Muhyo and Roji's Bureau of Supernatural Investigation

     Toru Muhyo
Voiced by: Ayumu Murase

One of the two heroes of the story. Muhyo is a genius executor who managed to graduate at a very young age. He opens a ghost bureau which specializes in exorcising malevolent ghosts.

  • The Ace: Pretty proficient in his craft and the most relied on when against bigger threats.
  • Big Eater: Very if he wakes up after a tough fight.
  • Big Guy, Little Guy: The little to Roji's big. Guy doesn't seem to have grown any even when he was a student at MLS.
  • Brilliant, but Lazy: Not exactly one to jump into action unless prompted. Otherwise he spends most of free time either reading manga or sleeping.
  • Brutal Honesty: Muhyo doesn't sugarcoat things, he'll always speak his mind and be completely direct. It makes him come off as harsh but in the world of Magical Law where a moment of hesitation can cost you your life, a lot of what he says has a point.
  • Child Prodigy: Graduated at a very young age. He's described as one of the tougher executors MLS has produced and can summon high level envoys thought impossible including Hades himself.
  • Deadpan Snarker: Never misses an opportunity to be one.
  • The Greatest Story Never Told: Prefers staying out of the limelight and keeping his business small scale, as he doesn't want his bureau to be bombarded by reporters and unwanted attention.
  • Heavy Sleeper: Sleeps a lot, especially if he uses up too much of tempering.
  • Heroic RRoD: Does this often against tougher ghosts since summing high level envoys takes up all his tempering to the point of being life threatening.
  • Invincible Hero: Subverted. Muhyo's powerful and has a notable win streak, but he has to rely on his envoys to do the heavy work and in most cases when needing to do longer incantations, has to rely on his friends to run interference and protect him. In a lot of the latter's circumstances, it uses up a lot of his tempering to the point he needs medical treatment.
  • Jerk with a Heart of Gold: Very aloof and blunt to many who meet him, but he always has people's best interests in mind and willing to give repentant ghosts a lighter sentencing.
  • Nerves of Steel: Very cool under pressure to the point where he hardly ever panics and has done many an impossible feat.
  • Secret Test of Character: How he wound up picking Roji for the job. The other applicants he interviewed were just in it either for fame or Muhyo's attention. He picks Roji because of his honesty and his willingly to selflessly help people as he noticed during a ghost attack. Having some untapped power doesn't hurt either.
  • Silly Rabbit, Idealism Is for Kids!: The guy is a bit of a realist and, while he'll always strive for the best option, he knows that not every dilemma he and his friends face will have the prettiest outcome. This is something he make sure to let both his allies and clients know.
  • Summon Bigger Fish: Essentially how his powers work. He has to summon a much more powerful ghost to deal with the ones they confront.
  • Trickster Mentor: Toward Roji, he may talk down and belittle him, but he knows that Roji has a lot of potential and wants him to succeed at whatever he plans to do, be it working for him or becoming a judge himself in the future.

     Jiro “Roji” Kusano
Voiced by: Yū Hayashi

Muhyo's assistant and the other of the two main heroes.

  • Almighty Janitor: Many characters note that he could be a great judge in his own right, but he chooses to stay by Muhyo's side.
  • Big Guy, Little Guy: The big to Muhyo's little.
  • Child Prodigy: Not to the extent of Muhyo but many notice that he has a surprising synergy with him and a lot of untapped power which, become useful in major fights.
  • Crouching Moron, Hidden Badass: May seem like a wimp but he has a lot of determination. Many opponents end up defeated when they don't take him into account.
  • Only Known By His Nickname: No one calls him Jiro, it's always Roji.
  • Power Limiter: In the past, Page saved him and his friends from a ghost attack and noticed Roji has a lot tempering leaking out his body which was attracting the ghosts. So, he sent him a bolo tie that was meant to keep his powers in check.
  • Spanner in the Works: Toward a lot of Ark's schemes. Teeki was so focused on Muhyo that he didn't know that Roji was a major factor in his strength. By the time he did, he plans were crumbling around him and it's ultimately Roji that stops him from taking Enchu's body. Teeki even lampshades he should've killed Roji first.
  • The Heart: Of the duo, he's the one that displays the most empathy and manages to keep Muhyo going. Though Muhyo won't admit it, he's actually finds Roji very vital to their dynamic and knows he's destined for greatness.
  • Wide-Eyed Idealist: Believes the best in everyone, even some of the ghosts that they fight. However, this has gotten him in trouble with spirits that are willing to take advantage of him.

Human World

     Kenji Satou
Voiced by: Kouhei Amasaki.

A bratty kid who initially doesn't believe in ghosts.

  • Bratty Half-Pint: Well he is a kid after all, he does get better as he gets to know the duo.
  • Hidden Depths: Shown in one chapter to know how to the play the recorder. It is actually essential to placate a ghost haunting his room.
  • Out of Focus: He doesn't show up much in later chapters, mostly due to a lot of the action taking place in areas away from the city where Muhyo and Roji's office is.
  • The Promise: After his hears that Muhyo and Roji are going on a dangerous mission and might not come back, he leaves his prized baseball cap with then and makes them promise to return it, basically as incentive to come back alive. They make good on their promise.
  • Too Dumb to Live: In order to prove ghosts don't exist, he takes a dare to go to a shrine on the edge of town and pull off the seal on it (at night no less). Not surprisingly, this unleashes the malevolent ghost within who nearly eats him and his friends. Luckily Muhyo arrives in time to save them.

