In order to become a mage, you need a research theme which archives one of the seven deadly sins. While thinking about what his theme will be, Arata and 3 others are locked in a barrier, with no exit to be found. But then Lilith and the others find themselves needing to use the restroom... Good luck, girls!
The space we're in has been cut 
off by the barrier, I'm guessing.
Ich denke, diese Barriere
trennt den Raum selbst ab.
Debe ser una barrera que corta 
lazos con el espacio adyacente.
Debe de ser una barrera que corta 
lazos con el espacio adyacente.
Nous sommes en quelque sorte
coupés du monde extérieur.
Il luogo in cui ci troviamo è stato sigillato
 dalla barriera, probabilmente...
A barreira está dividindo os espaços, eu suponho.
