In world, there is a humanoid demon, that can enter both hell, and earth, with teleport ability. The demon itself looks scary, but he is not, everyone tells a myth, that this demon has most smoothest soles on his feet, much more than everyone. (But that could some dumb people's strange ideas.)

The demon is just kind, not harm one, who can make everyone happy, but he doesn't show himself often. And his voice, his voice is so soothing, and deep, but calm.
