one step away from mentally breaking Mob by throwing him into an utterly hopeless world in an attempt to make him adopt his world view. He ultimately fails but only because of Dimple's intervention.
- Creepy Shadowed Undereyes: Constantly has these. He likes the look enough to actually manifest his spirit form with them.
- Curse: While he was alive laying these was his Signature Move as an esper.
- Defiant Captive: Despite being captured by Matsuo, he proves to be his most difficult and untamed spirit among his collection.
- Demonic Possession: Possesses a young rich girl in his first appearance. Attempts to pull this on Mob's vacant body when he uses the out of body technique, but Dimple fortunately takes the body first and protects it.
- Dissonant Serenity: He views people who pick on others as a plague on society and casually claims their lives have no worth when corrupting Mob.
- Dream Land: Capable of creating one inside the person he is possessing. He can shape it to his will and alter its fundamental rules, but his control over it wavers if the victims inside are strong enough to resist the Mind Rape
- Early-Bird Cameo: Only in the anime — he can be seen on the left side of the screen alongside multiple other psychics in the opening narration of the first episode.
- Eldritch Abomination: Powerful enough to qualify as this, and Dimple openly refers to him as the strongest evil spirit.
- Embarrassing Nickname: Like all spirits Matsuo captures, Mogami gets a sugary pet name — Pudding-chan.
- Energy Absorption: In life, he absorbed the power of Evil Spirits so that he'd become an exceptionally powerful one in death. When he's re-released during Claw's attempted coup, he decides to drain the energy from Claw's esper army as well. Mob later copies this style of ability during the final showdown with Claw's Boss.
- Famed In-Story: One of the world's most known psychics by virtue of being the first one to actually show the world the supernatural occurrences, psychic powers and paranormal events on television back when he was a teenager, and remaining as a TV celebrity until much later. He's equally famed in the spirit community for being the strongest and most dangerous evil spirit.
- A Form You Are Comfortable With: He likes to use the appearance he had as a 24-year-old, which he describes as his peak in human life. Somewhat unique in this since almost all evil spirits use outright monstrous forms or at least humanesque abominations, but Mogami likes his actual human visage and only starts to drop it when he is forced to use larger amounts of power.
- Freudian Excuse: When it became clear that people cared more about using his powers than they did helping him as a person, especially when his mother was dying of illness, he started becoming bitter towards all of humanity. His time spent as a hitman and the reveal that his mother's illness was a result of his powers drawing evil spirits towards her lead him to snap completely, and declare that powers like his and Mob's should only be used for their own gain.
- Green Thumb: Can possess plants to create large vine-like monsters.
- Humanoid Abomination: As an esper, he ate Evil Spirits for breakfast — in a much more literal sense than Mob.
- Karma Houdini: Briefly averted when he is captured by Matsuo, but then some Claw espers end up unwittingly unleashing him upon the world again. As of the World Domination Arc, this horrific monstrosity known as the most powerful and hateful evil spirit is somewhere out there, completely free to do whatever it wants - although it seems like his meeting with Mob may be the beginning of a Heel–Face Turn.
- Knight of Cerebus: The biggest of the entire series, massively outclassing Koyama or any other villain in this regard. His arc is by far the darkest in the series.
- "Instant Death" Radius: His life drains ability allows him to kill people around him. Even low-class espers get instantly killed by this. He comments that they are a nice meal.
- Mind Rape: He basically inflicts this upon Mob for a whopping six months. He comes dangerously close to breaking him and only fails due to Dimple's intervention.
- Nightmare Face: Produces a pretty horrifying one when it’s first discovered that Minori is in fact possessed. Notable for simply projecting the horror as a shadow behind her rather than wearing it himself. In the mind world, as he becomes damaged and forced to use more of his power his appearance deteriorates over time, giving a more monstrous look.
