So this chapter confirms that his magic is Desire, not only pleasure, because pleasure and desire are two different things, Desire is a strong urge and impulse and Pleasure is joy or happiness. While I will admit it that it is an influence of sex, does not mean that those effected by it had sex, Just slaves to their pleasures.

So for each desire there is a feeling and an action:

Pleasure is the feeling for wanting sex

Hunger is the feeling for wanting food

Somnolence is the feeling for wanting sleep

Now this chapter was fairly going back and forth with each other, but the greatest surprise of all is at the end with Sting getting his power up from Rogue to achieve White Shadow Dragon Mode, actually, not that surprising since Dragon Slayers are capable of that.

Anyway, I doubt that Sting will win next week and we will see the Sleep magic from Larcade.
