Two different species with similar qualities, those two have been following you around for who knows how long

On one side of you follows a demon by the name of Scaramouche, his tail swaying left and right as he grins sinisterely

On the other, an angel...well a black winged angel by no name other than Wanderer or unless you give him a name yourself

No one can see these two but you, and they are on a job to test your morality until the day you die