- Nightmare of Normality: He puts Mob into a mental image of his neighborhood - only without his powers - where he's constantly beat up by images of people who knows. Keiji's plan being to drive Mob over the Despair Event Horizon to get him to want to kill once he gives his powers back. It's only thanks to Dimple managing to break into the mental world and stop Mob that saves him from the brink and puts him back on focus to save the girl. What's more during all of this, while 30 minutes pass in the real world, to Mob in the mental one six months had gone by.
- The Power of Hate: He believes that the most troubled a person is and the more negative emotions they harbor the stronger the evil spirit they will produce upon death (if any). He's right and outright uses it as a part of his Thanatos Gambit.
- Professional Killer: Became one in an attempt to pay his mother's medical bills.
- Psychic Powers: He was an esper in life. Notable because he lacked the telekinesis that is signature to espers in the series. He still had the classic energy barrier and the ability to see and exorcise spirits though. His own "unique" power was to lay curses on others. These could even be lethal, which later allowed him to become a hitman. As a spirit, he manages to grasp telekinesis, but of a slightly different type than that of an actual esper.
- Psychological Torment Zone: Creates one inside of Minori's mind when Mob invades it, with the idea of turning him into a sympathizer of his twisted ideals.
- Satanic Archetype: Once among the most famous and powerful Espers, he eventually fell from grace and ended up becoming the most powerful evil spirit in existence. He is also in command of his own legion of the damned, composed of the thousands of evil spirits he absorbed. While inside Minori's body, Mogami tries to corrupt Mob into a self-centered Esper like himself or the Claw members.
- Sealed Evil in a Can: Eventually captured and named "Pudding-Chan" by Matsuo. He gets out much later during The World Domination Arc.
- Second-Person Narration: He serves as this to Mob’s first-person while he traps him in the Mind World. It’s almost pure nightmare fuel.
- Signature Move: The ability to lay curses was this for him while alive. As an evil spirit, he prefers a combination of Mind Rape and Energy Absorption.
- So Last Season: Averted. His brief appearance on the World Domination Arc shows that he is still as absolutely terrifying as last time. He effortlessly kills a large esper squadron and barely bats an eye as he overpowers a member of the Super 5... each of whom were more or less as strong as Teru.
- Thanatos Gambit: Step 1: Consume the essence of evil spirits. Step 2: Commit suicide. Step 3: Become an evil spirit too powerful to be exorcised.
- Villain Has a Point:
- Downplayed. He is not entirely wrong in saying that the world is fundamentally unfair, nor is he wrong in his assessment that, under different circumstances, Mob's life certainly could have gone down a much darker path. But ultimately, he's just horrifically petty and selfish — far from actually helping Mob like he claims to, all he's doing is artificially making Mob's life terrible just so he can gain a powerful follower.
- Played straight in his second appearance, he tells Mob that sometimes it's important to be hard on people when kindness won't change them. Mob would use this lesson when fighting against Touichirou.
- Villain Respect: In his second appearance, he spares Minegishi's life thanks to Mob vouching how it's important to have faith in people and their ability to change.
- Villain Takes an Interest: While dismissive of the rest of humanity, he sees enough of his past self in Mob that he decides he'd like to "save" Mob from his naivety and turn him into a sympathizer instead of disposing of him.
- Wake-Up Call Boss: The first opponent against whom Mob uses a completely positive 100%... as well as being the only one to actually overpower said 100%. Starting with him, major villains are now dramatically harder to defeat, always requiring more than simply going 100% and blasting said opponent to hell, basically because it's no longer enough.
- Weirdness Magnet: Deconstructed, it was this exact quality of his that caused his mother to become sick, with her becoming an evil spirit and yelling at him about this after she died.
- What Happened to the Mouse?: After he's released again during the World Domination Arc, he disappears with his fate being left unknown.
- World's Strongest Man: He's consistently referred as the strongest evil spirit and has the feats to live up to it.
- Yakuza: In order to raise money, he acted as a mob hitman.
