I assume you didn't get the memo. Comics stopped being just for kids ages ago. Animation (cartoons) is well on its way from escaping the Age Ghetto as well. Comics and cartoons have become accepted and valued storytelling mediums, and readers like to see that characters are human too. (Well...human, hybrid, mutant, alien, high-energy beings, etc.)

True, Sora's story is strung together in the current three games, but there is a lot of room with both the Organization and with Riku's side to expand the story of Kingdom Hearts. Since the DS game seems to be focused on the Org13 and the PSP's Birth By Sleep is a prequel, it's pretty safe to assume Coded would be focused on Riku, DiZ or Namine, or even Radiant Garden/Hollow Bastion.
