what is the story behind attack on titan
Attack on Titan Attack on Titan (Japanese: 進撃の巨人, Hepburn: Shingeki no Kyojin, lit. "Advancing Giant") is a Japanese manga series written and illustrated by Hajime Isayama. The series began in Kodansha's Bessatsu Shōnen Magazine on September 9, 2009, and has been collected into 26 tankōbon volumes as of August 2018. It is set in a world where humanity lives in cities surrounded by enormous walls protecting the humans from gigantic humanoids that are referred to as titans. The titans vary in height and endlessly eat humans seemingly without reason. The story initially centers on Eren Yeager and his childhood friends Mikasa Ackerman and Armin Arlert, who join the military to fight the titans after their hometown is invaded and a titan eats Eren's mother, whom he swears to avenge. As the story progresses and the truths about the titans are slowly revealed to the reader, the narrative shifts to encompass Historia Reiss, squad leader Levi, Eren's father Grisha, and other supporting characters.
Attack on Titan It is later revealed that the Titans were created when Ymir Fritz found the "source of all organic life" and became the Founding Titan where she had the ability to create and control the Titans. When Ymir Fritz died as a side effect of having the Titan ability for 13 years, her soul was split into the 9 Titans where their abilities can be inherited by anyone once the previous wielder is dead. These Titans consist of the Founding Titan, the Attack Titan, the Colossus Titan, the Armored Titan, the Female Titan, the Beast Titan, the Jaw Titan, the Cart Titan, and the War Hammer Titan. The 145th King that wielded the Founding Titan's power fled to the island of Paradis where he used the countless Colossus Titans to make the walls and erased the memories of the Eldians he brought with him so that they didn't know anything about the outside world.