- Year Inside, Hour Outside: When he trapped Mob inside the illusion world created by him, Mob experiences 6 months worth of school mockery while Reigen and Dimple have been watching him for 30 minutes.
Lord Psycho Helmet (Spoilers)
Originally a disguise taken by Dimple based off of a sketch made of Mob, Lord Psycho Helmet is, in reality, a sentience that had been developing inside the Divine Tree since the beginning of its existence, and was unleashed after Dimple relinquished control over its power.
- A God Am I: Initially serves as Dimple's puppet by boasting his potential godhood to others. Eventually, he'd develop a mind of his own and believe himself to be a true god.
- Arc Villain: Of the Divine Tree Arc.
- Botanical Abomination: How else do you describe a broccoli the size of a small mountain, born from an overwhelming release of psychic power and given sentience by the prayers of countless followers?
- Costume Copycat: He looks exactly like Mob only he's made of roots and has an uncanny valley appearance.
- Green Thumb: It can create roots and copies of itself made from the broccoli it was born from.
- Healing Factor: With the Divine Tree as his base, the Insidious Imposter can take on any attacks and regenerate itself with relative ease.
- Horror Hunger: Refers to Mob as nutrients in his first true appearance, and subsequently eats Dimple.
- Humanoid Abomination: It's an unnerving facsimile of Mob made out of broccoli roots.
- Hungry Menace: It may be a plant with divine powers, but at the end of the day, it's still a plant, a simple organism with simple desires. After Dimple releases his hold on it, its only motivation seems to be to eat. The bad news is that its nourishment now includes people.
- Mass Hypnosis: He manages to take all of Seasoning City under his control by tricking them into eating nutrients from the Divine Tree. And as he demonstrates to Teruki, he can use his natural energy to control them directly.
- The Starscream: Initially it was used by Dimple as a means of brainwashing the cityfolk. But after Dimple decides to give up his cult scheme, Lord Psycho Helmet decides to continue his work by taking over.
- Your Mind Makes It Real: Born from the belief of the Psycho Helmet cult, and only grew stronger the more people that Dimple brainwashed into joining the cult.
Sun Psychic Union
Banshomaru Shinra
Voiced by: Taiten Kusunoki (Japanese), Brock Powell (English) Foreign VAs
Even though I can't exorcise a flasher, I can still bring you to justice!
A psychic from a nearby city who is competing for the title of "rising star of the paranormal world" with Reigen. While initially antagonistic, the two become friends after being forced to work together on an assignment.
- Accidental Pervert: When questioning some girls about a flasher in a playground, his manner of questioning mixed with him grabbing hold of the girls made him come off as a creep.
- Acrofatic: Deconstructed. While he is more athletic than his size indicates, his stamina isn't very high. Even when he's possessed by Dimple, he still wasn't in good shape.
- The Cameo: He appears in the Reigen manga spin-off where he gives Tome's high school teacher an amulet to protect him from a spirit.
- Dude in Distress: He's tasered and rendered unconscious by the red-coated flasher and would have been at the mercy of the Dragger if Dimple hadn't shown up to possess him.
- Empowered Badass Normal: While still no Esper, he actually is more of a psychic than Reigen thanks to his blessed necklaces, which can entangle evil spirits. Taken even further when Dimple uses him as a host, giving him true Esper powers for the duration of the possession.
- Fantastically Indifferent: While Touichirou is monologuing on TV, announcing Claw's goal to level Japan, in contrast to Shoudou, Banshomaru continues watching and eating dinner unfazed.
- Heel–Face Turn: Happens almost instantly. He goes from minor "antagonist" (word used lightly here) out to steal Reigen's assignment to a friendly rival of Reigen after Mob saves both of them from a Yokai.
- Hidden Depths: When he was in high school, he was part of the sumo wrestling team but later joined the table top tennis club.
- Iconic Item: His over-sized beaded necklace.
- Not-So-Phony Psychic: While Reigen initially assumes he's as much of a fraud as himself, it turns out he does have some ability in exorcism.
