Evil Genius

Thanks a lot! Arvine is my favorite apostle （´v`人）♪

I thought Kushan Empire is influenced by the Kitai Empire in Guin　saga (a Japanese novel by Kurimoto Kaoru and the longest novel in the world). Miura once mentioned that he is a big fan of the novel, and used Nalisu (one of the character in the novel) as a model of Griffith. But yah, as the Japanese...

I think the boy isn't Guts and Casca's child nor Griffith because he is too grown up for that fetus.
Just like Schierke said, maybe he is an envoy from elfhelm...not so sure though(∀；)
