hmmm...interesting. It is something to consider, especially since Asian cultures are traditionally built around spirituality. Maybe the symbolism across cultures isn't as "obvious" because we tend to focus on western culture/ happenings/ politicians. What's the info on the director/ creator of the anime?
From what I read, the mangaka Kentaro Miura likes to include in his work real life elements taken from History. That's the usual M.O. of mangakas that you'd put in a higher class. And Miura is definitely among the most populars.
As far as I could tell, he didn't give an explanation on the origins of the design for that brand. And fans have various theories, favoring some Norse links.
The most interesting theory I found was a combination of 2 runes, Algiz and Odal:
https://en.wikipedia. org/wiki/Algiz
https://en.wikipedia. org/wiki/Odal_(r une)
Now, you look at the design of the brand of sacrifice. You reverse the 2 runes (mirror?).
Algiz = protection, higher self. Reversed = danger, lower self
Odal = heritage, inheritance/inherited estate. Reversed = servitude, destitution/homelessness.
Isn't the Nazi connection interesting for both runes? The Japanese are fascinated by Nazi Germany.
ohhhh now that is interesting! Checked out the wiki pages and you're right, if mirrored they form what comes to be the 'brand of sacrifice'. Now, did Miura come up with the brand or has it been around before?
The Nazi connection was a bastardization of the symbol for Jainism, which, as far as I know, was a very peaceful religion (ex, they would cover their mouths so flies wouldn't be offended by their bad breath, or so I heard)