     Nana Takenouchi
Voiced by: Iori Nomizu

A neighbor of Kenji's who he introduces the duo to, as well as a budding photographer.

  • Achievements in Ignorance: She actually has latent spiritual powers making her a shaman.
  • Camera Fiend: A budding photographer. She takes a job at MLA as one later in the story.
  • Distressed Damsel: Gets kidnapped by ghosts at the start of the Vector arc, though she manages to escape with the help of Sanpu.
  • Heroic Sacrifice: At the start of the Vector arc, she pushes Kenji out of the way when a ghost attacks them. She doesn't die, thankfully.
  • Irony: Her father made a business selling fake photography of ghosts. Turns out she's a medium. Muhyo guesses it was always genetic in her family, they just never realized it.
  • Never Got to Say Goodbye: To her father following an argument. She eventually corrects this when she encounters his ghost.
  • Parental Abandonment: Her mother left both her father and her when she was little and her father dies of a heart attack right in front of her.


Goryo Office of Magical Law

     Daranimaru Goryo

An Executor with his own magical law offices who tries to hone in on Muhyo's territory.

  • Big Damn Heroes: He and Ebisu show up just when Ivy is about to the confront the group for the Writ of Passage when they're still recovering from the Gingko Hag, fighting her in their place.
  • Break the Haughty: After Tomas knocks him down a peg, destroys his main office building and nearly turns him into a half-gast, he starts losing his condescending attitude.
  • Baleful Polymorph: Gets this inflicted on him by Tomas, nearly turning him into a half-gast. Luckily Kiriko manages to purge the worms that were changing him out of Goryo.
  • Cruel Mercy: After he beats Ivy, he doesn't kill her and was going to have her taken to the Arcanium where she could reflect on her actions for the rest of her existence. However, Ivy teleported from the area and was later killed by Buhpu.
  • Heel–Face Turn: After the encounter with Tomas and seeing the effort Ebisu would go to save him, even after firing him, he turns over a new leaf and starts acting humbler and more caring.
  • Heel Realization: After he was saved from Tomas and seeing Ebisu nearly die trying to do so, he begins to realize his former methods were flawed.
  • Jerkass: Initially and was a major one at that. He practically bullies many budding magical law offices, taking each one of them as their own, charges an outrageous fee for his exorcisms with the threat of releasing the ghost he captured back on their victims if they don't pay up (even when said victims don't even know what's going on), puts Nana in danger during his competition with Muhyo and Roji, and fires Ebisu for seemingly screwing up one of their exorcising techniques.
  • Out of Focus: After the Ivy fight, he makes scant cameos through the series but never plays a major role again.
  • Pyrrhic Villainy: He manages to beat Muhyo in their competition and gain his office, but only on a technicality (which Muhyo himself points out, he practically forfeited). Muhyo was still the one who beat the major spirit threat during the event and Goryo can't enjoy the victory with the knowledge that Muhyo is still the better executor.
  • Sympathy for the Devil: After he and Ebisu find Ivy after Buhpu kills her, Goryo gives her his umbrella hoping it'll provide some relief for her as she passes on.
  • Think Nothing of It: After he gives Muhyo and Roji their office back.

     Hanao Ebisu

Goryo's assistant.

  • Dark and Troubled Past: A street urchin who was raised as an orphan and made no friends. When he found out he had medium powers, he used it to commits robberies by using a spirit. However, one of his targets had a practitioner nearby, which fended the spirit off. The spirit took revenge by draining Ebisu of his tempering and leaving him for dead in a sewer until Goryo found him and nursed him back to health.
  • Heel–Face Turn: Along with Goryo, he becomes much nicer after bonding with Roji during the practitioner exams.
  • Hero Worship: Toward Goryo since he's the one who saved him from a life of homelessness.
  • "I Know You're in There Somewhere" Fight: After Tomas infects Goryo with worms and nearly turns him into a half-gast, Ebisu tries his best to get him to fight against it. Unfortunately, Tomas's control is too strong and Goryo nearly kills him by impaling him.
  • I Owe You My Life: Feels this way to Goryo for saving him when he was on the brink of death.
  • Jerkass: Initially, although he gains some sympathy points since even he wasn't spared from Goryo's dickery.
  • Monster Clown: Has the appearance of one, his nose being the main feature.
  • Not So Different: With Roji, while Ebisu's a judge, he knows all too well the feeling of worrying about his mentor and wanting to get stronger to help him.
  • Out of Focus: After the Ivy fight, he makes scant cameos through the series but never plays a major role again.
  • Undying Loyalty: To Goryo, even after he fires him, he comes to his rescue after Tomas kidnaps him.