- Overshadowed by Awesome: Quite skilled at his job, reasonably knowledgeable about magical phenomena, some nice magical items, is generally competent in a crisis... and his psychic abilities aren't even as strong as most of the more mundane psychics, let alone people like Mob.
- Token Good Teammate: Compared to the vengeful Kirin and the arrogant Dozen, Banshomaru stands out as the only amicable member of the Sun Psychic Union.
Kirin Shoudou
Voiced by: Teruyuki Tanzawa (Japanese), Jason Marnocha (English) Foreign VAs
I'd like to see Reigen's ability. Even if I try hard, it's not spectacular at all. We should let the whole nation witness how the next generation of psychics does it.
A decrepit old man and the most senior psychic in the business, both literally and figuratively. He has formed the Sun Psychic Union as a way of both maximizing profits and maximizing his control over the business. Something of a TV star, he is one of the better-known psychics in the business. His actual abilities are unknown, though he appeared to display an unusual aura while performing an exorcism, hinting he may be an Esper.
- Arc Villain: Takes Reigen's mantle as the main antagonist during second half of the Separate Ways Arc.
- Disproportionate Retribution: He had Reigen exposed as a fraud just for getting knee'd in the stomach by him, even though it was to undo Mogami's possession (and defend himself).
- Dude in Distress: He's instantly possessed by Mogami and is used to attack the other psychics.
- Evil Old Folks: He shames and humiliates anyone who dares to go freelance, and even tried to do so to Reigen even though his only interaction with the fox man was the latter saving his life. And of course he's so old he would die if he was told to act his age.
- Fake Ultimate Hero: He's supposedly the strongest esper in the Sun Psychic Union, but he's unable to fight or defend himself against a dangerous spirit like Mogami nor do anything but cower when Touichirou rolls around trying to take over Japan with his organization.
- Gonk: His pudgy face is permanently stuck in a bizarre, wide-eyed grimace. He actually manages to unsettle Mob.
- Jerkass: He will try to ruin the lives of any psychics who try to go freelance, despite the fact they usually pose no threat to him.
- No Good Deed Goes Unpunished: He got a good look at Reigen's face during the Minori Asagiri exorcism when Reigen saved his life. His repayment was to try to ruin Reigen's life for going freelance (and for hitting him to drive Mogami out of him).
- Oh, Crap!: He gets two of these moments.
- The first time is when he's watching Reigen's public conference and is flabbergasted when the room suddenly shakes and many of the objects in it starts to float out of control; he was terrified at the possibility of Reigen having actual powers.
- The second time is when Touichirou broadcasts his declaration of world domination. The tomb-hopping relic can only cower in fear due to the foreboding presence of the tyrant king.
- Suspiciously Similar Substitute: He brings to mind Ishiguro given how they're both short, old psychic men who dress in black and have self-absorbed personalities.
Dozen Roshuto
The self-proclaimed "strongest psychic of the solar system". He appears in the Reigen spinoff and becomes the titular psychic's rival.
- Dirty Coward: After being cursed during an exorcism mission, he initially planned to pass the curse onto Reigen. But to his relief, he ends up passing it to Tome and doesn't feel much regret over it.
- Evil Counterpart: To Reigen. He's a suit wearing psychic with a fancy title, has his own apprentice and tends to use exaggerated expressions. (He even looks like Reigen with black hair). The differences are that he doesn't have Reigen's good heart and is willing to brush off his apprentice for the sake of business matters.
- Karma Houdini: He faces no consequences for trying to pass a dangerous curse to Tome and later Reigen. The heroes don't even mind that he still shows up in their office the day after.
- Know-Nothing Know-It-All: Despite claiming to be a powerful psychic, he instantly falls for Reigen's lies about spiritual power levels.
- Powerful and Helpless: He proclaims to be a high ranking psychic with connections to influential figures and celebrities. Neither his powers or connections are able to help him when he finds himself cursed.
