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.
What type of blunder did 
you make to fall to Hell, Lucifer?
Was hast du angestellt, dass du
zur Hölle hinabgeworfen wurdest, Luzifer?
¿Qué habrás hecho
para caer al Infierno?
¿Qué habrás hecho
para caer al Infierno?
Quelle surprise
de la retrouver bannie en enfer.
Non posso fare a meno di chiedermi, Lucifer,
Exatamente o que você fez para 
cair para o Inferno, Lúcifer?
Но чтобы тебя, Люцифер, вдруг низвергли в ад... 
За какой такой поступок ты здесь?
