When Akari opens the fridge, she sees that there is no more blood.
But when Sophie tries to order it on her regular delivery site, she's met with a note that the service is currently inoperational.
Searching on other sites doesn't yield any results either. The next idea is to have Erie share some of hers, but she's also out.
Everybody is agonizing about what to do when Erie starts talking about finding a human downtown who wants to have their blood sucked...
It would be dangerous to get 
into the habit of sucking
سيكون من الخطير أن نعتاد على امتصاص
Wenn es zu einer Gewohnheit wird,
das Blut seiner Mitbewohnerin zu saugen,
Sería peligroso
si nos acostumbráramos a chupar
Sería peligroso acostumbrarse a chupar
Si je prend la manie de boire le sang
de l’humaine avec qui je vis,
Sarebbe pericoloso 
se prendessimo l'abitudine
Seria perigoso se nos
acostumássemos a sugar
Будет очень опасно, если 
привыкнешь пить кровь
