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 wanted to try an angel once.
Mit einem Engel wollt
ich schon immer mal.
Quería probar a un ángel una vez.
Quería probar a un ángel una vez.
J’ai toujours rêvé de savoir
quel goût a un ange.
Volevo solo provare un angelo, almeno una volta.
Sempre quis experimentar um anjo.
Всегда хотела повеселиться с ангелом.
