The Archdemon of Envy, Invi, is the demon of jealousy, a master user of the water element and the one who invented the way to turn water into ice. Not only that, but also an ally of the Archdemon of Lust, a woman known for her great pride, Invi is also nicknamed the Queen of the Sea when she sits on the throne to unify all the seas.
The archenemy of the Archdemon of Gluttony, Gula, although both became Archdemons, they do not like each other. While the sea in Northrealm where one of Gula's children took over, Invi wanted to dominate it, this led to the act of encroaching on the territory and stealing land without permission, so the two went to war. Not only that, the war between the two sides caused many places to be affected.
But recently, Invi's attacks have not been seen anymore, the sea has become strangely peaceful.
Rumor has it that the sea became so calm because the Archdemon of Envy was plotting something bigger.
