Subaru had reached for the door, determined to save Rem from harm even if his current world would soon end. But instead of Rem, he found himself staring at Beatrice's library. Beatrice had remained silent throughout Elsa's attack and saved Subaru's life just moments before Elsa could claim it. Subaru shouts at Beatrice, demanding to know why she didn't help before everyone else was killed, and an intense argument ensues. Then Subaru catches sight of a familiar-looking book...
If they possess human and non-human 
blood in equal amounts,
،إذا امتلك دماً بشرياً وغير بشريّ بنسبة متساوية
Wenn man gleich viel menschliches
und anderes Blut hat, ist man eingesperrt.
Si poseen sangre humana
y no humana por igual,
Si poseen sangre humana
y no humana por igual,
Un être sera rejeté s’il possède du sang
humain et demi-humain à parts égales.
Chi possiede sangue umano 
e non umano in parti uguali
Se alguém tiver o sangue humano e
não humano em proporções iguais,
Тому, в ком поровну человеческого
 и иного, не выбраться наружу.
