Muhyo & Roji's Bureau of Supernatural Investigation (Japanese: ムヒョとロージーの魔法律相談事務所, Hepburn: Muhyo to Rōjī no Mahōritsu Sōdan Jimusho), also known as simply Muhyo & Roji, is a manga series by Yoshiyuki Nishi. The series premiered in Japan in Weekly Shōnen Jump in December 2004, and ran until its conclusion in March 2008. It follows a young genius Magical Law Executor, Toru Muhyo and his assistant, Jiro Kusano as they track and find ghosts, then send the spirits to heaven or hell depending on the account of their lives in his magical law book. The individual chapters of the series were collected and published in 18 tankōbon volumes by Shueisha.

The series is licensed for an English language release in North America by Viz Media, which released the first volume of the series in October 2007 under its "Shonen Jump" manga line.

An anime television series adaptation by Studio Deen ran from August 3, 2018 to October 19, 2018 on SKY PerfecTV! and Animax. A second season has been announced.


Toru Muhyo (六氷 透, Muhyō Tōru, ムヒョ Muhyo)
Voiced by: Ayumu Murase[4]
It's said to be the youngest executor graduated from the Magical Law School. Muhyo paired up with Roji and the two formed their own business of exorcising ghosts. Muhyo has a somewhat emotionless personality, showing no sign of pity when dispensing of the ghosts. He seems to be sleeping most of the time (for as an executor of the Laws, large amount of spiritual energy is needed for him to summon the necessary Hellish being to carry out the sentences of various ghosts, spirits). He tries to show no signs of caring for his assistant, Roji, but it immediately becomes evident that he does during dangerous situations, or when one of Muhyo's friends or acquaintances points it out. He is often rude to other people, and keeps a stern face, but deep down, he has a strong sense of Justice. He is also extremely powerful, being able to perform a judgment that normally requires four top-notch executors by himself. Despite Enchu's vile attacks upon him and those he cares for, he still wished to redeem him. Muhyo has shown that he can speak the language of the underworld allowing him to speak with the creatures he summons to carry out his sentences, this talent also allows him to command the creatures to pause or stop the punishment they were delivering.
Jiro Kusano (草野 次郎, Kusano Jirō), nicknamed Roji (ロージー, Rōjī)
Voiced by: Yū Hayashi[4]
He is Muhyo's assistant. He's a kind-hearted person, almost to a fault, as it interferes with his ability to exorcise ghosts with a sob story. He is a bit of a whiner and a crybaby. However, he is adept at writing seals to hold back ghosts while Muhyo sentences them. He is knowledgeable on types of ghosts, but has nearly no knowledge on exorcism of ghosts and how to use the laws of magic. He initially feels that Muhyo is rude, mean, and hates him. But as the series progresses, he finds out that Muhyo chose him to be his apprentice even though the normal standard is to choose someone who is the rank of an assistant judge and Muhyo actually deeply cares for him. His power often seemingly fluctuates between strong and weak, becoming stronger when he has more confidence in himself. He was frustrated that Muhyo didn't ever instruct him. In a flashback showcasing how Roji met Muhyo, it was revealed that Roji wanted to learn Magic Law after a friend was possessed and an executor, specifically Page, showed up and saved him; Roji also successfully used an item only an assistant judge could handle. During the Magic Law Examination, it is revealed that he has an extraordinarily high tempering (ren). Roji is definitely more feminine, which causes comedic scenes to emerge sometimes.
Kenji Satou (佐藤 健二, Satō Kenji) / Kenji (ケンジ)
Voiced by: Kōhei Amasaki[5]
A trouble-making boy who had believed Muhyo and Roji's business was a sham and wrecked their sign. He did not believe in ghosts until the pair saved him from a blood-drinking ghost he had accidentally freed. Afterwards, Kenji grew a liking for the pair, often referring to Roji as "Bean Sprout" and Muhyo as "Onion". He always tries to find excuses to hang around their office, as Muhyo has made it a rule never to meet a client after the case is complete unless they bring a new one.
Nana Takenouchi (竹乃内 菜々, Takenouchi Nana) / Nana (ナナ)
Voiced by: Iori Nomizu[6]
A photographer who Kenji introduces to the duo. Her late father had made a living producing fake ghost pictures, causing a rift between the two. Nana becomes another of Muhyo and Roji's regular clients after Muhyo sends her father's troubled spirit to the River Styx for purification so he can go to heaven. She is notably well endowed which often causes her to be the target of perverts. It is later revealed that she is a spirit medium.
