Prompt: Sora - it's not your fault, but it's your responsibility.
Sora knows it's not his fault.
It's not his fault that they exist. It's not his fault that they capture and swallow worlds whole. It's not his fault that they keep coming back, over and over. But somtimes it feels like it is.
... It's not his fault that there are so many Heartless, so many Nobodies, so many enemies that he's destined to fight and to defeat. He can't always be there to deal with them in every single world he passes through, but he knows that it's his responsibility to get rid of them. But that's the part that sometimes makes him stop and think, though he usually goes along without questioning - does it become his fault, then? Because the Heartless are after him, they swarm in the worlds all the more, like a throbbing wound, and he's the cure. It's a wound that won't close up completely whilst he's there, but will just get worse as soon as he turns his back and puts his attention elsewhere, to another world.
And each world he goes to, the pattern repeats. More Heartless. More Nobodies. More wounds to take care of.
Maybe soon there will be too many for him to handle.
Maybe there already are. There are so many places he hasn't yet been, crying out for help. Does being too late for them make it his fault?
It's not his fault that there are so many Heartless. Or is it?
Sora doesn't know.
He just hopes, really hopes, that no one will get hurt. Because even if it is his responsibility, he can't be there to stop them all the time.
