BABEL provides examples of:

Minamoto Koichi
Voiced by: Yuuichi Nakamura

The main protagonist. He is the field leader of "The Children" Special Esper Team, not only giving them directions during missions but also overseeing their daily care.
  • Above the Influence: Despite the persistent efforts of The Children (and Kyosuke, and Fujiko, and the entire free world...).
  • Action Survivor: While he can put up some fight, he's not nearly as powerful as the espers are, and usually has to rely on them to fight other espers.
  • Awesome by Analysis: Due to his intellect, he can usually figure out some of the things going on simply based on the evidence he sees.
  • Badass Normal: subverted in the pilot chapter where he's (although completely oblivious of it) a level 7 anti anti ESP-er link... which still makes him a normal guy... but in the serialized manga (and anime) he is just a Normal.
  • Batman Gambit: His most common means of surviving in a world filled with people of mass destruction
  • Beware the Nice Ones: When pressed about his old college girlfriend, he gets extremely defensive about it, to the point that even high level espers were scared of him.
  • Bishōnen
  • Butt-Monkey: Minamoto starts out this way in the manga, being thrown into walls by Kaoru at the slightest provocation, taking the fall for the Children's collateral damage, or being messed with by Kyosuke.
  • Canon Discontinuity: In the end of Volume 1, he is revealed as Anti-Anti Esper, basically if he is there it negates Anti-Esper's power and enable the esper(s) to use their ESP. Then, it was completely untouched again like Anti-ESPer ESPer and The Normals.
  • Celibate Hero: Minamoto's life revolves around keeping The Children safe and happy. On the rare occasions when does manage a date he's completely clueless.
  • Chick Magnet: Many of the females in the series are drawn to him. Some comment on his good looks, while others like him because he's a Nice Guy. He's not Oblivious to Love either, he's mostly Above the Influence regarding the Children, and for the others he just simply doesn't have time to date due to his workload with BABEL and the girls.
  • Cunning Linguist: English, Russian, German, French, Italian, Chinese; and some proficiency with Spanish and Korean.
  • Deconstruction: Minamoto of all people experiences this when he learns from Feather that he kills Kaoru in the Bad Future out of Mad Love for her.
  • Even the Guys Want Him: In-Universe. Everyone wants Minamoto; among others, Kyosuke, Sakaki and Okama.
  • Fermat's Last Theorem: Apparently he found a ''new'' proof for it as a boy because he was asked to.
  • Guile Hero: Wins using brainpower.
  • Heroic Willpower: Strong enough to resist the more drastic forms of mind control Kyosuke tries to inflict on him.
  • House Husband: Lampshaded pretty often.
    • According to Sakaki, he'll "make a good bride."
    • A yonkoma depicts the ESP types and how it works, and he.. Has the housewife skills, the power to make dish from leftover ingredients.
    • Chapter 424: Hanae comes to the mansion where the girls lives and cook and cleans in Minamoto's stead, in which Minamoto seems slightly dissappointed he is not allowed to do the housechores. Aoi called the debate "Like a fight between the mother in law and the wife."
    • Chapter 426. Yuuri and Kaoru is having a date, with Yuuri showing "Kaoru's ideal type." Patty and Matsukaze watched them...And Minamoto come to said department store. For what? To buy cookware, and the reaction was epic:.
    Patty: He's casually came all the way to buy cookware !? He's a woman!!
    Matsukaze: And he's just so casually approaches it! Really, is this an Otome Game !?
  • Intelligence Equals Isolation: The girls discover that he was incredibly smart for someone his age when examining an old class picture. Other kids didn't like being outshone by him in class and gradually ostracized him for it. Because of this, despite being a normal human, he is able to sympathize with the plight espers face due to their powers.
  • Megane
  • Minored In Ass Kicking: When he's not fighting someone way over his league, such as a high level esper, he can put up a decent fight.
  • Morality Chain: Initially. Later on in the series The Children become mature enough to make their own decisions.
  • Mr. Fanservice: Photographs of Minamoto in his unmentionables are popular among BABEL's female staff.
  • Nice Guy: Aside from him disciplining the girls for rude behavior, he is generally this.
  • Only Sane Employee: He's one of the only ones who generally doesn't go overboard with his actions. The BABEL chief, in contrast, tends to overreact towards the girls and anything they do.
  • O.O.C. Is Serious Business: No matter how strong, influential or cute you are. No matter even if you are his employer. Make Minamoto snap and you will surely regret it.
    • As an example, when Fujiko tries to ask him about his old girlfriend from college, he tries to skirt the issue. When Sakaki tries to answer it for them, he knocks his friend out, and later when pressed on it, he gets rather angry, and everyone, even high level espers like Kaoru, were quite scared of him.
  • Otaku: a very high functioning one. The man squees like a six year old when he goes to a space museum.
  • Papa Wolf: He tends to get rather protective of the girls anytime they're ordered to do something he deems a bit out of their league, such as having Shiho help the police with unsolved cases by having her touch items recovered from the crime scene, such as a kitchen knife. And especially anytime Hyobu approaches them.
  • Parental Substitute: He is a full time parental figure and role model to at least five very powerful ESPers.
  • Poor Communication Kills: Chooses not to share the full details of the prophecy where he kills Kaoru. Hard to blame him, but it still leads to lots of misunderstandings and hilarity.
  • Screw Destiny: Minamoto actively tries to avert a prediction made where he has to kill Kaoru in the future.
  • Screw This, I'm Outta Here!: There is a time Minamoto gets so angry at The Children that he considers calling quits on being their guardian. Little he knew that in their case making them cry hopelessly is not recommended.
  • Sexy Mentor: Male example.
  • The Strategist: He usually formulates a lot of the plans that BABEL takes. And they usually succeed.
  • Supreme Chef: The man can cook anything. Anywhere.
  • Team Chef: Is quite a good cook. Sakaki at one point jokes that he'll "make a good wife someday" to someone.
  • Team Dad: He's essentially this for the girls.
  • Tsundere: Type B, and completely understandable in his situation.
  • Unwanted Harem: Aside from the three girls he supervises, he's also got several other females that at least show hints of interest in him, such as the Double Face girls and Kaoru's mother and sister.
  • Well, Excuse Me, Princess!: To Kaoru, though the usual gender roles are reversed.
  • Wife Husbandry: Zigzagged. He's not trying to do this, but the kids want him to, not that they want him to wait that long. Everyone else thinks he's trying to, Fujiko wants him to, and in the future, one way or another he'll end up with Kaoru.