Yoichi Himukai (火向 洋一, Himukai Yōichi) / Yoichi (ヨイチ)
Voiced by: Tetsuya Kakihara[4]
A judge and a childhood friend of Muhyo's. He is a pervert who enjoys trying to guess girls' cup sizes (his first appearance was him squeezing Nana's breasts). Yoichi appears to have a crush on Nana, which is unfortunate, since she considers him a creep. However, underneath this exterior resides his experience and wisdom that rival Muhyo's. Yoichi had offered to be Muhyo's partner, but Muhyo had already chosen Roji instead. He's an expert at every type of Magical Law except for Execution.
Soratsugu Madoka (円 宙継, Madoka Soratsugu), also called Enchu (エンチュー, Enchū)
Voiced by: Hiroshi Kamiya[4]
He was a childhood friend of Muhyo and Yoichi. Unlike Muhyo, he was studious and serious about Magic Law. Enchu had wanted to be an Executor so he could support his family, including his sick mother. Enchu spent hours everyday studying, with his friends not noticing. One day, Muhyo's talent "woke up", which overtook Enchu and created a desire within him to surpass Muhyo. When Muhyo and Enchu were both up for becoming Executor, Enchu had left because he had learned his mother had died. When he had returned, Muhyo had been promoted to Executor, causing Enchu to break down mentally. He has shown to have some control over ghosts and other spirits through his knowledge of Forbidden Magic Law. He has also apparently become inhuman as at one point he generated ten forearms on a single arm. Despite his grudge, Enchu still cares for others, claiming its better to practice Forbidden Magic Law with friends and retreating in order to save Rio who was Ghosting. Eventually, Enchu was "saved" from his madness, realizing that his friends never stopped caring about him despite what he put them through. This realization did not keep him from punishment, however, as afterwards, he was sentenced to the Arcanum for an indefinite amount of time.
Yu Abiko (我孫子 優, Abiko Yū), also known as Biko (ビコ)
Voiced by: Rie Kawamura[6]
She is a Magic Tool Artificer, who is able to make magical tools, but cannot use them herself. She is deeply devoted to her teacher, Rio, and was shocked by the revelation that she was a traitor. When she was younger, she disliked Rio until Rio saved her from an experiment gone wrong. Roji first believed she was a boy when she first appeared. She has three apprentices of her own. She hoped that Rio could be saved, and wished to go raspberry picking with her. After the battle had ended, Biko and Rio lived together since Rio had been sentenced to imprisonment within their home.
Rio Kurotori
Voiced by: Satomi Akesaka[6]
Biko's teacher and a skilled Artificer. While she initially seemed to help Muhyo and Roji, she was actually working with Enchu, having grown bitter after no one helped save her mother from an evil spirit. Despite having become a traitor, she was still fond of Biko, but believed that it was too late to go back. When her mother was alive, Rio had to resort to low means in order to make money so that she could take care of her mother. When a spirit attacked her mother, she frantically sought help but was turned down by the executors in her neighborhood. It was revealed that Teeki had intentionally caused the attack on her mother in an attempt to gain Rio as a pawn. When she discovered this, she tried to deny it, then denied that she was able to be saved at all, but soon came to terms with her situation and did her best to turn things around. She lives with Biko, sentenced to imprisonment within their home. According to Muhyo, she is a "kissing fiend", which is an accurate statement.
Face-Ripper Sophie / Sophie (ソフィー)
Voiced by: Yūko Gotō
An extremely powerful ghost who was once imprisoned in the Arcanum, but released by Rio. In life, she was kept away from parties by her older sister due to her being considered "plain", and killed people for their faces because she wanted people to think she was pretty. As a ghost, she was able to shapeshift and assume other people's forms. Muhyo used a high-level magical commandment to sentence her for her crimes. As she faded she cried and stated, "Sister, why can't I go to the party?". She was a very powerful ghost as it took the usage of an envoy that normally requires four executors to summon to defeat her.
Reiko Imai (今井 玲子, Imai Reiko)
Voiced by: Mitsuki Saiga[6]
A judge of Magic Law. She was assigned to be a guard for the Arcanum, a prison for powerful ghosts including Sophie. When Rio freed Sophie, she nearly became a victim but was spared because Sophie considered her face ugly. She was also nearly strangled by Teeki, but luckily escaped. Since the Arcanum incident, she has become friends with Jiro and escorted him to the Magic Law Academy. In chapter 155, it is revealed that Imai possibly has feelings for Roji.
