Tieflings are the reflection of Aasimars, where the Aasimar are kami-touched the Tiefling have the blood of Yokai flowing through their veins. Typically Tiefling seem themselves as the victim of some sort of cosmic joke or cruel prank. They're marked by the misfortune of a foolish ancestor who sought to broker a deal with a Yokai, or some other believed fantasy.