Kaoru Akashi
Voiced by: Aya Hirano

A ten-year-old Level 7 psychokinetic and the reckless and zealous member of "The Children" Special Esper Team alongside Shiho and Aoi that often goes overkill with her psychic powers.

Aoi Nogami
Voiced by: Ryoko Shiraishi

A ten-year-old esper with Level 7 teleportation capability, Aoi is the rational member of "The Children" Special Esper Team alongside Kaoru and Shiho that likes playing video games in her spare time.

Shiho Sannomiya
Voiced by: Haruka Tomatsu

A ten-year-old esper with Level 7 psychometry, Shiho is the sarcastic, sharp-tongued and often childishly sadistic member of "The Children" Special Esper Team alongside Kaoru and Aoi.

Taizo Kiritsubo
Voiced by: Jurota Kosugi

The leader of BABEL in terms of most day to day matters.

Oboro Kashiwagi
Voiced by: Masumi Asano

Taizo's secretary, who's often seen with him.
  • Beleaguered Assistant: Can turn out this way at times when the Chief does some over the top things.
  • Beware the Nice Ones
  • Christmas Cake: Implied, as people try to set her up on dates.
  • Cloud Cuckoo Landers Minder: She acts like this towards Taizo when he starts veering off from his actual job of running BABEL.
  • Covert Pervert: Is implied to be attracted to Minamoto
  • Cute Clumsy Girl: In a supplement chapter
  • Hyper-Competent Sidekick: She gets a lot of things done around BABEL when Taizo is goofing off or doing things he really shouldn't be, such as spying on the girls while on a date with a boy. She even gets the Japanese government off of BABEL's back when they question why they're spending so much money on the organization. Due to her sincerity and hospitality, they all agree that it's a necessary function and allow more funding for them.
  • Mission Control: She often performs this role for Minamoto and the girls, providing them with intel for their mission.
  • Nice Girl
  • Office Lady: A Higher ranked example.
  • Only Sane Employee: Other than Minamoto, she seems to be the only one that can usually get things done around work. Certainly when Minamoto isn't around.
  • Reluctant Fanservice Girl: Mostly thanks to Kaoru.
  • Sexy Secretary
  • She's Got Legs: Especially pronounced due to her skirt.