  • Beware the Silly Ones: He can be formidable when he gets serious.
  • Big Damn Heroes: Arrives just in time to save Biko from a Face Heel Turned Rio.
  • Book Dumb: Wasn't the brightest student back then and didn't take his studies seriously. He lampshades it a bit during the fight against Tomas.
  • Lovable Sex Maniac: Constantly talks about girls and hits on Nana whenever they meet.
  • The Lancer: Usually leads when chapters focus on him with a group and Muhyo's not around, even though he's not quite as powerful.
  • Thanks for the Mammary: Loves to do this to Nana, naturally it gets him slapped.
  • The Worf Effect: Sometimes is the first one to take damage in fights, he lampshades it during the battle against Tomas.

Rio's assistant and a maker of magical tools.

  • Gadgeteer Genius: Is the one that makes many of the magic tools Muhyo and Roji use as well as being able to fix them when they get broken.
  • Get a Hold of Yourself, Man!: Does this to Rio after they save her from Teeki and she has a break down over learning the truth of her mother's death.
  • Morality Chain: Somewhat one to Rio. While it's not enough to prevent her betrayal, she is the one that ultimately convinces Rio to come back to the MLS.

  • Broken Pedestal: Toward Biko after her treachery is revealed. Though becomes a rebuilt one after she comes back to atone for her crimes.
  • Dark and Troubled Past: Lived with her mother when she was younger and supported her doing demeaning work for a few jerkass MLA members. When a ghost attacked her home and her mother, she tried get the same people to help but they refused and she watched her mother die before her eyes. While it seemed like she had moved past it, in truth she had joined Ark after meeting Enchu and started working as a mole for them.
  • Heel–Face Revolving Door: She joins Ark after her mother was killed by a ghost and none of the MLS people she was working with at the time would help her. She seeks both revenge and a way to bring her mother back, turning on her friends in the process. However, once it's revealed that Teeki had manipulated the events, she returns to the MLS.
  • High-Class Glass: Wears a monocle on her right eye.
  • The Mole: Is one for Ark until she tries to kill Muhyo.
  • My God, What Have I Done?: Once Teeki's manipulation is exposed, she has a breakdown when she realizes she was being used the whole time, even more so as her actions lead to the death of three MLA members (one who was Imai's assistant and two of whom were a couple). Luckily Biko and the others help her get over it.
  • Nice Hat: Wears one in her normal outfit.
  • Regretful Traitor: After she reveals her allegiance with Ark, it becomes obvious she shows no pleasure in trying to kill her former friends and later, while trying to unseal the Forbidden Book, she has a solemn look as she works on it but figures she's already in too deep to turn back now.
  • Walking Spoiler: To people just starting to read the series.
  • Welcome Back, Traitor: Despite having allied with Ark, her friends forgive her after learning the circumstances to her betrayal. Biko in particular was more than happy to have her teacher back.

     Page Klaus
Voiced by: Wataru Hatano

The head instigator of MLS who once taught Muhyo, Yoichi and Enchu.

  • Beware the Silly Ones: He can be a bit goofy and overly-energetic, but when he gets serious he can be pretty damn intimidating.
  • Dirty Old Man: Loves the young girls.
  • Determinator: Almost literally goes through Hell and back to save Enchu.
  • My Greatest Failure: Blames himself for letting Enchu fall to the dark side and does all he can to bring him back.
  • Papa Wolf: Towards all his students.
  • Secret Test of Character: Pretty fond of these; His examination was to test to see if practitioners had the power needed to fight off ghosts and he gives one to Roji to see if he has the resolve to keep helping Muhyo.
  • Sink-or-Swim Mentor: The second phase of his exam was to use some low-level ghosts (harmful but not life threatening) to test out quick thinking on the practitioners' part. This winds up backfiring when a high level ghost manages to blend in with the pack.

     Reiko Imai
Voiced by: Mitsuki Saiga

A judge who is head of a magic prison, Arcanum.

  • Action Girl: Said to be proficient in swordplay (which she proves during Panza's attack) and is more than capable of holding her own.
  • Badass in Distress: She is captured by Ark at one point and makes to escape while trying to bring Rio with her before Mick re-captures her.
  • Red Herring: Was thought to be a disguised Sophie after the heroes manage to find her unconscious body. Turns out Sophie didn't like her face and left her be.
  • Heroic Sacrifice: Does this a good chunk of the time. In her introduction, she orders everyone to evacuate from the prison after Sophie breaks out and stays behind to seal the entrance from the inside to keep anyone from getting in or out. Later after Rio reveals her betrayal and she gets separated from them, she orders the others to go on without her while she goes to save the remaining judges that are still trapped inside the burning prison.
  • My Greatest Failure: Seeing her assistant die, even sadder was that he had put in a transfer from the prison and was seven days away from it.

     Lili and Maril Mathias

Two twins who Roji meets while going to take practitioner exams. Eventually revealed to be researchers of magical law.

  • Creepy Twins: They always seem to talk in sync with each other and even know people's names before they meet them, as well as exposing information that was thought private. The other characters really don't know what to make of them other then that they're on their side.
  • Maybe Magic, Maybe Mundane: The manga seems to imply they're benevolent spirits, though nothing is really confirmed about them by the end of the series.
  • Nice Hat: Maril wears a top hat.
  • Stealth Hi/Bye: Pull this on the heroes a few times.

     Umekichi Sasanoha
Click here for spoilers 

A fellow student at MLS and Busujima's assistant.