- The Rival: To Reigen, much to his annoyance.
Other Characters
Minori Asagiri
Voiced by: Mao Ichimichi (Japanese), Kayli Mills (English) Foreign VAs
A rich girl possessed by the ghost of a powerful Esper. Her father calls Spirits and Such to exorcise her.
- Adaptational Nice Guy: A downplayed example, as she remains the Alpha Bitch bully who relentlessly tormented Mob for six months to elevate her social position. However, the anime still excised some of her more cruel actions toward Mob, painting her as a more typical school bully rather than the borderline sociopathic one she was in the manga.
- Alpha Bitch: The most popular girl at her school, she bullies the weaker, less popular kids to remain on top.
- The Atoner: After going through a My God, What Have I Done? moment, she resolves to stop her bullying ways and become a better person.
- Creepy Child: As Mogami's host, she speaks in a chillingly calm voice and gives a creepy Thousand-Yard Stare. She's not much more pleasant without being possessed either.
- Demonic Possession: By Mogami.
- My God, What Have I Done?: When she sees how she's perceived through Mob's time in Mogami's private world, her first act upon awakening is to tearfully beg Mob for forgiveness as she resolves to be a better person.
- Not Brainwashed: Despite being one of Mogami's victims, she willingly bullies and terrorizes Mob while he's held prisoner in Mogami's Nightmare World. Even after they wake up, Minori confirms that she's always been like that.
- Powers via Possession: Mogami's possession seemingly enhances her strength, as besides channelling his telekinesis, she's strong enough to hurl a grown man into the ceiling and beat up a group of professional exorcists with some wicked martial arts moves.
- Rich Bitch: Her normal personality. It continues into her fantasy world, where she belittles and mocks Mob.
- Single Woman Seeks Good Man: She appears to develop a crush on Mob and desires to see him again after he saves her from Mogami, forgives her for her actions and her father reveals to her that Mob didn't demand any reward.
Mrs. Suzuki (Spoilers)
Mrs. Suzuki
Voiced by: Houko Kuwashima (Japanese), Erica Lindbeck (English)
A compassionate woman who was once married to Touichirou before he began his conquest for world domination and is also Shou's mother.
- Good Parents: She genuinely loves her son and hoped that he would grow up to be a gentle boy. Even in the present, Shou confirms that he regularly sees her even while dealing with his dad's nefarious schemes.
- Kindhearted Cat Lover: Her very first scene has her tending to a stray cat, showcasing her love for others.
- Morality Pet: Double subverted. Despite being married to her, Touichirou still planned out his dream of world domination regardless of what she thought or who he would exploit along the way. But it isn't until he realizes his mistake of driving her away along with Mob giving him a second chance to reconcile with her does he start to take baby steps in letting go of his old ways.
- Screw This, I'm Outta Here: Realizing that her husband only sees people as inferior beings to manipulate and abuse, she decides to cut ties with him.
- Small Role, Big Impact: She only has one scene in the entire series but it's through her leaving Touichirou do we see a glimpse of his humanity and how he too longed for connections with other people.
- Turn Out Like His Father: In an Omake, Shou dreamed of a time when he used his psychic powers only for his mother to break down in tears.
- Useless Bystander Parent: Played With. On one hand, she had zero involvement in keeping her son safe from intermingling with his father's sinister plots nor did she try to protect him when he directly confronted him. That said, there's no mention of her having esper abilities to offer any support so she could have become a casualty with her involvement. It can also be inferred that Shou wouldn't want his mother to be hurt while battling his father.
- What Does She See in Him?: It's anyone's guess as to how she fell in love with an arrogant madman with a god complex. But whatever it was, it didn't last when she realized his true colors.
The Aliens
The Aliens
A group of aliens that reveal themselves to Mob, Reigen, and the Telepathy Club after the latter attempt to contact extraterrestrials.
- The Greys: Resemble your stereotypical grey aliens save for having pink-ish skin and their large buggy eyes being replaced by shoujo style eyes.
