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.
This is the lowest level of Hell, Cocytus,
where anything and everything freezes.
Ist auch die tiefste Tiefe der Hölle,
wo alles schwuppdiwupp einfriert, der Kokyitos.
Es el nivel inferior del Infierno,
Cocito, donde todo se congela.
Es el nivel inferior del Infierno,
Cocito, donde todo se congela.
On est dans le Cocyte,
la plus profonde strate de l’enfer.
È perché ti trovi nel Cocito, il punto più basso
dell'Inferno, dove ogni cosa diventa ghiaccio.
Esse é o nível mais baixo do Inferno, o Cócito, 
onde tudo o que existe congela.
Это низший уровень ада — Коцит. 
Тут всё и вся обращается в лёд.