  • Cowardly Lion: Constantly doubts himself and usually panics at the first sign of mortal danger, but he can be counted on when things get rough, especially if Busujima is in danger.
  • Everything's Better with Spinning: His main attack is the Dragon's Wheel which allows him to spin into enemies.
  • Nice Hat: Wears one when he's in human form.
  • The Reveal: He's really an envoy that works with Busujima. The reason he can remain in the human realm is because she gave him half her soul.
  • Voluntary Shapeshifting: Can change into a human form and his regular mouse form at well.

     Harumi Busujima

A friend of Imai, a fellow judge, and boss of Umekichi.

  • Gag Boobs: Not too large, but a few jokes are made about them.
  • Improbable Weapon User: Sorta, her magic law book is actually in the shape of a gun which she uses to summon envoys.
  • Parental Substitute: Treats Umekichi more like a son then an assistant and envoy.
  • Hard-Drinking Party Girl: Loves her alcohol and is very jovial, much to the chagrin of Imai and Umekichi sometimes.
  • Shameless Fanservice Girl: At one point she comes out of a hospital room with the bandages over her upper body unfurling, exposing her breasts. She doesn't seem to notice or mind most of the males staring at her.

     Ginji Sugakiya

A fifth-year student who Roji meets at an artifact warehouse. Already an assistant judge.

  • Almighty Janitor Quick thinking and very creative with the tools he has at his disposal, but still stuck as an assistant judge.
  • Death Glare: Gives one to Ziglo when he was hassling Roji.
  • Fiery Redhead: His introduction to Roji was to punch him after mistaking him for a thief.
  • Out of Focus: After Teeki's defeat, he only gets one more appearance where he comes to Muhyo to find out what's wrong with Q-La, and that's it.
  • Not So Different: He actually sympathizes with Bobby about working as hard as he can but never seeming to get anywhere, since he's been an assistant judge for a long while.
  • Senseless Sacrifice: Not the death kind, but he gives his blood up to Q-La in order to keep them from being stranded in Elysium. Then it turns out it wasn't necessary at that point as they made it out fine anyway. Though luckily it didn't go to waste during the final battle against Teeki..

     Futaro “Sanpu” Mitani and Kage

A student based in the North Branch of MLA and his pet bird. Nana meets them during the incident with Vector.

  • Eyepatch of Power: Kage has one, oddly enough.
  • Exposition Fairy: Sanpu fills us in on what Vector is planning to do to the the people he's captured as he and Nana sneak around the passage.
  • Talking Animal: Well Kage is kind of a parrot, though he doesn't go into parrot speak.

     Shooter George

One of the Executors whose wields a sword and actively fights against spirits.

  • The Aloner: By his own decisions as he didn't want to see anyone close to him die in front of him.
  • Freudian Excuse: He actually had friends during his early days at the MLS, but they all died in the line of duty and people started calling him "Shinigami George". He ultimately decided to continue his studies by himself and distance himself from others.
  • Heroic Sacrifice: He doesn't die, but he offers to buy time against Vector and Kuguri while Roji tries to wake Muhyo. He gets impaled during the fight.
  • Jerk with a Heart of Gold: Comes off as a bit glory seeking and prevents Muhyo and Roji from participating on the raid on the Northern branch. But in truth, he was actually looking out for them since Muhyo was constantly drifting in and out of sleep thanks to his tempering being stolen and thus would be no use in a fight. When he confronts Roji later about them coming along on the mission anyway, Roji sees right through him since he's way too similar to Muhyo.


The main villains for a good chunk of the series. They're a group a people who use forbidden arts and hope to destroy the MLA for various reasons.


Head of Ark. Seeks to bring down the MLA while becoming all powerful in the process.

  • All of the Other Reindeer: His Start of Darkness, he was a talented magic law practitioner when working with in the MLA. But the residents back then discriminated against him since he was an outsider and eventually cast him out. He vowed revenge as a result.
  • Big Bad: Not for the whole series, but he's a major threat through most of it.
  • Big "NO!": After his defeat as Hades drags him down to hell.
  • Body Horror: Can split his body into to two, turning it into a mouth of sorts to eat his targets.
  • Dragged Off to Hell: His ultimate fate after he's cut loose from Enchu.
  • Dynamic Entry: When he comes after Imai, Umekichi and Seven-Faced Dog, he blasts right through several buildings.
  • Fate Worse than Death: What Hades promises to show him as he drags his soul down to Hell.
  • Grand Theft Me: How he has survived for many centuries, by binding himself to different hosts to prolong his life. This is what he ultimately had planned for Enchu. In fact, just to keep himself going, he took over the body of Enchu's Mother.
  • Human Shield: After partly taking over Enchu's body, he's confident the heroes won't attack him without having to kill Enchu. However, the fusion only works if the host is willing, and Muhyo manages to throw doubt into Enchu's mind by revealing Teeki's deception, which is enough to separate the two so that Roji can deliver the final blow with the Dagger of Absolving to cut the two loose.
  • It Amused Me: He actually lets Imai take Rio and go after bringing her to the Wailing Vale, just to see her struggle to get away from Ark. Winds up backfiring when the heroes manage to teleport Rio and her out of the area after beating Mick.
  • Malevolent Masked Men: Always seen with a mask until he's finally defeated.
  • Manipulative Bastard: His greatest trait, he loves to get inside the head of particularly desperate people and twist their needs to work for him. This was how he got Enchu and Rio to work for him: by killing their loved ones and making them think the MLA was at fault.
  • Oh, Crap!: Does this when he sees that Muhyo managed to summon Hades as an envoy.
  • Offhand Backhand: So powerful that when he was holding Roji by the throat, a few judges take the opportunity to attack him with an envoy. Without even having to look at the envoy, Teeki uses his powers to completely destroy it while continuing his rant to Roji.
  • Really 700 Years Old: 800 years to be exact.
  • Villainous Breakdown: After the heroes manage to combine the Writ of Passage with Muhyo's law book, he really starts losing it, grabbing Roji and trying to bargain with Muhyo to keep him at bay. Of course, Muhyo has Hades on his side, so all threats and pleas fall on deaf ears.

