Totsuka Maria was praying in a chapel at Seiseki Girls' Academy when a black cross comes falling from the sky. On that cross, was a fallen angel, bearing the sin of pride, Lucifer. Maria attempt to tend to the angel, but the floor falls out and she disappears. Lucifer finds herself in the depths of hell, and runs into the Demon Lord of Envy, Leviathan.
I wonder what cries you'd
make as I pleasured you.
Welche Schreie der lüsternen Verzückung
dir wohl zu entringen sind?
¿Cómo serán tus gritos al complacerte?
¿Cómo serán tus gritos al complacerte?
Quel genre de cris pousseras-tu
quand je te donnerai du plaisir ?
Chissà come gemeresti
se potessi farti venire come dico io...
Quero ver como vai gemer 
com o prazer que te darei.
Интересно, как ты будешь стонать, 
когда я сделаю тебе приятно?
