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.
She's the first choice when it comes
to angels you'd want to see fall.
Die Nummer Eins,
die ich fallen sehen wollte.
De los que quiero que caigan.
De los que quiero que caigan.
celle que je voulais voir chuter,
que je voulais torturer !
L'angelo che più desideravo cadesse.
A que eu mais queria que caísse...
Первая, кого хочешь увидеть падшей.