     Soratsugu “Enchu” Madoka
Voiced by: Hiroshi Kamiya

Muhyo's former friend who turned against him and the MLA after Muhyo was offered the job of executor over him. He seeks revenge as a result.

  • The Atoner: After Teeki is defeated, he accepts his punishment of being locked in a prison and continues his studies to be an executioner to make up for his actions. He even aids Roji in waking up Muhyo during his tempering-loss coma.
  • Big Bad Duumvirate: With Teeki, it's both of their actions that drive a good chunk of the plot.
  • Blinding Bangs: For most of his appearances his hair drapes over his eyes. When his eyes start becoming more visible, it's a sign that he's regaining himself. By the end of the series, his bangs are completely parted.
  • The Dragon: To Teeki for the most part.
  • Driven by Envy: Part of the reason he becomes evil, he thinks Muhyo was trying to take his position away from him. However, he doesn't know that Muhyo was willing to give him the job as he knew Enchu needed it more, which only mounted in trying to provide for his mother.
  • Fusion Dance: Becomes something of a Soul Jar to Teeki after his body is destroyed. Teeki tries to take him over later, but it turns out Teeki always had this in mind before even meeting Enchu after seeing his rivalry with Muhyo.
  • Rival Turned Evil: An unintentional example. Muhyo never wanted to upstage him nor was he trying to compete with him during their studies. But his natural talent didn't sit well with Enchu, which wasn't helped by all the praise people were heaping on him. Combined with the stress of providing for his mother and having to deal with her death, it warped Enchu's mindset to think that Muhyo deliberately was trying to outshine him.
  • Start of Darkness: He was trying to become an executioner to support his sickly mother, to the point he worked himself tirelessly to achieve it. However, he became a bit unhinged when he saw Muhyo's talent, knowing that he could be picked to be one (even though this was unintentional on Muhyo's part). The final straw came when his mother died and he had returned home from her funeral to see that his prediction about Muhyo had come true. After this, he lost it and focused his efforts on killing Muhyo.
  • Used to Be a Sweet Kid: He was really a nice kid who Muhyo and Yoichi treasured as a friend and were worried about when he worked himself tirelessly to provide for his mother. Just a lot of bad timing turned him over to the dark side.


A former teacher at the MLS and former friend of Page who is obsessed with collecting things.

  • Body Horror: His Armor of Flies transformation, as well as what he tried to do to Goryo after he captured him.
  • Collector of the Strange: Has a major obsession with collecting things and his goal is to make "The Ultimate Collection". This was what tipped off Page back then that Tomas wasn't as kind as he looked when he "borrowed" a student's scrapbook of pressed flowers and reacted savagely when Page tried to take it back. When Muhyo's group confront him, they find rows of shelves with all sorts of random knickknacks... who are actually people he's transformed.
  • Curb-Stomp Battle: Takes out Goryo near instantly when they confront each other.
  • Drunk with Power: After he gains the Armor of Flies, he starts to absorb everything left and right
  • Evil Former Friend: To Page, though how much of it was genuine is debatable since it's revealed he faked his credentials while teaching at MLS and is really a criminal.
  • Evil Teacher: To Goryo as he was a former teacher of his, explains a lot really.
  • For the Evulz: He, along with Buhpu, are the only members of Ark without any Freudian Excuse to back up their actions. Tomas is just evil to the core and relishes making people suffer while laughing at their struggles. The fact that he was a criminal before learning about forbidden magic only makes it worse.
  • Human Shield: Uses Goryo as this after partially making him into a half-gast to keep the heroes from targeting him. It works until Kiriko purges the worms out of Goryo's body.
  • Instant Armor: After he brings out the true strength of his Armor of Flies, it grants him this. However, it takes a good portion of his soul and changes his body further.
  • Killed Mid-Sentence: "Ark Forev—-"
  • Pocket Dimension: His armor allows this as whatever he absorbs sends it to a space between the human realm and the underworld.
  • Soul Jar: Hides his magic book within a pocket realm within himself that keeps him from harm. Once Roji manages to find and destroy it, it leaves him vulnerable enough for Muhyo to call in an envoy to finish him.
  • Taking You with Me: When he knew he was beat, he tried to kill Roji and Nana. Luckily Muhyo's envoy arrival prevents this.
  • Villainous Breakdown: After he runs out of magic, he tries to keep up his bravado but it's obvious he knows he's about to die and panicking. Especially when Pluto shows up to sentence him.

