Numbers frequently have cultural meaning, which can include superstition and foreshadowing. Anime shows, being Asian-derived (Japanese, right), likely have more local meaning. China represents just one example of cultural number meanins (ref: wiki, chinese.SE)

The characters in Knights of Sidonia have numbers on their helmets, so I'm wondering if they are at all connected to the fates of the characters wearing them.

From the Wikipedia article the digits "2 and 8" in a number mean "double lucky", while the digit "0" is also lucky and even. Inspection shows that Nagate Tanikaze's helmet contains these three values.


The digit "6" (in Cantonese) is supposed to mean "to fall" have some unlucky connotations.

Is there a direct connection between the characters' fates and the numbers on the helmets they wear? Please provide details, clarifications, and references as possible.

Partial list of character names and helmet numbers:

  • Nagate Tanikaze, 028 in training, 704 as pilot
  • Shizuka Hoshijiro , 336 in training, 702 as pilot
  • Izana Shinatose, 291 in training, 723 as pilot
  • Yuhata Midorikawa, 256 in training, moves to command.

    I'm not sure what you're looking for. If you believe that there is some numerology superstition involved, the burden is on you to prove that your theory holds up. So Asians are superstitious about numbers, Japanese are Asians, Knights of Sidonia is a Japanese show. How is this and the numbers pertinent to the series? I don't see any solid connections.

  • The market is more than Japan. The cultures are related, exchange contents and ideas, and have shared lineages. The ideas of numerology are not unique, and show up in "show business" regularly across the globe. Aug 21 '15 at 12:39

    The primary target market for anime is the Japanese. All other audiences are secondary. By making reference to Chinese numerology, you don't establish how it is at all related to Japanese culture. While one is derived from the other, not all parts of the culture is equivalent. For an example, the number 9 is unlucky in Japanese, pronounced k(y)u, it is a homophone for "suffering/anguish" (苦), but the inverse is true in Chinese, the number 9 is a homophone of the word for "long lasting" (久), and as such is often used in weddings.

    I've made an edit to your question to clarify a connection between the helmets' numbers and the characters. If I changed the meaning of your question, feel free to change it back.

    @ʞɹɐzǝɹ - given the new form of the question, not opinion based, more references, excellent edit by Killua, - can you please take it off of hold? Aug 21 '15 at 17:29
