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!
My, my. Arin-chan really did 
a number on us this time.
Liebe Güte, Arin-chan ist
wieder ganz schön bei der Sache.
Vaya, vaya, parece que 
Arin-chan hizo de las suyas.
Vaya, vaya. Parece que 
Arin-chan hizo de las suyas.
Ah là là…
Ehi, ehi... per una volta Arin-chan ha fatto il suo dovere...
De fato, Arin-chan realmente fez isso, não é?
