Set in a dystopian future filled with criminals, Akane Tsunemori is tasked with solving crimes via Division One of the Public Safety Bureau’s Criminal Investigation Division.

Criminal justice is mainly achieved via the Sibyl System, which uses a range of biomechatronic techniques to measure the biometrics of Japanese citizens’ brains and mentalities at all times.

This assessment, known as a Psycho-Pass, then opens the citizen up to targeting by the police due to their propensity to commit a crime or suspected of committing a crime.

The exploration of these societal and psychological aspects particularly around dissent and thoughtcrime, much in the vein of the film Minority Report, is strong throughout the series.

A stylization of gothic, Gosick is set in a fictional European country in the early 1900s, revolving around a genius girl and her brother who is a detective. He relies on her penetrating logic to solve seemingly unsolvable mysteries.

Kazuya Kujo is a Japanese exchange student who becomes involved with the brilliant Victorique de Blois, although doesn’t quite measure up to her abilities.

Thematically, there is a mysterious and elegant atmosphere that pervades the dreary European scenery, with dark and foreboding colors featuring heavily. Most viewers of a detective based anime are going to want an involved plotline, and Gosick does not disappoint.

Ghost Hunt

A detective show focusing around the investigation of occult and other unexplainable phenomena across Japan, the series focuses on a specialist team of spiritualists and other experts tasked with looking into the strange occurrences.

Mai Taniyama is in the lead role and is a first-year high school student who joins the Shibuya Psychic Research due to destroying one of their cameras during an investigation, although  it turns out that Mai has ESP abilities, as well as premonition dreams and clairvoyance.

The show has been praised for its uniquely Japanese take on the ghost hunting and paranormal adventure genre, introducing many aspects of Japanese mythology and folk tales.

An interesting take on the detective genre, Daisuke Kambe comes from a very wealthy family and is a detective who is not above giving out the occasional bribe if it helps him get the job done.

He is partnered with Haru Kato, who strongly disapproves of Kambe’s methods. The series also has a strong sci-fi element with the introduction of many gadgets and crime fighting computers. It is also not shy on action sequences that can really get the heart pumping.

However this is not some campy, paint by numbers show. There are many surprising twists and turns as well as mystery cloaking every episode. Definitely one to watch if you’re looking for a refreshing take on the genre.

Similar to the above previewed Ghost Hunt, the show focuses heavily on the human relationships and trouble they face, particularly as the backstory of Saitou is revealed.

The series has been praised for dealing with the themes of grief and confusion combined with self-condemnation and thoughts of impotence that can arise after a death.

The time travel element at the effects of actions on timelines is very nonlinear, contributing to a buildup in suspense, as one never knows where the narrative is going.

Ryoko Yakushiji is a top police officer, working in the Tokyo Metropolitan Police Department. Tasked with investigating bizarre cases or seemingly unexplainable phenomena that can’t be solved with traditional police techniques, sometimes working with private security firms.

A highlight is the understated yet eclectic score for the series, and it is also unique for tackling social issues found in Japan such as hikkikomori and bullying.

Loki guesses rightly that this is the best way to encounter evil, meaning he can vanquish it for the auras he needs to be readmitted by Odin.

Many appearances by other Norse gods abound, however the series is often lauded for its emotional scenes and high octane battle scenes.

Himitsu — Top Secret

Bez naslova 1200 × 675 piks. 49

Another futuristic mystery series, this series follows the investigators of the National Research Institute of Police Science’s 9th Forensics Laboratory as they use a brain scanning technology that can search the memories of people.
