It was this close to vanishing, and soon William heard the voice of the spirit, deep and slow, as if it didn't want to give out such a promise.
"Deal! You have my word, I'll step up to help you once, in return for such help."
"That's good," William evilly smirked, as he was indeed bluffing. He didn't have a way right now to cut the connection between him and that spirit. Yet luckily for him, the spirit didn't know anything about that connection, didn't know it wasn't something that could get severed or changed.
As the spirit said its last piece, it vanished. And yet William knew how to find it. It was inside his spirits, and it was expected for it to appear every single time he went to visit the Fate and Destiny world.
"Now… What shall I do with you?" As he finished dealing with the spirit, he turned around, and looked at his enemies, "who wants to die first? Who wants to serve me and live for a bit longer?"
