What mythical god is Hull?

The ruler of the land of the dead, Loki's daughter, Haier.

Loki married the giant Angrboda in Utanheim, and gave birth to three demon children (in descending order): one is Fimbul the Wolf, Yolmungander the world snake and Hull the goddess of death. Loki kept the secrets of the three children from God. But those three guys are growing fast, and they can't escape anyway. Odin also saw it on the throne. Knowing the benefits of these three evil seeds, he immediately found them, raised Hull in one hand and drove her into the depths of Naawer Heim, where she was the master of the underworld and the Lord of death. Odin threw the dream into the sea again, and the monster grew up in the sea until it coiled around the earth and could bite its own tail. Only Fimbul was taken to the sky, because Odin wanted to tame it, which might be of some use. When the gods saw Fimbul, they were all afraid of being eclipsed; Only Tyr is fearless. He feeds wolves.

Loki Rigel, a magic detective, is the eldest daughter of the evil god Loki, the "guardian of hell". She was born a half-rotting monster.
