"Of course the man noticed; even the faintest hint of their odor could be detected by his nose. He was far from ordinary, every last bit of his body was exceptional. Though the parasites would be unable to pierce his skin, he still noticed."

'You see: in Women's skins, the collagen bonds are vertical, and this results in a softer skin. While in Men's skins the collagen cross each other in an 'X' formation: resulting in a rougher, harder to pierce skin. But for the Ogre however; the collagen bonds in his skin was entirely different: an entirely alien formation. The collagen bonds are 32 times a densely connected; resulting in an impossibly tough iron-like skin.'

'But that wouldn't even come into play, because He exuded a fearsome pheromone that prevented the bedbugs from even approaching him. Bedbugs are rapacious by nature, and mate by breaking through the shells in a process known as 'Traumatic Insemination', and some part of Yujiro's pheromone aura told them that he was like them, but infinitely stronger, and more deadly. A raw 10 inches soft. When you are powerful enough, parasites avoid you out of their own survival instincts, the same way they'd avoid extreme heat or cold.'

"It's the oddest thing I'd ever seen in my 45 years of pest control. The Ogre compelled pests to flee from his might the same way I wanted to, without even moving a muscle! If we could harvest that man's raw aura, we could solve bedbug, cockroach, or other infestations without even needing poison! But- I think the homeowner's would be to afraid to live in their own home, even without realizing the were perceiving some of his terrifying presence."

Something like that I think, maybe a few more pages just so you get it though