Teeki the Fallen
Voiced by: Tetsuharu Ōta[5]
He was Enchu's right-hand man and a powerful but mysterious foe to Muhyo and Roji. The association had marked him for 800 years or so. He 'meddled' in magic law and when he was finished, he disappeared into thin air. It was unclear what Teeki was; a ghost or a practitioner turned immortal by forbidden law. Teeki was also the one responsible for the fire inside the Arcanum after Rio followed Muhyo and company out into the forest. He seemed to like to killing and destruction, as he laughed at Mr. Maeda when he set the Arcanum ablaze and wanted to kill Muhyo's group instead of retreating. He was the one to introduce Enchu to Forbidden Magic Law. Teeki wore a four-eyed mask and gloves that had the mark of Forbidden Magic Law on them.
Page Klaus (ペイジ・クラウス, Peiji Kurausu)
Voiced by: Wataru Hatano[6]
The teacher of Muhyo and Enchu, he is very famous within the association. He believes that Magic Law starts with physical fitness. He likes to compose poetry and thinks he's good at it; he also acts as a father to his students (ex. Rushing to Muhyo when he was supposed to be healing, out of relief that he was okay). Although Roji is unaware of it, Page was the practitioner that exorcised a ghost from a friend of his and gave him his tie. He claims that Muhyo and Roji were destined to meet.
Daranimaru Goryo (五嶺 陀羅尼丸, Goryō Daranimaru) / Goryo (ゴリョー, Goryō)
An executor of magic law like Muhyo, and head of the centuries-old Goryo Group Syndicate. While the Goryo group are not particularly strong in magic law, they make up for it with cunning use of strategy; in addition, they perform extremely vicious practices ranging from bribery to murder. Goryo was a jerk who only cared about money and his family's pride, threatening to release ghosts he had exorcised if clients do not pay him, and treating his assistants like trash and discarding them should they fail him. But after the Goryo Group is destroyed by Ark and he is rescued from Tomas, he becomes a better person.
Hanao Ebisu (恵比寿 花夫) / Ebisu (エビス)
A judge of Magic Law who worked for Goryo as an assistant. He looks like a clown and is afraid of Goryo's wrath. He was jealous of Roji because Roji was only a clerk who was practically given his current job, with Muhyo no less, while Ebisu had to claw his way to where he is now. He helps Goryo in banishing ghosts and running his company. After Goryo and Muhyo's competition, he was fired by Goryo for failing him in a strategy. Despite that, he is the first to run to Goryo's aid when the Group is attacked.
An evil practitioner working for "Ark". He was once a teacher and Page's friend, but it was revealed that he faked his credentials and was wanted for several crimes. He had an obsession for collecting, anything from teacups to souls, because he paired up with Beelzebub.
Chiyo Sakurai (桜井 千代, Sakurai Chiyo), also called Panza (パンジャ, Panja)
She was a ghost assassin working for the Forbidden Magic Law group known as "Ark", working directly under Teeki. She was a powerful spirit with an overwhelming obsession with Roji, and because of this uses her powers of human puppetry to try and kill off Muhyo and kidnap Roji. It was revealed that she always got bullied because she could see ghosts and she wished her knight in shining armor would come and save her. Even her parents forced her out of their house by making her take the exam to become Muhyo's assistant and telling her not to come home. She lost her applicant form on the way and no one wanted to help her except for Roji, who gave her one of his applicant forms. That was when Chiyo fell in love with him. Unfortunately, she met Teeki and was misled by him into using forbidden law. On her way to heaven, Roji told her that he wished he had known her feelings so they could have been friends, but she said she preferred him as her knight. Her passing was the spark of determination within the group to end Enchu and Teeki's terrorization.
Mick Cortlaw
A swordsman known as 'Mick the Slasher' who worked for "Ark". However, he had a tendency to do what he wanted, and followed orders in his own straightforward style. Unlike many other Ark members, he was very simple-minded and had no long-term goals other than to move on to the next fight. Seemingly relaxed and casual, he could become rather eccentric in battle, using his whole body as a morphing sword. His parents were evil practitioners who were killed by the MLA after they attacked representatives bearing a treaty.
Ivy Cortlaw
A ghostmaster who worked for "Ark". She bore a grudge towards MLA for the death of her parents and tried to destroy the MLA, but was stopped by Goryo, then murdered by Buhpu.
