Forgive me if this is to disturbing, please ignore this if so. The question about demons made me wonder are there p*do demons who pray on kids or do they only go after adults?
I think this is actually a very interesting question! To find the answer, we should look at who created the demons and why they behave the way they do.
Demons were forged by the Divine of Lechery, Erasmos. He's a really pathetic guy, not because of his deformities but because of his nasty self-defeating attitude and misanthropic behavior. Instead of working on self-improvement and becoming someone worth loving, he decided to forge an army of sex slaves that he could use and abuse. These were demons--the incubi and succubi. Unfortunately for Erasmos, his monsters were just as flawed as himself. They turned on him and escaped into the world, where they prey on peoples worldwide.
Erasmos designed the demons to lust after loneliness and sexual frustration so that they would desire him most. They can smell these qualities and it attracts them like food, because to demons, sex is food. They will literally die without it, so they seek it out frequently and become volatile when it's denied to them.
But the thing about this is, the less satisfying the sex is, the less they are nourished by it. This is why demons become so parasitic after someone consents for the first time--they're now relying on that person to satisfy them sexually every night or else they will starve.
So, knowing all this, let's go back to your question. Are there pedophile demons? I'm going to say no.
These monsters don't view sex the same way peoples do. To peoples it's about pleasure and power, but for demons it's literally about survival. Despite their flaws they are still quite intelligent, and they're intelligent enough to know that children would be a waste of time in this regard.
A demon preying on children would be like an eagle preying on an ant in a field full of rabbits. Why would it waste time with a pointless crumb when there are full meals everywhere? There is nothing that a child could offer one of these creatures, especially considering children can't consent to sex anyway. A demon's victim must consent or else the demon can't initiate anything sexual--their natural "programming" won't allow it. This is why they get so pushy with their prey, and why they get violent when that prey says "no" after consenting previously.