     Chiyo “Panza” Sakurai

A girl who can control people through touch. Also seems to have an obsession with Roji.

  • Ascend to a Higher Plane of Existence: After she redeems herself by saving Roji, she floats off to heaven.
  • Because You Were Nice to Me: The reason she's fixated on Roji as he was the only one nice to her when she arrived at MLS.
  • Cute Ghost Girl: She surprisingly doesn't look too bad as a half-gast.
  • Eerie Pale-Skinned Brunette: She certainly has the look of one.
  • No Ontological Inertia: Once her artifact is subdued, she starts to turn into a half-gast.
  • Parental Abandonment: Her parents didn't know how to deal with her seeing ghosts as she grew up. Once they had found out about MLS, they shipped her off and specifically told her to never come back.
  • People Puppets: How she goes about attacking Muhyo's group, by controlling the staff and residents of the hotel they're staying at through an artifact she has which can affect other people that she manages to touch directly or through those that she's controlling.
  • Redemption Equals Death: Though she dies, she redeems herself by protecting Roji and goes to Heaven as a result. In fact, she manages it through her own actions without any need for magical law, a rare feat.
  • Stalker with a Crush: To Yandere levels toward Roji.
  • Taking the Bullet: Blocks an attack from Mick meant for Roji.

     The Cortlaw Siblings

A trio of siblings who work with various type of spectral powers. They seek revenge against the MLS for the death of their parents.

Micheal "Mick" Cortlaw

The eldest sibling who wields a sword fused his body, allowing him to cut nearly anything.
  • Blade Below the Shoulder: Can turn any part of his body into a blade.
  • Blood Knight: He loves fighting and relishes any chance to cut something.
  • BFS: A major sword with a demon root as the hilt that can change properties as he sees fit. It's actually where his power lies. Once it's destroyed and the core exposed to sunlight, he dies.
  • Even Evil Has Standards: When they come to Ark and Buhpu asks to experiment on Kid in exchange for training in forbidden magical law, he and Ivy refuse until Kid voluntarily agrees to do it to help them.
  • Made of Iron: Quite literally since he's fused with his sword.
  • No Ontological Inertia: The Demon Root in his sword, once it's destroyed, his body crumbles to nothing.
  • Oh, Crap!: Gets this when Umekichi's Dragon Wheel plows right into and through his thrust, destroying his sword and the demon root along with it.
  • Red Baron: "Mick the Slasher".
  • Whip Sword: Can extend his sword to reach long range targets.

Ivy Cortlaw

Eldest daughter of the three, a ghost tamer.
  • An Ice Person: Two of her ghosts can inflict this on a person, as one unfortunate MLS student found out. It's certainly not Harmless Freezing either.
  • Disproportionate Retribution: One jerkass MLS student tries to hit on her, even though she initially ignores him. He gets scared off by two of her ghosts. She could've left well enough alone there and continued with her objective, but she instead has the ghost track the student to his dorm and kill him to make him into a ghost she could control.
  • Even Evil Has Standards: When they come to Ark and Buhpu asks to experiment on Kid in exchange for training in forbidden magical law, she and Mick refuse until Kid voluntarily agrees to do it to help them.
  • Green Thumb: One of her strongest attacks involve using vines to chase her targets. She tries to do this to Goryo and Ebisu via a combination of trapping the two in a house.
  • Impaled with Extreme Prejudice: How Buhpu kills her.
  • I Surrender, Suckers: Attempted twice and failed after Goryo depletes near all her power. The first time, Goryo's wise to her and has her bell eaten. When he gets in close, she tries to impale him with a stick. However, she misses his heart and only hits his arm, thus using up the last of her strength.
  • Red Baron: "Ghost Master Ivy".
  • This Cannot Be!: After Goryo and Ebisu manage to break out of her haunted house, she resorts summoning a major conglomeration of spirits her mom collected, citing it as the strongest ghost she has. Goryo's envoy quickly eats all of it, much to her shock.
  • You Have Failed Me: Has this pulled on her by Buhpu after Goryo defeats her.

Kid Cortlaw

The youngest of the siblings. A surprisingly giant individual who can change forms with the help of Buhpu.
  • Disability Superpower: In his lizard form, he's blind but his hearing is strengthened and he can hone in on any sound.
  • Fusion Dance: With Buhpu until he finds out he killed Ivy.
  • The Dog Bites Back: Once he finds out that Buhpu had manipulated him and killed Ivy, he quickly turns on and kills him.
  • People Puppets: On the receiving end, he has some control over his actions but Buhpu is the one who changes his forms.
  • Reluctant Warrior: It becomes obvious he follows along with his older siblings, but his heart certainly isn't with Ark's objectives and all he really wanted was just to live in peace with his siblings.
  • Together in Death: Takes comfort that he can be with his siblings again as he dies.
  • Unwitting Pawn: To Buhpu who was just trying to prep his body until he was ready to take it.


A short man who taught the Cortlaw siblings Forbidden Magical Law.