- Innocent Aliens:
- They eagerly welcome the humans into their ship and offer hospitality throughout their visit. They even take joy in the gifts the Telepathy Club and Reigen offer them afterwards.
- When Mameta ends up being taken by them to their home planet, it turns out that despite their advanced technology they don't exactly have weapons. To the point that the only thing they can do is just run against one of their "natural predators", which is actually just a small ball of fur with spindly legs that Mameta "defeats" by just standing in its way.
- Irony: Turns out the Telepathy club's habit of slacking off, gaming and snacking in the club room isn't too far off from the alien's own lifestyle. Which ends up with them feeling right at home when the aliens let them into their spacecraft.
- Non-Standard Character Design: Their faces look like a professionally done Shoujo manga, though the rest of their design matches up with ONE's art.
- Shoujo: Their faces resemble characters of this genre, and they both wear school uniforms and have a cozy school clubroom table in their UFO.
- What Beautiful Eyes!: Their large shoujo-style eyes are described as "a lovely gaze."
Haruaki Amakusa
Voiced by: Nobuyuki Hiyama (Japanese)
A self-professed yōkai hunter who drops in at Spirits and Such one day. He seeks help in taking down an association of yōkai before they revive their King and drain humans of their life energy.
- The Cuckoolander Was Right: All his ramblings of the demon world and his mission to slay them have some merit as he does find the legendary Yōkai King and his Four Generals.
- Just a Kid: Amakusa's first impression of Mob. Reigen assures him that the unassuming teenager is quite capable of handling himself against whatever may come their way.
- Meaningless Meaningful Words: He speaks in a flood of obscure references, antiquated syntax and off-kilter pauses. Reigen, normally patient with potential clients, finds Amakusa mostly unintelligible and frustrating enough to set off his Rage Breaking Point. Serizawa is only able to pick up on the references due to his hikikomori past: they happen to be locations and events from recently popular MMORPGs.
- Rummage Sale Reject: The man's weird getup—a mix of martial-arts attire, ancient Japanese hairstyle (mizura), arm bracers and a katana—screams either 'LARPing' or 'gibbering mad'. Or perhaps both.
- Shrinking Violet: Despite his robust personality, he has tremendous difficulty presenting himself in front of Reigen and Serizawa during their first meeting.
- Talkative Loon: The yōkai hunter talks incessantly about his mission, and waits around for Reigen to finish up with clients before showering him with... even more talk.
- Downplayed, as Amakusa happens to be right.
- Upper-Class Twit: He comes from a wealthy family and his parents give him a million yen allowance to "support" his yōkai hunting mission.
???% (Spoilers)
Mob's ???% Form
I knew that I would be needed after all.
Each of Mob's explosions have him still in control, at least somewhat. ???% is an exception to this rule. This form activates when Mob goes unconscious in moments of extreme danger, causing his powers to automatically activate themselves in an attempt to protect Mob's body.
Immensely powerful but completely out of control, ???% is a Dangerous Forbidden Technique that allows Mob to turn any fight into a Curb-Stomp Battle at a major cost. ???% will attack everyone and anyone he deems as a threat to Mob's well-being with extreme prejudice, often going against Mob's wishes for a peaceful resolution to fights.
The "???%" arc reveals that he is possibly a Split Personality that acts out Mob's best wishes the only way he knows how... through extreme violence. Many characters also theorize he may, in fact, be an entity entirely separate from Mob himself, which is seemingly confirmed when he takes control of Mob during Chapter 100 and identifies himself as a separate identity—that of the "original" Shigeo Kageyama.
- Adorable Abomination: No amount of unfathomable power, ominous shadows, or Glowing Eyes of Doom can change the fact that ???% is a tiny, baby-faced middle-schooler.
- Arc Villain: He takes this role during the titular ???% Arc.
- Because You Were Nice to Me: In the ???% arc, Ritsu is the only character able to confront ???% and come out unscathed. Why? Because Ritsu acknowledged ???% as Shigeo.
