Title
The original Japanese title, "Shingeki no Kyojin", has a dual meaning. The literal meaning is "Advancing Titan(s)" (or more literally, "Advancing Giant(s)"). However, it can also be taken as "Advance Toward the Titan(s)", which is what the localized title resembles: "Attack on Titan".

Plot
Around a century before the beginning of the series, a mysterious race of giant, man-eater 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 encaged 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, his adopted sister Mikasa Ackerman, and their friend 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 are probably not the real enemies. Eren and the Survey Corps find themselves as the only remaining hope for humanity, as they fight to discover the answers to these secrets and stop the forces that want to bring about the destruction of mankind.

Development
Hajime Isayama came up with the idea for the Titans some day when, while working at an Internet cafe, a drunk customer grabbed him by the collar. He said he was inspired by the lack of the ability to communicate even though the person was of the same species, and thought that the most familiar and scary animal in the world is actually the human. This is the feeling he conveys through the Titans: threatening beings which, despite their human-like appearances, lack any means of reasoning or communication. He also cited the visual novel ' and the manga ' as primary influences for his work.

The scenery for the story was inspired by his own hometown, which is surrounded by mountains. One day, he wanted to go beyond the mountains, which reflects Eren's wish to go beyond the walls in the series. , 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 draw 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 consists of one week for storyboard and three weeks for drawing. When designing the Titans, he gets 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 its 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 is planned way out in advance, and that he can even mark down in which specific volume certain situation is going to happen; although it is properly fleshed out until he is 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 ; 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 now he is unsure of whether he should go ahead with it. However, he admitted that he still likes 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 be ending around late 2018 or after 26+ volumes.
