Walls writing

The  is the unofficial name given to one of the two known writings existent in the universe of the Attack on Titan manga, along with the unknown writing on the herring can. It is the writing used by the inhabitants of the Walls, appearing on a variety of items, as well as in the inside covers of the manga.

Description
The Walls Writing seems to be the official and possibly only writing used by the inhabitants of the Walls, since all known objects with text printed on them are written in this language; with the only exception of some extraneous items labeled in an unknown writing found in Utgard Castle, and perhaps also Ilse Langnar's notebook. The writing is composed by short, straight strokes and sharp corners. Since most labels written in this script are horizontal, it is presumably read horizontally. Nothing else is known about this script.

Appearances

 * The sign of a toolshop.
 * A signboard next to the boulder used to seal the gate in Trost District.
 * A signboard of the tavern where Levi and Kenny were fighting.
 * A book that Frieda was reading to Historia.
 * A newspaper that Armin was reading.
 * Bottles of Titan Serum.

Trivia

 * At first glance, the Walls Writing may look like unintelligible gibberish, although it is actually Japanese katakana turned upside down and messily written to make it difficult to read. By turning the text 180 degrees and some effort in the interpretation of the kanji from left to right, the writing can be directly translated to Japanese.
 * The texts seen in the newspaper Armin was reading and the book Frieda was reading to Historia are easter eggs added by Hajime Isayama's assistants which have nothing to do with the context of the story.
 * The inside covers of all manga volumes include pieces of Walls Writing revealing part of the lost history of humanity.Page_of_Ilse's_notebook.png
 * Eren_in_Titan_form_remembers_his_father's_fate.pnger possible case of the Walls Writing is found in Ilse Langnar's notebook. As she is running trying to reach Wall Rose after the failed 34th expedition beyond the Walls, she writes on her notebook a journal of her experiences. However, unlike other appearances of Walls Writing, Ilse's journal contains text that is instead katakana turned upside down and right to left, like the writing on the can of herring. While this has not been officially addressed, this is most likely an inconsistency on the part of Hajime Isayama's editors rather than a connection between Ilse and the goods at Utgard Castle.
 * When Hange Zoë is doing experiments to Eren Yeager in Titan form, Eren begins to write in the ground. The messages say that he cannot figure out how to harden his Titan form, followed by "What my father did to me." In one of the panels, Eren is depicted writing "ate" (クッタ), referring to how he was forced to eat his father, in a style similar to the herring can writing rather than the Walls Writing. This has also not been officially addressed, and is most likely an additional inconsistency on the part of Isayama's editors.
