The 15 Best Seinen Anime

The Seinen anime (which in Japanese means “grown man”) is a type of anime intended generally to male persons over 18 years, usually between 20 and 40 average. The seinen animes often address complex issues and dilemmas in real adult life, which makes them totally unsuitable for children. In addition, they are also plagued by scenes with erotic content and physical and psychological violence.

In the near future, it is possible to instantly measure the mental state of a person, the personality and the probability that said person will commit crimes thanks to a psycho-somatic scanner that performs a scan of the functions of the brain and other biological and chemical functions of the body, determining the Psycho-Pass, a number associated with a color in each person. When this probability, measured as the “Crime Coefficient” index, is too high, that is, it has a very dark color and a very high number, individuals are persecuted and detained with lethal force, if necessary. This task is performed by a special team of potential criminals called Executors, who are supervised by police officers known as Inspectors. Inspectors must ensure that the executors in exercise perform their duties within the limits of the law. Executors and inspectors employ special weapons called “domineers” designed to fire only at those with a higher than normal crime rate.

The story follows a Unit of the Division of the Office of Public Security and Criminal Investigation, the equivalent to the police of the current time, directly responsible and administrator of the work of Inspectors and Executors.

In Psycho-Pass the philosophical issue is treated very often, from the perspective of the main antagonist as from the same system that governs society.

Many people consider manga far superior to anime (and rightly so), but Berserk could not be left out of a list with the main Seinen titles .

Berserk is based on the manga written and illustrated by Kentaro Miur, belonging to the epic-fantastic genre. Set in a dark fantasy world inspired by medieval Europe, the story focuses on the characters of Guts, an orphan and solitary mercenary, and Griffith, the leader of a mercenary band called The Gang of the Falcon (or Falcons ).

The series focuses on Kimihiro Watanuki, a young student who is tormented by ghosts (known by ayakashi ). One day, he meets Yuuko Ichihara’s shop, a witch who grants wishes. She tells Watanuki that she can fulfill her wish, but only if she is willing to exchange something of equal value. Watanuki agrees, but Yuuko informs him that the value is too large, and that he must pay the debt working in his shop.

A characteristic of the CLAMP is to create relationships between their works and link the different fictional universes of some of their previous works. That is why there is a clear connection between xxxHOLIC and Tsubasa: RESERVE CHRoNiCLE . In fact, the presence of characters from one anime in another is common.

Cowboy Bebop

Best Seinen Anime

The story focuses on a group of bounty hunters (Spike, Jet, Valentine, Ed and Ein) who travel through the space in the Bebop spacecraft in search of and capture dangerous criminals. The anime touches on philosophical themes, such as loneliness, existentialism, emptiness and the influences of the past.

There are many reasons to watch this anime: soundtrack, well-built characters, exciting plot and overwhelming visual aspect. The series became a commercial and critical success worldwide, being considered as a masterpiece in both the Japanese and international markets (especially in the United States).

Samurai Champloo

Best Seinen Anime

We are witnessing the trip of Fuu, a 15-year-old girl who looks for the “samurai that smells like sunflowers.” Accompanying him, there are Mugen (reckless and rake) and Jin (calm and stoic), a swordsman and a ronin , respectively, who help the girl as a way to pay a lost bet.

Shamurai Champloo is officially classified as a shōnen , but like Cowboy Bebop , it deals with issues and situations that are not very appropriate for the youngest: moments such as marijuana plantation, slave prostitutes, various combat scenes (very bloodthirsty) and the tragedies that show how life is not made of happy endings like in the movies.

Death Note 

Best Seinen Anime

There is great controversy about the demographic classification of Death Note . The manga was originally published by Weekly Shōnen Jump , a magazine specialized in stories for young teenagers, but it is undeniable that the complexity of its plot is more in line with the basic characteristics of a seinen.

The manga series is written by Tsugumi Ōba and illustrated by Takeshi Obata, and the anime adaptation was directed by Tetsurō Araki. It also has several movies and video games.

All the intellectual conflict between L and Kira (Light Yagami), the absence of a predominant hero in history and all the complexity and gravity of the plot are more than attractive elements for adults (at least in the West). As a curiosity, the series was banned in China because the children modified their notebooks to resemble the Death Note.

Death Note is one of the most acclaimed titles in the world of anime and manga , being considered a true masterpiece.

The anime is entirely available on Netflix, which also produced a real action movie in 2017, directed by Adam Wingard and with very mixed (predominantly negative) reviews because of the changes from the original version
