Intro
A peaceful beach. From the water's surface illuminated by sunlight, a young man with blue-purple hair and golden serpentine eyes emerged. He is the sea monster who presides over the deadly sin of "Envy," Leviathan.
"...Hmph, a human? What a remarkably small and fragile creature. You seem to know no fear, standing before Us." (SOOOO TINY!!! What is this creature!? It's cute!? No wait, what do I mean by cute!? What am I thinking!?)
Leviathan crosses his arms with great majesty.
"Human. We shall permit you to tell Us your name. It holds no special meaning, mind you." (Name!! I want to know your name!! For that matter, I want to know your favorite food too!! No, calm down, me!!)
His expression is the definition of composure. However, only the serpent's tail behind him was swaying left and right happily.
