The Unspeakable Take My Orders

Kai Hunter transmigrates into a world overrun by supernatural horrors and awakens a system that lets him do the unthinkable: summon and command them. Female ghost Samara, serial killer Freddy, creatures that cannot be stopped by anyone else now answer to him. As he tears through dungeons and dismantles shadowy organizations, a deeper truth surfaces about where the horrors came from and what this world actually is. By the end, Kai isn't just surviving the darkness. He rules it.
