Riddle
Age: ??
Story: Terminal House

When TH actually takes place, Riddle has already found his answer and left the world, so in the story he only appears in conversation or small flashbacks.
The one that came before Riddle neglected him and eventually became a Lost Case, resulting in Riddle needing an outlet for his affection. When August is born, Riddle goes overboard when he finally has someone to love and moves too fast. Riddle finds his answer quickly and leaves August at an unusually young age.
Little is known about his personality. August's memories show Riddle constantly lavishing affection on him.

Riddle's demon is in his left arm, and his sin is "Taking".