Shuuji Sakaki
Voiced by: Kissho Taniyama

BABEL's chief physician and Minamoto's close friend.
  • Because You Were Nice to Me: He's a little jealous that the Children have Minamoto as a mentor. Growing up, he didn't have anyone like that, and like all espers, he was ostracized too, so often hung out by himself. However, once he meets Minamoto, and sees a human that genuinely wants to befriend espers, he starts to become more likable.
  • Big Brother Mentor: Attempts to be this to Tim Toy and Bullet. He will also occasionally watch over the girls if Minamoto is unable to for whatever reason.
  • Bishōnen
  • Brainwashed and Crazy: By Black Phantom's Gilliam, though it is like a cancer instead of hypnotism.
  • Casanova Wannabe: While it's strongly hinted at that he has a lot of girls' numbers, the ones he tries to hit on onscreen usually turn him down, such as the Double Face girls.
  • Chivalrous Pervert: He may be perverted, but he will still help where he's needed, especially if it's Minamoto or the girls.
  • Combat Pragmatist: He doesn't mind using drugs to sedate his opponent, since he doesn't have any real offensive esper abilities like Kaoru and Aoi do.
  • Crouching Moron, Hidden Badass: Comes off as a skirt chaser and a slacker... until you threaten his friends.
  • Digging to China:He can use his psychometry through the Earth to reach Brazil, which is not impossible considering where he was at the moment.
  • Green-Eyed Monster: Just a subtle one, but he mentions to Shiho that he's a little jealous that she got to meet someone like Minamoto who goes through a lot of trouble to protect her, Aoi, and Kaoru. By comparison, he had no one like that to rely on growing up, so grew kind of jaded and bitter. Until he punched Minamoto at college and saw someone who looked like he cared about espers despite being a normal person.
  • Healing Hands: His psychometry greatly enhances his abilities as a doctor.
  • Inconvenient Hippocratic Oath: In episode 32, after meeting his old college professor at a secret fishing spot, the latter taunts him for being a bad student. He then suffers a stroke, and while Shiho says he got what he deserved, Sakaki mentions that he still has to do what he can to help save the old man's life. In the end he seems to have done so, and also grown a little closer to Shiho, who up to that point was largely confrontational to him.
  • Mind over Manners: In contrast to Shiho, Sakaki uses his powers more or less ethically. (He does examine his female patients' chests a little more often than he should, but in BABEL that's negligible.)
  • Minored In Ass Kicking: Rarely participates in combat, but is more than proficient when he does. This includes sedating opponents stronger than him.
  • The Resenter: Mildly. Sakaki barely conceals his wishes that he had a parent/mentor figure like Minamoto, and can get catty with Shiho over it.
  • Unknown Rival: To Shiho.

Naomi Umegae
Voiced by: Ayumi Fujimura

Another ESPer on BABEL's payroll who occasionally assists the children in the field.

Ichiro Tanizaki
Voiced by: Hiroshi Yanaka

Naomi's supervisor, and would be suitor.

Akira Yadorigi
Voiced by: Fuyuka Oura

One of the members of Hound, and Hatsune's childhood friend. His power is metempsychosis

Hatsune Inugami
Voiced by: Ai Shimizu

The second member of Hound, with a metamorphic synthetic power.

Voiced by: Takashi Kondo

An Esper brainwashed by Black Phantom.

Tim Toy
Voiced by: Junko Minagawa

Another of Black Phantom's victims who finds himself on Babel's pay roll.

Fujiko Tsubomi
Voiced by: Yukana

The official head of BABEL. An esper from the earlier generation and knows Kyosuke from back then.


A group of rogue Espers dedicated to securing ESPer supremacy, often through violent means.

Kyosuke Hyobu
Voiced by: Koji Yusa, Aya Hirano (child)

