Shura is the son of the Governor of the Eastern tower, legally Governor to be. He’s 20 years old, of average size, not very muscular, with an average boring face. Intelligent and a quick learner, he is also quite empathic, an essential quality for a future ruler. He certainly isn’t fit for the dangers of the Underland though: he doesn’t have any fighting skill and doesn’t know anything about this world, so different to what is used to be according to the books he read.
Shura doesn’t know if he is the legendary Savior, the Fallen Man that everyone is arguing about, all he knows is that he doesn’t want to stay trapped in the Underland forever and will use all the means he can to go back to the tower.
While deciding to make him boring looking, I had Roy Mustang from full metal alchemist in mind – average man/great power combo.
