Runes used by the Orth city people (Orth runes) occasionally appear in the anime series and are direct match of the Japanese syllabic kana alphabets. The easiest way to decode them is reading the beginning and end titles with the names of anime staff as they are laid over the corresponding Orth runes. Since each symbol is a match for a kana sign, a native Japanese person or even anyone with a moderate knowledge of Japanese can easily decode them. As a result, a few people decoded them independently; the result could be found on the internet. Manga readers faced the problem earlier and thus found the solution first. There are some differences in style but in overall it is possible to read both manga and anime texts (if you know Japanese well enough to read it without kanji).

Table of Orth city letters and corresponding Japanese romaji

Written text is mostly used for illustrative purposes to create a mysterious look, but does not bring any significant new information. However, it is fun to read some short texts if you know Japanese or with help of internet translation tools. In the table above, the translation from Orth runes to katakana is presented, and below there are some examples of translated text.

In overall such type of writing are bad news for non Japanese community. Since runes are strictly linked to Japanese language there will be no texts which could possibly be in English.

Present examples are based on the anime version of the writing.

The first appearance of the runes in the anime is in episode 1 (9m 44s), where a book falls down and its cover is visible:

Awesome signature of Nanachi (ep.11 12m 07s):


There are funny things with books in anime series. Titles of books are all copied and there are only few original titles. One text is copied from poster in episode 1 and used later in episodes 7 and 13. ibetsukaishi??unokihan (please translate)

Death of Mitty is confirmed by the indicating lamp which turns off. Each lamp is marked with a name. It is strange that there is no lamp with Nanachi's name among approximately 30 readable tags. There are no names of Lyza and Reg (we do not know his real name) as well. Looks like all the lamps are indicating children of experiment or persons who descended below that level.