- Cain and Abel: ???% doesn't even trust Ritsu, and accidentally injuring him was what caused Mob to pretty much give up their powers. ???% seems to think little of it, instead focusing on how their relationship with Tsubomi changed how Mob viewed their power.
- Dangerous Forbidden Technique: A unique example insofar as that Mob must be unconscious in order for it to activate. He also hates using it, and seems to be traumatized by the fact that he accidentally used it on Ritsu, hurting him.
- Didn't See That Coming: He's very convinced of his belief that everyone in Mob's life is bad for him. He sees all of Mob's friends as leeches, and views Mob's suppression of his powers to keep them safe as limiting to his own freedom. When Reigen admits he's a fraud to Mob, ???% is visibly stunned, as Reigen is visibly humiliating himself for Mob's wellbeing.
- Enemy Within: Mob used to be much livelier as a child until his accident convinced him to suppress his emotions and powers. All of that became ???%, and he's tired of being locked up.
- Fighting Your Friend: ???% has no qualms about fighting, and even hurting, Mob's friends if they stand in his way.
- Final Boss: He's the last, and most dangerous, antagonist of the overall storyline.
- Fully-Embraced Fiend: Not only does he know he's a violent monster, he demands to be accepted as one and seeks to tear down "Mob" for denying his existence while still making use of his power.
- Heroic Safe Mode: Only activates when Mob is out of commission, and acts to protect his body without regard for any harm or destruction caused.
- I Just Want to Be Free: ???% wants to let his power run wild even if it wrecks the world and hopes Tsubomi can still treat him as a normal person despite that.
- Insistent Terminology: He refuses to call Mob and Reigen by name; in the original Japanese, he refers to Reigen as あの人 (ano hito, "that person" or "that man"). ???% insists he's the real Shigeo, and "Mob" is nothing more than an alter ego.
- Pent-Up Power Peril: He's the direct result of the Emotion Suppression Mob used to keep his powers in check and the ultimate example of why Repression Never Ends Well.
- Person of Mass Destruction: Flat-out the strongest esper in the world by an incredible margin. Unrestrained, he demolishes the city as a side effect of simply walking through it.
- Silent Antagonist: It's a bit surprising to see ???% talking when he finally takes over Mob's body completely, but there was a previous instance—when Dimple tries to assure Mob that the corpses of his family he found are constructs, a barely-in-control Mob (his Explosion Counter is depicted as a smudge) growls that he's lying. The anime makes it explicit that this is ???% speaking with a hateful, much rougher tone of voice.
- Split Personality: ???% is essentially Mob's body on autopilot, having none of the mercy or Nice Guy nature of the normal Mob. Chapter 100 reveals that ???% is a manifestation of Mob's deepest desires that acts as the source of his power. He greatly resents Mob for shunning his own powers despite them saving him time and time again and Reigen for exploiting them.
- Superpowered Evil Side: Easily the strongest of the Explosions, largely in part due to his complete lack of mercy or restraint.
- Villain Has a Point:
- ???% is tired of Mob treating his powers like a taboo even though, more often than not, they were the only way to save themselves and others from harm.
- He also argues that Mob attempting to reject his own powers when Tsubomi wouldn't pay attention to him was a mistake because all her attitude meant was that she could treat him as a normal person when no one else would.
- Lastly, he recognizes that Reigen—the man who taught him that he was more than the sum of his powers—only took interest in him because of them and is still lying to and exploiting him.
- Walking Spoiler: Very little about ???% is revealed up until Chapter 100, where he becomes the Arc Villain and terrorizes Seasoning City, requiring the help of everyone, psychic or not, to take him down.
- Well-Intentioned Extremist: His only desire is to protect himself, but he will go to any lengths to make this happen. In Chapter 100, he nearly destroys Seasoning City in an attempt to make sure that Mob's, or rather, his own Love Confession goes smoothly.
