Fegor

Zeabolos’ older sister, and the Overlord who holds the Crest of Sloth.

She calls Zeabolos, "Zebo-chin", and she in turn is called “Sister.” She says little, but because she cares for her younger brother, she undertakes the task of defeating Trillion. She’s extremely lazy and is always sleeping, but she actually possesses powerful magic that can surpass even Zeabolos’.
