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!
It really eases my mind 
to have you around, Lilith.
Es ist tatsächlich besser,
wenn du dabei bist, Lilith!
Me siento mucho mejor contigo cerca, Lilith.
Me siento mucho mejor contigo cerca, Lilith.
Je me sens bien avec toi, Lilith.
Sono davvero felice di averti accanto, Lilith!
Me sinto tão melhor 
com você por perto, Lilith.
