GriRea (グリレア) is a character that has yet to formally appear in Deep-Sea Prisoner's creations. She is the ruler of the Underworld and has an affinity for dogs.
GriRea has dark purple hair with an ahoge (cow lick), and she wears a purple and black crown. She has light purple-grey eyes and raceless white skin. She wears a long gradient purple long sleeved cloak without a hood with white horned skulls and red eyes at the bottom and purple flames. She also wears a long dark purple-grey mermaid dress with light purple-grey frills spilling out of the bottom.
It is unknown what relationship the two have. GriRea seems to have a one-sided rivalry with the Satanick.
Sibuna is GriRea's "loyal" subordinate.
- Before she was revamped, her name was Death Pater and she was a knight.
- She fights with magic.
- She was speculated to have some relation to Lavinrac due to the skulls.
- Her name is derived from the word "Grim Reaper"
