Only when Roy was finally done with all the women inside his personal chambers, and they were all sleeping on his due to extreme fatigue, did he finally lie down himself, and entered deep sleep.
What no one noticed was that when Roy finally decided to lie down and sleep his whole personal chambers were covered by some kind of illusion.
In that illusion Roy's body didn't appear to be on the location he fell asleep but much higher, as a preventive measure towards assassinations from outside.
As for the women inside, it was impossible for any one of them to even approach him, and even less threaten his life.
Furthermore, a large part of his Harem Palace had already accepted him as their man and was striving hard to catch his attention.
Anyway, no matter what, Foxy would always be there for him, guarding him against any possible danger, or unfaithful bi*tch.