  • Beard of Evil: Has rather lengthy one that connects with his hair.
  • Dead Person Impersonation: Attempts this by using puppets of Mick and Ivy to keep Kid complacent. However, even Kid finds something off about them.
  • Evil Mentor: Was one to the Cortlaws, specifically Kid.
  • Grand Theft Me: Tries to pull it on Kid, he only hangs onto it for a few minutes until Kid kills him. As he dies, he reveals his true goal was to take over Enchu's body.
  • For the Evulz: He, along with Tomas, are the only two members without a Freudian Excuse. Buhpu is just evil to the core and completely power hungry.
  • Fusion Dance: Does one with Kid in a last-ditch effort. It works, at least until Yoichi reveals to Kid that Buhpu killed Ivy, at which point Kid turns on and kills him.
  • Hoist by His Own Petard: Turns out putting part of his power in an effigy and keeping it on his person wasn't the smartest idea when you're sharing the body of someone whose sibling you killed.
  • Manipulative Bastard: Toward the Cortlaws, he acted as a kindly if stern mentor figure but in reality, he was scheming to use them for his own ends.
  • Marionette Master: His main power, he uses puppets and effigies to attack his opponents. Kid himself is something of a main one that can change into different puppets at his command.
  • Near-Villain Victory: He manages to fuse with Kid, which kept him from hearing the rest of the Helsquitos's tale and immobilized Yoichi, Imai, and Ginji. But Yoichi throws a ward to where Kid's head is with the words "Buhpu Killed Ivy" written on the side. This leads to Kid turning on him.
  • Oh, Crap!: When Kiriko manages to summon Helsquitoes he panics as he knows they tell of one's darkest secret and will reveal to Kid that he killed Ivy.
  • The Starscream: Wasn't loyal at all to Teeki and his cause. He just wanted a body powerful enough to help him take over the organization.


An Ark research who is a seemingly normal being who doesn't have any powers, until he stops eating his lollipops.

  • Curse: Infused with a contagious curse which will spread if he doesn't keep eating lollipops
  • Reluctant Warrior: He isn't a fighter in the slightest and actually warns the heroes not to touch Muhyo while he's negotiating a contract with a powerful envoy. However, Teeki pretty much forces him to help him in trying to take them all out.
  • Screw This, I'm Outta Here!: Once Muhyo summons Hades, Teeki tries to get him to use a curse, but Julio refuses to even try to help him on that one.
  • Sweet Tooth: Always seen snacking on lollipops. This is due to the fact that it's the only thing keeping his curse in check.
  • Taking You with Me: How his curse works, it'll kill him but take out other people in the process.

  • Defeat Means Friendship: A variation, as Muhyo doesn't manage to defeat him but does impress him enough with his bravery that he allows him to be his envoy.
  • You Got Spunk: He's impressed by Muhyo's drive and that he managed to survive one of his major attacks that could've easily killed him. It's enough to offer Muhyo his contract.

A small fairy like being who appears when Muhyo is trying to contract Pluto, with her supposedly acting as a contract negotiator. Afterwards, she decides to hang around the heroes for a bit.
  • Lazy Bum: She basically decides to stay in the human world to avoid work.

  • Spanner in the Works: Twice:
    • Against Tomas, she is able to use her power to purge of the worms out of Goryo's body, reverting him back to normal and depriving Tomas of his Human Shield. She later saves Roji as he was diving into Tomas's pocket dimension to find his forbidden magic book.
    • Against Buhpu thanks to summoning her mosquitoes which tell a person's deepest darkest secret. Despite Buhpu's efforts they manage to get the full story out about him, which is enough to make Kid turn on him.

Prince of the Plutonian Sea and an envoy to Goryo.
  • Big Eater: Always asking if he can eat his targets and when Goryo allows it, he eats a whole mass of ghost in one fell swoop.

Other Ghosts and Spectres

     Face-Ripper Sophie 
The ghost of a young girl who can take the appearance of anyone whose face she has stolen.
  • Black Eyes of Evil: In the manga.
  • Cute Ghost Girl: Appearance-wise, yeah, she's one of the few normal looking ghosts of the series. But ability wise... not so cute.
  • Freudian Excuse: She was the youngest daughter of a socialite family, but her sister refused to let her come to any parties they threw as she felt she was an embarrassment. So Sophie killed her and took her face in response.
  • Face Stealer: If her title didn't give it away. This is what made her so dangerous despite her appearance.
  • I Just Wantto Be Beautiful: In life she was mistreated by her older sister who felt she was too ugly to be seen with their family. In death, her ghost is obsessed with being seen as cute.
  • Kids Are Cruel: She has the mindset of a ten-year-old, so likely she either doesn't know or care what she's doing.
  • Killer Rabbit: Has the appearance of a ten-year-old girl, but is one of the most dangerous ghosts around to the point that her grip can cause visible harm. It is the reason she was locked away in a solitary prison and that it took Muhyo summoning a high level envoy just to stop her.
  • Mind over Matter: Somewhat. She only displays this when Muhyo finishes her sentencing and chains her down before his envoy's arrival.
  • Red Eyes, Take Warning: In the anime, she sports these.
  • Pint-Sized Powerhouse: Despite her stature, she terrifyingly strong, to the point that her grip can rend flesh and she can burrow out of a sealed room. It takes summoning one of the strongest envoys of Hell just to stop her.
  • Soft-Spoken Sadist: Speaks in a very soft tone in the anime, barely even raising her tone.
  • The Unfavorite: In her family, which contributed to her Start of Darkness.
  • Voluntary Shapeshifting: Can do this once she has collected a victim's face and put it on.