The leader of P.A.N.D.R.A. and the series' major antagonist.
  • Abusive Parents: Minor case. His father shouted at him and forced to repress his powers, and may have even beaten him for using them.
  • A Father to His Men: Kyosuke has genuine, no-strings-attached feelings of affection and responsibility for his followers, up to taking over a country just to let the kids go to school.
  • Affably Evil: Very. He does have serious moments where he acts like a genuine bad guy, but most other times he just does petty things, such as trying to beat Momotaro at a video game, and losing.
  • All Your Powers Combined: His extra powers were gained from his old comrades, and were passed on to him if he personally watched them die.
  • Amnesiac Dissonance: When reverted into a child, he is nicer, and due to Minamoto, it bleeds over when he comes back.
  • Anti-Villain: Kaoru sees him as such, though Kyosuke is always zigzagging across the Moral Event Horizon. Regardless, his intentions are at least understandable, and he is providing a home and support network for the espers that BABEL isn't able to find or help.
  • Authority Equals Asskicking: He is quite dangerous even though he does get beat from time to time. But that's usually because he wants to give them a Hope Spot before showing a trump card that then takes out whoever he's fighting.
  • Back from the Dead
  • Big Bad
  • Breakout Character: Has his own anime spinoff, The Unlimited.
  • Brilliant, but Lazy: Kyosuke is as intelligent as Minamoto, but is too whimsical to match him tactically.
  • But Not Too Foreign: Backstory tells us his mother is 'from the continent' i.e. Asia.
  • Cast from Lifespan: His "Unlimited Mode" introduced in the spinoff, in which he removes his Power Limiter and becomes even more powerful than he already is, shortens his lifespan every time he uses it due to the unstable nature of his powers (thus necessitating the use of a constant Power Limiter in the first place).
  • Characterization Marches On: In his first appearance, he seemed somewhat more evil and less whimsical.
  • Combat Pragmatist: He's usually willing to do whatever is necessary to win a fight.
  • Creepy Child: Had his moments after joining the military.
  • Depraved Bisexual: Either this or If It's You, It's Okay toward Minamoto. Or just a massive tease.
  • Draco in Leather Pants: In-universe, Kaoru is unbelievably willing to forgive his crimes.
  • Dull Eyes of Unhappiness: The default state of his eyes after his Start of Darkness, regardless of whether he's angry or smiling or contemplating sweet murder.
  • Evil Cannot Comprehend Good: He feels a war between espers and normals is inevitable, and constantly works in subtle way to try and speed things up. However, Fujiko and Minamoto both refuse to believe that, and feel that espers and normals can get along, hence BABEL's existence and why they're trying so hard to ensure the girls grow up with a somewhat healthy and normal childhood. As a result, they often end up at odds with each other.
  • Friendly Enemy: To BABEL, particularly Minamoto and The Children.
  • Freudian Excuse: The reason he's so distrusting of normals, Minamoto in particular, is because his commander when working in the Japanese military had come off as a very reasonable kind man who wanted nothing more than coexistence between espers and normals, but then tried to murder Hyoubu and made it clear that his ideal world was one in which humans control espers. Because of him, Hyoubu has trouble bringing himself to trust normals who work towards coexistence between espers and normals.
  • I Shall Taunt You
  • Like Brother and Sister: With Fujiko, before and during the war. He even called her "sis".
  • Limited Wardrobe: Nothing but gakurans. Getting him to wear more normal clothes have ended badly in the past.
  • Locked into Strangeness: His hair was originally black. It turned white over the years.
  • Manipulative Bastard: He's willing to play dirty to achieve his goals if he has to.
  • Master of Illusion
  • Morality Chain: Kaoru is this to him. He will often stop what he's doing to help her out, or provide a clue on what to do about the current crisis, and in some cases will do dirty work behind the scenes to prevent Kaoru from having to get her hands dirty, such as killing an esper controlled by Black Phantom.
  • Mystical White Hair: His silver hair is the only physical nod to his actual age.
  • Not So Above It All: He may be a criminal mastermind, but he still tries to show up Minamoto from time to time, such as making a boxed lunch for Mio after she reminisced about Minamoto's cooking, or trying to beat Momotaro at a video game, losing badly, and still insisting on playing more. He also finds it hilarious when Minamoto is taken control of by some flies, and try to make him do silly things such as drink from a toilet.
  • Older Than He Looks: Despite having the appearance of a high schooler, he is at least 80 years old.
  • The Only One Allowed to Defeat You: He takes this stance at times when helping out BABEL/Minamoto. While he would love to see them fail, he also realizes that upsetting Kaoru would work against his goal of trying to make her the esper queen.
  • Parental Substitute: Seemed he found one in commander of his ESP unit. Poor kid.
  • Pet the Dog: As underhanded as he acts at times, he does have these moments where he'll protect Kaoru or help out Minamoto, even if his objective to have Kaoru do a Face–Heel Turn ultimately fails.
  • Physical God
  • Playing with Fire: Received from an old comrade, after he died.
  • Psychopathic Manchild: In Volume 6, he does avenge a young girl who is severely wounded in a suicide bombing - but only because the bomber ruined the good mood brought on by the flowers she sold him and because she looks astonishingly like Kaoru. Later, he says to the leader of the terrorist group (before he blows up the plane they're on):
    Kyousuke: I go anywhere my interest leads me. I do anything I want to. I kill anyone I don't like. That is all.
  • Reality Warper: Between his highly-refined telekinesis and hypnosis, Kyosuke can do just about anything.
  • Supreme Chef: While this doesn't crop up often, Mio did comment that his boxed lunch was delicious. One of his henchmen notes that he's being immature because he made said lunch solely because Mio was reminiscing about Minamoto's cooking a while back, and wanted to show him up.
  • Used to Be a Sweet Kid: Before his beloved commander tried to kill him.
  • Utopia Justifies the Means: There will be a war between humans and espers. Kyosuke wants to make sure the esper side wins, whatever the cost.
  • Villainous Crush: He wants Kaoru as his queen.
  • Villain Protagonist: In The Unlimited.
  • Vitriolic Best Buds: With Momotaro.
  • Well-Intentioned Extremist: While PANDRA's main goal seems to be making sure that espers win the war between normals and espers, should it ever come, but it's implied that he'd be perfectly fine with a world in which humans and espers can coexist peacefully. The problem is he doesn't think that it's possible. Also, PANDRA's actions rarely ever directly harm civilians, espers and normals alike.
  • White Hair, Black Heart
  • You Have Outlived Your Usefulness: His Start of Darkness. He himself averts this utterly; see A Father to His Men above.
  • Your Days Are Numbered: Brought up early in the manga but then ignored; resurfaces in the spinoff anime.

