Reincarnated as the Demon King's Testicles

It was supposed to be an isekai story like any other. Killer truck, rockin' goddess, and the good life as the next big fantasy hero. But that incompetent fool made a mistake on your reincarnation paperwork and sent you to a malfunctioning summoning circle in demon territory! Now you're just a spirit, stuck in a place where you really shouldn't be. How are you going to navigate this one? Localized Languages with Auto-Cards available.