A spirit that was locked away in the magic prison. However, he managed to stow away in one of the ghosts used for the practitioner exams and escape to wreak havoc.
  • Mind over Matter: Uses telekinesis, said to be even stronger then Sophie.
  • Oh, Crap!: Thinks the practitioners won't be able to harm him, only for Roji to get behind him and manage to seal him.
  • Poisonous Person: Uses poison to incapacitate his targets.

One of the demon kings.

The ghost of an arrogant MLS student that Ivy kills and brings under her control.
  • The Brute: His ghost form acts as one for Ivy.
  • Bullying a Dragon: When he sees Ivy, he tries to convince her to go with him when she clearly isn't interested. When he tries to forcefully insist, well... he comes to regret it.
  • Harmless Freezing: Nope. He's frozen alive by Ivy's ghosts and instantly dies.
  • Jerkass: In life he was certainly one, bullying Roji just for simply bumping into him and trying to get Ivy to go with him. That latter action costs him in his life.
  • Taking the Bullet: His ghost form manages to shield Ivy from Pakero's explosion attack, but he's destroyed in the process.

The ghost of a student that died during his studies and became trapped in a suit of armor.
  • Because You Were Nice to Me: Toward Roji, he literally sacrifices his existence for him as he was the only one who was really nice to him even though he tried to take his body.
  • Desperately Looking for a Purpose in Life: The main reason he wanted to be free from the armor, to get a second chance at life.
  • Friendless Background: Had no friends when he was alive and always considered himself a loser since he could barely keep up in his studies.
  • Drunk with Power: Goes into this when he gets his hands on the Writ of Passage, least until the Gingko Hag finds him.

  • Grand Theft Me: Tries to do this to Roji when he freed him from the armor.
  • Redemption Equals Death: He tries to take over Roji's body, but seeing he was the only one nice to him, he instead sacrifices himself to stall the Gingko Hag, allowing Roji to escape.
  • Small Role, Big Impact: He's only in the story for five chapters, but his role turns out to be very important as he manages to grab the Writ of Passage, the very thing both Muhyo's group and Ark are after, after Gingko Hag drops it. And since Roji befriends him, Muhyo's group manages to get their hands on it first, which in turn leads to Muhyo getting a powerful upgrade to his magical law book. Likewise, he's the one that directs Roji to the Dagger of Absolving, which is what he would later use to free Enchu from Teeki when he tries to take his body.

     Gingko Hag 
A ghost that was so strong it took ten practitioners just to seal her. However, she manages to escape when Ivy makes her move on the MLA.
  • Berserk Button: Losing her "boy", she pretty much goes on the warpath through the MLS trying to find it.
  • Companion Cube: Treats the Writ of Passage as "her boy".
  • Freudian Excuse: In life, she was a young woman whose boyfriend went off to war. He died and she took her own life after learning about it. The reason she's so obsessed with the Writ (which was given to her by Isabi) is because she's obsessed with beautiful things.
  • Sealed Evil in a Can: Was buried beneath the city where MLA stood since they couldn't get rid of her at the time. It wasn't deep enough however.
  • Taken for Granite: Has the power to turn people to stone.

  • Wicked Witch: Looks and acts the part.

     Okada Yuki 
The ghost of a bullied middle schooler who took his life.

  • Driven to Suicide: Took his own life when he realized his so called "friends" pulled a cruel prank on him by giving him fake addresses when they left middle school as an "apology".
  • The Faceless: His initial form is nothing but a face and a mouth when he's not imitating someone.
  • I Just Want to Have Friends: Poor guy just wanted to be accepted for who he is, but no one could get past his looks and mocked him for it.
  • School Bullying Is Harmless: Subverted, it affected Okada heavily when he left for high school. Especially since an entire class pulled a massively dickish prank on him.
  • Voluntary Shapeshifting: Once he captures someone, he can take their form.

A half human half ghost that was left in the wild. While he tried to avoid killing, he decided to try to find a way to make more of his kind.
  • Batman Gambit: Waited until MLA executioners made a barrier to try and trap him then used his roots to take their tempering so that he could use it to revive Kuguri.
  • Half-Human Hybrid: A half human, half ghost.
  • I Just Want to Have Friends: What he claims anyway, but his definition of "friends" is to try and eat them, especially if they have a lot of power (like Muhyo and Roji).
  • Karma Houdini: Defeated by Muhyo but wasn't destroyed (though majorly de-powered) and still at large. The manga ended before his story could reach a resolution.
  • Parental Abandonment: Abandoned by his mother since everywhere they traveled, they were always shunned. She did leave some encouraging words for him to endure the hardships that were to follow.


  • The Dreaded: It was kept away and in stasis for the most part, but the MLA are afraid that Vector will re-awaken it. Unfortunately, they're right, and their attempts to stop it only help aid Vector in reviving it.
  • Sealed Evil in a Can: Sealed away beneath the North Branch of MLS.

How well does it match the trope?