Mio Tsukishi
Voiced by: Rie Kugimiya

A young level 6 teleporter in PANDRA. Mio spends a great deal of time trying to gain Kaoru's affection without admitting that she wants to be friends.
  • Affably Evil: While her introduction was rather violent, kidnapping Minamoto to force Kaoru into a showdown, she is a rather incompetent villain. Even when he was kidnapped, Minamoto ends up cooking some decent food for her after noticing she just ate instant noodles. He even cleans her clothes for her after recommending she take a much needed bath as well.
  • And Your Little Dog, Too!: Frequently makes threats against against Kaoru before she admits that she really wants Karou's friendship.
  • Because You Were Nice to Me: Hyobu showed kindness to her when she was younger, hence why she willingly joined him and worships him.
  • Body Horror: Her first fight has her teleportation powers run amok.
  • Clingy Jealous Girl: Hates Kaoru because of the attention Hyobu gives the former over her.
  • Dark and Troubled Past: Implied.
  • Dark Magical Girl: Much more vicious than The Children.
  • The Ditz: Can be a bit slow to realize things like "having no air will kill you."
  • Green-Eyed Monster: Mio resents that The Children, Kaoru especially, received many opportunities that she was denied.
  • I Just Want to Be Normal
  • She Cleans Up Nicely: When Minamoto washes her clothes and she takes a bath.
  • Social Services Does Not Exist: Until Kyosuke reorganized PANDRA, Mio was living in a cabin, on her own, eating virtually nothing but ramen.
  • Teleporters and Transporters: Her teleportation allows her to teleport only a part instead of the whole like the others. The parts are still connected and if they are too far apart or too far away from Mio, they will reattach on one side.
  • Tsundere
  • Vitriolic Best Buds: To Kaoru.
  • Zettai Ryouiki

Shiro Magi
Voiced by: Koji Ochiai

Kyosuke's right hand man and secretary.

Masuo "Muscle Okama" Ookama
Voiced by: Kenta Miyake

One of PANDRA's ESPers and Mio's most frequent partner in crime.

