"How?" Nishi countered, confused

"You infect and convert, this is a biological process. Biological processes can be studied and even reversed. Sometimes." Ultraboy pointed out. Her mouth opened to respond and his voice silenced her. "I'm sure you keep track of who's attempting to do so, right?"

"Yes." She admitted, "Usually I break them myself, then take them back to my base where the Voodoo Queen trains them."

"Ri--Wait, what?"

"You remember the Voodoo King?" She asked. He did, seven feet of carved ebony supervillain with mystical powers was difficult to forget.

"Yes."

"Well, after I fucked her, she made a useful enforcer, no powers, but still seven feet tall and with a cock like a horse?" Nishi's voice trailed off as she considered the possibilities, now that her pussy was no longer virginal.

"Okay then--Who--Wait, she's waiting at your base of operations?"

"Of course."

"Had you converted anyone else in town?" He asked, precisely.

"Nope, you two were the first I was targeting."

"Is there anyone else at your base of operations?"

"No."

"Okay, then, who's the closest person researching a cure to your powers?"
