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 have to get tortured by trash like you just 
because I have the wings of an angel.
Wollen mich so Maden wie ihr misshandeln,
weil ich die Flügel eines Engels habe.
Una basura como esta debe torturarme
solo por tener las alas de un ángel.
Una basura así me tortura
solo por tener las alas de un ángel.
C’est à cause
de ces foutues ailes d’anges
Dover essere torturata da una miserabile come te
solo perché ho le ali di un angelo.
Só por ter as asas de um anjo
Жалкое ничтожество! Если собираешься пытать 
меня лишь из-за ангельских крыльев, то я готова!
