Shingeki No Kyojin: Plot, Characters And Seasons

Shingeki no Kyojin (also known as Attack on Titan  in English and Attack on the Titans in Spanish) is a manga written and produced by Hajime Isayama. This manga was later adapted into an anime series bearing the same name.

The story revolves around Eren Jaeger and his friends, Mikasa Ackerman and Armin Arlet, who live in a world where they suffer the attacks of the titans, beings of great height (3 to 15 meters approximately), whose sole objective is to devour the humans.

Due to this, humanity was forced to enclose itself in a series of walls to protect itself from these attacks. However, after a strong attack by the Colossal Titan, Eren, Mikasa and Armin decide to enlist in the army to fight these creatures.

The manga was published in 2009 and, thanks to its popularity, an anime adaptation was made in 2013. Likewise, a movie, several spin-offs and even several video games have been made.


The premise of the story starts from the near extinction of humanity thanks to a series of sinister creatures of great size called titans, which have a similar appearance to those of humans (but do not have sexual organs) and that seem to emerge from the nothing for the sole purpose of devouring people.

For its protection and preservation, a series of walls of about 50 meters was built to protect the few survivors. These walls are: MarĂ­a (it is the largest and contains a large part of humanity), Rose and Sina.

For a century life remained calm and peaceful, until the surprising appearance of the Colossal Titan, a creature of more than 60 meters high that destroyed a part of the wall in the Shiganshina district (place where Eren lived with his friends), originating the entrance from other titans into the Maria wall.

Next to him was also the Armored Titan, whose body structure and strength allowed another section of the wall to rupture. This caused the evacuation of those who were between the walls Maria and Rose.

The Titans caused chaos and destruction in their wake. Thousands of people died, even Eren’s mother was eaten by a titan. From that moment on, Eren vowed to exact revenge on the Titans.

Important facts

It is worth highlighting a series of information that is vital to understand the story:

-Titans have a height of 3 to 15 meters. However, this was denied thanks to the appearance of the Colossal Titan, which reaches 60 meters.

-There are differences between manga and anime. In the manga it is explained that Ymir Fritz discovered a vital power by which he originated the Titans. Thus his family became the royal blood and the important group for humanity. Instead, the anime first shows the destruction capacity of the Titans and the chaos produced in their wake.

-Titans have similar characteristics to humans, since they are bipedal beings, with the same number of members and with similar bodily functions. However, a notable difference is the lack of sexual organs, so it is unknown if they are capable of reproducing in any other way.

-These creatures don’t really need food, but they still devour human beings almost compulsively. In addition, they can remain inactive if they do not receive sunlight .
