Sylas' lip twitched. Maybe Cassarae was the only one capable of making him do such a thing. He had never heard something more ridiculous in his life. But honestly speaking, he really didn't know what, if any, sexually transmitted diseases a Demoness might carry.
It was a valid concern. Though this world seemed illness- and disease-free, that wasn't the case. It just meant that those who did contract illnesses and diseases tended to have some of the worst ailments under the sun.
One could imagine that the sort of diseases that would harm mortals and the like would be shrugged off by powerhouses like them. Meaning, the ones that could latch onto them, well…
They would probably kill anyone from pre-Summoning Earth instantly.
Even so, Sylas' Madness Control was to the point he could personally trigger his own autophagy and stop his sperm from leaving his body. If he had such a disease, he would know.
