== Title ==
The original Japanese title, "Shingeki no Kyojin", has a dual meaning. The literal translation of the title is "Advancing Giant(s)" or "Attacking Giant(s)", with giants being Titans in the context of the series. In this way, the title can refer to both the advancing threat of the Titans or to a single attacking Titan.
== Plot ==
Roughly a century before the beginning of the series, a mysterious race of giant, man-eating humanoids, known as "Titans", suddenly appeared and nearly exterminated humanity. In order to protect themselves from this threat, the few survivors built three concentric Walls, called Maria, Rose, and Sheena, and encased themselves in this limited territory, forgetting everything about the outside world and the history before the building of the Walls.
In the present, a boy named Eren Yeager and his childhood friends Mikasa Ackerman and Armin Arlert dream about seeing the world outside the Walls some day; but their peace is abruptly interrupted when an unusual 60-meter tall Colossus Titan and an Armored Titan breach the outermost Wall, and Eren sees his mother dying in the resulting devastation. Eren vows revenge against the Titans and later enlists in the military branch Survey Corps, accompanied by both Mikasa and Armin.
As the story progresses, more mysteries surrounding the true origin and nature of the Titans, as well as the lost history of the world are addressed, and the reader gradually discovers that the Titans may not be the real enemies. Eren and the Survey Corps find themselves as the only remaining hope for their civilization, as they fight to uncover secrets from the past and stop the forces that want to bring about the destruction of mankind in the present and future.

== Development ==
Hajime Isayama came up with the idea for the Titans when a drunk man grabbed his collar in an Internet cafe. Isayama said he was inspired by the man’s inability to communicate and reason even though they were of the same species. This encounter led him to believe that “the most familiar and scary animal in the world is actually the human.” This idea is conveyed through the Titans: threatening beings which, despite their human-like appearances, lack any humanity. He also cited the visual novel and the manga as primary influences for his work.
The scenery for the story was inspired by Isayama’s own hometown in the mountains. He often desired to go beyond the mountains, which influenced Eren's wish to go beyond the Walls in the series. , the producer of the anime, said that the concept of being isolated and overcoming a "Wall of Fear" was also inspired by the isolated and enclosed nature of the Japanese culture.
Isayama first drew a 65-page draft of the story in 2006 and offered it to the department at , but he was advised to modify his style and story to be more suitable for the magazine. He declined and instead took it to the department at , where it was accepted and began serialization in the first issue of its monthly spin-off in September 2009. He was 23 years old and that was the first series he had ever published.
His monthly schedule consisted of one week for storyboard and three weeks for drawing. When designing the Titans, he got aid from a reference book for various human expressions; as well as inspiration from real-life models such as for Eren's Titan form, for the Armored Titan, or the anime's voice actors. He said that he chose giants as the theme for his work because "they are kind of gross." His early drawings were rough, and he himself admitted that they were "amateurish" and felt that they were "short of the standard required for commercial works"; but it has been noted that they have greatly improved over the years. His narrative puts much focus on the individual inner feelings of the characters.
Isayama has revealed that the story was planned far in advance and that he could even mark down in which specific volume a certain situation was going to happen; although it was not properly fleshed out until he was working on it. He had also planned a tragic ending for the series in which everybody would die, similar to that of the film adaptation of 's ; but after the manga and anime gained so many fans, he began to worry about the impact that such a conclusion could have on them, and grew unsure of whether he should have gone ahead with it. However, he admitted that he still liked the idea.
In September 2013, he stated that he wanted to end the series in Volume 20; but in June 2015 he claimed that the manga was "60% finished" at that point, and in September of the same year his editor Kawakubo Shintaro estimated that there were "about three years worth of manga chapters left"; which, if true, would mean that the manga would have ended around late 2018 or after at least 26 volumes. In December 2019, Isayama stated that he aimed to end the manga in 2020. In a June 2020 interview, Isayama confirmed that there was only 5% of the story left to go, and later 1-2% in November 2020. In January 2021, it was announced that the manga would end that April.
