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.
Now it's time to give that 
rotten angel that doesn't know
Nun soll der
verdorbene Engel erfahren,
Es hora de que ese maldito ángel
que no sabe cuál es su lugar
Es hora de que ese maldito ángel
que no sabe cuál es su lugar
Bien, faites goûter à cette bécasse
Ora è tempo che questo angelo infame,
che non sa stare al suo posto,
Agora é hora de mostrar tudo 
do que o Inferno é capaz
Ну что ж! Жалкий ангел, не знающий своего места... 
приготовься испытать всю боль ада!
