Sorry, Karasu. You won't yet be with the Innocent Soul. Right now you'll be by yourself, unless you would rather go and search out the Ferryman. Either way, it isn't until the Charmer meets the Ferryman that he will be told of his job- which is to deliver the Innocent Soul to Hell, of course. He can go and fetch the Innocent Soul after his meet up with the Ferryman and Wayward Soul and then they can start their journey from there, or he can go back to meet up with the Ferryman and Wayward Soul after he has found the Innocent Soul. That is up to you.