Takashi Kugutsu/Mr.9
Voiced by: Yukito Soma

  • Adaptation Expansion: The anime gives him stronger motives for Face–Heel Turn, making him more sympathetic.
  • Blessed with Suck: In episode 21 of the anime, he tells Hyobu he was constantly being ignored, such as being skipped over for attendance in class, which he exploits by taking pictures of Babel employees without their knowledge. He then says he has to practically punch someone in the face before they'll even notice him, which also comes back to bite him when Kaoru nearly walks over him while he's spying on Oboro Kashiwagi.
  • The Dog Bites Back: Being always mocked for his hobbies by Sakaki makes it that much easier for him to join PANDRA for good; he nearly murders Sakaki in the process.
    • In the anime, BABEL really had it coming when Kaoru blackmailed him into building an anatomically-correct Oboro doll for her, then just left him holding the bag when it was discovered, causing him to lose out on his chance to ask out the girl he really liked, Ranko Kaneko, who then subsequently goes on a date with Sakaki after she misinterpreted the accusations that he liked Kashiwagi.
  • Face–Heel Turn: While he was a spy for Hyobu in the first place, he never actively worked against BABEL until the Trauma Conga Line he suffers from them. He then tries to frame Sakaki as a spy, and after that fails, openly joins PANDRA.
  • Freudian Excuse: His coworkers' general disdain for his hobby gives him another reason to spy on them for PANDRA.
  • Marionette Master: As an esper, Kugutsu can manipulate dolls with life-like accuracy. Also, this.
  • Otaku: A doll/figurine otaku to boot. Never to be seen without a LiccaMoga-chan doll.
  • The Mole: In episode 21 of the anime, it's revealed that he's the one giving intel on BABEL espers to Hyobu.
  • Rewarded as a Traitor Deserves: Subverted. Kugutsu is truly appreciated in PANDRA for his abilities, otakuism notwithstanding.
  • Spoof Aesop: for Tim and Bullet's sake.
  • Start of Darkness: After suffering a humiliating Trauma Conga Line thanks largely to Kaoru in episode 21 of the anime, he vows revenge on all the people who humiliated him, and worse, ruined his chances of giving a Love Confession to Ranko Kaneko, a BABEL technician and girl he was really interested in.

A telepath, and Mio's bodyguard.

    Black Phantom 

Black Phantom
The leader of the organization of the same name, which brainwashes Espers and uses them as assassins.

  • Battle Butler: A notable aversion: despite the way he dresses and his loyalty to Black Phantom, he lacks Psychic Powers or other combat abilities.

Phantom Daughter/Yuri Kumoi/Mirage/Phantom
One of The Children's classmates. Actually Black Phantom's daughter, a Hypno user with a split personality. The Yuri personality knows nothing about Black Phantom and has no special abilities; Mirage, who considers herself the main personality, created her to fool Psychometers.

A young girl who is a Black Phantom agent.
  • Brainwashed and Crazy: Though she is broken out of it later.
  • Shadow Walker: She can teleport herself or somebody else through a shadow.
  • Creepy Child: So brainwashed that she smiles when revealing that Black Phantom has put a device in her forehead that will kill her if Kaoru removes her brainwashing.

  • Hazy Feel Turn: Joins PANDRA to keep Yuri safe.

Ninja Hanzo
An adult Black Phantom agent.

A young man who is an agent and son of Black Phantom. Yuri's elder brother.

A mysterious, very powerful Esper whose mind can be transferred between bodies using raremetal quartz. She has amnesia, but has a vague idea that her goal is to "change the future". In love with Minamoto (even more so than everyone else).

Chisato Hanai
Voiced by: Kaori Fukuhara

A level 2 esper who goes to the same school as Kaoru, Shiho, and Aoi does.
  • Break the Cutie: She accidentally outs the three girls as espers when they first go to school, which causes some problems for them. She also accidentally read Tono's thoughts about not caring if she was an esper, but when she accidentally reveals it and he finds out later, he gets rather mad at her.
  • Clingy Jealous Girl: She absolutely hates it when Tono mentions not liking her.
    • In episode 33, imagining him doing things with Kaoru when the two get lost looking for the latter's lunch during a class field trip gets her rather angry.
    • In episode 50, he gives his notebook to her so she can take notes, then asks Mio to share hers with him. Chisato is absolutely furious about that turn of events.
  • Locked Out of the Loop: She is unaware of the Children's association with BABEL. Anytime she tries to pry into it, they give her some rather vague answers.
  • Patient Childhood Love Interest: To Tono.

Masaru Tono
Voiced by: Rina Sato

A young boy who's attending the same school as the girls.
  • Butt-Monkey: He's sometimes on the receiving end of the girl's anger, sometimes deserved, other times not so much, especially with Kaoru.
  • Fantastic Racism: He despises espers at first, and nearly gets into a fight with Kaoru over it. However, he seems to lose this trait as the series goes on.
  • Locked Out of the Loop: Like Chisato, he's unaware that they work for BABEL and are actually more powerful espers than they claim to be. It helps that the girls obey Minamoto's order to not use their powers at school, such as when Kaoru wanted to blast him to the other side of the classroom after provoking her into a fight.
  • Muggle: He is absolutely normal unlike some of the girls in his class.
  • She Is Not My Girlfriend: While it's strongly hinted that he does have feelings for Chisato and hangs out with her quite a bit, he will often deny this if it's brought up.
  • Worthy Opponent: Views Kaoru as one after she manages to play him to a draw in a game of dodgeball.
