He means the gems you sometimes see mamono wearing as jewelry. The dragon in the profile picture, for instance, is wearing a yellow one around her neck.

The answer is no, it's not some sort of regulator. It's a Devil Gem, a jewel that holds an enchantment of some sort. What's the one around her neck do? Dunno. The enchantments can pretty much be anything, whether it's stat boosting, resistance boosting, pleasure boosting, POWAH boosting, warm-fuzzy-feeling boosting, or whatever else.

It's not to protect her husband, though. She doesn't need an enchantment for that. Her Demonic Energy automatically handles any regulation needed to keep her from accidentally hurting her husband while they're up to "stuff".
