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.
It's annoying that I have 
to introduce myself to an angel,
Es widerstrebt mir, mich einem
Engel vorstellen zu müssen,
Me molesta tener que presentarme
con un ángel,
Me molesta tener que presentarme
con un ángel,
Quel ennui de devoir me présenter
à une ordure d’ange.
È una seccatura dovermi presentare ad un angelo,
Já é irritante me apresentar 
diante de um anjo,
Неприятно, что приходится представляться 
ангелу, но слушай внимательно.
