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.
Everyone hates me up in Heaven...
Im Himmel bin ich
bei allen unten durch.
Todos me odian en el Cielo…
Todos me odian en el Cielo…
Maintenant que je suis plus
en odeur de sainteté au paradis,
Lassù in Paradiso mi detestano tutti...
Todo mundo no Firmamento me odeia...
На небесах меня все возненавидели, 
а в аду уже есть поклонники?
