'They want to become my slave?' Desire thought as confusion set in his mind.
After all, it basically said that even without The Demon's Oath, the demons would want to become his slave.
'They want...That's...kind of creepy.' Desire thought, but he decided to not just mind it.
He was not that affected right now, and this was something advantageous to Desire right now.
After all, that means that even William would want to become his slave.
However, that part didn't really answer Desire's question of how he would be able to release his control over William's body.
That was why...Desire was still stuck in this as he tried to look for other things in the Unknown.
It was then that Desire's eyes widened as he realized something. Since William was his slave now, William should be able to do whatever he wanted him to do.
And since Desire wants to release his control over William's body, William should be able to do something like that.
