リリス

The wife of the first Great Overlord Satan, and Zeabolos’ grandmother.

She was once an Overlord who held the Crest of Vanity, but she died during the battle when Trillion first appeared, and is now living within the Great Overlord’s castle as a ghost. She hates it when she's called "Grandma" because she does not look anything like an old grandmother at all, and instead retains her young looks even after dying.
