[I absolutely won't turn the cub into a lustful demon or something! I might be the demon lord of lust, but my power is way more than just lust, okay??]
Asmodeus was anxious to clear his name while also anxious to let his consciousness possess the little cub's body quickly.
Don't you guys realize that the stinky archangels had already left their summoning place and were rushing to the battlefield?
If they acted too slow, the chosen mediums would all die before they could give them strength!
Asmodeus' cries reminded the other demon lords about their urgent situation, and because of this, Atherton also didn't have a choice but to agree to Asmodeus's request.
[Okay, just do whatever you want, my lord. But please don't harm the little cub.]
He was afraid that Asmodeus's power would be too much for Ainsley and, in the end, it would harm Ainsley instead.
