Synopsis

Haunted by an unwelcome possession, or dealing with a ghost that refuses to move on? Muhyo & Roji’s Bureau of Supernatural Investigation follows Muhyo and Roji, specialists in magic law who take on cases involving the spirit world.

With their expertise, they deliver judgments on troublesome apparitions—sending them onward or condemning them to harsher fates—bringing a firm sense of justice to the supernatural.

Otaku Consensus

Muhyo & Roji's Bureau of Supernatural Investigation lands as a sturdy, niche supernatural shounen: Nobuhiro Kondou's direction and Yasuyuki Suzuki's series composition keep the 12-episode run cleanly paced, and reviewers repeatedly praised it as an unusually effective adaptation of Yoshiyuki Nishi's manga. Its strongest material is the compact case-driven first season, supported by smooth Studio Deen movement and voice acting that gives weight to otherwise restrained visuals. The main criticism is just as consistent: the series is straightforward rather than intricate, with little visual flash and at least one recurring character gag that rubbed some viewers the wrong way.

Why You Should Watch

Watch this if you want supernatural shounen with rules, offices, and consequences instead of free-form monster fights. It scratches a procedural itch closer to early Yu Yu Hakusho's spirit-world bureaucracy than Jujutsu Kaisen's high-impact combat spectacle, while leaning darker and more judgmental than Natsume's Book of Friends. The appeal is in the compact 12-episode shape: cases move quickly, the mythology is easy to track, and the adaptation does not drown its horror-tinged ideas in tournament escalation. Studio Deen's animation is not a sakuga showcase, but reviewers noted that it stays smooth where it counts, and the Japanese cast, especially Ayumu Murase, gives the material a sharper emotional edge. If you want ghost stories with shounen structure and minimal padding, this is a practical pick.

Key Characters

J
Jirou Kusano(VA: Yuu Hayashi)
Roji functions as the more openly human half of the lead duo, giving Yuu Hayashi room to play anxiety, loyalty, and moral discomfort against the series' colder supernatural rules.
T
Tooru Muhyou(VA: Ayumu Murase)
Muhyo is the title's severe center of gravity, and Ayumu Murase's performance was singled out in early reactions for adding emotional depth and bite to scenes that could otherwise feel visually static.
N
Nana Takenouchi(VA: Iori Nomizu)
Nana stands out in a show tagged as having a primarily male cast, giving the main lineup a civilian-facing perspective rather than leaving every scene inside the specialists' partnership.

What Makes It Stand Out

1
Studio Deen produced the 12-episode first season, which aired from August 3 to October 19, 2018; its compact length is a major reason the adaptation feels direct rather than padded.
2
Reviews consistently describe the animation as smooth and movement-focused rather than showy, a useful fit for a supernatural mystery series that depends more on timing and atmosphere than constant spectacle.
3
The Japanese voice cast received specific praise for giving emotional weight to restrained visuals, with Ayumu Murase's work as Muhyo called out in first-impression coverage.
4
The anime adapts material from Yoshiyuki Nishi's 18-volume manga and was praised online for being straightforward but notably effective at transferring the source's story to television.
5
The visual pipeline had unusual role concentration: Kenichi Tajiri served as both art director and art designer, while Ayako Kurome handled both color design and director of photography duties.

Fun Facts & Trivia

Fun fact 1: The original creator is Yoshiyuki Nishi, and the source manga ran for a modest but substantial 18 volumes before receiving this 2018 TV adaptation.
Fun fact 2: The show's genre profile differs slightly by database: MAL lists it under Mystery and Supernatural with a Mythology theme, while AniList's strongest tags include Shounen, Ghost, Male Protagonist, and Demons.
Fun fact 3: Ayako Kurome is credited in two key visual-control roles, color design and director of photography, meaning the same staffer helped define both the palette and the final composited look.
Fun fact 4: Kenichi Tajiri also held dual art responsibilities as art director and art designer, with Miyoshi Makiya additionally credited for art design.
Fun fact 5: Its reception sits in the middle of the supernatural shounen pack: MAL records a 6.71 score from 15,396 votes, while AniList lists a 63/100 score and 118 favourites.
