Sora

Sora is the main protagonist of the Kingdom Hearts series, and is one of many people who wields a Keyblade. Sora is a perpetually cheerful boy who is always enthusiastic and thoughtful, constantly thinking of others and valuing his friends above all else. In battle, his base keyblade is the Kingdom Key, though different keychains can be attached to change its appearance. Sora's home world is the Destiny Islands and he is best friends with fellow keyblade wielders Riku and Kairi. He is the main playable character in every entry of the series with the exception of Kingdom Hearts 358/2 Days (unlockable character), Kingdom Hearts Birth By Sleep, and Kingdom Hearts X.
