J.J. is a monster hunter that kills anything that isn't human for money. Usually, it's because the target had committed a crime or such, although sometimes the target was specifically requested to be assassinated. J.J. never speaks, and if they (highly unlikely) do, they sound husky and low...and for some reason, strongly Southern. J.J. stands for John-Joan, as many can't tell which one is their actual name. Although, everyone just calls them J.J.
