In a lot of ways, he's a typical shounen lead (although he's missing the spiky hair): he's not too smart, but his kindness, morals, and energy make up for it. His personality and cute character design seem like they would be more at home in Shounen Jump, deep within a happy manga about ninja or soccer. Instead, he ends up in a world full of war, cruelty, and difficult moral decisions. Obviously his character has to change over time to accommodate all this, but despite all the garbage he goes through he never loses his optimism and good nature.
