“Devils’ Line” is a police procedural wrapped in a vampire conspiracy, and it mostly earns the reputation that comes with it. The 2018 anime series, based on Ryo Hanada’s manga, follows Yūki Anzai, a half-vampire detective tasked with cracking down on vampire crimes in modern-day Tokyo. The setup sounds simple: a man who hunts monsters for a living falls for a woman who might be one of them. The execution is messier, but it lands often enough to justify the twelve episodes.
The show airs on AT-X, Tokyo MX, BS11, Sun TV, and KBS Kyoto, and it runs from April 7, 2018, to June 23, 2018. Twelve episodes is a tight window, and the series uses it to build a conspiracy involving the CCC, an organization that wants to eliminate vampires entirely. That tension between hunting and protecting is the engine that drives the whole thing.

Anzai’s Rule
Anzai is the anchor of the show. He is a half-vampire on his paternal side, working as part of the Metropolitan Police Department’s Public Safety Division 5. His job is to crack down on vampire crimes, but his personal rule is stricter: he never drinks human blood. That rule is tested almost immediately when he meets Tsukasa Taira, a graduate student who gets attacked by a vampire and is saved by Anzai.
Yoshitsugu Matsuoka voices Anzai in Japanese, while Adam Gibbs handles the English dub. The character is built on a contradiction. He is a hunter who refuses to treat his prey as prey, and that tension is what makes him watchable. He fears losing control around Tsukasa, and that fear is the emotional spine of the series.
Tsukasa is the other half of the central pair. She is a graduate student who survives an attack by a vampire and finds herself drawn to Anzai. Yui Ishikawa voices her in Japanese, with Luci Christian on the English dub. Their relationship grows fast, but it is not a romance that gets resolved by episode three. The show keeps the bond tentative, which helps sustain the drama across the full run.
The CCC Conspiracy
The CCC is the big bad of the series, and its goal is simple: eliminate vampires entirely. Anzai works against it, but the organization operates in secret, and its machinations drive the plot forward. The show spends time building out the group’s methods, and the mystery around its leader keeps viewers guessing about who is pulling the strings.
Hans Lee, voiced by Ryōhei Kimura, is part of Anzai’s team. Takashi Sawazaki, voiced by Yoshimasa Hosoya, is another member of Division 5. The supporting cast fills out the police side of the story, giving Anzai colleagues who understand his world even when they do not agree with his choices.
Juliana Lloyd, voiced by Miyuki Sawashiro, and Kirio Kikuhara, voiced by Takahiro Sakurai, round out the main group. Lloyd is a vampire who knows the politics of the criminal underworld, and Kikuhara brings a sharp edge to the team. Both characters add texture to the action sequences, which are frequent and well-choreographed.
Takeshi Makimura, voiced by Hiroshi Kamiya, and Nanako Tenjō, voiced by Nao Tōyama, also appear regularly. Makimura is a detective with a sharp eye for evidence, and Tenjō brings a quieter, more reserved presence to the mix. The show uses these characters to give Anzai a range of perspectives, from the analytical to the emotional.
Kenichi Yoshii, voiced by Shouta Aoi, and Yōsuke Asami, voiced by Kazuyuki Okitsu, appear as recurring figures. Naoya Ushio, voiced by Ryōta Ōsaka, Megumi Ishimaru, voiced by Akira Ishida, Midori Anzai, voiced by Mayumi Asano, and Tamaki Anzai, voiced by Mamoru Miyano, also show up. Ryūsei Yanagi, voiced by Satoshi Hino, and Ryūnosuke Katagiri, voiced by Daisuke Hirakawa, complete the ensemble. The sheer number of named characters means the show cannot spend equal time on everyone, but it does a solid job of making each person feel distinct.
What Works
The pacing is the show’s biggest strength. Twelve episodes is a short stretch for a conspiracy this complex, and the writers do not waste time on filler. Each episode moves the plot forward, whether through a new clue, a confrontation, or a twist that changes the direction of the investigation. The result is a tight, focused story that holds attention from start to finish.
The animation is competent without being flashy. The series leans on solid character designs and clear action choreography, and the backgrounds are detailed enough to sell the modern Tokyo setting. Nothing here demands a second viewing purely on visual merit, but the show looks professional throughout.
The voice acting is uniformly strong. Matsuoka and Ishikawa carry the lead roles with conviction, and the rest of the cast delivers consistent performances. The English dub, with Gibbs and Christian leading the cast, is a faithful match to the original.
What Falls Short
The show’s biggest weakness is its handling of the romance. The attraction between Anzai and Tsukasa is genuine, but the resolution feels rushed. The series spends significant time building tension between them, only to resolve it in a way that feels convenient rather than earned. This is a common problem in shows where the lead characters are kept apart for dramatic purposes, and “Devils’ Line” does not escape it.
The CCC is also vague. Its methods are shown, but its motives remain unclear for much of the series. The show introduces the organization early and keeps it in the background until the final stretch, which leaves viewers wanting more information about why it exists and who runs it.
Ranking the Episodes
Here is how the twelve episodes break down:
- The pilot sets up the rules and introduces the central couple.
- The second episode deepens the relationship and introduces the CCC threat.
- Episodes three through six build the conspiracy and establish the supporting cast.
- Episodes seven through ten push the plot forward with twists.
- The penultimate episode raises the stakes.
- The finale wraps everything up.
The middle stretch drags slightly. Episodes five through eight are competent but similar in tone, and the pacing slows during this period. The show recovers in the back half, where the twists and the climax pick up the energy again.
Final Word
“Devils’ Line” is a solid, if uneven, entry in the genre. It takes a familiar premise and gives it a fresh angle by focusing on a hunter who refuses to treat his quarry as prey. The romance sags in the back half, and the conspiracy could have used more depth, but the core of the show — the relationship between Anzai and Tsukasa — is strong enough to carry the series through its flaws.
The anime adaptation, produced by Platinum Vision, captures the tone of Hanada’s manga well. The series does not reinvent the wheel, but it does not need to. It executes its plan with confidence, and that confidence is reflected in the final product.
