Women only affect my ability to spread the fire

An unusually thick fog gradually enveloped the world, and horrible demons emerged from it, plundering souls from people. Those whose souls were taken away lost their minds due to their hunger for souls and attacked others.
As the world begins its silent countdown, Russell travels here with a ball of fire. He unexpectedly discovers that the fire he brought with him not only poses a huge threat to the dense fog and demons, but can even restore sanity to those whose souls have been taken away by the demons, allowing them to become his followers...
But why do these women, after regaining their senses, all have improper thoughts about him?
Female scholars, female mages, female knights, female priests...
When the number of his harem (crossed out)... dependents increased, Russell wondered if this would affect his ability to pass on the torch.
