In an era where the gluttonous spirits of the Frozen Hell cross into the mortal realm to devour humans... The world is protected by the Supreme God Indra(Jeoseokcheon) and the Four Heavenly Kings under his command, who fight against the gluttons of hell to maintain order. However, Indra(Jeoseokcheon) declares that the protagonist Nasua's younger sibling is the reincarnation of someone he once cherished and attempts to take them away. When Nasua grabs his sleeve to stop him, Indra(Jeoseokcheon) , displeased by her defiance, cuts off her arm. Nasua's hatred for the heavens reaches the farthest depths of Scorching Hell, the opposite of Frozen Hell. There, she is granted the arm of the Scorching Glutton, transforming her into something neither human nor glutton. Now, no longer belonging to either side, Nasua stands against the heavens, ready to fight the gods who battle against hell, all to reclaim her sibling.
